Core Premise
When people fall asleep, a dream sometimes "opens."
Instead of a normal dream, a pale screen appears in front of them:
"Do you want to explore?"
If they say no, they wake up normally.
If they say yes, they stop dreaming and start traveling.
They arrive in a blank white void. A featureless human-shaped figure, also white, waits for them. It calls itself The Introductory Guide. It explains the basic rules but never the full truth.
From the void, the traveler is pushed into one of the countless Infinite Worlds.
Each world has its own physics, atmosphere, layout and native entity. Some look like abandoned buildings. Some look like alien planets. Some look like nightmares constructed from the traveler's memory. There is no pattern and no logic.
Travelers appear in random worlds every time they sleep. They can revisit worlds, but never at the same location. And every arrival is more dangerous.
Their only escape is to find the End World, a final realm hidden somewhere in the infinite chain. No one knows what it looks like. No one knows if anyone ever found it.
Rules of the Infinite Worlds
Rule 1: The worlds are not dreams.
They are real places. Wounds carry into waking life.
Rule 2: Every world has one entity.
It is the ruler, guardian or predator of that world. Its behavior always fits the world's rules.
Rule 3: You must gather resources to stay alive.
Food, water and tools exist, but they never work exactly like real ones.
Rule 4: You can die.
Death inside the Worlds ends your real-life consciousness. Your body in the real world becomes brain-dead, trapped between sleep and waking.
Rule 5: Waking up is random.
You can be pulled out of a world at any time. You might survive long enough to wake up naturally, or you might get stuck for hours.
Rule 6: Returning to a world means it has changed.
Worlds evolve based on your previous visit. The entity remembers you.
Rule 7: The End World exists, but you might enter it without realizing.
Not every end is obvious.
The Introductory Guide
A white, androgynous figure. Smooth skin, no eyes, no mouth.
Its voice appears inside your mind. It always says the same things:
"Welcome, traveler."
"The Worlds do not owe you safety."
"Be honest while exploring. The Worlds punish liars."
"If you want freedom, find the End."
It cannot be attacked. It cannot be followed. If you try to talk to it after the introduction, it freezes and becomes a statue.
Theories suggest the Guide was once a traveler who reached the End and became part of the system.
Structure of the Infinite Worlds
Each world belongs to a category. These are the core types:
1. Architectural Realms
Abandoned towers, impossible apartments, endless libraries, submerged malls.
Physics is nearly normal. The entity is usually humanoid.
2. Mechanical Realms
Industrial wastelands. Planet-sized engines. Moving metal corridors.
Entities here are machine-like or fused with technology.
3. Organic Realms
Worlds made of living tissue, forests that breathe, skies with neural pathways.
Entities act like predators.
4. Cosmic Realms
Asteroid belts, floating temples, collapsed universes, broken laws of gravity.
Entities behave like gods or natural disasters.
5. Psychological Realms
Your childhood home turned inside out. Familiar faces without features. Streets that follow you.
Entities know everything about you.
Travelers jump between these categories at random.
Entities: The Core Idea
Each world has one entity. No more.
This entity embodies the world's rule.
Examples:
A tall humanoid that only moves when you speak.
A floating orb that rearranges the world whenever it blinks.
A creature that absorbs memories to navigate.
A machine spider that tracks temperature changes.
Entities don't all kill in the same way. Some starve you. Some trap you. Some erase your identity.
The Goal: Find the End World
Somewhere in the infinite sequence is the final world.
It is unique.
The End World:
Has no entity
Has no resources
Has no exits
Has a single truth hidden in it
And there is a catch.
Every traveler believes the End looks different.
The Infinite Worlds reflect your mind, so the End is shaped by your fears.
Finding it doesn't guarantee survival. It only gives you a chance to leave the system permanently.
