When the platinum mines of the small dwarven outpost known as Tar Urkatka played out, the dwarves who worked there vacated the area. The mines and dwarven ruins left behind gained the name Zolurket, Keleshite for “Dark Death.” The few brave explorers to venture to Zolurket and return report that most of the mines remain intact and are haunted. Stories differ, though, as to the nature of the haunting. Some claim ghosts of dead miners, others a burial ground uncovered by mining, and at least a couple report a lich infestation. Other rumors also whisper that the mine isn’t played out at all, and that the dwarves left for some other reason.
