Sir Yvain

Sir Owain, also called Sir Yvain and the Knight of the Lion, was a knight in Arthurian Legend. Son of King Uriens of Rheged, and supposedly of Morgan Le Fay, he is best known in Chrétien de Troyes's stories. He had heard of a magical spring in the forest of Broceliande where it was defended by Esclados. Owain later married Esclados's wife, Laudine. When he traveled with King Arthur, he promised his wife that he would return, although he didn't. When he finally did, she rejected him and he became very upset and went off into the forest. There, he then saw a lion fighting a serpent and helped the lion out. From then on, the lion became his companion.
