First Appearance: Knights of the Old Republic II: The Sith Lords
While plenty of Dark Side villains are adept at manipulating their enemiesâand their alliesâone of the most accomplished at this is Darth Traya from Knights of the Old Republic II. Setting herself up as a mentor to the Jedi Exile, who is regaining her Force abilities despite having been cut off from the Force by the Jedi Council, Darth Traya moves the Exile around like a piece on a chess board, maneuvering the Exile into revealing the locations of hidden Jedi Masters so that Darth Traya can murder them. The Exileâs mentor and companion thus becomes the final enemy the Exile must defeat.
