Kesin Ommis was a Human male member of the Alliance to Restore the Republic during the Galactic Civil War. A native of the galactic capital planet of Coruscant, Ommis joined the Rebellion about a year after the Battle of Yavin, serving as a skilled gunner on capital ships and starfighters. His longest tenure came aboard the EF76 Nebulon-B escort frigate Tharen before he was assigned to the Alliance High Command's Echo Base on the remote ice planet Hoth. Ommis fought in the Battle of Hoth in 3 ABY as the T-47 airspeeder tailgunner for Rogue Group pilot Derek "Hobbie" Klivian. Ommis was wounded in the battle but survived.
