Xat Hracken was a male Human Sith Lord who served as the Combat Master at a Sith academy on Odacer-Faustin. By 3645 BBY, Hracken had taught at the academy for many decades. A short time after the disappearance of the student Wim Nickter from the academy, Hracken stayed up late one night with the student Mnah Ra'at, while Ra'at practiced on the academy's combat simulator. Hracken turned off the lights in the room to test whether Ra'at could face the machine while blind.
