Another very cool map from Mr Roberts.
I use his maps in their jpegs or maptool campaign files versions for my own adventures, "build" with the VTT MapTool.
And one thing I like about this one is that it can be seen as as ruined public place (with a volcano nearby ;) ), an arena, the entry hall of a devilish palace in one of the nine hells etc.
Glyphs and trees are objects can be removed or used elsewhere thus giving you a very valuable product.
