This is the start of a map I did a long time ago with CC2 - it's for an adventure I've always planned to run in a castle, with its supporting village, a little dungeon, some catacombs . . . I keep meaning to go back to this map and finish out the various pieces so I can run the adventure.
The brown bits between the various areas are meant to be paths, though if I have to explain that I haven't really done a very good job portraying them on the map, have I? Now that I look at them with the perspective of time they could be tunnels to someone who doesn't have the picture of the entire setting in their head as I do. The gray parts are catacombs and other subterranean construction to be named later.
The castle is set on a great crag, with the two other areas down the hill from it a bit, if that helps the visualization.
