The Backrooms.

NOTE!! i do not know who originally came up with the idea of the Backrooms!!

If your not careful and noclip out if reality in wrong areas, you'll end up in the backrooms, where it's nothing but the stink of moist carpet, the madness of mono-yellow, and endless backround noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in.
