Darth Traya was a Human female who had served as a Jedi Master named Arren Kae during the years prior to the outbreak of the Mandalorian Wars, and later a Sith Lord known as the Lord of Betrayal. She was the mother of Lucien Draay, who was later known as Darth Sion. Later in life, after she turned to the dark side, the traits that she had exhibited in her former profession suited her new role as master schemer and Sith Lord. Having been betrayed by both the Jedi and the Sith, she dreamed of exacting her revenge—not toward both or either group, however—but rather against what she truly felt had destined her for such betrayals: the Force itself.
