It is mentioned that Brunhild and Gunther have a son, whom they name Siegfried. Some years later, Brunhild, still disturbed by Siegfried's failure to behave as a vassal, convinces Gunther to invite Siegfried and Kriemhild to Worms. Once the guests arrive, Brunhild becomes increasingly insistent that her husband is superior to Kriemhild's. This culminates when the two queens encounter each other in front of the cathedral at Worms, and fight over who has the right to enter first. Brunhild declares that Kriemhild is the wife of a vassal, to which Kriemhild replies that Siegfried has taken Brunhild's virginity, showing her the belt and ring as proof. Brunhild bursts into tears and Kriemhild enters the church before her. Brunhild then goes to Gunther and Gunther forces Siegfried to confirm that this is not the case. However, Brunhild convinces Gunther to murder Siegfried nonetheless. The deed itself is carried out by the Burgundian vassal Hagen, who justifies his action with the sorrow that Siegfried has caused Brunhild.
