I have been trying to find maps of building interiors that look like the buildings have fallen down, and you are actually walking on the walls, with the former floor on one side and ceiling on the other. i can't seem to find anything like this. Specifically stone or modern or some non wood material. (For those familiar with the pathfinder world of Golarion, I'm taking my players through a ruined fallen city of the Shory, because these used to be flying cities, most buildings would not have survived the crash standing up ) failing that, any ideas on how to build a map like this? I guess many trapdoors or just holes in the floors, and the doorways players walk through would be more like holes in the wall. But how would I represent that? Or hour to show a hole in the ceiling?
