The Backrooms
by Lumaa
The Backrooms adds an unsettling dimension of endless, irregular rooms that players reach by slipping through the edges of reality.
What it does
The mod sends players into a warped space where ordinary rules do not apply. A place that looks familiar on the surface can shift into a maze of office-like corridors, with no clear exits and no fixed layout. Players reach it by moving through a special boundary region, where any location can lead into the Backrooms if the player wanders into the wrong area.
The mod is designed for players who want an uncanny exploration experience rather than a traditional progression path. Its areas stand apart from the Overworld, with stores, houses and parks appearing in forms that defy the normal logic of the world. Every player and the server need a copy of the mod. Installation requires Fabric API and Geckolib, and YetAnotherConfigLib (YACL) is optional. Files are published for Fabric and Quilt across 13 release versions, 1.19 – 26.2, under the MIT License, and the source code is open.
Key features
Irregular office spaces
Endless office-like building layouts that shift in shape, so each route through the Backrooms can differ.

Warped locations can contain boundary regions, and anything that passes through one may lead into the Backrooms.
Warped everyday places
Stores, houses and parks appear in distorted forms that break the normal laws of the world.
Uncanny atmosphere
Areas that look almost familiar but feel different from the Overworld build an eerie tone during exploration.

Who it’s for: Players who enjoy horror-tinged exploration and liminal settings, and server owners who want a shared eerie dimension for their community.
