Overview

Arborea is the plane of passionate freedom.

Its forests rise higher than mortal towers. Its mountains carry divine halls above the storms. Its seas answer songs sung on distant shores. Vineyards preserve memories within their fruit, flowers open when beloved names are spoken and valleys change colour as their people celebrate or mourn.

Everything in Arborea feels intensely alive.

Joy becomes festival. Grief becomes rain. Love becomes shelter. Anger becomes thunder. Inspiration shines as visible light. Memory takes root in orchards, statues and songs. Courage opens passages through mountains, while shame, jealousy and possessiveness may close them again.

The plane welcomes powerful emotion, but passion gains worth through what it creates, protects and allows others to become.

A ruler may command respect, but title alone cannot compel loyalty. A host may protect a guest, but cannot turn hospitality into captivity. Lovers may promise devotion, but neither may claim ownership of the other. A poet may rebuke a god when the poem carries truth. A hero may reject a divine command and remain honourable.

Arborea is beautiful, generous and dangerous. Its greatest perils are celebration without rest, love turned possessive, grief preserved as a weapon, anger emptied of mercy, memory rewritten for power and beauty treated as something to own.

The Nature of Arborea

Arborea stands between the Beastlands and Ysgard within the Upper Outer Planes.

The Beastlands expresses freedom through instinct, wilderness, migration and the life of animals. Ysgard expresses freedom through courage, struggle, contest and heroic defiance. Arborea expresses freedom through feeling, relationship, art, celebration, remembrance and the power to become someone new.

Its chaos is living choice.

Communities form around friendships, sacred duties, artistic movements, shared grief and common causes. People remain because they choose to remain. Settlements divide when their purposes diverge, reunite when old injuries are answered and transform themselves without waiting for distant permission.

Its goodness is active. Arborea resists slavery, magical domination, humiliation, historical erasure and pleasure founded upon another person’s suffering. It honours hospitality, generosity and protection while demanding that these virtues remain freely given.

Anger, rivalry, sorrow, desire, pride and longing all have a place here. The plane judges them by what follows.

Planar Laws

Emotion Shapes the World

Strong and honestly recognised emotions alter local weather, colour, vegetation, music and terrain.

A reconciliation may cause a dead orchard to flower. Suppressed grief may gather as a storm that cannot break. A community preparing for rebellion may hear drums beneath the earth. A feast founded upon genuine welcome may cause tables to fill no matter how many guests arrive.

False displays produce weaker and shorter-lived effects. Arborea answers most strongly when emotion is genuine and carries consequences.

Hospitality Carries Power

A host who welcomes a willing guest gains supernatural authority to protect that guest from violence, intrusion and betrayal.

Guest-right weakens when the host conceals a dangerous condition, demands obedience as payment or prevents the guest from departing. A guest who knowingly betrays generous hospitality may find every door in the region closed against them.

Art Reveals Truth

Songs, plays, sculptures, dances and stories may expose realities concealed by ordinary speech.

A performance might reveal the emotional cost of an ancient victory, give form to communal grief or allow witnesses to experience an event through another person’s eyes. Art does not establish every disputed detail, but it makes wilful denial far harder to maintain.

Promises Bind; People Remain Free

Freely sworn oaths possess real force in Arborea. Friendship, marriage, service, kinship and loyalty can create profound obligations.

Those bonds preserve the will and personhood of everyone involved. An oath extracted through fear carries little authority, while a humble promise freely kept may reshape an entire region.

Grief Must Be Allowed to Move

Arborea protects mourning and allows sorrow to be expressed openly.

Grief becomes dangerous when deliberately trapped, exploited or denied. Unanswered mourning gathers in dreams, storms, songs and the landscape until someone gives it honest expression.

Celebration Requires Willing Participants

Feasts, dances, athletic games, dramas and ecstatic rites are common throughout the plane. Participation remains a choice.

A revel that prevents its guests from resting or departing ceases to embody Arborean celebration and begins to corrupt the surrounding region.

Beauty Creates Responsibility

Beauty can heal, inspire and reveal possibility. It can also provoke vanity, obsession and possessiveness.

Those who protect beautiful places while allowing them to remain alive and changing earn Arborea’s favour. Those who destroy or imprison others in order to possess beauty find splendour fading from everything they touch.

Memory Cannot Be Owned

Memories may be shared, performed, preserved or entrusted to another person. They carry the personhood, history and responsibilities of those who lived them.

Pelion reacts strongly to historical erasure. Names removed to conceal wrongdoing reappear in stone, water or dreams. False monuments crack. Suppressed witnesses return through song, theatre and inherited memory.

The Three Layers of Arborea

Arborea consists of three immeasurable layers joined through divine gates, sacred rivers, living currents, emotional storms, ancient performances and acts of mythic significance.

• The Olympian Glades: Living passion, chosen community, artistic achievement, divine splendour and the present Olympian order.
• Ossa: Movement, transformation, voyage, separation, oceanic song and meaningful return.
• Pelion: The surviving inheritance of the Titan Age, where elder communities, sacred memory and unfinished history remain active.

Campaign division: the Olympian Glades embody the present Olympian order; Ossa embodies the living and changing sea; Pelion preserves the Titan-age civilisation that survived. Othrys and the deeper Tartarean regions of Carceri hold exiled, condemned and imprisoned powers.

The Olympian Glades

Arborea’s first layer is a vast realm of immense forests, flowering valleys, sacred rivers, storm-crowned mountains, orchards, vineyards, open-air theatres and divine estates. It is the most heavily inhabited and socially active of Arborea’s three layers, with communities formed around freely chosen bonds, shared traditions, artistic movements and sacred duties.

Gods receive petitioners upon mountain summits and within divine halls. Poets challenge rulers in public theatres. Athletes compete for honour in gymnasia and festival grounds. Travelling celebrations cross entire valleys, carrying music, drama, debate and feasting between settlements.

Arguments may be fierce, but authority carries less weight here than courage, truth, hospitality and loyalty that has been earned.

The principal regions of the Olympian Glades are:

• Mount Olympus: The divine summit and principal realm of the Hellenic gods.
• The Laureled Valleys: Olive groves, vineyards, gymnasia, feasting grounds and athletic or artistic contests.
• The Wild Choir: An immense living forest where birds, rivers, leaves, nymphs and musicians form one evolving song.
• The Thunder Vineyards: Storm-fed vineyards whose wines preserve courage, grief, longing and other emotions present during the harvest.
• The Theatre of First Stories: A sacred amphitheatre where performances reveal forgotten witnesses and transform how old events are understood.
• The Valley of Honest Grief: A green valley of warm rain where the living and the dead mourn without judgement or forced consolation.

Typical inhabitants include petitioners, dryads, nymphs, satyrs, centaurs, celestial spirits, pegasi, sacred animals and divine attendants.

Mount Olympus

Mount Olympus rises above the Olympian Glades as a divine summit and gathering place of the Hellenic gods.

The earthly mountain in Greece is a Material Plane anchor. Sacred paths, divine invitation and exceptional mythic deeds may lead from that mountain to the planar summit, but an ordinary ascent remains within the mortal world.

Zeus, Hera, Athena and Themis are among the powers associated with the divine summit. The wider Olympian pantheon maintains halls, gardens, workshops, shrines, embassies and visiting places according to divine office, kinship and recognised realm.

Mount Olympus is one divine realm within Arborea and the political heart of the Olympian order.

The Laureled Valleys

Vineyards, olive groves, orchards, gymnasia and public feasting grounds fill these broad valleys.

Competitions include racing, wrestling, poetry, music, debate, sculpture, dance and acts of hospitality. Victory brings honour, but victors are expected to enrich the community rather than merely humiliate the defeated.

Rival settlements sometimes allow artistic or athletic competition to harden into inherited hatred. The landscape then magnifies the feud until someone finds the courage to break it.

The Wild Choir

Every living thing in this enormous forest contributes to its music.

Birdsong forms melody. Rivers provide rhythm. Leaves answer spoken verse. Dryads, nymphs, satyrs, centaurs and travelling musicians tend its harmonies and search for songs that have never before been heard.

A missing voice may reveal disease, captivity, desecration or an old wrong concealed beneath the roots.

The Thunder Vineyards

These vineyards spread across mountain slopes watered by warm rain and frequent storms. Their terraces, groves, wine caves, theatres and open-air feasting grounds form one of the principal Arborean estates of Dionysus, god of wine, vegetation, theatre, revelry, wildness and sacred madness.

Dionysus moves freely through the vineyards rather than ruling from a single permanent palace. His arrival is announced by disembodied laughter, sudden music, rapid vine growth, wandering wild animals and the scent of crushed grapes upon the wind. His court may gather around an ancient wine press, a storm-lit pavilion or a theatre raised overnight from flowering vines.

His travelling retinue includes maenads, satyrs, Seilenoi, nymphs, centaurs, musicians, actors, vintners and sacred lions or panthers. Silenus often accompanies the god as his old tutor, counsellor, storyteller and drunken prophet. The Muses attend important performances and carry newly inspired songs between the vineyards, Mount Olympus and the Theatre of First Stories.

The vineyards remain home to independent households, petitioners and vintners who do not serve Dionysus directly. The god protects their right to cultivate their own vines, preserve their own traditions and refuse entry to any revel that does not respect their hospitality.

Each vintage preserves an emotion present during its harvest. One wine may restore the courage of a fallen defender. Another may carry the longing of people divided by war. A celebratory vintage may preserve laughter for centuries, while grapes harvested during betrayal, panic or suppressed grief can produce wine filled with obsession, fury or despair.

Dionysian festivals bring music, theatre, feasting, dance and transformation to the slopes. Willing participants may cast aside fear, shame and imposed roles, discovering truths they lacked the courage to face while sober. The greatest revels leave their guests more fully themselves rather than stripped of memory, judgement or freedom.

Maenads and other ecstatic attendants may become dangerous when sacred frenzy overwhelms judgement. A revel that compels participation, prevents rest or refuses to let its guests depart violates Arborea’s law of freely chosen celebration. Storms gather above the offending festival, the wine turns bitter and the memories stored within every neighbouring vine begin to testify against those responsible.

The finest vintners treat emotional memory as a sacred responsibility. Dionysus favours those who use wine to reveal truth, inspire art, strengthen fellowship or release honest feeling. Those who bottle another person’s grief, courage or desire as a means of control risk awakening the destructive aspect of the god and the wrath of his retinue.

The Theatre of First Stories

A vast amphitheatre stands within a natural bowl of white stone.

Performances here can transform how an event is understood, though they cannot change what physically occurred. A celebrated hero may be made to confront the cost of victory. A forgotten witness may finally be heard. A hated enemy may be revealed as something more complicated than the story preserved by the victors.

Several unfinished plays continue to influence mortal dreams.

The Valley of Honest Grief

Warm rain falls across this green valley, nourishing white flowers, dark-leaved trees and clear streams that carry sorrow gently through the Olympian Glades.

The living and the dead come here to mourn. Arborean petitioners remember their mortal lives, companions who passed into other divine realms, families divided by death and losses that followed them beyond the grave.

Some mourn the people they once were. Others grieve old failures, broken communities or loved ones whose final fate remains unknown.

Living visitors may meet the dead who dwell in Arborea, provided those petitioners freely choose the meeting. The valley honours the actual dead who reside here and the memories carried by those who mourn.

Memory appears throughout the landscape as familiar scents, distant voices, flowers growing in beloved colours and brief figures glimpsed through the rain. These manifestations express what the mourner carries.

The valley offers recognition. Sorrow may remain for as long as it is honestly felt, but it gradually becomes something that can be carried without consuming the mourner.

Those who steal memories, silence grief, impersonate the dead or turn another person’s mourning into a weapon awaken violent storms. The rain becomes cold, the streams rise and every stolen sorrow returns to its thief.

Ossa — The Living Sea

Arborea’s second layer is an immeasurable ocean beneath rapidly changing skies. Its waters shift between blue, green, violet and wine-dark black, while islands rise and disappear in response to emotion, memory and storm.

Coral forests support cities beneath the waves, great singers carry messages across impossible distances and powerful conflicts gather as tempests capable of disturbing the entire layer.

Ossa expresses freedom through movement, transformation, voyage, departure and return. Its peoples are shaped less by fixed borders than by currents, migrations, songs, storms and the responsibilities carried between distant shores.

Settlements may drift, submerge, surface or grow from living reef. Travellers are judged not only by where they are going, but by what they refuse to leave behind.

The principal regions of Ossa are:

• Aegae — The Golden Palace Beneath the Sea: Poseidon’s principal Arborean court, an imperishable golden palace surrounded by divine stables, submarine halls and waters calmed or broken by the will of the Earthshaker.
• The Wine-Dark Expanse: The open ocean, crossed by celestial vessels, living islands and travelling sea communities.
• The Isles of Sudden Weather: Islands formed where powerful emotions meet the sea, some lasting hours and others surviving for generations.
• The Coral Revels: Living reefs containing submerged halls, gardens, festivals, councils and theatres.
• The Singing Deeps: Deep coral forests where sea spirits and immense creatures preserve songs capable of crossing planar boundaries.
• The Drowned Amphitheatres: Ruined theatres upon the sea floor whose performances continue without visible actors.
• The Shore That Remembers: An endless coastline where every departure leaves a trail until the traveller returns, reaches a true destination or abandons the purpose of the journey.

Typical inhabitants include aquatic petitioners, nereids, ichthyocentaurs, celestial sea creatures, sacred dolphins, great singers, reef-dwellers and other recognised sea peoples.

Aegae — The Golden Palace Beneath the Sea

Far beneath Ossa’s wine-dark waters stands Aegae, the principal Arborean court of Poseidon. Its golden halls, marble terraces and immense colonnades remain bright beneath the sea, untouched by pressure, darkness or age.

The palace does not occupy one fixed position upon an ordinary map. It appears where Poseidon’s authority, anger or hospitality gathers most strongly. Mariners may glimpse its towers below a suddenly calm sea, while aquatic travellers may reach it by following the sound of bronze hooves across the ocean floor.

Amphitrite shares the court as queen of the sea. Tritons, nereids, hippocampi, sacred dolphins, sea-horses, heralds and divine attendants maintain its halls, receive ambassadors and carry commands throughout Ossa.

Its most famous precinct is the Stable of the Brazen Hooves, where hippocampi stand beneath vaulted roofs of pearl, white stone and gold. These divine sea-horses possess the forequarters of magnificent horses and long, powerful bodies adapted to the deepest waters of Ossa.

The greatest among them have bronze-bright hooves, streaming manes and scales that shine like sunlight beneath the sea. They draw Poseidon’s chariots through the water at impossible speed, leaving a road of calm water behind them and never wetting the divine axle.

When the hippocampi are harnessed, every creature in the surrounding sea feels the approach of the Earthshaker. Currents tighten, distant reefs tremble and storm-light passes through the water above Aegae.

The Hall of Tides contains a living map of Ossa formed from currents, foam and drifting light. It shows recognised sea roads, migrating islands, storms, drowned cities and waters that have rejected Poseidon’s authority. The map changes whenever a voyage begins with sufficient courage, desperation or divine importance.

The Trident Court receives gods, petitioners, sea peoples, mortal envoys and rulers seeking protection or judgement. Poseidon’s decisions are swift and powerful, but Ossa’s independent communities may challenge them through treaty, guest-right, ancient kinship or appeal to an older sea power.

Aegae is one of Poseidon’s principal divine seats. He also retains an Olympian hall upon Mount Olympus and a greater elemental dominion connected to the Elemental Plane of Water.

Poseidon’s presence transforms the surrounding sea. Friendly ships find clear passages and favourable currents. Hostile fleets encounter rising reefs, broken compasses and waves that turn them away. When the god is angered, the palace gates close, the divine horses stamp within their stables and earthquakes pass through distant coasts.

The Wine-Dark Expanse

Open water stretches beyond every horizon.

The sea favours travellers who have honestly accepted the purpose of their journey. Those fleeing truths they refuse to face encounter contrary currents, repeating horizons and storms born from their own denial.

Celestial vessels, living islands and travelling sea communities cross the Expanse without always seeking land.

The Isles of Sudden Weather

These islands form wherever powerful emotion meets the sea.

A joyful reunion may raise an island covered in flowers. Betrayal may create black cliffs beneath permanent lightning. Some islands last only a few hours, while others survive long enough to develop peoples, traditions and histories.

An island’s inhabitants retain their personhood and community even after the emotion that first raised their home has faded.

The Coral Revels

Immense living reefs support submerged halls, gardens, theatres and gathering places.

Nereids, ichthyocentaurs and other sea peoples hold festivals, councils and competitions here. Music travels through the water as colour, pressure and vibration.

The Revels become dangerous when hosts use beauty, enchantment or intoxicating food to prevent guests from leaving.

The Singing Deeps

The deepest waters contain pale coral forests, lightless trenches and enormous, slow-moving creatures whose songs cross planar boundaries.

Deep singer whales are among the greatest custodians of these waters. These intelligent, midnight-blue whales preserve oceanic wisdom within haunting harmonies that can calm violence, carry messages across impossible distances and awaken memories thought lost.

Most travel alone, though rare pods gather when a song is too ancient or powerful for one voice to carry. Dolphins, tritons, merfolk and other benevolent sea peoples often accompany them as students, messengers and trusted companions.

Sea spirits preserve ancient melodies among the coral forests. Some songs carry warnings from drowned cultures. Others recount forgotten voyages, reveal changes in distant seas or call particular travellers by names they have never heard.

Some inhabitants of Ossa believe the deep singers found in mortal oceans are young celestial whales, or temporary avatars sent into the Material Plane to gather knowledge before returning to the Outer Planes.

When one of the great singers falls silent, the loss reaches far beyond its trench. Currents alter, migrations fail, messages vanish and fragments of oceanic history may disappear from every living memory in Ossa.

The Drowned Amphitheatres

Ruined theatres stand upon the sea floor.

Their performances continue without visible actors. Sailors hear tragedies through the hulls of ships, while divers see processions moving beneath clear water.

Several plays end differently depending upon who watches them. One missing final performance may explain why a drowned city has never returned to the surface.

The Shore That Remembers

Every departure leaves a mark upon this endless coastline.

Footprints remain until the traveller willingly returns, reaches the destination they truly sought or abandons the purpose of the journey. The shore contains tracks belonging to gods, exiles, missing heroes and entire migrating peoples.

Every trail moves towards the sea. The footprints stop at the precise point where the traveller entered the water, and no mark continues beneath the waves.

Following a trail reveals moments from the traveller’s departure, but does not necessarily show where the traveller is now.

Pelion — The White Silence

Arborea’s third layer is the surviving realm of the Titan Age: a vast white land of pale mountains, monumental cities, buried courts, sacred orchards, observatories and elder divine estates.

The Titanomachy ended the Titans’ supremacy, but Pelion preserved communities, households, sanctuaries and works that survived the war. Some elder powers remained outside the Tartarean prisons through neutrality, reconciliation, divided allegiance, inherited duty or a fate separate from the condemned.

Other cities stand abandoned because their rulers were killed, exiled or imprisoned. The realm of Othrys in Carceri contains exiled Titans and banished gods, while Cronus remains imprisoned in Tartarus.

Pelion holds the elder civilisation that continued outside those prisons.

The layer is quiet because its spaces are immense and its population is scattered. Life gathers around surviving estates, hidden cities, sacred groves, sealed valleys and ancient workshops.

Elder households maintain gardens beneath the dust. Petitioners preserve ancient crafts. Dactyls work in sealed forges. Ash-tree nymphs guard sacred groves. Primordial cyclopes repair structures whose first purposes belong to the age before Olympian rule.

Pelion expresses freedom through remembrance: the freedom of people, gods and communities to survive the fall of an old order without surrendering every part of their identity.

The principal regions of Pelion are:

• The White Expanse: Open country between surviving elder estates, abandoned monuments and half-buried cities.
• The Buried Cities: Former centres of Titan rule, some inhabited and others sealed since the Titanomachy.
• The Avenue of Nameless Statues: A ceremonial road whose erased figures preserve rulers, allies and witnesses removed from official history.
• The Last Amphitheatre: A monumental theatre containing an unfinished account of the war between Titans and Olympians.
• The Orchard Beneath the Dust: A hidden valley whose fruit preserves memories from the Titan Age.
• The Wells of Forgotten Names: Sacred wells holding names deliberately erased from mortal and divine remembrance.

Typical inhabitants include Titan-age petitioners, elder household retainers, Dactyls, Meliai, ancient craftsmen, memory-keepers, divine heralds, city guardians, primordial cyclopes and servants of surviving elder courts.

The White Expanse

Pale dunes and plains extend beneath a brilliant sky. White mountains rise in the distance, their slopes cut by monumental stairs, roads and terraces built for divine rulers and their households.

Sound travels immense distances and sometimes arrives years after it was made. Travellers may hear songs from an inhabited elder estate, arguments spoken before the Titanomachy or warnings uttered by companions who have not yet reached the region.

At the brightest hour of the day, buried roads and structures become visible beneath the dust.

The Buried Cities

Whole cities lie beneath Pelion.

Some were destroyed during the Titanomachy. Others were abandoned when their divine rulers were cast into Tartarean exile. Several remain inhabited beneath protective domes, sealed valleys or layers of white dust that open to recognised descendants, petitioners and sworn guests.

The cities retain impressions of coronations, rebellions, marriages, festivals, betrayals and final farewells. Recovering treasure without acknowledging its history can awaken the city’s unresolved emotions and surviving guardians.

Each city retains its own people, heirs, custodians and claims.

The Avenue of Nameless Statues

Colossal statues line a ceremonial avenue leading towards one of Pelion’s oldest courts.

Their faces remain intact, but many names and inscriptions were removed after the Olympian victory. Some represented condemned rulers. Others depicted neutral Titans, elder allies, servants, negotiators or witnesses whose existence complicated the victorious account of the war.

Different observers sometimes recognise different people in the same stone face.

Restoring a false name causes the statue to turn away. Restoring a true name allows it to speak once, revealing a memory that neither Pelion nor Olympus has been able to silence.

The Last Amphitheatre

An immense stage waits at the centre of a partially inhabited city.

The final act of its civilisation’s greatest epic was never performed. The surviving play recounts the Titanomachy from several perspectives: Olympian liberation, Titan betrayal, civil war, divine succession and the collapse of an entire cosmic order.

Spirits, scholars, gods and elder retainers disagree over whether completing the final act will reconcile Pelion with Olympus, free a condemned power, expose a false history or renew the ancient war.

The surviving fragments preserve several endings, and every faction claims a different one is authentic.

The Orchard Beneath the Dust

A living orchard survives within a sealed underground valley.

Its fruit contains memories belonging to Titans, servants, petitioners and mortal witnesses from the elder age. Eating the fruit grants the memory and its accompanying responsibility to the person who receives it.

The orchard’s keepers require every visitor to state why the memory is needed and what they intend to do when its truth becomes inconvenient.

The Wells of Forgotten Names

Deep stone wells contain names erased from mortal and divine remembrance.

Some names belong to defeated Titans. Others belong to servants, cities, children, witnesses and peacemakers omitted because their existence disturbed a simpler account of victory.

Speaking into a well may return one lost name, but another forgotten name rises beside it. A name restored to the world may awaken loyalties, debts, inheritance claims, divine obligations and enemies that have waited since the Titan Age.

Inhabitants

Petitioners

The dead who reach Arborea remain people.

They form households, artistic companies, athletic societies, orchards, theatres, travelling communities, sea-going settlements and elder households. Some retain clear memories of mortal life. Others remember through skills, relationships, emotions, songs or recurring dreams.

They possess homes, loyalties, dignity and the right to refuse the commands of those who mistake the dead for servants, raw spiritual material or scenery.

Nymphs, Dryads and Water Spirits

Nymphs embody living places and the relationships that sustain them.

Dryads are associated with trees and groves, naiads with freshwater and nereids with seas and oceanic places.

The Meliai are ash-tree nymphs with ancient ties to the transition between the Titan and Olympian ages. Some maintain sacred groves in Pelion, while others dwell in the Olympian Glades.

A spirit’s bond to a place gives that spirit standing, responsibility and a direct voice in how the place is treated.

Satyrs and Centaurs

Satyrs and centaurs inhabit the Olympian Glades in independent communities.

Satyrs serve as musicians, vintners, herders, scouts, hosts, provocateurs and guardians of ecstatic traditions. Centaurs maintain families, herds, sacred grounds, athletic societies, schools and travelling settlements.

Their communities contain artists, healers, teachers, warriors, parents, judges, farmers and philosophers.

Sea Peoples

Nereids, ichthyocentaurs and other recognised aquatic peoples inhabit Ossa.

Their settlements may be mobile, submerged, amphibious or grown from living reef. Migration rights, songs, storms, currents and responsibility for the health of the sea matter more than fixed borders.

Celestial Spirits

Chaotic-good celestial beings serve as guardians, messengers, healers, artists, defenders and witnesses.

Celestial service preserves individual judgement. A celestial may challenge a divine command that violates hospitality, personhood or meaningful freedom.

Sacred Animals

Swans, eagles, lions, deer, horses, bears, dolphins and celestial pegasi are found across the plane.

They possess their own habits, migrations and sacred places. Fellowship, trust and recognised service determine whether one accompanies a hero.

Primordial Cyclopes

The ancient primordial cyclopes associated with elder powers and Olympian forges may be encountered around divine workshops, volcanic halls, Pelion’s monumental cities and the approaches to Mount Olympus.

They are powerful individuals and organised households, often responsible for works that neither mortal builders nor lesser spirits can repair.

Titan-Age Petitioners and Retainers

Titan-age petitioners and retainers form a social category containing many peoples and individual forms.

They include dead worshippers of elder gods, hereditary household servants, ancient craftsmen, archivists, heralds, oath-witnesses, gardeners, city guardians and communities whose allegiance predates the Olympian settlement.

Pelion’s communities include Dactyls, Meliai, primordial cyclopes, nymphs, created guardians and petitioners whose forms express their former duties.

These communities possess law, property, loyalties, grievances and authority over their own history.

Heroes, Visitors and the Hellenic Dead

The heroes and rulers recorded among the Hellenic NPCs possess individual stories, loyalties and present circumstances.

Living heroes may enter through divine invitation, sacred voyage, dream, performance or exceptional deed. Dead heroes may become petitioners where their individual fate, divine allegiance and judgement place them.

A famous name grants reputation rather than automatic authority. Petitioners may honour, challenge, reject or hold a celebrated hero accountable for acts concealed by mortal legend.

Divine Powers

No single god rules all Arborea.

Divine powers can reshape their own realms, command recognised servants and influence neighbouring regions, but the plane’s deeper nature resists absolute government.

The Olympian Order

Mount Olympus is the principal realm of the Olympian gods within the Olympian Glades.

The Olympians hold supreme political authority across much of the first layer, but personality, kinship, hospitality, favour, old promises and heroic achievement shape how that authority is exercised.

Divine rank establishes precedence. Courage, truth and freely given loyalty establish lasting influence.

Dionysus holds particular influence over the Thunder Vineyards, their theatres, sacred harvests and travelling Bacchanalia. His authority is strongest where wine, performance and ecstatic experience reveal truth or restore freedom. Revels founded upon coercion, captivity or the destruction of another person’s judgement fall outside his rightful hospitality and draw the anger of the vineyards.

The Sea Powers of Ossa

Ossa contains courts, sanctuaries, embassies and sacred waters associated with the Hellenic sea powers.

Poseidon maintains one of his principal divine realms within Ossa. His sea court moves between storm-crowned islands, immense submarine halls and palaces raised from the waves by the strike of his trident.

This realm serves as his Arborean seat of authority over Hellenic seas, storms, earthquakes, horses, voyages and coastal peoples. It receives mariners, aquatic petitioners, ambassadors from Mount Olympus and envoys from communities throughout Ossa.

Poseidon also retains an Olympian hall upon Mount Olympus and a powerful connection to the Elemental Plane of Water. His court in Ossa is therefore one of his principal divine seats rather than his only residence.

Older currents preserve the names and influence of Oceanus and Tethys, together with the river gods, Oceanids, nereids and other divine lineages associated with them.

Poseidon is the most powerful Olympian authority in Ossa, but no single court owns every current, island, migration or settlement. Older sea powers, independent nereids, river gods, aquatic peoples and travelling communities retain their own waters, rights and allegiances.

Poseidon’s commands carry immense force near his court and throughout waters that recognise his protection. Beyond those regions, authority depends upon oath, kinship, hospitality, ancient treaty and the willingness of Ossa’s peoples to follow him.

The Surviving Elder Courts

Pelion preserves estates, sanctuaries and households belonging to the elder order that survived beyond the prisons of Carceri.

Some are governed directly by surviving divine powers. Others are governed by heirs, petitioners, councils, heralds or retainers acting under ancient instructions.

The elder courts form several independent houses rather than one united Titan government. Their relationships with Olympus range through loyalty, kinship, guarded neutrality, formal reconciliation, rivalry and unresolved grievance.

The Exiled and Condemned

Othrys, the first layer of Carceri, is the realm of exiled Titans and banished gods.

Cronus remains imprisoned in Tartarus and rules the Palace of the Titans from within his confinement. Other elder powers possess individual sentences, duties, reconciliations or realms according to their own histories.

Pelion therefore embodies the surviving elder civilisation, while Othrys embodies defeat, exile, imprisonment and resentment.

Law, Personhood and Consequences

Arborea recognises personhood through mind, will, relationship, responsibility and established standing rather than creature type, age or divine allegiance.

Petitioners, nymphs, satyrs, centaurs, sea peoples, celestials, Titan retainers and other thinking inhabitants may possess homes, inherit obligations, give testimony, demand restitution and receive the protection of their communities.

Guest-Right

A formal welcome places both host and guest under obligation.

The host must provide protection, sustenance and a clear opportunity to depart. The guest must respect the household, refrain from treachery and declare any known danger brought to the host’s door.

A violation of guest-right may bring public shame, divine displeasure or the closing of every hospitable door within the region.

Oaths and Agreements

Freely sworn oaths carry great weight.

Witnesses, sacred places and the emotional truth of the promise matter more than elaborate written forms. Coercion, deception and concealed conditions weaken an oath and may render it powerless.

Memory, Names and Testimony

Stealing memories, erasing names, falsifying monuments and silencing witnesses are serious wrongs.

A person who restores a lost memory becomes its witness rather than its owner. The person or community whose history has been recovered decides how it may be preserved, shared or acted upon.

Serious Wrongs

The gravest offences include enslavement, magical domination, treacherous murder, imprisonment under the guise of hospitality, destruction of a spirit’s bonded place, theft of names or memories and deliberate suppression of testimony.

Judgement and Restitution

Some divine realms maintain formal courts, but many Arborean communities rely upon assemblies, respected witnesses, elders, poets, champions and public testimony.

Common consequences include restitution, the return of stolen works or memories, restoration of damaged land, public acknowledgement, service freely accepted by the injured party and exile where trust cannot be restored.

Punishment without repair carries little honour.

Duels and Contests

A duel or contest is lawful only when all participants understand and accept its terms.

Intimidation, enchantment, concealed rules or the inability to withdraw invalidates the contest. A victory achieved through coercion brings shame rather than honour.

Killing

Killing in defence of another person may be praised. Killing for humiliation, vengeance or pleasure remains subject to judgement.

A victor who continues violence after the danger has ended may find the landscape preserving the victim’s final experience until the wrong is answered.

Travel

Reaching Arborea

Stable entrances may appear within:

• sacred groves and ancient orchards;
• old theatres where a forgotten work is performed correctly;
• mountain sanctuaries touched by divine storms;
• islands reached during supernatural weather;
• festivals founded upon genuine hospitality;
• places of communal mourning;
• sites where captives have just won meaningful freedom;
• works of art completed through shared sacrifice;
• monuments where a deliberately erased name has been restored;
• Titan-age sanctuaries reopened by recognised heirs or retainers.

The earthly Mount Olympus is an important Material Plane anchor. Reaching the planar summit requires divine invitation, a recognised sacred passage or an exceptional mythic act.

Moving Between Layers

The three layers are joined through divine gates, sacred rivers, living ocean currents, storms that cross from mountain to sea, performances that recreate forgotten voyages and ancient arches uncovered beneath Pelion’s dust.

Rivers and springs may connect Pelion to Ossa. Divine processions, old treaties and restored names can open passages between Pelion and the Olympian Glades.

Travel presents meaningful choices and consequences while allowing each region’s people, conflicts and discoveries to remain central.

Leaving Arborea

Recognised gates, divine passages and planar magic allow travellers to depart.

Some visitors remain because Arborea offers belonging, inspiration or emotional fulfilment that they have never found elsewhere. The freedom to depart gives the choice to remain its meaning.

Arborea in the World

Arborea touches the mortal world most strongly through Greece, the Mediterranean, sacred mountains, old theatres, groves, vineyards, springs, islands and communities where people gather freely to celebrate or mourn.

Its influence can also appear wherever:

• a ruler is publicly challenged through art;
• a captive people wins meaningful freedom;
• strangers receive protection without hidden obligation;
• a community allows grief to be spoken openly;
• rivals choose creation over inherited hatred;
• a festival restores its participants rather than consuming them;
• a promise is kept despite the absence of force or reward;
• a suppressed witness is finally heard;
• a monument’s false history is corrected;
• an old community survives the fall of its rulers while preserving its identity.

Hellenic traditions recognise Mount Olympus as Arborea’s strongest divine anchor in the mortal world, but the plane’s influence reaches every society capable of hospitality, mourning, artistic truth, remembered history and freely chosen loyalty.

Artists, lovers, mourners, athletes, rebels, hosts, historians and travellers may encounter Arborea’s influence without learning its planar name.

Game Mechanics

The rules below are mechanics compatible for different game editions.

Adventure Hooks

The Feast Without Dawn

A celebrated festival has continued for thirty years. Every guest appears happy, but anyone who tries to leave forgets why departure mattered.

The Silent Voice

Part of the Wild Choir has fallen silent. The missing voice belongs to a dryad whose tree was secretly moved into a divine garden.

The Wrong Ending

A newly recovered fragment gives the Last Amphitheatre’s account of the Titanomachy a peaceful conclusion. Olympus, Othrys and three surviving elder courts each insist that the fragment is false.

The Returning Island

An island rises in Ossa whenever two estranged rulers consider reconciliation. Someone is killing their messengers to keep the island beneath the sea.

The Stolen Vintage

Wine containing the courage of an ancient rebellion has been stolen from the Thunder Vineyards. A mortal tyrant intends to serve it to soldiers while erasing every memory of what they once opposed.

The Nameless Titan

A statue in Pelion bears the face of a Titan officially recorded as imprisoned in Tartarus. Restoring the statue’s name may reveal an escape, a false history, a divided identity or two powers claiming the same divine name.

The Unopened Court

A buried city sends formal invitations to Olympus, Ossa and the mortal world. Its Titan ruler vanished during the war, but the household has continued obeying the last lawful command for thousands of years.

The Memory Claimed by Three Gods

A fruit from the Orchard Beneath the Dust contains proof of an ancient promise. An Olympian god, a surviving elder court and an imprisoned power each claim authority over the memory.

Historic and Mythic Context

Arborea is a cosmological realm shaped from several Hellenic mythic, literary and religious traditions. Ancient Greek traditions present distinct divine homes, underworld regions, blessed destinations, sacred landscapes and cosmic waters rather than one unified plane identical to Arborea.

Hesiod’s Theogony provides one of the most influential surviving accounts of divine generations, the succession from Uranus to Cronus and from Cronus to Zeus, and the conflict between Titans and Olympians. SpiralWorlds develops this succession as the historical foundation of Pelion and the Olympian Glades.

The Hellenic Pantheon preserves primordial gods, Titans, Olympians and chthonic powers as active divine categories. Arborea reflects that hierarchy while allowing each maintained deity entry to determine that power’s present realm, alliances, imprisonment and activity.

In Homer’s Iliad, Olympus appears as the gathering place and divine home of the gods. SpiralWorlds connects this literary and cultic mountain with the mortal Mount Olympus and the planar summit that dominates the Olympian Glades.

The public theatres, divine feasts, rivalries, hospitality and contests of the first layer also draw upon the social and religious world reflected in the Homeric Hymns and the athletic victory traditions preserved in Pindar’s Olympian Odes.

Ossa draws upon the mythic importance of the Mediterranean and the greater world-encircling waters: voyages, storms, islands, sea divinities, shipwrecks, transformations and the boundary between the known world and the marvellous. Homer’s Odyssey gives the layer its language of departure, wandering, changing identity, uncertain islands and difficult return.

Ossa’s older waters also draw upon Oceanus, Tethys, the Oceanids, river gods, nereids and other aquatic lineages maintained within the Hellenic Pantheon and Bestiary. Their mythic influence shapes Ossa even where an individual deity’s permanent residence lies elsewhere.

Pelion develops the campaign’s Titan Age. It preserves the cities, households, memories and sacred works that survived the Titanomachy outside Tartarean imprisonment. Othrys in Carceri serves as the realm of exiled Titans and banished gods, creating a clear cosmological distinction between the surviving elder civilisation and the defeated powers held in prison.

The mortal Mount Pelion is strongly associated with centaurs, Chiron, heroic education and the generation of heroes who preceded the Trojan War. Apollonius of Rhodes’ Argonautica preserves important traditions concerning Pelion, the Argonauts and the heroic world. Those traditions inform the planar layer’s elder schools, remote estates and monumental inheritance.

The heroes, kings, seers, nymphs and travellers recorded in the Hellenic NPC collection may enter Arborea as visitors, petitioners, honoured guests or adversaries according to their individual histories. Their legendary status does not make every Hellenic hero a permanent resident of the plane.

The sacred groves, springs, ruins, roads, shrines and local divine traditions described by Pausanias in Description of Greece support Arborea’s treatment of landscape as inhabited, remembered and morally significant.

The Olympian Glades, Ossa and Pelion also perform distinct cosmological roles within SpiralWorlds. The Beastlands express freedom through instinct and living wilderness; Ysgard expresses freedom through heroic struggle; and the Fey World expresses enchantment through fey nature, desire and transformation. Arborea centres freely chosen bonds, emotional truth, artistic creation, hospitality and sacred memory.

Historical and mythic sources therefore provide Arborea’s foundation, while this entry remains the authoritative description of the plane within the SpiralWorlds campaign.
