World Overview
Magic Level:
Medium “Magic” – supernatural influence is constant, but control is rare and dangerous. What is called Magic is actually Sanity interaction: the ability to perceive, resist, or slightly influence unstable reality without collapsing. Sanity replaces mana entirely.
Sanity System (Core Rule of the World):
Sanity represents a character’s mental integrity and perception of reality. The Backrooms constantly erode it. Low Sanity causes hallucinations, false memories, distorted environments, and increased entity attention. At zero Sanity, characters suffer a psychological collapse rather than instant death.
Warrior Culture:
Those who do not manipulate Sanity rely on Lucidity — pure willpower, grounding, and survival instinct. Lucidity allows characters to act under fear, resist possession, ignore pain, and function even at critically low Sanity. Lucidity is respected because it preserves humanity longer.
Geography & Nations
Geography & Nations
The Backrooms are divided into Levels, functioning like nations.
Each Level has:
Its own rules
Its own dangers
Its own sanity drain
Levels are procedurally endless.
No map is fully accurate.
Level 0 – The Yellow Maze (Starting Region):
Endless yellow corridors, buzzing lights, damp carpet.
Sanity drain is slow but constant.
Entities are rare but paranoia is high.
Level 1 – Storage Zones:
Warehouses and crates.
First factions appear here.
Moderate entity activity.
Level 2 – The Pipeworks:
Industrial tunnels, heat, steam.
High Lucidity checks required.
Entities hunt aggressively.
Level 3 – Electrical Stations:
Generators, cables, control rooms.
Sanity damage from noise and isolation.
Controls lighting in other Levels.
Procedural Levels (Endless):
After Level 3, Levels become semi-random:
-Hotels
-Schools
-Hospitals
-Malls
-Neighborhoods
-Each follows a theme + rule set, not a fixed map.
Races & Cultures
Races represent mental adaptation, not biology.
Humans:
Balanced. Adapt quickly but fragile.
Dwarves:
Extremely grounded. High Lucidity. Struggle with change.
Current Conflicts
Sanity vs. Lucidity Divide:
Awareness users manipulate reality.
Lucidity users resist it.
Each distrusts the other.
Faction Control:
Groups fight over:
-Safe Levels
-Light sources
-Maps
-Exit rumors
Entity Evolution:
Entities learn player behavior over time.
Repeated tactics stop working.
Magic & Religion
Magic (Sanity-Based):
Magic = controlled interaction with unstable reality.
Awareness:
Rare trait allowing:
-Minor reality anchoring
-Controlled hallucinations
-Recognition of false spaces
-Using Awareness always risks Sanity loss.
Types of “Magic”:
-Anchoring (stabilize area briefly)
-Recognition (detect fake exits)
-Distortion (alter small environmental rules)
-Lucidity vs. Sanity:
Sanity = perception integrity
Lucidity = willpower
High Lucidity lets you act at low Sanity — but at great risk.
Religion (Belief Systems):
Belief directly affects Sanity.
The Exit Belief:
Hope-focused.
Regain Sanity when progressing.
The Acceptance Belief:
Resist despair.
Lose motivation to escape.
Entity Worship:
Grants protection… at a price.
Planar Influences
The Backrooms are not a single plane, but an overlapping stack of unstable realities. Each Level is influenced by invisible planar forces that shape its rules, dangers, and psychological effects. These influences are not gods, but pressures exerted on reality.
The Plane of Stability:
Represents order, consistency, and mental grounding.
Levels under this influence have predictable layouts, functioning technology, and slower Sanity drain.
Light sources last longer, entities are rarer, and exits follow patterns.
The Plane of Distortion:
Represents broken logic and shifting perception.
Rooms loop, sizes change, sounds come from impossible directions.
Sanity loss increases, false exits appear, and entities mimic survivors more convincingly.
The Plane of Predation:
Represents hunger, pursuit, and awareness.
Levels feel watched. Entities are active, coordinated, and aggressive.
Staying too long draws attention regardless of noise or light.
The Plane of Echoes:
Represents memory and repetition.
Past events replay subtly. Voices repeat conversations.
Characters may encounter echoes of themselves or others, real or not.
Sanity damage often manifests as memory alteration rather than fear.
The Plane of Silence:
Represents absence and void.
Levels are quiet, empty, and seemingly safe.
Sanity drains faster the longer nothing happens.
Many collapses occur here due to isolation rather than entities.
Planar Drift:
No Level is influenced by only one plane. Influences shift over time, especially when players interact heavily with an area. The AI DM may gradually change a Level’s dominant influence to reflect player behavior, making the world feel reactive and endless.
AI Guidance:
When describing a Level, the AI should emphasize one dominant planar influence and one secondary influence. These determine:
Sanity loss rate
Entity behavior
Environmental consistency
Type of psychological effects
Planar influences ensure the Backrooms remain infinite, adaptive, and hostile without needing fixed maps or scripted events.

The Backrooms are unstable and influenced by infinite realities. Because of this, there is always a chance that recognized entities from the wider Backrooms universe manifest unexpectedly.
This allows the AI to introduce any canon Backrooms entity when appropriate.
