The Kragor Mines

From publisher blurb: A legendary dwarven hero leads a hearty group of dwarven miners working on a new mine for valuable ore. After the entire mining camp did not return to their homes, the dwarven village has sent a tough dwarven hunting party to investigate the disappearances. They too have vanished without a trace. The desperate dwarven villagers ask the party to investigate the missing dwarves. If you like deadly Drow, Dark Stalkers, and other cavern crawlers, this adventure is just right for you!
