An infinite hotel themed after the early 20th century, with giant ballrooms, habitable living quarters and a dining area with infinitely respawning food.

(Combined)

negative levels

Level -1 / Glitched Halls

Black and white hallways with doors to rooms of an unsettling nature. Travel through the negative level path is not advised.

Level -2 / Overflow

https://backrooms.fandom.com/wiki/Level_-2

http://backrooms-wiki.wikidot.com/level-minus-2/offset/2

(Influences from both wikis)

Level -3 / Hall of Mirrors

https://backrooms.fandom.com/wiki/Level_-3

http://backrooms-wiki.wikidot.com/level-minus-3

(Influences from both wikis, this one scares me because it involves mirrors in video games)

Level -4 / Null and Void

http://backrooms-wiki.wikidot.com/level-minus-4

https://backrooms.fandom.com/wiki/Level_-4

(I like both of these -4s so I'll probably have the forest one as the main -4 and the carbon tunnels as a sub-level)

Level -5 / Pylon Greyscape

http://backrooms-wiki.wikidot.com/level-minus-5

https://backrooms.fandom.com/wiki/Level_-5

(Again, I like both of these but will probably mix them into a single level with characteristics of both versions)

http://backrooms-wiki.wikidot.com/level-127

(This can be a sub-level because making a weeping human blob monster sounds hilarious)

Level -6 / School Halls

http://backrooms-wiki.wikidot.com/level-52

https://backrooms.fandom.com/wiki/Level_-28

http://backrooms-wiki.wikidot.com/level-117

(I want to do Level 52 and here is an okay place for it. After a certain point the Wikis just have completely different negative levels. And I might as well take a few influences from the other school levels as they are similar.)
