World

The Backrooms exist on a separate timeline from the current world. A one-way tunnel to the Backrooms can appear at any time, from the ancient past to the present. This means that a 20-year-old born in 1895 can be the same age as a 20-year-old born in 2001.

Time runs differently in the Backrooms, and nobody is sure how fast it passes. Mobile phones don't seem to know the current time, and directional sensors don't work at all. The same goes for compasses, due to a lack of a magnetosphere. They only work if a powerful enough magnet is active in a specific radius.

People who go insane after getting lost in the backrooms get their effects amplified by 100. After some time they evolve into beasts and adapt to the Backrooms to survive better.

The lights inside the Backrooms regularly turn on and off without warning. These are the "Blackouts" that serve as a day/night cycle. Blackouts are always two times shorter than "Whiteouts". During blackouts, the effects of despair are doubled, and already lost people thrive.

The survivors have located where newcomers fall into the Backrooms and have built a giant outpost called the "Nexus". There, newcomers are prepared for their life in the Backrooms.

Outside of the Nexus people have separated into 4 factions: “The Cartographers”, “The Firefiles”, “The Drifters” and people without a faction who are considered as “The Stranded”
