Some kind of bicycle repair shop? Tools, sprockets, grips, all sorts of gear lying on workbenches and on the floor.
Wheels within wheels within wheels, huh?
We’d call this one the second layer, though it’s all relative really.
The floor has a noticeable slope to it, when you drop a gear on the floor you find that it rolls towards a set of two doors with a shopkeeper’s bell hung above them. Curiously both doors open the wrong way for it to be of any use.
The other door is on the opposite side of the room, the debris on the floor seems to have been swept out of the way to make a clear path leading towards it.
