An Imperial official oversaw operations on the moon of Cymoon 1, supervising numerous slaves who labored tirelessly to maintain the functionality of Weapons Factory Alpha. Not long after the Battle of Yavin, a group of Rebels infiltrated the facility. Luke Skywalker, a youthful pilot and Jedi in training, discovered the enslaved individuals and prepared to liberate them. The [enslaver](/article/enslaver], having spotted the Rebel protagonist, cautioned him to "step back from the cage unless he'd like to be in one". Skywalker attempted a mind trick to influence the guard, but his lack of mastery resulted only in the slaver becoming confused. The slaver then activated his electro-whip, menacingly stating he would remove Skywalker's "face off." Skywalker responded by activating his lightsaber, evaded the slaver's whip, and severed the guard's hand, causing him to fall to the floor in agony.
