Nice idea for a map. We were discussing doing a dwarven cave system as a challenge once. I cant remember if we ever done it or not. Anyway I just piped up to say there is a keyword index in my sig and is also on the forum quick links on the menus at the top so maybe you can check out cave and see what turns up there. In a lack of foresight, we didnt tag all of the finished map images with their content so you have to page through all the thumbnails and see what might be a dwarven cave system. If you like I can make a special run on it to see if it will pull up dwarven stuff but you can use the advanced search to do much the same thing so if that drew a blank then its not likely the keyword search scraper will either.
