The backrooms

If you're not careful and you noclip out of reality in the wrong areas, you'll end up in the backrooms. Here, it is nothing but the stink of old, moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz,and many miles of randomly segmented empty rooms to be trapped in God save you if you hear something wandering around, because it sure as hell has heard you.
