Lopin was the servant of Nalesean Aldiaya.
He had dark skin, a fat gut, and was balding. He had a blocky face, was stout, and had a beard that nearly reached his chest.
He was always complaining about Talmanes Delovinde's servant Nerim. He was with the Redarms when they traveled to Ebou Dar. After Nalesean's death, Matrim Cauthon took Lopin to be his servant along with Nerim.
He then stayed in the Tarasin Palace with Mat and began to transfer Mat's clothes and all his money back into the Wandering Woman. Mat sent Lopin and Nerim to collect all the stored money and meet him outside the city when Mat carried out his plan of escaping with the captive Aes Sedai.
He then caught up with Mat and traveled in Valan Luca's Traveling Show as cover for their escape.
