Pandemonium — The Howling Labyrinth

Pandemonium is wild and noisy disorder made into a world: an infinite cavern labyrinth where winds collide, voices lose their meaning and every direction offers confusion rather than escape.

Its endless uproar expresses alienated chaos. Unrestricted movement destroys direction, communication breaks into accusation and freedom without responsibility leaves travellers isolated within a realm that never becomes still.

Overview

Pandemonium is uproar without release.

It is an immeasurable interior of caverns, tunnels and sealed hollows. Wind tears through every open passage. It whispers through hairline cracks, screams through narrow galleries and roars across vaults large enough to swallow cities.

Currents collide, divide and reverse. Dust, stone fragments, lost possessions and the wreckage of failed expeditions travel through the dark. A warning shouted into one passage may return from another direction after the danger has moved elsewhere.

There is no sky, planetary surface or universal horizon. A distant darkness may conceal the opposite wall of the same cavern. A passage that appears to descend may curve until its wall becomes the ground beneath a traveller’s feet.

Gravity pulls away from the central void of each cavern and toward the surrounding stone. Travellers can stand upon the floor, walls and ceiling of the same chamber. Where passages intersect, competing gravity fields can change the meaning of up and down without warning.

Pandemonium possesses no ordinary natural light. Open flames are rapidly extinguished. Enclosed lamps and magic survive more reliably, but a steady light may reveal travellers across an immense cavern long before they see what approaches them.

The plane transforms sound into geography. Residents recognise routes through pitch, vibration, pressure and echo delay. Voices travel across impossible distances while losing context and identity. A familiar call may belong to an echo, predator, remembered event or person who disappeared generations ago.

Movement is abundant. Escape is not.

Most inhabitants are exiles, prisoners, refugees or travellers who have lost the knowledge, allies or trust required to leave. The labyrinth offers countless directions but few dependable routes.

A small number of isolated communities endure. Every permanent refuge is remarkable, vulnerable and separated from its nearest neighbour by dangerous travel. Their people survive through maintained anchors, sealed doors, shared signals and carefully defined obligations.

Every stable refuge is an argument against the plane.

Cosmic History

Eon VII — The Birth of the Howling Labyrinth

Pandemonium crystallises during the formation of the Outer Planes, when enduring moral and conceptual forces acquire permanent geography.

Chaos and possibility supply unrestricted movement. Fractured thought divides voice from meaning and motion from direction. Conflict gathers wherever confusion hardens into accusation, hostility and abandonment.

The resulting plane contains endless passages but no dependable escape. Freedom survives, yet fellowship must be rebuilt deliberately.

Eon X — The Coming of Elemental Air

Pandemonium’s winds predate the Elemental Plane of Air.

They are part of the plane’s original conceptual geography: movement trapped inside stone, pressure without release and noise without mutual understanding.

When the Elemental Planes emerge during the Elemental Foundations, later breaches connect the labyrinth to Elemental Air. Air-born beings then begin entering as migrants, summoned servants, explorers and captives.

Eon XIII — The Elder Wars

During the Elder Wars, planar engines and divine armies seal unstable breaches throughout the multiverse.

Some pockets of the Sealed Dark become wartime prisons. Dangerous beings, weapons, voices and records are placed beyond ordinary travel. Abandoned shelters later become the foundations of mortal and outsider refuges.

Damaged engines leave pressure reversals, unstable gravity junctions and portals connecting regions with no natural relationship.

Eon XIV — The Cosmic Leylines

The Cosmic Leylines reinforce reality after the Elder Wars. Silver cords, runic anchors and guarded junctions stabilise damaged planar boundaries.

The oldest anchors used by the Hanging Havens are surviving fragments, later adaptations or smaller constructions based upon those ancient principles. Refuge builders cannot reproduce the original works, but they understand enough to secure inhabited caverns against changing pressure.

The Last Anchorage surrounds one surviving stabilisation junction. Its runic wall predates the settlement built against it.

After Eon XIV — The Long Age of Refuge and Exile

When the Elder Gods withdraw during the Great Retreat, their leylines, anchors and wardens remain behind.

Only a fraction of Pandemonium lies within their protection. Leywardens and runic sentinels patrol isolated routes, while damaged junctions produce repeating portals, sudden gravity changes and currents crossing regions that should remain separate.

Settlements gather around the few anchors that continue to function. Most disappear after a failed seal, redirected storm, internal division or broken supply route. Their ruins become salvage sites, predator territories and memorial chambers.

The Age of Exile and Rebellion

During the Age of Exile and Rebellion, outsider peoples split into rival hosts and compete for influence across the planes.

Pandemonium becomes a refuge, meeting ground and disposal site for those whom established realms refuse to receive. Defeated servants, escaped prisoners, broken companies, failed negotiators and displaced communities enter through unstable crossings.

Some establish temporary shelters around surviving anchors. Others disappear into the Carved Lament or are confined inside the Sealed Dark.

Several Hanging Havens trace their customs of sanctuary, shared-line duty and temporary emergency authority to this period. Their founders learn that unrestricted freedom offers little protection unless people also accept defined obligations toward one another.

The First Worlds

As stable worlds emerge, Pandemonium begins accumulating what other parts of creation lose.

Failed settlements contribute wreckage, sealed records, damaged instruments and displaced inhabitants. Splinter Storms carry fragments from one cavern system to another, distributing evidence from places that possess no surviving route between them.

Later Material worlds provide new languages, crafts, laws and rivalries. Some travellers escape after brief expeditions. Others become stranded, join existing refuges or establish settlements that survive for only a few generations.

The Mortal Ages

As mortal kingdoms grow, controlled gates are used to transport prisoners, spies, dangerous witnesses, inconvenient heirs and condemned objects.

Many of those passages are later destroyed or forgotten. Their captives retain freedom of movement within the labyrinth but possess no road home.

The Carved Lament accumulates mistranslated warnings, contradictory treaties and messages spoken by people whose descendants no longer share the same language. Writing, physical tokens and witnessed signals become more valuable than ordinary speech.

Divine powers use the plane as neutral ground, concealed passage and temporary sanctuary. None gains authority over the whole labyrinth.

The Present Age

Pandemonium remains ancient and active.

Cosmic anchors fail and require repair. Havens rise, divide, vanish and are rebuilt. Howler territories shift when collapses open new hunting passages or destroy old memorial chambers. The Sealed Dark still contains prisoners whose judges, jailers and sentences have been forgotten.

New breaches open through mining, siege work, earthquakes and the excavation of older ruins. A doorway beneath a castle, city wall or mountain mine may expose its surroundings to the Outer Howl or open directly into a prison sealed before Earth existed.

Every age sends new voices into the labyrinth, and the labyrinth returns them changed.

Place Among the Outer Planes

Plane	Cosmic Expression
Limbo	Mutable possibility and freedom capable of creating new form.
Pandemonium	Uproar and confused motion that divide direction, communication and fellowship.
The Abyss	Predatory appetite, corruption and destructive freedom sharpened into Chaotic Evil.
Carceri	Captivity, betrayal and imprisonment maintained by prisoners and jailers.

Carceri confines through captivity. Pandemonium isolates through disorder and failed connection. Its inhabitants may possess countless paths while lacking any trustworthy way to choose among them.

Planar Laws

The Infinite Interior

Every known region lies inside stone.

Caverns open into greater caverns. Tunnels narrow, divide and converge. Some passages appear naturally formed, while others bear cuts, grooves and tool marks left by unknown builders.

No verified expedition has reached a universal centre, outer crust or final wall. Scholars disagree over whether the plane is physically infinite or folded repeatedly through itself.

Wind and Pressure

Pandemonium functions as one immeasurable pressure system. A sealed door, opened tunnel or distant collapse can alter airflow across inhabited regions far beyond sight.

• Murmur Winds: Persistent currents carrying dust, scent and distant sounds
• Howling Winds: Powerful flows hindering speech, hearing, exposed flames and movement
• Violent Winds: Currents capable of lifting unsecured creatures and driving debris through galleries
• Killing Winds: Catastrophic fronts carrying broken stone, metal, bones and wreckage
• Pressure Reversals: Sudden changes exposing sheltered surfaces and slamming doors against their frames
• Splinter Storms: Moving fronts of stone, glass, bone, metal and abandoned equipment

A passage opened for escape may redirect a storm toward an unseen refuge.

Gravity

Gravity pulls away from the central void of each cavern or passage and toward the enclosing stone.

Travellers can stand upon the floor, walls and ceiling of the same chamber. Where caverns intersect, competing fields may release a traveller from one surface and pull them toward another.

Light

The caverns are ordinarily completely dark.

Open flames are rapidly extinguished. Enclosed lamps, magical illumination and rare luminous organisms can survive, but a steady light may be visible across an immense cavern and attract creatures beyond the travellers’ sight.

The Blackwater Deeps absorbs light rather than reflecting it.

Sound

A spoken word may vanish immediately or travel for miles through a resonant passage. Echoes overlap, divide and return from unexpected directions.

Most apparent voices come from wind moving through cracks, carved channels and abandoned structures. Others belong to creatures, retained memories or people speaking in distant caverns.

Residents verify identity through hand signs, written passwords, light codes and physical tokens rather than trusting a voice alone.

Hearing protection is standard equipment. Prolonged exposure to the full howl risks deafness and lasting injury.

Time

Time advances normally through most known regions, but the absence of daylight and seasons makes its passage difficult to judge.

Refuges use guarded clocks, measured water flow, pendulums, work shifts and distinctive bells. Local distortions occur around damaged portals, wartime prisons and ancient stabilisation works.

Food, Water and Air

Water comes from mineral seeps, condensation systems, underground streams and imported cisterns.

Food comes from fungus beds, pale cavern animals, edible lichen, preserved stores and imported livestock protected within sealed chambers.

Breathable air, water and cultivated space are strategic communal resources. Their control shapes local law more strongly than conventional treasure.

The Four Layers of Pandemonium

Pandemonium descends through the Outer Howl, the Carved Lament, the Blackwater Deeps and the Sealed Dark.

The first three layers blend gradually into one another. Their boundaries are recognised through changes in cavern shape, sound, moisture, stone and pressure rather than fixed gates.

The Sealed Dark contains no continuous cavern network. Its isolated pockets lie enclosed within solid stone and are normally reached only by portals, powerful excavation or deliberate planar passage.

The Outer Howl – the first layer of Pandemonium

The Outer Howl is the broadest and most accessible layer.

Its natural caverns are larger than those of the deeper layers, and most known portals open somewhere within it. The majority of the plane’s rare refuges stand here.

Even this layer remains sparsely inhabited. Its Havens are divided by enormous distances, unstable routes and caverns claimed by darkness, wind and predators.

Howler packs patrol some darker passage systems. Their vibration calls travel through stone beneath the ambient roar, allowing a hunt to begin before travellers hear any creature approaching.

Scale and Exposure

The greater size of the Outer Howl’s caverns gives travellers more room to move, but it also leaves them exposed across immense distances. A passage may open onto a vault whose opposite wall lies beyond the reach of ordinary light. Floors, walls and ceilings form separate gravity surfaces around the same central darkness, allowing distant travellers, settlements and predators to move above, below and around one another without sharing the same route.

Large caverns do not produce open landscapes in the Material Plane sense. Stone still encloses every direction. The apparent horizon is another wall, a curving ceiling or darkness concealing a gravity surface too distant to see. A party may travel for hours around the interior of one vault without reaching the passage visible across its centre.

The layer’s scale also magnifies the wind. Currents gather strength while crossing broad chambers and compress violently when they enter narrower tunnels. A cavern that feels almost still near one wall may contain a powerful stream through its centre or a pressure front moving slowly towards an inhabited ledge.

Darkness removes ordinary measures of distance. A lamp may appear close enough to reach and remain several miles away. A moving light may belong to another expedition, a Haven signal, loose equipment carried by the wind or a creature using illumination recovered from earlier prey.

Arrival Without Orientation

Most known portals into Pandemonium open within the Outer Howl, but few deliver travellers to a prepared landing place. An opening may appear upon a narrow shelf, against a vertical gravity surface or inside a cavern crossed by several competing currents.

The first challenge is orientation. New arrivals must determine which stone surface currently holds them, where the strongest wind is moving and whether the portal will remain open. A visible Haven may stand upon another gravity face with no direct crossing between the two.

Pressure commonly changes when a portal opens. Air may rush towards the breach, burst outward from it or begin circulating through passages that were previously still. Loose possessions can be pulled back through the opening, while dust and debris from Pandemonium may be driven into the world beyond.

Stable portals become valuable without becoming dependable. A gate used repeatedly may shift its destination within the same cavern system, open only during a particular pressure cycle or cease functioning after a collapse alters the surrounding stone. Knowledge of a portal therefore includes its warning signs, expected arrival conditions and the circumstances under which it becomes unsafe.

Crossing the Outer Howl

Travel through the Outer Howl follows sequences of physical conditions rather than permanent roads. Guides remember changes in airflow, mineral texture, echo delay, temperature and gravity. Route instructions describe actions that must be taken at the correct moment:

Follow the warm current until the stone begins to hum. Cross to the opposite gravity face during the third pressure lull. Take the narrow fissure after the wind turns cold.

A route can fail while every passage remains physically open. A current may reverse, a familiar echo may disappear or a gravity transition may place the next tunnel beyond reach. Markers survive best when they can be recognised by touch or from several orientations, but even a correctly identified marker may no longer point towards a usable crossing.

Maps remain useful around stable Havens and heavily travelled junctions. Across the greater wilderness, written route instructions, recent observations and knowledge of current pressure conditions are more valuable than a simple drawing of connected tunnels.

The principal danger is accumulated exposure. Each delay consumes protected light, water, food, rope and the strength required to resist the wind. A failed journey need not end in immediate death; it may instead leave the party approaching a Haven after its doors have sealed, crossing an exposed vault during a pressure reversal or entering a passage already claimed by predators.

Isolation also changes the value of information. A warning from another traveller may be months out of date, yet remain the best guidance available. An abandoned camp can reveal the direction of a refuge, the failure of a route or the presence of a danger that has since moved elsewhere.

Refuge Across the Distance

Most of Pandemonium’s known Havens stand within the Outer Howl because its broad caverns provide more opportunities for stable anchors, sealed chambers and defensible living space. Their presence does not make settlement common. Each refuge remains an isolated exception surrounded by enormous reaches of uninhabited stone.

A Haven affects the wilderness around it long before its walls become visible. Maintained warning signals, secured crossing points, salvage marks and emergency shelters show that organised life lies somewhere ahead. Beyond those limits, travellers depend upon their own equipment and agreements.

Contact between Havens is irregular. A route that once required several days may remain closed for years after a collapse or gravity shift. Messages travel through guides, expeditions, written packets and recognised signals, but every settlement must be capable of surviving long periods without help from its neighbours.

This separation prevents the Havens from becoming a unified civilisation. Customs, emergency authority and standards of hospitality develop locally. A traveller recognised as a guest in one refuge may arrive as an unknown risk at the next.

The distance between Havens creates opportunities as well as danger. Ruined shelters, failed anchorages and abandoned supply chambers remain scattered through the layer. Some contain useful stores or route records. Others survive as evidence of decisions whose consequences are still disputed by neighbouring communities.

Howlers Beneath the Roar

Howlers favour the darker passage systems linking the Outer Howl’s great caverns. A pack may control an extensive hunting range without appearing near every route within it.

The wind makes ordinary hearing unreliable, but Howler communication travels through the stone. Pressure pulses and resonant vibration pass beneath the audible roar, allowing pack members to exchange warnings and coordinate movement through connected passages.

A hunting pack may become aware of travellers through repeated footsteps, driven pitons, dragging equipment or impacts transmitted along a cavern wall. The party may hear nothing unusual while the pack determines its direction and moves towards a favourable interception point.

Howlers use the geography rather than simply charging through it. A pack can follow travellers from beyond the range of their lights, approach through passages hidden upon another gravity surface or wait near a crossing where wind and unstable footing restrict movement.

Evidence of Howler activity includes repeated scratches at a consistent height, fragments of prey carried into sheltered cracks, vibration calls felt through anchored equipment and sudden silence among smaller cavern animals. Such signs indicate a hunting territory rather than the exact position of the pack.

Individual packs differ in conduct. Some defend recognised boundaries and allow travellers to withdraw. Others pursue prey across several cavern systems. A guide who understands one pack’s signals cannot assume that another uses the same warnings or accepts the same terms.

The Descent Inward

The Outer Howl has no single lower gate. Its broad natural caverns narrow gradually into denser and increasingly resonant passage systems until travellers enter the Carved Lament.

The change becomes apparent through sound and stone. Open roars sharpen into whistles and sustained cries. Natural curves give way to cut channels, tool marks and unfinished chambers. Voices begin travelling through the rock with greater clarity while losing any reliable connection to their source.

Some routes cross between the two layers several times. A broad natural cavern may open beyond worked passages, while a carved gallery may reach upward into the Outer Howl. Travellers recognise the deeper layer when worked stone and directed resonance become the dominant features of the journey.

The transition changes the nature of danger. The Outer Howl threatens through exposure, distance and uncertain crossings. The Carved Lament confines those same winds within narrower passages, where sound becomes sharper, more persistent and easier for others to manipulate.

The Gale Mouths

The Gale Mouths are colossal junction caverns where several pressure systems meet.

Opposing currents create standing waves capable of throwing travellers between gravity surfaces. Guides identify individual mouths through pitch, temperature, mineral taste and the rhythm of debris striking stone.

Observation chambers maintain warning bells and shutter signals. Deliberately imitating those signals is a serious offence among nearby refuges.

Later breaches to Elemental Air appear most often here. Air-born migrants may seek a route home, follow an old command or claim a current as territory.

The Shatter Galleries

The Shatter Galleries are passages lined with brittle mineral shelves.

Powerful currents break them into sharp fragments and keep them airborne. During severe pressure surges, whole galleries become rivers of stone blades.

The galleries contain valuable minerals, but careless excavation can redirect wind toward a refuge or weaken the stone supporting it.

Cave Fishers transplanted through old gates sometimes establish themselves above sheltered ledges, bridge approaches and narrow shafts.

The Hanging Havens

The Hanging Havens are a small number of independent settlements suspended within comparatively stable vaults.

Some hang from chains and natural arches. Others occupy several gravity surfaces at once. Enclosed bridges, reinforced shafts and counterweighted lifts connect their districts.

The Havens do not form a unified civilisation. Each may lose contact with its neighbours for years.

Several laws are nevertheless widespread:

• Public anchors and pressure doors receive the highest protection.
• Emergency shelter cannot be seized casually from a recognised guest.
• Forged rescue calls and false alarms are serious offences.
• Opening an external door during a storm requires recognised authority.
• Anyone accepting sanctuary must obey emergency commands while the refuge remains sealed.
• A traveller attached to a shared anchor line owes reasonable aid to others upon that line.
• Structural or atmospheric danger threatening another district must be reported.

The Havens offer the safest known rest while generating disputes over asylum, public duty, limited air and emergency authority.

The Turning Galleries

The Turning Galleries undergo repeated changes in wind direction and local gravity.

A sheltered floor can become an exposed wall. A descent may become a climb during the return journey. Camps survive only when equipment and sleepers are secured to more than one surface.

Experienced guides place route marks where they remain visible under several orientations.

The Uncertain Crossings

The Uncertain Crossings are temporary junctions where routes, portals and gravity fields overlap.

Some remain open for hours. Others exist for less than a minute. Travellers may see several destinations through the same opening while the wind pulls objects toward each of them.

Eshu, divine messenger and keeper of crossings, occasionally appears at these junctions. He maintains no realm in Pandemonium.

Temporary shrines mark places where travellers must listen carefully and honour the exact terms of a bargain. Eshu tests attention, adaptability and reciprocal obligation rather than pursuing isolation as an end in itself.

A careless traveller may receive the route requested while losing the destination intended.

The Carved Lament – the second layer of Pandemonium

The Carved Lament lies beyond the broad natural caverns of the Outer Howl.

Its passages are narrower, more numerous and far more resonant. Many appear to have been cut deliberately through the stone. Chisel marks, geometric channels and unfinished chambers remain visible, but their makers are unknown.

The restricted tunnels sharpen the winds into cries, laments and piercing whistles. Sounds travel unpredictably through the carved network, allowing voices to reach chambers far from their source.

Howlers favour passages where carved channels carry vibration between disconnected rooms. Packs use these channels to surround prey, declare boundaries and exchange warnings.

The Worked Stone

The Carved Lament begins where the broad natural caverns of the Outer Howl narrow into dense networks of worked stone. Chisel marks cross walls too large for mortal tools, while geometric channels run through floors, ceilings and pillars without revealing a consistent purpose.

Some chambers appear finished, with polished surfaces, exact proportions and deliberate acoustic effects. Others remain incomplete. Tool cuts end halfway across a wall, stairways stop above empty shafts and carved doorways open onto solid rock.

Natural caverns and worked passages overlap throughout the layer. A precisely cut gallery may descend into an untouched fissure before emerging into another chamber shaped by unfamiliar methods.

Much of the carving interacts with the wind. Channels divide a single current into several tones, ridges make the stone hum and narrow openings transform distant pressure changes into cries that continue after the original gust has passed.

The builders and their purpose remain unknown. Whatever their original intention, the Carved Lament now functions as a vast instrument played continuously by Pandemonium itself.

Sound as Geography

Sound forms part of the Carved Lament’s geography. A passage may be recognised as readily by its pitch and rhythm as by its shape. Guides listen for sustained notes, returning echoes and changes in vibration to identify junctions hidden beyond the reach of their lights.

Carved channels carry sound far beyond its natural range. A spoken word may disappear from the chamber where it was uttered and emerge clearly from a wall several passages away. Footsteps may travel ahead of the person making them, while a hammer strike can return later from a route the travellers never entered.

Different sounds follow different channels. A passage that carries speech may swallow the noise of armour. A wall that transmits a Howler’s vibration may conceal the approach of another expedition. Guides test several tones and surfaces before trusting an unfamiliar route.

The layer also preserves fragments of speech. Names, warnings, arguments and cries may continue moving through its channels after their speakers have departed. Most decay into distorted sounds, but some remain clear enough to be mistaken for living voices.

Travellers use agreed phrases, repeated rhythms and visual or tactile signals to confirm identity. A familiar voice calling from an unseen passage proves little unless it can answer a question chosen after the group entered the layer.

Messages sent through the stone remain unreliable. Words may divide between several routes, arrive out of order or combine with older echoes. Silence can be equally significant: when a familiar resonance suddenly disappears, a passage may have collapsed, flooded or been sealed.

Travel Through the Carved Passages

Travel through the Carved Lament is confined but rarely straightforward. Passages branch repeatedly, loop through different gravity orientations and reconnect at unexpected levels. Several routes may run beside one another while remaining separated by walls too thick to breach.

Maps record chamber shapes and intersections, but acoustic instructions are often just as important:

Take the left passage where your footsteps return twice. Climb when the wind begins to whistle through the floor. Turn away from the voice that repeats your last word.

Carved signs occur throughout the layer. Some indicate airflow, depth or structural danger. Others belong to abandoned expeditions, vanished settlements or unknown builders. Later travellers add their own marks, creating clusters of competing instructions around difficult junctions.

A failed route usually leads somewhere rather than ending completely. Travellers may arrive in the wrong gallery, descend farther than intended or emerge behind a sealed refuge. The cost appears through lost time, depleted supplies, unwanted attention and separation from reliable landmarks.

The narrow passages make retreat difficult during storms or pursuit. A group that blocks a corridor may trap itself alongside everything following behind it. Camps therefore favour chambers with several exits, defensible side passages and stone surfaces capable of carrying warning vibrations.

Howlers in the Resonant Channels

Howler packs use the Carved Lament’s stone channels to extend their vibration calls through walls and across branching passage systems.

A pack may spread through several parallel galleries. Some members drive prey forward while others listen through the stone and move towards likely escape routes. Travellers may believe they have left the predators behind while moving deeper into an organised hunt.

Experienced travellers attempt to confuse these signals by suspending equipment away from the floor, varying their pace or creating vibrations along several passages. Such measures may delay a pack, but they rarely defeat creatures familiar with the local stone.

Scratches, scent marks and repeated low-frequency pulses may indicate a pack boundary. Recognising these warnings can allow travellers to withdraw before the hunt begins, although the behaviour of one pack does not establish the conduct of another.

Strife Beyond the Court

Eris rules the divine enclave of Strife within the Carved Lament, but her authority does not extend across the entire layer. Her influence travels farther than her borders through messengers, rumours, provocations and disputes carried between isolated communities.

Some travellers approach Strife seeking advantage over a rival, judgement in a dispute or an answer that will force hidden tensions into the open. Others avoid every route associated with the enclave, knowing that even a truthful message can cause conflict when delivered at the right moment.

Momus appears elsewhere in the Carved Lament as an exile, critic and disruptive observer. His mockery may expose a dangerous weakness, undermine an agreement or reveal that a respected custom has never worked as its defenders claim.

Neither Eris nor Momus creates every quarrel within the layer. Isolation, unreliable communication and dependence upon shared passages generate conflict without divine intervention. Strife gives some of those disputes direction, symbolism and a wider audience.

The Descent Towards the Blackwater Deeps

The approach to the Blackwater Deeps begins where the carved passages descend into colder stone and the sound of moving water joins the wind. Damp surfaces appear first, followed by narrow channels, flooded shafts and black pools filling the lowest parts of chambers.

Familiar acoustic landmarks become muffled by water. A route once identified by its echo may fall silent after a lower chamber floods, while currents heard through the stone may reveal passages hidden beneath the surface.

Wind continues to move through these tunnels, carrying cold spray and the mineral scent of deep water. Worked stairs descend beneath black pools, drainage channels open into unseen caverns and abandoned anchor points suggest that some routes were used before their lower sections flooded.

Travellers enter the Blackwater Deeps when water ceases to be an occasional obstruction and becomes the dominant force shaping movement, sound and survival. The cries of the Carved Lament fade behind them, replaced by dark currents and the movement of unseen bodies below.

The Echo Vaults

The Echo Vaults are resonant chambers where sounds outlast their speakers.

Some voices fade after minutes. Others repeat for centuries. Powerful echoes can attach themselves to a place, name, family, object or event.

Travellers communicate through signs, writing and physical contact. Speaking a true name openly is considered reckless.

The Choir of Lost Names

The Choir is a vast carved cavern filled with overlapping voices naming people who disappeared within the labyrinth.

Some names sound once. Others return in cycles. A few answer questions using fragments of previously heard speech.

Families and rescuers visit seeking evidence of the missing. The voices provide clues rather than certainty: a name may have been spoken by a companion, victim, captor or imitator.

The Black Bell Caverns

Enormous hollow mineral formations hang from the roofs and walls of these caverns.

Pressure changes cause them to toll without being struck. Interpreters compare sequences of tones to predict collapses, portal events and movements in deeper stone.

Fallen fragments are valuable in warning devices and acoustic magic. Several refuges protect the bells as ancestral monuments or records of disasters survived.

The Whisper Scar

The Whisper Scar is a narrow fissure passing through hundreds of connected chambers.

Sounds entering it return as intimate whispers near a listener’s ear. The Scar preserves secrets, fears and accusations more faithfully than their original context.

Investigators and grieving families seek answers there, often discovering a true fragment supporting a false conclusion.

Strife — The Court of the Unanswered Apple

Eris, goddess of destructive strife and discord, maintains a divine enclave within the Carved Lament known as Strife.

The enclave consists of echoing council chambers, divided galleries and ceremonial courts in which every statement returns altered by resentment. A careless word may reach the listener least able to forgive it. An apology may return as an accusation.

At its centre stands the Court of the Unanswered Apple. Black tables are divided by deep channels, forcing delegations to cross exposed bridges before they can meet.

Golden apples appear when alliances begin to fracture. Each bears a title, insult or claim capable of turning existing rivalry into open conflict.

Eris uses Strife as a refuge, meeting place and point of departure for her agents. She rules the enclave, not Pandemonium or the wider Carved Lament.

Momus — The Unwelcome Guest

Momus, god of satire, mockery and criticism, maintains no recognised realm in the plane.

He sometimes takes refuge in the Carved Lament after banishment from Olympus. His disembodied voice exposes hypocrisy, false authority and concealed motives, often in the most damaging manner possible.

Eris tolerates him when his ridicule divides her enemies and opposes him when his criticism reveals that one of her conflicts rests upon manufactured evidence.

The Blackwater Deeps – the third layer of Pandemonium

The Blackwater Deeps is a cold, water-worn layer of matte black stone.

Its caverns are narrower and wetter than those above. Streams flow across walls and ceilings according to local gravity. Stalactites, stalagmites and immense mineral curtains divide the darkness.

The rock absorbs light rather than reflecting it. Even magical illumination appears weak and isolated against its surfaces.

Water on Every Surface

The Blackwater Deeps begin where the carved passages of the Carved Lament descend into immense chambers containing cold, lightless lakes. Water gathers according to each cavern’s local gravity, forming separate bodies upon floors, walls, ceilings and curved shelves of stone.

A single chamber may contain several lakes facing one another across a central void. From one shore, travellers may see another lake hanging far above them, its waves moving across what appears to be the ceiling. Waterfalls can fall sideways, divide between competing gravity surfaces or curve through open space before striking distant stone.

The lakes vary greatly in size. Some fill narrow depressions between carved galleries. Others extend beyond the reach of light, concealing flooded shafts, drowned structures and passages leading into deeper cavern systems.

There is no universal water level. A route may climb away from one lake and emerge beneath another. A dry ledge can become a shoreline after a gravity change, while an exposed wall may begin shedding water into a newly opened shaft.

The Blackwater Deeps remain entirely enclosed within stone. There is no sky, natural horizon or surface world above the water. Even the largest lakes lie inside caverns whose distant walls are hidden by darkness.

Cold, Darkness and Sound

The Blackwater Deeps possess no natural light. Illumination reaches only a short distance across the black water, while the stone beyond remains concealed. Reflections upon several gravity surfaces can create the appearance of nearby shores, vessels or settlements that are actually far away.

The water is bitterly cold. Even sheltered lakes draw heat from unprotected travellers, and strong currents can carry swimmers away from the gravity surface upon which they entered. A creature pulled beyond one shore’s influence may fall through open cavern space towards another body of water.

Water muffles many of the cries carried down from the Carved Lament, but it transmits impacts, movement and low vibration across great distances. A splash may be detected from another shore long after its source has disappeared into darkness.

Wind continues to move through the layer. Broad lakes slow and redirect it, while narrow flooded passages can trap pressure until a sudden surge drives waves through tunnels or forces water from shafts without warning.

The apparent stillness of the Deeps is deceptive. A calm lake may conceal deep currents, flooded passages or creatures responding to vibrations too faint for travellers to notice.

Crossing the Black Lakes

Travel through the Blackwater Deeps requires movement between dry stone, submerged passages and separate gravity-bound lakes. A single route may involve climbing, swimming, boating and crossing exposed cavern voids.

Maps remain useful near stable shores, but they cannot easily represent overlapping water surfaces. Guides record which gravity face holds each lake, where its currents lead and how travellers can transfer safely between adjoining shores.

Directions often describe changes in water movement rather than fixed distances:

Follow the current until the ceiling lake passes overhead. Leave the water at the third carved pillar. Cross the dry wall before the returning wave reaches it.

Some routes depend upon temporary conditions. A flooded shaft may become passable only when pressure draws water away from its entrance. A stone bridge may remain accessible until a neighbouring lake spills across it. A passage that was dry during the outward journey may be submerged on the return.

A failed crossing usually leaves travellers displaced rather than immediately destroyed. They may emerge into an unfamiliar lake, lose equipment to a competing gravity field or reach a known ruin through a flooded entrance instead of the expected dry route.

Ropes, sealed containers, buoyant markers and several protected light sources are essential. Equipment secured only against falling may still be lost when water begins moving sideways or upward.

Flooded Shafts and Hidden Connections

Many lakes within the Blackwater Deeps connect through submerged shafts. Some descend into lower chambers, while others rise through walls or ceilings according to the local gravity.

A current disappearing beneath a stone shelf may enter another part of the same cavern. It may instead travel through miles of flooded passage before emerging in a lake with an entirely different orientation.

These concealed connections make water levels difficult to predict. A collapse in one cavern can drain a distant lake, flood a buried passage or release debris into a settlement that had no knowledge of the original disturbance.

Explorers test currents with marked floats, weighted lines and substances that can be recognised if they reappear elsewhere. Even a successfully charted connection can change after a pressure shift, collapse or obstruction.

Flooded shafts can provide direct routes through the layer, but they often remove the possibility of retreat. A strong current may carry travellers beyond the point from which they can swim back, forcing them to continue until the passage opens again.

Ruins Beneath the Water

Ruined structures stand beneath several of the Blackwater Deeps’ lakes. Their builders and original purpose remain unknown. Some resemble the worked stone of the Carved Lament, while others use forms and proportions not seen elsewhere in Pandemonium.

Columns rise from lake beds without reaching the shore. Doorways open beneath overhanging shelves. Stairs descend into deeper water, cross a wall and continue towards chambers buried beneath silt.

Some structures appear to have existed before their caverns flooded. Others contain channels, sealed chambers and pressure doors suggesting that water was always part of their intended environment.

Their condition varies according to the surrounding currents. Cold, still lakes can preserve carved surfaces, while stronger flows grind walls smooth or fill chambers with mineral deposits and debris carried from distant passages.

Air pockets survive within some sealed ruins. They may offer temporary shelter, but their air can be stale, poisonous or already claimed. Opening a sealed chamber can release trapped pressure, alter the surrounding water level or expose a dry interior to sudden flooding.

Salvage may include route records, sealed vessels, structural fittings and objects carried into Pandemonium through older portals. Removing such material can weaken a submerged structure or disturb something concealed within it.

Life in the Deeps

The Blackwater Deeps are sparsely inhabited, but they are not empty. Creatures adapted to cold water, complete darkness and shifting gravity move between lakes through submerged shafts and flooded galleries.

Some remain close to the stone, feeding upon mineral growths, carrion and matter carried down from the upper layers. Others move through open water and detect prey through pressure changes or vibration.

Predators rarely reveal their full size. Their presence may first appear as a current moving against the surrounding water, a trail of bubbles rising towards the wrong gravity surface or a shape passing briefly through reflected light.

The water complicates pursuit. A creature can move beneath a shoreline, cross into another gravity field or enter a submerged passage too narrow for an armoured traveller. A struggle that begins upon dry stone can become an underwater fight after a wave, collapse or failed crossing.

Howlers are less common here than in the Outer Howl and Carved Lament. Some packs hunt along dry galleries, shorelines and passages where vibration travels clearly through wet stone, but they avoid the largest flooded systems.

Refuge Along the Shores

Permanent refuge is rarer in the Blackwater Deeps than in the Outer Howl. A settlement requires stable dry chambers, protected access to water and routes that remain usable when nearby lakes rise or shift.

Some communities occupy ledges above known flood limits. Others survive within sealed ruins, suspended structures or chambers connected to several shores by ropes and enclosed passages.

Water is abundant but not automatically safe. Lakes may contain harmful minerals, decaying matter or contamination carried through unknown shafts. Reliable springs, condensation chambers and tested sections of larger lakes are therefore carefully guarded.

Boats and floating platforms are built for local conditions. A vessel designed for one gravity surface may become useless when a current carries it towards another. Many craft include anchor lines on several sides so they can attach to whichever surface becomes the new shore.

Visitors are expected to respect water stores, crossing lines and sealed doors. Damage to any of these can threaten an entire refuge long after the immediate incident has ended.

The Descent into the Sealed Dark

The transition towards the Sealed Dark begins where lakes become smaller, deeper and increasingly enclosed. Passages narrow around black water, while dry routes disappear behind collapsed stone and sealed barriers.

Currents weaken. The broad movement of the upper lakes gives way to isolated pools, submerged cracks and water trapped inside chambers with no visible outlet.

Sound diminishes with the wind. Waves no longer travel across immense caverns, and impacts return as short, heavy vibrations through nearby stone. The loss of distant noise makes every local movement more distinct.

Worked doors, blocked shafts and deliberately sealed passages become increasingly common. Some remain watertight. Others leak through narrow cracks, producing slow streams that vanish into darkness below.

Travellers enter the Sealed Dark when open lakes and navigable flooded routes give way to closed chambers, crushing confinement and passages whose original entrances have been buried or deliberately shut.

The Blackwater Deeps threaten through cold, depth and unseen movement. The Sealed Dark removes even the freedom of open water, enclosing travellers within the most remote stone of Pandemonium.

The Buried Tempest

The Buried Tempest is a migrating pressure system moving through the wet caverns.

Lightning travels through mineral veins. Cold rain is driven sideways across cavern walls. Pressure builds behind flooded tunnels before breaking through weakened passages.

The Tempest floods some routes while exposing others and never follows exactly the same course twice.

The Thunder Hollows

The Thunder Hollows contain enclosed storms that have persisted for generations.

Electrical discharges leap between wet mineral columns while pressure waves hammer the surrounding stone. Scavengers enter seeking charged crystal and condensed lightning.

Thunder magic, blasting powder and heavy construction are tightly controlled because a powerful sonic shock can destabilise the cavern.

The Sunken Vaults

The Sunken Vaults are immense chambers containing cold, lightless lakes.

Water clings to local gravity surfaces, producing lakes upon walls, ceilings and curved shelves. Some connect through flooded shafts to distant caverns.

Ruined structures stand beneath several lakes. Their builders and original purpose remain unknown.

The Drowned Galleries

The Drowned Galleries are tunnel networks periodically filled by pressure-driven floods.

A route may remain dry for months before black water surges through it without warning. Air pockets form beneath arches and within abandoned chambers, but their atmosphere may be stale or poisoned.

Salvagers enter during low-water cycles to recover tools, route records and the remains of lost expeditions.

The Curtains of Stone

The Curtains of Stone are immense mineral formations created by constant dripping.

Some are thin enough to ring like bells when struck. Others divide entire caverns into narrow chambers and concealed passages.

The wind produces deep tones as it passes between them. Changes in those tones warn of rising water or approaching collapse.

The Sealed Dark – the fourth layer of Pandemonium

The Sealed Dark is almost entirely solid stone.

It has no ordinary network of caverns or connecting tunnels. Isolated spherical pockets lie enclosed within an immeasurable mass of rock.

Some contain breathable air. Others hold poison, stale atmosphere, ash, freezing vapour or complete vacuum.

Many conceal beings, objects or ideas that powerful authorities were unwilling or unable to destroy.

The Sealed Dark is normally reached through portals, deliberate planar passage or magic capable of crossing solid stone. An ordinary traveller cannot walk there from the Blackwater Deeps.

The Last Descent

The Sealed Dark begins where the open lakes of the Blackwater Deeps contract into narrow flooded cracks, isolated pools and chambers buried behind immense masses of stone. Broad cavern space disappears. Passages become confined, steep and increasingly difficult to distinguish from natural fractures.

Water still reaches the layer, but it no longer dominates its geography. Thin streams emerge from sealed walls, gather in lightless hollows and vanish through fissures too narrow to follow. Some chambers contain deep pools without visible inlets or outlets, their surfaces remaining still even while distant stone trembles around them.

There is no single recognised entrance. Travellers descend through submerged shafts, collapsed stairs, drainage channels and openings exposed when water temporarily recedes. Many routes can be crossed in only one direction. A shaft that carries a party downward may later fill, collapse or become unreachable after a change in gravity.

The transition becomes unmistakable when the wind ceases to provide a continuous guide. Pandemonium’s roar remains present as pressure and vibration within the stone, but the open currents of the upper layers can no longer move freely through every chamber.

Closed Stone

The Sealed Dark consists of enclosed chambers divided by collapsed passages, fitted barriers and stone that appears to have been deliberately placed. Natural rock and worked construction overlap so completely that travellers cannot always determine whether a wall formed through pressure, collapse or design.

Some passages end beneath broken stone. Others terminate at smooth surfaces without seams, hinges or visible mechanisms. Doorways may be discovered only from one side, while stairways descend into walls whose adjoining chambers have been buried or removed.

Gravity complicates every structure. A door set into an apparent ceiling may once have opened onto the floor of another chamber. The collapse of a connecting passage can therefore leave an intact room only a few feet away and still completely inaccessible.

Not every barrier should be breached. A sealed wall may hold back water, unstable pressure, poisonous air or loose stone from a larger collapse. Opening a route can destroy the chamber from which the work begins.

Cracks, moisture, temperature and vibration offer clues about what lies beyond a barrier, but none provides certainty. Every wall conceals both a possible passage and a possible disaster.

Air, Pressure and Silence

Air is unevenly distributed throughout the Sealed Dark. Some chambers remain breathable because narrow fractures connect them to the upper layers. Others contain stale air, harmful vapours or no atmosphere capable of sustaining ordinary life.

A chamber that initially appears safe can deteriorate as flames and breathing creatures consume its remaining air. Secure rest therefore requires ventilation as well as shelter.

Pressure changes are equally dangerous. Opening a door or widening a crack may produce a violent inward pull, an outward burst or a slow movement of air that continues for hours. Dust, water and loose debris often reveal the change before travellers feel it.

The layer is quieter than the caverns above, but never truly silent. The winds of Pandemonium press against blocked passages, travel through hairline fractures and cause entire walls to groan beneath forces that cannot enter the chamber directly.

Sound carries only short distances through open air. Vibration travels much farther through the stone. A collapse, shifting body of water or repeated impact may be felt long before it becomes audible, although the source may lie in the next chamber or far across the layer.

Silence therefore offers no proof of safety. It means only that the immediate chamber has become isolated from the wider uproar.

Travel Through Buried Passages

Travel through the Sealed Dark depends upon finding, opening and preserving connections between enclosed spaces. Routes rarely remain broad enough for a group to move together. Travellers crawl through fractures, descend narrow shafts and pass equipment through openings before following it themselves.

Maps remain useful within connected chamber systems, but they become unreliable where passages collapse, flood or shift beyond reach. More valuable records describe the condition of barriers and the work required to cross them:

Pass the cracked door without touching its lower hinge. Follow the dry fissure until the air turns warm. Do not open the stone panel while the floor is trembling.

Progress often requires deliberate labour. Rubble must be moved, supports placed, water drained and narrow gaps widened. Such work consumes time, tools and breathable air while transmitting vibration through the surrounding stone.

A failed attempt usually changes the expedition’s choices rather than ending the journey immediately. A blocked route may force travellers towards an unknown chamber. A damaged support may require retreat. Opening the wrong barrier may release water while also revealing the only available escape.

Return is never guaranteed. Travellers must decide whether to reinforce a route behind them, leave it open for speed or seal it again to contain whatever lies beyond.

Chambers Without Entrances

The Sealed Dark contains chambers that have remained isolated for unknown periods. Some preserve abandoned camps, broken equipment and the remains of expeditions that reached them through routes no longer visible.

Others contain fitted stonework, carved supports and sealed interiors whose builders and purpose remain unknown. Their original entrances may lie behind collapsed walls, beneath flooded shafts or upon gravity surfaces no longer connected to the surrounding passages.

Dry chambers can preserve wood, cloth, writing and organic remains. Damp spaces become layered with mineral crusts, mould and deposits left by water moving slowly through the rock.

Opening an isolated chamber changes it. Fresh air may disturb pressure, weaken stone or cause fragile material to decay. Light can reveal a preserved interior while also announcing the breach to anything capable of detecting it.

Some chambers contain objects protected from the wider plane. Others appear to have been sealed to protect the wider plane from what remains inside. The difference may become clear only after the barrier has been broken.

The Deepest Known Layer

The Sealed Dark is the fourth and deepest confirmed layer of Pandemonium. No single chamber forms its centre, and no recognised boundary marks an end to the plane.

Some passages descend until they become too narrow to follow. Others end at barriers through which wind, water or vibration can still be detected. These signs suggest further spaces beyond the known chambers without proving that another layer exists.

Expeditions seeking a final depth find only increasing isolation. Connected routes become rarer, breathable chambers less dependable and every opened barrier creates new uncertainty about what pressure it contained.

The danger of the Sealed Dark lies in confinement rather than emptiness. Stone holds back water, wind, sound and movement from the rest of Pandemonium. Survival depends upon deciding which boundaries must be opened and which must remain intact.

Here the plane’s uproar has not vanished. It waits beyond every sealed wall, pressing against the chamber and searching for an opening.

The Breathless Pockets

The Breathless Pockets contain atmospheres incapable of supporting ordinary life.

One may hold poison, ash, spores or freezing vapour. Another may contain no atmosphere at all.

Some preserve bodies, libraries, battlefields or crime scenes almost perfectly. Opening them may immediately begin destroying what they preserved.

The Closed Chamber

The Closed Chamber is a network of immense stone doors discovered within separate pockets.

The doors possess different designs and mechanisms, yet appear connected to the same hidden structure.

Some open into small cells. Others reveal palaces, tombs, battlefields or spaces too large to fit within the surrounding pocket.

Some prisoners were confined under recognised judgement. Others were hidden because their testimony, knowledge or existence threatened a ruler or divine power.

The Last Anchorage

The Last Anchorage occupies a single breathable pocket within the Sealed Dark. Its only entrance is a guarded portal opening into a fortified receiving chamber.

Its inhabitants shelter refugees, wounded travellers and people pursued by creatures that hunt through sound. Names are written rather than spoken. Alarms use light and vibration, and disputes are heard inside insulated chambers.

An ancient planar anchor holds the portal to a fixed destination in the Outer Howl. The gate is opened only for controlled arrivals and departures. If the anchor fails, the portal will drift or close, leaving the settlement completely isolated.

Divine Powers and Exiles

No single divine power is recognised as sovereign over Pandemonium.

The concealed chambers, difficult approaches and unreliable communications attract exiles, fugitive prophets, imprisoned heralds and powers seeking neutral or hidden ground.

Divine Power	Relationship to Pandemonium
Eris	Ruler of Strife, a limited divine enclave within the Carved Lament
Momus	Occasional exile and independent critic with no permanent realm
Eshu	Occasional visitor at unstable crossings and disputed routes

A deity may establish a sanctuary or temporary court, but its authority extends only through its wards, servants, agreements and defended territory.

Wind and storm portfolios alone establish no connection with the plane. Pandemonium’s winds are conceptual uproar trapped within stone rather than weather governed beneath an open sky.

Inhabitants

Petitioners of Pandemonium

The plane draws souls whose pursuit of freedom became confusion, abandonment or harm.

They include people who treated every obligation as oppression, abandoned companions whenever responsibility became inconvenient, used confusion to control others or demanded independence while forcing others to carry its cost.

Petitioners retain recognisable personalities, memories and relationships. Some repeat their former conduct. Others recognise its consequences and seek refuge within communities founded upon chosen responsibility.

A petitioner remains a person. Family, surrender, sanctuary, recognised status and local law continue to matter.

The Unmoored

The Unmoored reject permanent refuge membership and travel alone or in temporary groups.

Some are skilled wanderers who respect the safety of others. Some sabotage route marks, reject rescue protocols or resent communities whose survival requires cooperation.

Several Havens maintain procedures for offering aid without allowing one person’s refusal of safety to endanger an entire rescue party.

Howlers — Signature Predators

Howlers are rare native outsiders adapted to complete darkness, violent winds and shattered acoustics.

They hunt primarily within the Outer Howl and Carved Lament. Packs coordinate through stone vibration, pressure pulses, scent, posture and resonant calls pitched beneath the surrounding wind.

Howlers are signature predators rather than common animals. A single pack may control many miles of connected cavern.

Individual Howlers differ in language, custom and conduct. Some behave as territorial predators. Others negotiate, observe boundaries, accept surrender or maintain lasting agreements.

Recognition and legal consequence depend upon the individual or pack encountered rather than species alone.

Isolated Communities

Permanent settlements are rare.

Most are fortified refuges, family shelters, salvage stations or isolated Haven districts rather than cities. They survive through anchor maintenance, fungus farming, condensation collection, salvage, guide services and portal trade.

Common communication systems include:

• Speech within protected chambers
• Hand signs during heavy wind
• Touch-signals in darkness
• Light codes across large caverns
• Written instructions in echo-haunted regions

Some refuges protect broad personal autonomy while imposing temporary emergency duties. Others exploit genuine danger to justify permanent domination.

Exiles, Migrants and Fugitives

Pandemonium shelters political refugees, escaped prisoners, abandoned servants, oath-breakers, hunted witnesses and people whose former homes have no place for them.

Exile establishes neither innocence nor guilt. Pursuers may represent lawful authority, private vengeance or powers attempting to silence dangerous knowledge.

Air-born beings enter through breaches formed after the Elemental Plane of Air. They remain local migrants rather than the plane’s native population.

Bestiary Relationships

Creature	Relationship	Primary Use
Howler	Rare native outsider	Signature pack predator of the Outer Howl and Carved Lament
Cloaker	Rare established cavern resident or migrant	Intelligent sonic ambusher, territorial neighbour or flock leader
Cave Fisher	Transplanted underground predator	Ambusher above ledges, bridges, shafts and underground rivers
Air Elemental	Later migrant from Elemental Air	Displaced intelligence, unwilling power source, guide or uncontrolled current
Aerial Servant	Summoned or stranded Air-born visitor	Invisible tracker following an old command through the labyrinth

Demons may enter from the Abyss as fugitives, hunters or invaders, but they do not form the plane’s native ecology.

Other subterranean creatures may arrive through portals or deliberate introduction. Their presence should have a specific route, history and ecological consequence rather than being assumed from cavern terrain alone.

Personhood, Law and Consequence

Pandemonium has no universal government, but inhabited refuges maintain law, authority and recognised status.

Personhood depends upon intelligence, conduct, custom, treaty, kinship and recognition rather than appearance or creature type.

Common legal concerns include:

• Anchor Damage: Sabotaging an occupied structure endangers everyone attached to it.
• Shelter Theft: Seizing protected space during a storm can amount to attempted killing.
• Air and Water Rights: Breathable pockets, cisterns and condensation systems are protected communal resources.
• False Signals: Forged warnings and rescue calls can cause mass casualties.
• Name Misuse: Selling or broadcasting a protected name may expose its owner to imitation or hostile magic.
• Pressure Trespass: Opening a door or cutting a passage can alter the safety of an entire refuge.
• Shared-Line Duty: Travellers may be required to assist recognised people attached to the same anchor line.
• Concealed Risk: Hiding structural or atmospheric danger from those likely to suffer it is serious wrongdoing.
• Abandonment: Deliberately cutting away a dependent person without immediate necessity may be prosecuted.

Surrender has force where recognised people and authorities are involved. Haven guards, organised exiles, intelligent outsiders and recognised Howler packs may accept it under local conditions.

Terms may include disarmament, temporary restraint, compensation, service, withdrawal or removal from a protected refuge.

Storms, rockfalls, unintelligent predators and uncontrolled elemental events do not recognise surrender.

Wrongful killing can lead to compensation, vendetta, exile, denial of shelter or prosecution under the law of a recognised Haven.

Pandemonium and the Mortal World

Gates most often appear in deep mines, wind-filled cave systems, abandoned underground fortifications and sealed chambers uncovered through excavation.

A breach may first reveal itself through pressure changes, lamps extinguishing inside enclosed rooms, voices returning from impossible directions or a shaft producing wind despite having no known opening.

Most authorities interpret these signs as mine instability, trapped air or haunting. Experienced planar travellers recognise that a true breach alters sound and pressure before opening fully.

Permanent gates are rare. Opening one can connect a mortal cave system to the pressure of the Outer Howl, flood tunnels with water from the Blackwater Deeps or expose a forgotten prison within the Sealed Dark.

In the mortal world, miners, masons, castle engineers and underground communities may encounter a breach before any scholar or magician understands what has opened.

Travel and Arrival

Arrival in Pandemonium

Most gates deliver travellers into exposed locations.

A party may appear upon a narrow shelf in the Outer Howl, inside a screaming carved tunnel in the Carved Lament, beside black water in the Blackwater Deeps or within a sealed pocket whose air is failing.

A portal may collapse after passage, while pressure pulls unsecured possessions back through the opening.

New arrivals should secure the group, identify the active gravity surface, protect their hearing and establish silent communication before exploring.

Essential Equipment

• Independent ropes and harnesses
• Pitons, hooks, chains, spikes and repair tools
• Effective hearing protection
• Eye, mouth and face protection
• Enclosed lights and backup illumination
• Portable wind barriers
• Sealed food and water
• Written route instructions
• Silent communication methods
• A separation procedure
• A password or physical identity signal
• An agreement covering rescue obligations and when an anchor line may be cut

Navigation

The plane possesses no universal north, downward direction or surface reference.

Guides navigate through airflow, pressure, mineral texture, echo delay, gravity transitions, moisture and maintained route marks.

Follow the warm current until the stone begins to hum. Cross to the opposite gravity face after the third pressure lull. Take the carved fissure and ignore every voice calling from below.

A copied map without route instructions may provide little help. Long journeys depend upon shelters, warnings and knowledge maintained by previous travellers.

Portals

Stable portals commonly resemble:

• Cave mouths blowing against local weather
• Mine shafts whose echoes return incorrectly
• Cracked bells sounding without being struck
• Stone doors uncovered behind collapsed walls
• Whistling fissures in mountains or cellars
• Storm-damaged summoning circles
• Passages that lengthen with each entry

Airflow through a portal can reveal conditions beyond it. A sudden reversal may indicate a collapse, pressure surge or deliberate sealing on the far side.

Pockets within the Sealed Dark are normally reached by portals rather than ordinary passages.

Mechanics

Running Pandemonium

Uproar First, Alienation Second

Noise, disorder, confusion and turmoil are the plane’s immediate identity.

Alienation is their consequence. Winds break communication, contradictory signals divide groups and unrestricted movement leaves travellers without dependable direction.

Keep the Layers Distinct

• The Outer Howl: Exposed movement, uncertain crossings, rare Havens and Howler territory
• The Carved Lament: False voices, worked passages, acoustic investigation and Strife
• The Blackwater Deeps: Darkness, floods, cold water, slippery stone and submerged ruins
• The Sealed Dark: Finite air, isolated environments, cosmic anchors and forgotten prisoners

Preserve Player Agency

False voices should create uncertainty without forcing characters to follow them. Wind should threaten lines and equipment without making separation unavoidable.

Preparation, relationships, investigation and magic should change the available choices.

Keep Failure Playable

A failed check should alter the situation rather than end the expedition.

Failure can cost time, supplies, hearing, secrecy, political trust or access to a safe route. It may separate characters while leaving each with meaningful decisions.

Make Magic a Trade-Off

• Flight crosses a shaft but becomes dangerous in violent wind.
• Silence defeats voice imitation but conceals warnings.
• Thunder harms enemies but may destabilise stone.
• Teleportation bypasses distance but may arrive within an exposed gravity field or sealed pocket.
• Wall magic creates shelter but may redirect pressure toward another refuge.
• Light reveals hazards but attracts attention across vast caverns.

A chain can imprison. A rope can also prevent a companion from falling into darkness.

Play-Pressure Test

1. Arrival: The party appears upon an exposed shelf and must secure itself before colliding winds strike.
2. Predator: Howlers begin coordinating through stone vibration while remaining unseen.
3. Crossing: Eshu offers several routes described through exact but easily misunderstood conditions.
4. Refuge: Haven guards offer sanctuary in exchange for repairing a damaged anchor.
5. Carved Lament: A missing companion’s voice calls from several passages at once.
6. Strife: Eris offers safe passage in exchange for revealing a damaging truth about an ally.
7. Sealed Dark: The party finds a prisoner whose sentence may have ended centuries ago.
8. Consequence: The group’s choices determine casualties, future sanctuary and whether the prison remains sealed.

Adventure Hooks in Pandemonium

The Haven That Cut Its Anchor

A Hanging Haven tears free from its supports and begins drifting toward a cavern wall. Its rulers blame newly arrived refugees, while the refugees claim the failure was arranged to destroy evidence of an earlier abandonment.

The Apple No One Claims

A golden apple appears within a Haven bearing the words “To the One Who Saved Us.” Three leaders claim the title while Eris ensures that each receives evidence against the others.

The Prisoner Whose Sentence Ended

A divine herald sealed within the Sealed Dark claims that its sentence expired centuries ago. The authority that passed judgement has vanished, leaving nobody recognised as able to confirm or end the punishment.

Frequently Asked Questions

What does Pandemonium represent?

Pandemonium represents wild and noisy disorder, confused motion and broken communication. Its uproar produces alienation when freedom loses direction, responsibility and fellowship.

What are its four layers?

The four layers are the Outer Howl, the Carved Lament, the Blackwater Deeps and the Sealed Dark.

When does the plane form?

It forms during Eon VII, when enduring concepts and moral forces crystallise into the Outer Planes.

Do its winds come from Elemental Air?

No. The winds form with Pandemonium and predate Elemental Air. Later breaches allow Air-born creatures to enter the labyrinth.

Who rules Pandemonium?

No single power rules the whole plane. Eris controls Strife, a limited enclave within the Carved Lament.

Are Howlers native?

Yes. Howlers are rare native outsiders and signature pack predators of the Outer Howl and Carved Lament.

Is it a prison plane?

It contains many prisons, especially within the Sealed Dark, but its wider identity is uproar, confusion and alienation rather than captivity alone.

How does it differ from Carceri?

Carceri embodies imprisonment and betrayal. Pandemonium embodies disorder, failed communication and movement that never becomes escape.

How does gravity work?

Gravity pulls away from the open centre of each cavern and toward the surrounding stone. Travellers can stand upon the floor, walls and ceiling of the same chamber.

Can magical silence stop the winds?

Magical silence suppresses sound while leaving physical wind, pressure and airborne debris unchanged.

Mythic and Historic Context

The name Pandemonium enters English literature through John Milton’s Paradise Lost, first published in 1667. Milton uses Pandæmonium as the immense capital where the infernal host gathers for council.

The complete poem can be read through Project Gutenberg. The Milton Reading Room at Dartmouth provides an annotated version of Book I.

In later English, pandemonium comes to mean wild and noisy disorder, confusion, turmoil and uproar. The plane makes that meaning physical through colliding winds, contradictory signals and voices travelling without dependable understanding.

Alienated chaos grows from that immediate meaning. The plane begins as overwhelming disorder. Alienation is what prolonged disorder does to people who can no longer communicate, trust directions or rely upon one another.

The winds also draw inspiration from real cave airflow. Differences between internal and external pressure can force strong currents through restricted cave entrances and passages.

The United States National Park Service explains this effect in What Causes the Wind of Wind Cave? and its Wind Cave geology resources.

Within Pandemonium, that natural principle becomes cosmic. Every connected cavern belongs to an immeasurable pressure system. A distant opened door can alter the wind across refuges whose inhabitants never see who opened it.

The Carved Lament draws upon the ancient association between caves, altered voices, prophecy and the unseen. Real caverns change the direction, timing and tone of sound. Here, some echoes remain natural while others become witnesses, memories or hunting tools.

The Blackwater Deeps develops water erosion, underground rivers and mineral deposition into a subterranean world where light, direction and dry ground become uncertain.

The Sealed Dark transforms the sealed chamber into a cosmic principle: isolated spaces hidden inside solid stone, preserving prisoners, secrets and abandoned judgements beyond ordinary travel.
