Gray Halls

[Inspired by the Backrooms; Liminal Domain series entry 5] Updated: Unlike the previous four domains, this one is finite in a sense, each labyrinth of pristine gray marble halls and chambers stretching only a few square kilometers. However, there are a seemingly endless amount of upper and lower levels, all bearing a different layout from each other. This leaves the assumption that the domain is a tower of sorts. But don't try finding the top or bottom. There ain't any. [again, don't mind the voice]
