( I make a lot of things for my campaign which will never be for sale, because they're made out of online OSR resources. This one was constructed without moving from my couch with maps from Donjon (sorry Dave's Mapper, Donjon has room numbers) and stocked using only the Dungeon Dozen, Abulafia, Tarsos Theorem and this. Hyperlinks just go to the source generators.)
