SpiralWorlds Cosmology

Energy Planes — Positive Energy and Negative Energy

Positive and Negative Energy are two of reality’s oldest cosmic pressures: one drives incarnation, growth, repair and renewal; the other drives release, dissolution, depletion and unmaking. Neither is inherently good or evil, and both can kill an unprotected traveller.

Creation and dissolution are not moral opposites. They are dangerous cosmic forces through which living worlds become, change and eventually release what they cannot keep forever.

Positive and Negative Energy at a Glance

Positive Energy

Becoming
Incarnation and vitality
Growth and multiplication
Repair and healing
Renewal and fertility
Lethal overgrowth and overload
Destabilises many undead
Not inherently Good

Negative Energy

Release
Depletion and cessation
Dissolution and decay
Entropy and unmaking
Life drain
Lethal depletion and negation
Can sustain many undead without belonging to them
Not inherently Evil

The essential distinction: Positive Energy is not a reward for virtue and Negative Energy is not punishment for wickedness. A tyrant can be healed by Positive Energy. A saint can be destroyed by too much of it. Negative Energy ends and releases, but evil beings can exploit that function without defining what the plane itself means.

The Two Cosmic Poles

Positive Energy Plane

Life Without Limit

The Positive Energy Plane is an infinite radiance of generative force. It feeds incarnation, healing, fertility, restoration and the animating spark of life, but it has no instinct for moderation.

Exposed travellers first feel healthier. Pain eases, wounds close and senses sharpen. Then the same process becomes dangerous. Flesh grows past its limits, vitality accumulates faster than a mortal body can contain it and healing becomes overload.

Survivable regions include refraction isles, jyoti crystal cities, protected sanctuaries, soul-orchard approaches and carefully controlled star-gates.

Negative Energy Plane

The Void of Entropy

The Negative Energy Plane is the cosmic pressure of depletion, dissolution and release. It strips heat, vitality, structure and eventually identity from things that remain exposed to it.

It is not an underworld and it is not where the dead are meant to go. Undead and necromancers exploit its power, but the Void predates necromancy and can ultimately unmake the unliving as readily as the living.

The Near Dark, warded anchors, dead-world fragments and entropy-crystal outskirts provide the most plausible destinations for prepared mortal expeditions.

Cosmological Role

The Energy Planes are cosmic infrastructure, not divine kingdoms. Gods may draw upon them, guard breaches, fear their misuse or build temporary holdings near them. No later god created or owns either source.

In SpiralWorlds cosmology, existence first develops an ancient polarity of becoming and release. From the Great Collision emerge the Energy Planes as primal anchors: Positive drives incarnation, accumulation and renewal; Negative receives dissolution, exhaustion and the end of processes that cannot continue forever.

The Elemental Planes give substance its fundamental forms. The Material Plane lets energy and substance become bodies, oceans, forests, fires, kingdoms, wounds, graves and histories. Negative Energy receives the pressure of endings; Positive Energy keeps new becoming possible.

Positive Energy → Elemental Substance → Material Life and Change → Death, Decay and Release → Negative Energy

This is not a simple conveyor belt through which every soul is mechanically processed. Souls, afterlives, divine judgement, reincarnation, ghosts and underworlds have their own laws. The Energy Planes describe fundamental cosmic pressures, not the entire spiritual history of a person.

Life, Death, Undeath and Negation

The old habit of treating Positive Energy as “life” and Negative Energy as “undeath” hides several important distinctions.

Life

Life is embodied existence: a living creature sustained by matter, vitality, identity and whatever spiritual laws govern its kind.

Death

Death is the end of bodily life and, in many traditions, the beginning of another passage involving soul, judgement, memory, burial, ancestry or reincarnation.

Undeath

Undeath is a supernatural interruption, transformation, animation or refusal of ordinary death. Negative Energy may power it, but that does not make undeath the natural purpose of the Negative Energy Plane.

Negation

Negation is the Void’s deeper pressure: reduction, depletion and unmaking without judgement, hatred or concern for what the thing once meant.

This distinction is central to Necromancy. Necromancy can manipulate life force, corpses, spirits, death and undeath without making all of those things identical.

Older rules traditions also connect these forces strongly to the Cleric, particularly through healing, turning, rebuking and channelled energy. SpiralWorlds does not require every healing spell or divine miracle to mean a god literally opens a conduit to one of these planes. The Energy Planes remain deeper cosmological sources rather than property belonging to one class or pantheon.

Death is a passage. Undeath is an interruption. Negation is the Void. A ghost that falls into the Negative Energy Plane may need rescue rather than destruction, and a death god may oppose a Void breach precisely because lawful death is not the same thing as erasure.

Native Peoples and Planar Claims

Neither Energy Plane should be treated as an empty battery waiting for spellcasters to exploit. Both have native interests that can turn planar travel into diplomacy, trespass, theft or war.

Jyoti

Jyoti are the principal native guardians of the Positive Energy Plane. Radiant and phoenix-like, they inhabit living crystal cities, guard star-gates, protect soul-orchards and quarantine relics that are too dangerous to enter later worlds.

Their beautiful realms are not celestial heavens and the jyoti are not gentle angelic hosts. They are territorial, suspicious and extremely protective of pre-incarnate souls and the infrastructure of creation.

Sceaduinar

Sceaduinar are the principal true people of the Negative Energy Plane, arising from entropy-crystal formations in the deep Void.

They hate life because it bears the spark of creation, but they also hate undeath as stolen movement imposed on what should have ended. Their existence prevents the Negative Energy Plane from becoming merely an “undead plane.”

The hostility between jyoti and sceaduinar is one of the major hidden conflicts of the Energy Planes, but it should not be reduced to Good versus Evil. It is a struggle between beings adapted to radically opposed cosmic principles.

Travel, Arrival and Survival

Plane Shift solves the problem of crossing between planes. It does not solve the problem of arriving somewhere survivable.

The Planar Campaigns guide covers expedition planning in greater depth. Energy-plane journeys should be treated as high-pressure expeditions with prepared entry points, limited exposure and a known return route.

Question	Positive Energy Plane	Negative Energy Plane
Primary danger	Excess vitality, blinding radiance and positive overload.	Life drain, necrotic exposure, exhaustion and eventual unmaking.
Best arrival	Refraction isle, jyoti gate-court, crystal shelf or warded sanctuary.	Warded anchor, Near Dark site, dead-world fragment or controlled entropy-crystal outskirts.
Breathing	Exposed radiance is usually airless; safe pockets may provide atmosphere.	Ordinary breathable conditions cannot be assumed; warded anchors provide survivable reality pockets.
Light	Overwhelming radiance; light itself acts as environmental pressure.	Light is swallowed or suppressed as travellers move deeper into the Void.
Healing	Strengthened, but excess healing contributes to lethal overcharge.	Impeded outside stable protection.
Undead	Usually damaged, destabilised or unable to recover normally.	Many survive better than living creatures but are not universally safe, especially in deeper regions.
Soul danger	Interference with pre-incarnate souls or reckless resurrection can trigger jyoti intervention.	Souls can be trapped, misdirected or endangered by deep negation.
Return plan	Keyed gate, star-gate permission, planar focus or sanctuary route.	Warded anchor, keyed portal, soul-tether and reliable planar exit.

Arrival Is Already an Encounter

Before an Energy Plane expedition begins, answer four questions:

What keeps the party alive during the first minute?
Where is the nearest sanctuary or controlled region?
What local native power considers that arrival site its territory?
What event or resource forces the party to leave before its protection fails?

Energy Planes Mechanics

These rules answer the immediate question: what changes when a creature physically enters one of the Energy Planes? Detailed regions, hazards and adventure procedures remain on the two child-plane guides.

5.5e-Compatible Energy Plane Rules

The current SRD provides the modern rules framework but does not publish a complete Positive/Negative energy-plane hazard system. The procedures here are SpiralWorlds-compatible rules inherited from the detailed Positive and Negative Energy Plane entries.

Positive Energy — Minor Dominance

At the start of its turn, a living creature with at least 1 hit point regains hit points equal to its Proficiency Bonus if it is below its hit point maximum.
If already at full hit points, it gains 1d6 temporary hit points instead. These are positive overcharge.
Undead and creatures primarily animated by negative energy take radiant damage equal to twice the party’s Proficiency Bonus at the start of their turns.

Positive Energy — Major Dominance

At the start of its turn, a living creature with at least 1 hit point regains 10 hit points if below maximum.
A creature already at maximum instead gains 10 temporary hit points as positive overcharge.
At positive overcharge equal to at least half the creature’s hit point maximum, it makes a DC 15 Constitution saving throw at the end of each turn. Failure blinds it until the end of its next turn and gives it one level of Exhaustion from radiant overload.
At positive overcharge equal to or greater than its hit point maximum, it instead makes a DC 20 Constitution saving throw at the end of each turn. Failure causes radiant rupture.
Radiant rupture reduces the creature to 0 hit points and it begins dying normally. If already at 0 hit points, or if the saving throw was failed by 5 or more, the creature dies.

When a creature first enters exposed major radiance, use the detailed Positive Energy Plane rule for blinding brilliance: DC 15 Constitution.

See the complete Positive Energy Plane entry for healing magic, resurrection, protection, undead exposure and pre-incarnate soul contact.

Negative Energy — Exposure Bands

A living creature without suitable planar protection, a stable warded anchor or another specific defence uses the following exposure procedure.

Region	Save Interval	Save	Failed Save
Near Dark	1 hour	DC 14 Constitution	10 necrotic damage and 1 Exhaustion.
Deep Void	10 minutes	DC 18 Constitution	21 necrotic damage and 1 Exhaustion.
Still Heart	1 round	DC 22 Constitution	45 necrotic damage, 1 Exhaustion and soul risk.

On a successful Void exposure save, the creature takes half damage and gains no Exhaustion from that exposure.

Healing in the Void

Outside a warded anchor, when a spell or magical feature restores hit points to a living creature, the caster makes a DC 15 spellcasting ability check. On success the healing works normally. On failure it restores only half the normal hit points.

See the complete Negative Energy Plane entry for light suppression, resurrection instability, undead benefits, gravewinds, ward stability and soul-danger procedures.

Rules Authority

These two sets of procedures are not universal rules for every campaign cosmology. They are the SpiralWorlds 5.5e-compatible implementation of the two Energy Planes and should be used consistently with the corresponding child entries.

Pathfinder 1e Energy-Dominant Traits

Pathfinder uses explicit minor and major positive-dominant and negative-dominant planar traits.

Trait	Pathfinder 1e Effect
Minor Positive-Dominant	All creatures gain fast healing 2.
Major Positive-Dominant	On entry, a creature makes a DC 15 Fortitude save or is blinded for 10 rounds. Creatures gain fast healing 5. A creature at full normal hit points gains 5 temporary hit points each round.
Positive Overload	Once temporary hit points from major positive dominance exceed the creature’s normal hit point total, it makes a DC 20 Fortitude save each round. Failure kills the creature in a burst of energy.
Minor Negative-Dominant	Living creatures take 1d6 damage each round. A creature reduced to 0 hit points or lower crumbles to ash.
Major Negative-Dominant	Each round a creature makes a DC 25 Fortitude save or gains one negative level. If its negative levels equal its current levels or Hit Dice, it dies and becomes a wraith under the classic planar rule.
Death Ward	Protects a traveller from the damage and energy drain of negative-dominant planar traits.

Positive Energy Plane Magic

Positive-energy spells and spell-like abilities are enhanced. Pathfinder’s plane-specific rule gives class abilities using positive energy—such as channel positive energy—a +4 bonus to the save DC. Negative-energy magic is impeded.

Negative Energy Plane Magic

Negative-energy spells and spell-like abilities are enhanced. Class abilities using negative energy gain a +4 bonus to the save DC. Positive-energy magic, including cure spells, is impeded.

Characters on the Negative Energy Plane also take a –10 penalty on saving throws to remove negative levels bestowed by energy drain.

Impeded Magic

Under the Pathfinder planar rule, casting an impeded spell requires a concentration check, DC 20 + spell level. Failure means the spell does not function but the prepared spell or spell slot is still lost.

D&D 3.5e Energy-Dominant Traits

The 3.5 SRD uses the classic minor and major positive-/negative-dominant planar traits. The environmental core resembles Pathfinder, but the plane-specific enhanced magic rules are different.

Trait	D&D 3.5e Effect
Minor Positive-Dominant	Creatures gain fast healing 2.
Major Positive-Dominant	DC 15 Fortitude or blinded for 10 rounds; fast healing 5; creatures already at full hit points gain 5 temporary hit points each round.
Positive Overload	Once temporary hit points from the plane exceed the creature’s normal hit point total, it makes a DC 20 Fortitude save each round. Failure kills the creature.
Minor Negative-Dominant	Living creatures take 1d6 damage each round.
Major Negative-Dominant	DC 25 Fortitude each round or gain one negative level. Accumulating negative levels equal to the creature’s levels or Hit Dice kills it.

Positive Energy Plane Magic

Spells and spell-like abilities using positive energy, including cure spells, are maximized without requiring higher-level spell slots.

Class abilities that use positive energy, such as turning and destroying undead, gain a +10 bonus on the roll to determine Hit Dice affected.

Negative-energy magic, including inflict spells, is impeded.

Negative Energy Plane Magic

Spells and spell-like abilities using negative energy are maximized without requiring higher-level spell slots.

Rebuking and controlling undead gains a +10 bonus on the roll to determine Hit Dice affected.

Positive-energy magic, including cure spells, is impeded. Characters also take a –10 penalty on Fortitude saves made to remove negative levels bestowed by an energy drain attack.

Keep the Editions Separate

Do not replace the 3.5e maximization and turning/rebuking bonuses with Pathfinder’s later +4 channel-energy save DC rule. They are different mechanics.

Running Energy-Plane Adventures

Both planes work best as short, purposeful expeditions rather than ordinary wilderness maps.

Use Positive Energy for Excess

The dramatic question is rarely “can the party find healing?” It is “how much life can a mortal body, kingdom or ecosystem safely contain?”

A healing spring will not stop healing.
A ruler tries to seize a jyoti star-gate.
A plague cure becomes runaway growth.
A pre-incarnate soul has been stolen for a royal bloodline.
An undead witness must cross a plane that rejects its continued existence.

Use Negative Energy for Loss

The dramatic question is not merely “how many undead are here?” It is “what will disappear if the party cannot protect it?”

A ghost must be rescued before its memory is erased.
A lich is harvesting entropy crystals.
A black-star gate is opening above a city.
A dead-world ruin contains records from an erased civilisation.
Sceaduinar attack an undead engine because it violates proper ending.

Do not run either plane as a colour filter over a normal dungeon. Positive Energy should create pressure through uncontrolled vitality; Negative Energy should create pressure through depletion, failing protection and the danger of losing things that cannot simply be healed back.

Historical and Scientific Context

The Positive and Negative Energy Planes are fantasy roleplaying concepts, not historical religious places and not descriptions of real physical energies.

Older European philosophy and science sometimes used vitalist models in which life appeared to require a distinctive organising or animating principle beyond ordinary mechanical explanation. Those ideas provide a useful historical comparison for fantasy “life force,” but modern biology does not require a Positive Energy Plane to explain living processes.

Negative Energy is likewise sometimes compared metaphorically with entropy: the irreversible loss of usable order described in thermodynamics and statistical mechanics. The comparison can be evocative, but the Void’s life drain, soul-danger and necromantic uses are fantasy metaphysics, not literal physics.

Energy Planes Across Game Editions

Published fantasy cosmologies have moved the Positive and Negative Planes around the cosmological diagram and changed how strongly they are tied to healing, necromancy, undead and the Elemental Planes.

SpiralWorlds keeps a stable setting decision: Positive and Negative are the two primal Energy Planes associated with the older Inner cosmological order. They predate the later Astral and divine structures and remain cosmic infrastructure rather than moral afterlives.

The mechanics tabs above then use the rules appropriate to each supported edition rather than rewriting the setting every time a rulebook redraws the cosmological map.

The current 5.5e System Reference Document supplies the modern rules framework but omits the older Planes of Existence appendix. SpiralWorlds therefore labels its current-edition Energy Plane procedures as compatible setting mechanics rather than presenting them as official SRD planar rules.
