Phenter was a Human male who held the rank of Captain within the ranks of the Sith Empire after its reformation, and he lived during the era of the Galactic War.
During the Cleansing of Nopsin, Phenter served under the command of General Greist, working alongside Lieutenant Pierce. Despite Pierce's presence, it was Phenter who received a promotion to captain from the general, a choice Pierce agreed with. In 3961 BBY, Darth Baras commanded Greist, Phenter, and their troops to leave the Battle of Corellia and head for Hoth. However, Servant One intervened, recognizing that the Sith Lord's intentions were not aligned with the Sith Empire's goals, and instructed the Emperor's Wrath to order the soldiers to return to Corellia. Faced with conflicting orders from a member of the Dark Council and the Emperor himself, Phenter and Greist chose to disregard Hoth and proceeded to Corellia.
