The Backrooms
by SeaSharpy
The Backrooms adds a custom dimension of endless yellow rooms, reached from a yellow carpet block with an ender pearl.
What it does
Players enter the Backrooms dimension by throwing an ender pearl at a yellow carpet block and then right-clicking it. Inside, the dimension is built from several zones with different biomes: one based on wood, one on stone, and a bed-themed area. Each zone uses its own block palette, such as stripped birch and sandstone in the normal zone, stripped acacia and sandstone in the red zone, and oak planks with redstone lamps and levers in the wood zone.
Loot is spread through the dimension in barrels, which hold enchanted books at higher levels than usually appear in the world. The mod also adds knockback sticks to the loot pool. Only the server needs The Backrooms installed; players join without installing it unless they want to play single-player. Fabric API is required, and the mod is published for Fabric only, for game versions 1.21.4 – 1.21.8, under All rights reserved.

How it compares
Backrooms: Kepler runs on Fabric, Forge and NeoForge for 1.21.5, under the MIT License, and only the server needs it. Backrooms Bounded is open source under the MIT License, runs on client and server for 1.21.1, and needs both sides to have it. Backrooms Through The Walls is a client and server mod for Fabric 1.21.1, released under All rights reserved.
