Kei Loo Bross was a Jedi Master who most likely existed during the era of the New Sith Wars.
At one point, Master Bross apprehended a Sith warrior who shared a bond with the Sith battlelord named Farh j'Hien. This warrior, experiencing severe agony due to his distance from his Battlelord, attempted to request assistance from Bross. Communication proved challenging as Master Bross was not acquainted with certain terms used by the warrior. Employing the Force, Master Bross perceived the link between the warrior and his Lord, realizing that any warrior distanced from their Sith Battlelord would endure suffering. He failed to recognize that the remaining warriors would also experience pain as a result of the deserter, which fueled their determination to locate him.
