Teprimal served in the New Republic as a captain and a starfighter trainer, stationed on the Nebulon-B Frigate known as the Tedevium. He collaborated with Colonel Atton Repness, participating in Repness's illicit black-market operation. Lara Notsil documented a discussion between Repness and Teprimal concerning the unlawful acquisition and later transaction of an A-wing starfighter. When Notsil covertly transmitted the details to Director of New Republic Intelligence Airen Cracken, both Teprimal and Repness were revealed.
