this Imperial Commander was in charge of construction on a new wing of the Imperial Hall of Heroes when Han Solo was sent to assist him. Nyklas had been using - and mistreating - a group of Wookiee slaves he had obtained from the Trandoshan slaver Ssoh. During a mission to obtain more Wookiees, Nyklas found that his contact's ship was disabled. He ordered Han and his flight of TIE Fighters to take out the ship, but Han discovered that there were Wookiees still alive on board. Nyklas ordered Han to kill the survivors, but Han rebelled against this senseless slaughter. He freed one of the Wookiees, named Chewbacca, and was immediately reprimanded by Nyklas. Han was quickly given a dishonorable discharge and blacklisted as a pilot.
