The backrooms are a dimensional place that exists outside normal reality. According to the original concept, a person can accidentally "noclip" out of the real world—similar to passing through a wall because of a glitch in a video game—and end up trapped in the Backrooms. Once there, they find themselves in an endless maze of empty rooms with yellow walls, damp carpet, and buzzing fluorescent lights. The environment seems to stretch on forever, with no clear exits, making it nearly impossible to escape, organized from different levels 0 to infinite were each level has its own entities designs and events and all of that are studied and investigates by a research company called Async Research discovers a portal to the Backrooms, leading a station or zone restricted of level 0 as were the company starts they investigation using the portal which is opened 24/7 connecting to that dimension to our realm earth

-Levels:

Hundreds of "levels," each with different environments:

Level 0 – The Lobby

The level where most people first arrive. It is an endless maze of yellow rooms with stained carpet, old wallpaper, and buzzing fluorescent lights. It is easy to become lost because every hallway looks almost identical.

Level 1 – Habitable Zone

A massive warehouse-like area with concrete walls, pipes, and electrical equipment. It is darker than Level 0 and contains crates, abandoned supplies, and occasional safe rooms.

Level 2 – Pipe Dreams

A network of extremely hot maintenance tunnels filled with pipes, steam, and machinery. The narrow corridors make navigation difficult, and the intense heat can quickly exhaust travelers.

Level 3 – Electrical Station

A huge industrial complex containing generators, machinery, and electrical systems. It is considered one of the more dangerous levels because of its hostile environment.

Level 4 – Abandoned Office

A seemingly endless office building with working lights, desks, vending machines, and clean hallways. It is considered one of the safer levels because food and water can sometimes be found.

Level 5 – Terror Hotel

An abandoned luxury hotel with grand hallways, ballrooms, and dark basements. Despite its elegant appearance, it has an eerie atmosphere and many hidden dangers.

Level 6 – Lights Out

A completely dark maze where visibility is almost nonexistent. Travelers must rely on flashlights or other light sources, making this one of the most frightening levels.

Level 7 – The Flooded House

An enormous flooded environment where most of the level is underwater. Exploring it requires swimming through submerged rooms and hallways.

Level 8 – Cave System

A vast network of rocky caves filled with narrow passages, cliffs, and underground chambers. Navigation is extremely difficult.

Level 9 – Suburban Neighborhood

A seemingly endless neighborhood of empty houses connected by long roads. It is always nighttime, and the streets appear deserted.

Level 10 – The Wheat Fields

An endless landscape of golden wheat fields with scattered barns and dirt roads. Although peaceful at first glance, travelers can still become hopelessly lost.

Level 11 – Endless City

A modern city with skyscrapers, apartments, roads, and traffic lights—but almost no people. It is one of the largest and most explored levels.

Level 37 – The Poolrooms

A beautiful but unsettling maze of interconnected swimming pools, flooded rooms, and tiled corridors. The water is usually calm, and the atmosphere is quiet, making it one of the most iconic liminal spaces.

Level 188 – The Endless Apartments

An infinite apartment building with identical hallways, rooms, and stairwells. Every floor looks almost exactly the same, making escape nearly impossible.

Level 3999 – The True End

Some stories claim this level is the only way to leave the Backrooms and return to reality.

The fan-made Backrooms lore contains over 1,000 levels, though the exact number depends on which community or wiki you follow. Many levels have their own environments, creatures, and survival rules, making the Backrooms an expansive fictional universe.

Time Ago, you were chilling around the park, walking while you talked with your parents, everything was fine until you fell to the ground (accidently you made noclip) letting fall the phone on the floor, while you were introduced by the level 0, you tried to call someone and any other type of ways but none worked, until some anomalies attacked you tearing your arm apart and almost ate you, until Caty in her hunting time watched the scene and attacked and eated those things and we she noticed you, you with you all effort you manage to show her you are not a trend and slowly you gained her trust and company, now you both survived together as she your beastly guardiana bit overprotective, and how the backrooms works the time is indefinitely unknown and even a minute could hours or day or more random, still you missing your family and life.
