Thanks for reminding me about this fellow NeonKnight. Although its been several years now since he's updated, I was always impressed by his handdrawn and digital maps.
The Rel Astra map is from his Rel Astra Campaign website at http://mywebpages.comcast.net/jerryleh/. What really blew me away though was Boslok's earlier Irongate campaign at http://mywebpages.comcast.net/jlehman51/. Once you enter, click on the "adventures" tab to read session summaries of a group he dm'ed. Each session has its own handdrawn map and I especially liked the Celestian Towers map as well as the maps of the places that the magic paintings that were the centerpoint of the campaign linked to. I wish he were still updating, good luck inviting him to the board. (Tried contacting him a long time ago, but he was mia.)
