As hero of the story, the Arthurian knight Yvain embodies the courage, gallantry, and romantic devotion of the medieval code of chivalry. His decision to avenge his cousin Calogrenant’s defeat in battle sets him on a course that will challenge his soul and alter his character. Young, strong, ambitious, and ardent, Yvain is torn between his love for Laudine and his desire to travel on a quest for combat victories and knightly glory.

Led astray by his desires to travel and joust, Yvain spends the rest of the story trying to win back Laudine’s love. Ironically, it is the heroic deeds Yvain performs in an attempt to win her back that prove him worthy, as Yvain demonstrates his good-heartedness and shows he has outgrown his irresponsibility. In that respect, he reconciles both sides of his character, winning both knightly glory and his love interest. 

Heir to Duke Laudunet and recently widowed, Laudine presides over Landuc Castle without a champion to protect its vital resources, especially the magical fountain of the Brocéliande Forest. While mourning the death of her beloved husband Esclados, Laudine finds that her best hope is the very man who killed him, Yvain. Tortured by conflicting emotions, Laudine resolves them by falling deeply in love with Yvain.
