Mordred was the son of Morgause, a sister of Morgan le Fay who lives on Avalon. In some stories, Morgause is considered to be just another name for Morgan le Fay herself. Mordred's father in some stories is King Lot of Orkney, though in other stories, he is the son of King Arthur, who is a half brother to Morgause and Morgan le Fay. This means that Mordred is either the son or nephew of both Arthur and Morgan le Fay. He is also a cousin of the knight, Sir Gawain. He was born on May Day, and King Arthur was warned that a child born on May Day would bring about Arthur's death.

Mordred eventually became a knight of the round table and was trusted with protecting Camelot when King Arthur travelled across the English Chanel to battle the fictional Emperor of Rome, Lucius. While Arthur was away, Mordred crowned himself king and attempted to marry Queen Guinevere. Arthur was forced to return to Camelot, without his greatest knight, Sir Lancelot, and battled Mordred at the Battle of Camlann. Mordred met him in personal combat, wielding Clarent, a sword stolen from Arthur himself. The two fought fiercely, and Mordred struck Arthur with a wound that would soon kill him, before Arthur fatally wounded Mordred.

Mordred had two sons, the eldest being Melehan. After Arthur's death, the sons were hunted by Arthur's successor, King Constantine III.
