Metwyn is a slender man with a pale face and boyish looks, though he is actually in his mid thirties. He was born in Cairhien and is known as the best swordsman among these men.
In Ebou Dar he is one of the few Redarms to survive the gholam attack looking for the Bowl of the Winds. He then stays in the Tarasin Palace with the rest of the surviving Redarms. Mat sends him to meet him outside the city when Mat carries out his plan of escaping with the captive Aes Sedai.
He meets up with Mat again outside Ebou Dar and joins Valan Luca's Traveling Circus with the rest of Mat's group. He is part of the group that chase Renna Emain after she stabbed Egeanin Tamarath and tries to flee to the town of Coramen.
