Darth Gean

"Do you think Gravid's young apprentice was hindered by the prosthesis she was forced to wear after fighting him?"

- Darth Plagueis to Darth Sidious, regarding Darth Gean.

Darth Gean was a Twi'lex female who was apprenticed to the ancient Dark Lord of the Sith, Darth Gravid, as part of the Order of the Sith Lords. Around 552 BBY, Gean learned that Gravid, who attempted to blend the Jedi doctrines with his Sith teachings, was trying to destroy all the various Sith artifacts, tomes, and holocrons that contained Sith teachings. Gean penetrated the Force shields that Gravid had placed around the fortress that they had built together on the planet Jaguada and managed to kill her Sith Master. Nevertheless, during the fight, Gravid grievously injured Gean, which forced her to wear prosthetics. She eventually took an apprentice of her own, continuing the lineage instituted by Darth Bane.
