There are two circular shafts carved into the rock. The one on the left provides access towards higher levels, and both also lead deeper into lower levels. The entire level is carved into dense, heavy rock with all kinds of striations and figures in the exposed stone. The ceilings are arched vaults and domes, and the walls are even and regular, without any cracks or seams, except at the floor. Underfoot is an incongruous floor of fitted and tightly bedded pavers that fill this dungeon. Doors are stout oak set into mortised recesses and swinging on hidden, pivoting hinge pins set in the floor and the header of each opening.
This map is more about graphic experimentation than the story and rationale for the dungeon itself. The scan is grayscale, so that the pencil for the floor pattern would stay lighter. Background pattern is from a whole selection of texture patterns I found recently that I’m trying for alternative hatches. Everything is hand drawn, but it might work better if it was a pattern dropped into the background.
