Lord of Estremors, brother of Maduc, and uncle of Plarés. He was called the Green Knight. Raolais was an enemy of Arthur and, consequently, Arthur invaded his lands. Plarés was killed in the fighting. The war was eventually decided in a single combat between Raolais and Gawain. Gawain was victorious, and Raolais became a Knight of the Round Table, joining Arthur’s war against the Saxons. Maduc, disgusted with Raolais’s fealty to Arthur, became hostile to his brother.
