First Zerek was a member of the Dark Vanguard. Though a junior member of the First Rank, he was skillful enough with a lightsaber and the dark side to be one of Valin Aresh's bodyguards. He accompanied Aresh to the Redeemer in 1,384 BBY, remaining at his master's side as Supreme Modality technicians labored to get the ship operational. When Elata Cazars and Zaella Sabir infiltrated the ship, First Zerek was the first to challenge Cazars, but she killed him after a short duel.
