Dathka Graush
this ancient Sith Lord was buried on the planet Korriban some 7,000 years before the Battle of Yavin. A pureblooded Sith, Graush was one of the most powerful warlords of his time. He rose to power on Korriban by gathering his forces and destroying his enemies, then tried to make himself immortal by creating the unusual jewel known as the Heart of Graush. He thought that, by removing his physical heart and replacing it with a Dark Side jewel imbued with Sith spirits, he wouuld live forever. However, Graush was killed by enemy assassins, and was buried in the Valley of Golg, on Korriban. The Heart of Graush was buried with him, waiting for an unsuspecting being to touch it. This contact would allow the jewel to possess the being, eventually transferring their spirit to Graush and giving him new life. Graush nearly returned to life during the height of the New Order, when the crew of the Jynni's Virtue stumbled upon his tomb. Captain Naz Feylood touched the Heart of Graush and unleashed the spirit, but the Heart was lost in the destruction of the pirate ship.
