The seneschal of King Leodegan of Carmelide (Leodegrance).
He was married to a beautiful woman who Leodegan coveted for his own. One night, Leodegan raped Cleodalis’s wife, begetting a daughter later known as the False Guinevere (‘Genievre’). Leodegan then locked Cleodalis’s wife in a tower and kept her as a concubine for several years. Cleodalis, however, never stopped serving the king faithfully.
