The Khazard launderer is a follower of Khazard found in the laundry building which is directly west of the Fight Arena. He has a minor role in the While Guthix Sleeps quest. Players must either charm him with a Ring of Charos (a) or pay 5,000 coins to receive Movario's dirty laundry. After the quest, he will give it to you for free, even without the Ring of Charos.
