Where Marly lives
It's a ceiling crawlspace, so not much headroom. It's also obviously much darker and dirtier and such.
The ceiling is mostly just exposed, unfinished wood and fiberglass insulation. The floor is splintery, and has support beams running horizontally across it, so the floor is broken up into sections. On the walls and ceiling are air ducts, pipes, and electrical wires.
Covering the walls are posters, mostly with pretty women on them, but also posters for art shows and theater productions. I didn't show it here, but they're mostly torn and dirty, since she either salvages from garbage cans or tears them from the walls.
To the far left is a pile of pillows and cushions, from old theater seats to actual bed pillows. They're beat up too, and there's some white smears of plastery stuff on them.
She has a phonograph for listening to records, next to a collection of masks. She wears all of them, changing them like you'd change outfits. This is next to the hole in the ceiling where she accesses her little home.
There's a bucket catching water from a leaking pipe, next to a pile of the plaster powder. There's also white paints and makeups but I didn't add them.
Not shown is lighting (I'm thinking maybe just a lamp or old Christmas lights), an area for supplies and canned food, her records, and books and ticket stubs and junk like that.
For bathrooms she just uses one of the many ones in Fort Frolic. She's usually wandering around anyway.
