Underdark Dungeons

From the publisher's website A Web Enhancement for the Forgotten Realms Underdark Accessory The Underdark is a vast place, filled with fiendish challenges both natural and contrived. The various inhabited and wilderness areas feature many locations in which adventures can be staged, but several sites are of particular note. Some of the sites below are merely adventure hooks that you can develop as you see fit. The Partially Keyed Dungeons section features two more developed areas that correspond to the maps included with this web enhancement.
