By the year 533 BBY, Darth Gravid, the Dark Lord of the Sith, along with his Twi'lek Sith apprentice, Darth Gean, possessed a stronghold located on the planet known as Jaguada.
Gravid began to descend into madness as he developed the conviction that the Sith ought to integrate Jedi doctrines with their own. His efforts to do so contributed to his increasing instability.
Sometime around 533 BBY, Gravid, having decided that his collection of Sith holocrons and ancient texts had to be eliminated for him to reconstruct the Sith Order, employed the Force to generate defensive shields encompassing his stronghold. He then commenced the destruction of the Sith knowledge he possessed, including any record of the transfer essence technique.
Gean managed to penetrate the protective shields surrounding the stronghold and engaged her Master in a battle. During their conflict, Gravid inflicted severe wounds upon Gean, severing one of her arms along with her shoulder and the left portion of her face and chest. Nevertheless, despite being without a weapon, Gean ultimately prevailed, ending the life of Gravid.
