Sarkil, designated C-2223, was a Human male Senior Lieutenant that was in the Imperial Army unit, the Imperial Storm Commando Corps, and was born on Vulpter. He stayed out of battles because he was better stealth, and, along with a a fellow commando, was sent on secret missions by Darth Vader that even the Emperor didn't know about. Later on, the two were stationed on board the Executor, Darth Vader's flagship. During the battle of Rehn Var, a Rebel spy sneaked on board the ship, and the duo hunted him down, but he jumped down a garbage shoot and was later killed by the two closing walls.
