It's the map from the module located here which is available as a free download and usable as a prelude to A not-free module. So... the premise is an ingredient search which leads to some dwarven ruins which have been inhabited by a Worg, a few various beasties, and the lower levels are inhabited by kobolds. Module 2 in the path is Crown of the Kobold King. The ruins are the last part and have the last ingredient, but are also the most dangerous portion of the adventure. If you have a new group of folks, or just wanna roll some first level 3.5 D20 characters, this'd be a good one to do it. Will be using it as a battlemap in maptool myself. I may post up the other encounters for the module as I get them completed, this one was just the biggest and most difficult, and thus the one I tackle first.
