Treibeiu was a Human female Jedi Knight who served the Jedi Order during the Clone Wars. Treibeiu was stationed at the Almas Academy, a Jedi academy located on the planet Almas, and, in about 20 BBY, in the aftermath of an incursion made by the Chevin slaver Phylus Mon into a Sith fortress situated on Almas, Treibeiu discovered the dismembered corpses of three Jedi whom Mon had slain. Treibeiu subsequently helped to oversee a search effort to locate the missing Jedi Constanten, Valiri, and Vorlocca, and she briefed a band of freelance agents who had been assigned to look for the Jedi inside the fortress.
