[Source] Within Korriban's Valley of Golg was the tomb of the Sith King Dathka Graush, wherein the ancient sovereign's sarcophagus was kept. The coffin contained a Sith sword, Dathka Graush's holocron, and the Force-sensitive crystal he once used in place of his heart. In 1 BBY, the tomb was visited by Captain Naz Felyood, who found Dathka Graush's sarcophagus and plundered its contents.
