Sith Herren ifråga var Darth Pregnant .
A human Sith Lord whose short reign had elapsed some five centuries earlier, Gravid had been persuaded to believe that total commitment to the dark side would sentence the Sith Order to eventual defeat, and so had sought to introduce Jedi selflessness and compassion into his teachings and practice, forgetting that there can be no return to the light for an adept who has entered the dark wood; that the dark side will not surrender one to whom, by mutual agreement, it has staked a claim. Driven increasingly mad by his attempts to straddle the two realms, Gravid became convinced that the only way to safeguard the future of the Sith was to hide or destroy the lore that had been amassed through the generations—the texts, holocrons, and treatises—so that the Sith could fashion a new beginning for themselves that would guarantee success.
Ett senare citat bekräftar att Sith Lords (före Gravid) rutinmässigt hade kunskap om hur man fyller i en " essensöverföring ";
Darth Bane had referred to sorcery as one of the purest expressions of the dark side of the Force, and yet he hadn’t been able to harness those energies with near the skill as had his onetime apprentice Zannah. Bane’s disciples, however, believed that he had experimented with a technique of even greater significance: that of essence transfer, which he had learned after acquiring and plundering the holocron of Darth Andeddu, and which involved the relocation of an individual’s consciousness into another body or, in some cases, a talisman, temple, or sarcophagus. Thus had the most powerful of the ancient Sith Lords survived death to haunt and harass those who would infiltrate their tombs.
