le Serpelions
A British earl who invaded the lands of Degrevant, a Knight of the Round Table.
Degrevant, away on the Crusades, learned of the earl’s ravagings and returned to meet him in battle. The earl lost the war. Sere’s daughter, Melidor, fell in love with Degrevant and began a secret romance. Sere discovered it and tried to ambush Degrevant, but only succeeded in getting many of his knights (including his steward Aymere) killed.
Persuaded by his wife and daughter, he reconciled with Degrevant and allowed him to marry Melidor.
