Hallaf was a smuggler of the male Human species, and the proprietor of the Meliflar Station. Following Abeloth's arrival at the station, and the subsequent infection of his daughter, Fala, his crew, under the leadership of Cardya, started a mutiny against him. He, along with his daughter, was imprisoned in the brig. It was there that the Jedi Grand Master Luke Skywalker, his offspring, Ben, and the Sith apprentice Vestara Khai discovered them. He implored the Jedi to provide assistance to his daughter and furnished them with the access codes for his station. Once Master Skywalker had cured Fala, he expressed his gratitude for Hallaf's assistance and for refraining from informing law enforcement about their presence.
