Enoch was a Night Trooper who served as the Captain of the Guard for Grand Admiral Thrawn's forces on Peridea. During the Galactic Civil War's Battle of Lothal between the Rebellion and the Galactic Empire,  Grand Admiral Thrawn's personal Star Destroyer, the Chimaera, was captured by a pod of purrgil summoned by the Jedi Ezra Bridger. Thrawn's forces and Bridger himself were stranded outside the galaxy on the planet Peridea. Enoch served as Captain of the Guard for Thrawn's surviving legion of stormtroopers, commanding his loyal Night Troopers as the Grand Admiral rebuilt the Chimaera and allied with the Dathomiri Great Mothers.
