Trevin was a male Human Moff and, hence, a member of the Moff Council. When the Jedi Order established a new government on Coruscant, Trevin and a group of rebellious Moffs supported the deposed Chief of State Daala's campaign to usurp control of the Imperial Remnant from Head of State Jagged Fel. During the Battle over Exodo II, Trevin was killed in the destruction of his flagship.
