In verse 4674 a messenger of the Queen Fairy appears, and reveals to Lanzelet his origins and his name. Lanzelet learns that he is King Arthur's nephew, who he then decides to visit. Valerin tries to kidnap Queen Guinevere, however Lanzelet challenges him to a duel in which Valerin yields. Arthur's court celebrates his victory. Lanzelet then rushes to seek vengeance on the dwarf who whipped him in front of the Pluris fortress. He is made prisoner by the Queen of Pluris, who he ends up marrying. Meanwhile, one of the Queen Fairy's messengers makes the women of the court try on an enchanted coat in order to prove their fidelity toward their husbands. Lanzelet’s wife, Iblis, is the only person the coat fits perfectly. At the end of a tournament in which Lanzelet proves himself very cunning, Walwein, Karjet, Erec and Tristant manage to free him.
