Dramath's holocron

Dramath's holocron was used by Sith Lord Tenebrae to imprison the spirit of his father Dramath. After Tenebrae killed his father in 5103 BBY, he imprisoned his spirit in the holocron, so he could continue to torment him. A few years later he performed the Ritual of Nathema, wiping out all life on the planet and achieving immortality. Tenebrae, now called Vitiate, kept the holocron in his personal vault in the Sanitarium, the only structure that remained standing on Nathema over time.

Imprisoned and tormented for over a millenia, Dramath eventually learned that the holocron could serve as prison for not just him, but Vitiate as well, and even destroy him under right circumstances. In 3631 BBY his holocron was found in the Sanitarium by Lana Beniko and the Alliance Commander, who by then housed the spirit of Vitiate in his head. Heeding Dramath's council, they released his spirit and took the holocron with them in the hope of destroying the Immortal Emperor once and for all.
