The Lost Mine of the Numminen clan is no more than three days east of Threshold on the Dwarf Road, but few have visited it since the Dragon swept over the Black Peaks. Many believe that the clan was executed by the Dragon Army, but this was never confirmed.
Other dwarves tried to convince the Numminen to flee the onslaught of Goblinkind, but they refused. The Witch-Queen even sent a delegation, begging them to abandon their mine before it was too late. Neither the Elves or the Numminen were seen again.
Mikko the Dwarven Hero, a distant relative, is in Threshold looking for adventurers to explore the Lost Mine and bring news of the fate of his ancestors.
