Gravid was a Sith Lord in the Order of the Sith Lords , which Darth Bane initiated in 1000 BBY . He owned a collection of Sith lore and also possessed the knowledge of essence transfer , which enabled a Force - user to transfer one ' s consciousness into another body . Gravid eventually gained a Twi ' lek female as his Sith apprentice , naming her Darth Gean . He and Gean constructed a fortress on the planet Jaguada . However , Gravid came to believe that absolute commitment to the dark side of the Force would be the Sith Order ' s undoing . He began to incorporate altruism and empathy , which were doctrines of the Jedi — the enemies of the Sith — into his teachings and practices . During that process , Gravid began to lose his sanity and eventually came to the conclusion that the only way the Sith Order would be preserved is that if the Sith teachings , artifacts , and holocrons were either hidden or destroyed . Gravid reasoned that once that was done , he would be able to guide the Sith into what he viewed as a more successful path . At some point around 552 BBY , Gravid used the Force to raise barriers around his fortress and began to destroy all the artifacts , holocrons , and tomes that were in his possession . Gravid was interrupted by his apprentice , Gean , who had penetrated the barriers around the fortress so that she could stop her Master from destroying the Sith ' s resources of knowledge . In the ensuing duel , Gravid managed to severely injure the Twi ' lek by cleaving off one of her arms and shoulders as well as the left side of her face and chest . Eventually , Gean managed to overpower Gravid , killing him despite her being unarmed . Although he was slain , the impact of Gravid ' s actions in destroying the majority of Sith lore would be felt by the Sith Order for generations , hindering the Grand Plan that Darth Bane had initiated to eliminate the Jedi Order and topple the Galactic Republic .
