King of the Ille Estrange.
Vagor's son, Marabron, charged Sir Lionel with treason. The wife of Marabron's brother had played on Lionel the same sort of trick Potiphar's wife played on Joseph, forcing Lionel to kill the husband in self-defence.
King Vagor held Lionel prisoner in his castle. Lancelot arrived and championed Lionel, fighting Marabron and forcing him to retract the charge.
