The Four Ruinous Powers

Gods Shaped by Mortal Souls

The Ruinous Powers are vast intelligences within the Warp.

They are shaped and sustained by the emotions, actions, beliefs, and desires of living beings. Every war, ambition, plague, obsession, betrayal, triumph, and moment of despair contributes to the Immaterium.

The Chaos Gods are not distant observers.

They influence dreams, reward champions, empower cults, send daemons, corrupt institutions, and manipulate events across centuries.

They do not value mortal lives as individuals. A worshipper may be beloved, rewarded, abandoned, or destroyed according to how well they serve a greater purpose.

Khorne

Khorne is the god of bloodshed, rage, warfare, martial pride, and violent strength.

He draws power from every act of deliberate violence, whether committed by a loyal soldier, criminal, rebel, alien warrior, or devoted cultist.

Khorne’s influence often begins with understandable desires:

• Strength to defeat an enemy

• Courage in battle

• Revenge for a wrong

• Hatred of cowardice

• Contempt for manipulation

• Desire for martial honor

• Refusal to appear weak

Over time, strength becomes domination, courage becomes recklessness, and honor becomes endless killing.

Khorne rewards warriors with physical power, endurance, speed, resistance to pain, and supernatural skill. His servants may develop horns, hardened flesh, burning eyes, unnatural muscle, or weapons fused with their bodies.

Khornate followers often distrust sorcery and complex schemes. They prefer direct confrontation, though their leaders can still be disciplined commanders.

Khorne does not care why blood is spilled.

He cares that it flows.

Tzeentch

Tzeentch is the god of change, ambition, sorcery, fate, knowledge, and manipulation.

His influence attracts those who believe the present order must be altered.

Common temptations include:

• Forbidden knowledge

• Escape from oppression

• Political advancement

• Psychic mastery

• Prophetic certainty

• Transformation

• Revenge through planning

• The power to change destiny

Tzeentch rarely offers simple answers.

His servants may receive genuine knowledge, but that knowledge often creates dependence, paranoia, or obligations they do not understand.

Tzeentchian corruption may produce shifting bodies, additional eyes, feathered growths, changing voices, psychic flame, unstable memories, and mutations that reflect hidden potential.

His cults often operate through secret societies, scholarly orders, revolutionary movements, political factions, and prophetic faiths.

A Tzeentchian plot may fail exactly as intended because the failure creates another future.

Change is both his gift and his trap.

Nurgle

Nurgle is the god of disease, decay, despair, endurance, stagnation, and corrupted affection.

He often reaches those who are exhausted, dying, trapped, grieving, or terrified of what comes next.

His promises include:

• Relief from pain

• Freedom from fear

• Survival against disease

• Strength to endure

• Acceptance of loss

• Belonging within a community

• Escape from hopelessness

Nurgle does not usually remove suffering.

He changes his followers until suffering feels normal, comforting, or even joyful.

His servants may become swollen, diseased, rusted, scarred, overgrown, or surrounded by insects and toxic growth. Despite their appearance, they may possess incredible resilience.

Nurglite followers often display loyalty, humor, patience, and distorted kindness. They may sincerely believe that spreading disease shares the peace they have found.

Nurgle represents the danger of surrendering all hope of change.

Slaanesh

Slaanesh is the god of excess, obsession, sensation, pride, perfection, desire, and self-indulgence.

Slaanesh reaches anyone who believes that one more achievement, experience, victory, or sensation will finally make them complete.

Common temptations include:

• Artistic perfection

• Martial mastery

• Recognition

• Beauty

• Authority

• Emotional intensity

• Unmatched skill

• Revenge through superiority

• Freedom from restraint

Slaanesh does not require one specific form of desire.

A warrior obsessed with the perfect duel, a preacher demanding flawless devotion, a noble seeking admiration, and an artist sacrificing everything for one masterpiece may all attract the same power.

Slaaneshi corruption may create heightened senses, unnatural grace, perfect symmetry, altered voices, excessive confidence, elegant mutations, or growing dependence upon stronger experiences.

Satisfaction never lasts.

Every success creates a greater hunger.

Gifts of Chaos

The Ruinous Powers reward useful servants.

Possible gifts include:

• Increased strength

• Psychic abilities

• Resistance to disease

• Supernatural speed

• Prophetic visions

• Regeneration

• Enhanced senses

• Daemonic weapons

• Command over cultists

• Mutation

• Authority among Chaos forces

A gift may solve a real problem.

It may also mark the recipient, create an obligation, impose a compulsion, or make ordinary life increasingly impossible.

Chaos gifts should feel tempting enough that accepting them is a genuine choice.

Marks and Allegiance

A servant who earns special favor may receive the mark of a Chaos God.

A mark may appear as:

• A physical mutation

• A supernatural aura

• A recurring symbol

• A change in voice or shadow

• Resistance associated with the patron

• Recognition by daemons

• A compulsive behavior

• A visible sign upon armor or flesh

A marked champion gains power but becomes more closely bound to their patron.

Rejecting that patron afterward may be extraordinarily difficult.

The Great Game

The Chaos Gods wage an eternal struggle known as the Great Game.

They fight for influence, territory, souls, champions, and dominance within the Warp.

Their rivalries shape mortal conflicts.

Khorne despises Tzeentch’s sorcery and manipulation.

Tzeentch opposes Nurgle because constant change conflicts with stagnation and acceptance.

Nurgle and Slaanesh clash over resignation against endless hunger.

Slaanesh competes with Khorne over pride, violence, and the pursuit of mastery.

These rivalries are not absolute. The powers may cooperate when facing a shared threat or when temporary unity serves a larger purpose.

Any alliance between them remains unstable.

Rival Cults

Chaos cults often fight one another as fiercely as they fight the Imperium.

A Khornate gang may slaughter a Tzeentchian conspiracy. A Nurglite sect may undermine Slaaneshi nobles. Rival prophets may compete for one population.

These conflicts create opportunities for the party.

Characters may exploit rivalry, manipulate one cult against another, or discover that destroying one faction allows a worse enemy to take its place.

Recognizing Influence

The presence of a Ruinous Power may be revealed through recurring patterns.

Khorne: escalating violence, ritual duels, skull imagery, hatred of psykers, bloodshed without strategic purpose.

Tzeentch: secret messages, contradictory prophecies, mutation, hidden societies, impossible coincidences, shifting plans.

Nurgle: disease, rust, insects, despair, resilience, communities accepting decay, corrupted healing.

Slaanesh: obsession, perfectionism, sensory excess, elegant cruelty, addiction, pride, increasingly extreme behavior.

These signs are clues, not proof.

A violent soldier does not automatically serve Khorne. A sick population is not necessarily Nurglite. Characters should investigate before reaching conclusions.

Worship and Ignorance

Many servants of Chaos do not know the true name of the power they serve.

A cult may worship:

• A war spirit

• A god of change

• A saint of endurance

• A muse of perfection

• An ancestral force

• A hidden liberator

• A planetary deity

• A prophetic machine

The Chaos God may accept worship under any name if the emotions and actions serve its nature.

This allows corruption to grow inside societies that believe they remain loyal.

Choosing a Patron

Chaos-aligned player characters may follow one of the four powers.

Their patron should influence:

• Motivations

• Appearance

• Abilities

• Temptations

• Enemies

• Faction relationships

• Corruption

• Long-term goals

A follower should not be forced into mindless behavior.

A Khornate warrior can be disciplined. A Tzeentchian cultist can value companions. A Nurglite survivor can seek a cure. A Slaaneshi champion can attempt restraint.

The tragedy lies in how difficult those choices become as corruption grows.

The Ruinous Powers in Play

The four Chaos Gods provide distinct themes for adventures.

Khorne supports stories of war, revenge, courage, and violence.

Tzeentch supports conspiracy, prophecy, ambition, mutation, and hidden knowledge.

Nurgle supports survival, plague, despair, loyalty, and corrupted comfort.

Slaanesh supports obsession, perfection, pride, temptation, and excess.

Their influence should appear through people and choices before daemons and mutations become obvious.

Chaos becomes most dangerous when its offer appears reasonable.

The path to damnation rarely begins with a desire to destroy the galaxy.

It begins with wanting the strength to change one small part of it.
