Circa 552 BBY, the Dark Lord of the Sith Darth Gravid and his Twi'lek apprentice Darth Gean owned a fortress on the planet of Jaguada.

In 552 BBY, Gravid had destroyed all traces of the essence transfer ability. He believed that the Sith should merge Jedi teachings with that of their own. His apprentice did not share his visions for the future of the Sith, so she penetrated the defenses of the fortress and killed Gravid.
