Within the Valley of Golg on Korriban resided the tomb of Dathka Graush, an ancient Sith King; the sarcophagus of this long-dead ruler was housed inside. This coffin held a Sith sword, along with Dathka Graush's holocron, and the Force-sensitive crystal that once served as his heart. Naz Felyood, a Captain, came to the tomb in 1 BBY, discovered the sarcophagus, and proceeded to loot the items within.
