Barsen'thor was a ceremonial rank in the Jedi Order that originated as a Cerean word meaning "Warden of the Order."
First bestowed posthumously upon Padawan Lorjan Sakku by his Master before he defeated his own brother Lyhesh and redeemed him at the cost of his own life, the title was adopted by the Order and given only to exceptional Jedi. By the time of the Cold War, only one other individual had been given the title, and the apprentice of Jedi Master Yuon Par was named the Barsen'thor after the defeat and redemption of the Sith Lord Vivicar.
