The fabled mines of Dhol Kuldhir once showered the Dalelands, Cormyr, and points beyond with precious gems and expertly crafted jewels. Operating from a hidden complex in the Thunder Peaks, their exquisite craftsmanship was said to rival that of even Thunderholme. Almost as quickly as it rose to prominence it vanished, along with all of the dwarven miners, crafters, and untold riches. Some speculate that the mine ran dry, and the inhabitants abandoned it for a more plentiful location. Others believe that they probably fell victim to one of the many goblin tribes plaguing the area. The truth, however, is much more grave. Centuries later, the nearby town of Keen is beset upon by unlikely thieves, the local innkeeper charges a small band of unlikely allies to investigate the string of burglaries. What they uncover leads them to the long-lost dwarven mine. In the darkness, they will have to brave insidious traps, cunning monsters, and the dreaded new lord of Dhol Kuldhir.
