Roaz

The pagan king of Glois, evil and villainous, who sold his soul to the Devil and was thus able to use sorcery to take over many lands, including the neighboring kingdom of Korntin.

He killed King Lar of Korntin and drove Queen Amene to the border. After holding Korntin for ten years, he was killed in single combat by Wigalois (Gawain’s son), who had arrived as Amene’s champion. Roaz’s wife, Japhite, died from sorrow.
