"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

Darth Traya is a fictional character from the Star Wars game Knights of the Old Republic II. Darth Traya is the name that the Force-witch Kreia took after she was exiled from the Jedi Order and became a Sith Lord, one of the three the title of the game refers to. She had also taught Darth Revan in the Jedi ways when she was still a Jedi Master. Kreia was consumed by guilt after the Jedi Civil War, wondering if her teachings had led to Revan's fall. She travelled to Malachor V, which she sensed as Revan's last location and, corrupted by the dark side, embraced the secrets of the Sith (LucasArts KOTOR Chronicles).

Darth Traya discovered an academy on Malachor V known as the Trayus Academy. The academy was apparently an ancient Sith ruin, so it is unknown if Traya named the academy after herself, or herself after the academy. It is quite possible that the existence of this structure might have been why the Mandalorians treated Malachor V with religious reverence.

Among her students were Darth Nihilus and Darth Sion. Even when she was a Sith, Traya had some notion that neither the light nor dark side of the Force was superior to the other. Because her teachings incorporated light side concepts (she never believed in power or destruction for its own sake), Sion and Nihilus grew weary of her. They betrayed her, but she either escaped or was allowed to live.

Darth Traya had the (possibly unique) ability to wield three or more lightsabers in combat, holding each of them aloft with the Force and having them fight with a will of their own.

Traya's eyes appear badly damaged but later are revealed to have simply atrophied from dis-use. It was within her Force power's ability to have repaired her eyesight but she refused to do so, having a superior ability to "see" through the Force and regarding her natural sight as a distraction.

On a final note, it was found she had many detailed glimpses into the future, some even spanning to the fall of the Republic nearly 4,000 years later. Her clairvoyance was even so specific that she was able to predict the existence and death of Jango Fett. Shortly before her death, one of her predictions regarding the Mandalorians went as follows: "They will die a death that will last millennia, until all that remains is their code, their history, and, in the end, the shell of their armor upon the shell of a man, too easily slain by Jedi." This references both the fact that Jango wore Mandalorian body armor and his defeat on Geonosis (shown in Attack of the Clones).

Like Sidious and Vader, Darth Traya's name suggests another word: betrayal.
