Trabier was a male Human who held the position of Head of manufacture for the Sith Empire on the planet of Balmorra during the era known as the Cold War. He possessed a formidable Sith apprentice named Lerek Serrus as his protector, but Serrus was ultimately persuaded to abandon the Sith by a Jedi Consular. The Jedi Consular had come to secure the allegiance of Zenith, a Twi'lek who was unhappy with the Empire's occupation of Balmorra. Subsequently, Trabier was apprehended and imprisoned.
