Later, Sigurd, who has gone to the court of the Burgundians (called Niflungs), advises Gunnar (Gunther) to marry Brunhild, and the two go to see her. She is angered that Sigurd has not kept his promise to marry only her—something which was not mentioned in their previous encounter—but Sigurd persuades her to marry Gunnar. She nevertheless refuses to consummate the marriage on the wedding night, and Sigurd must take Gunther's place (and shape) to take her virginity for Gunnar, which robs her of her strength.
