Here’s another map. This one features a small dungeon that local cultists have used as a meeting place for their rituals. It has also two hidden entrances: one via a secret door (marked with an S) and another through a small underground pond. The main chamber opens to a cliff and sometimes sacrifices are made by forcing people to jump of the planks extending over the edge. The cave is often deserted unless a ritual night is at hand. Again, this one would also favor lower level play.
The likely location to find this dungeon would be nearby a small town or a village where most of the villagers take part in a murderous cult in exchange for protection and favors. They could worship either a genuinely powerful entity or a weaker spirit that has, for example, minor healing powers.
