Heart of Graush
this immense jewel was imbued with the Dark Side of the Force by Dathka Graush more than 7,000 years before the Battle of Yavin. Graush removed his own heart and replaced it with the jewel, hoping to keep himself alive forever. It was believed that the jewel contained over a thousand Sith spirits, but it didn't prevent Graush's inevitable death. The Heart of Graush was buried with him in his tomb on Korriban, where it waited for another being to touch it. The Heart would then take possession of their spirit, giving Graush momentary life. As long as the Heart remained in contact with the being, Graush could regenerate. The Heart was found by Naz Felyood, captain of the Jynni's Virtue, during the height of the New Order. The ship had crash-landed on Korriban after escaping an Imperial boarding party, and Felyood set out to scout their location. He stumbled into Graush's tomb and tried to take the Heart, inviting the possession of the Sith spirit and unleashing the Korriban Zombies. However, the Heart was lost when Babbnod Luroon destroyed the Jynni's Virtue, and Captain Felyood was doomed to wander Korriban forever as an undead being, searching in vain for the Heart of Graush. The logs of the Jynni's Virtue were later found by Jedi historians during the early years of the New Republic, locked inside Dathka Graush's tomb, which apparently had been unopened for 7,000 years. Recordings indicated that the Heart was taken by one of the Korriban Zombies, but may have been destroyed in the explosion of the Jynni's Virtue.
