Darves Hill is a megadungeon roughly 5 hexes north of the town of Namh. It is a big hill, with a bunch of ruined buildings on the surface, and 9 (or more) levels underneath.
The maps are pretty basic, having been drawn with pen on large graph paper with small squares.
I'm populating the dungeon as they go, but I have some big ideas on the back burners that I will slowly start to hint at while they adventure.
Here's the maps:
