Now with more murder holes! The gray on the above map corresponds to the visible lower level areas (there are still a few missing bits in that layer).
As I said, this is a quick and dirty fill job on the map. Both these layers are currently built out in Inkscape, and the above images were pulled into Gimp for pattern fills and some color work.
