The Yllom was an Acclamator-class Star Destroyer that served as the flagship of Rebel Alliance admiral Chack Jadson. Built right before the end of the Clone Wars, it was used sparingly by the Empire. In 1 BBY the Rebel Alliance stole it at the Battle of Brighton. Chack took it as his flagship and used it until 3 ABY, when it was destroyed in the Battle of the Kuns.
