Ghazhak, along with his clan-brother Kohvrekhar, was one of Darth Vader's Noghri bodyguards. After the duel on Cloud City between Vader and Luke Skywalker, the two Noghri were tasked with locating Luke's lost lightsaber and severed hand. After finding both in the possession of a group of Ugnaughts, Vader himself relieved the creatures of their prize and the Noghri accompanied him to Mount Tantiss to deliver the items to Emperor Palpatine.
