Modpack The backrooms challenge by neothedoggo

The Backrooms is an urban legend and creepypasta that tells the tale of an endless maze of randomly generated office rooms. It is characterized by the smell of wet carpet, walls with a monochromatic tone of yellow, and buzzing fluorescent lights. Although Internet users have expanded upon this concept by creating different "levels" of the Backrooms, the original version came from a two-paragraph 4chan comment on a post asking for "unsettling images", where an anonymous user invented a story based on one of the photos. The Backrooms drew comparisons to various other horror trends and media, including Minecraft's Herobrine and the concept of liminal spaces. The location is also characterized by "entities", hostile beings created by Internet users
