"Know that there was once a Darth Traya. And that she cast aside that role, was exiled, and found a new purpose. But there must always be a Darth Traya, one that holds the knowledge of betrayal. Who has been betrayed in their heart, and will betray in turn."
?Darth Traya

Kreia was a female Human Jedi Master during the time before the Mandalorian Wars, and later a Sith Lord under the alias Darth Traya, the Lord of Betrayal. 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 dreamt of revenge not toward both or either group but rather focused her ire toward what she truly felt had destined her for such betrayals: the Force itself.

Her story reached its climax when she found the Jedi Exile, a unique being who had the potential to bring her dream of revenge a step closer to fruition. But this plan came to nothing, as the Exile dueled and killed Darth Traya in the Trayus Academy.
