Trezza, a Falleen male, held the position of headmaster at the Orsis Academy. This Falleen, exceeding two centuries in age, maintained a positive relationship with Palpatine who was in disguise. He professed a lack of fondness for the Jedi and refrained from excessive questioning when a young Maul was enrolled. During that enrollment, Trezza once intervened to prevent Meltch Krakko from shooting the young boy. Possessing the ability to sense the Force in use, the Falleen correctly identified Maul as Force-sensitive. Following Krakko's unsuccessful attempt to eliminate Maul, Sidious commanded Maul to execute everyone at the academy. Trezza's attempt to assassinate Maul by hurling a knife was thwarted when Maul, using his Force-augmented reflexes, caught the knife and retaliated by throwing it back, resulting in Trezza's death.
