Are there any fantasy settings that have anything like a god of dungeons? Or anything like a god of caves, or even some eldritch being associated with dungeons? Nearest thing I can think of is Kurtulmak and some other DnD/PF gods associated with mining. I'm making a setting with a living dungeon, and one of the NPCs is a cleric preaching that the dungeon must be given offerings, so I need inspiration for what crazy religion is making him tell the PCs this shit
