When he was younger he commanded an army and became the King of Nemeth. At some point in his life Rodor had a daughter, Mithian (presumably with his wife). Many years later, in an effort to settle a land dispute between Camelot and Nemeth, Rodor arranged for his daughter to marry King Arthur Pendragon. However, the engagement was short lived as Arthur could not forget his old love, Guinevere. Mithian returned home after agreeing to an arrangement on her Kingdoms (and her fathers) behalf to receive all the disputed Lands of Gedref as recompense.
