The Night Troopers were stormtroopers who served Grand Admiral "Thrawn" during his exile on the extragalactic planet Peridea, comprising the majority of his forces. They were stationed aboard the Imperial I-class Star Destroyer Chimaera under the command of Captain of the Guard Enoch following the Battle of Lothal in 1 BBY, where Thrawn's Star Destroyer had been taken by the intergalactic-traveling purrgil at the request of the Jedi Ezra Bridger.
