Constantine III of Britain
King Arthur’s cousin and successor as king of the Britons. He was the son of Cador of Cornwall, a relative of Arthurs. Constantine fought in the Battle of Camlann and was apparently one of the few survivors. Arthur, about to be taken to Avalon, passed the crown to him.
Constantine continued to have trouble from the Saxons and from the two sons of Mordred. He eventually subdued his enemies then having sworn to make peace, disguised himself as an abbot, entered the church where two youths had sought sanctuary and murdered Mordred’s sons on the steps of the altar. He was struck down by the Gods for killing them while in sanctuary, and was buried next to Uther Pendragon at Stonehenge.
