Brynhild remains unconvinced, and plans Sigurd's death, and threatens Gunnar with the loss of dominion and life, if he will not kill Sigurd. After some hesitation, Gunnar consents, and, calling Hogni, informs him that he must kill Sigurd, in order to obtain the treasure of the Rhinegold. Hogni warns him against breaking his oath to Sigurd, when it occurs to Gunnar, that his brother Gutthorm had sworn no oath and might do the deed. Both now proceed to excite the latter's greed, and give him wolf's and snake meat to eat to make him savage. Twice Gutthorm makes the attempt, as Sigurd lies in bed, but is deterred by the latter's penetrating glance. The third time he finds Sigurd asleep, and pierces him with his sword. Sigurd, awakening at the pain, hurls his own sword after his murderer, fairly cutting him in two. He then dies, protesting his innocence and designating Brynhild as the instigator of his murder. Brynhild at first laughs aloud at Gudrun's frantic grief, but later her joy turns into sorrow, and she determines to share Sigurd's death. In vain they try to dissuade her; donning her gold corselet, she pierces herself with a sword and begs to be burned on Sigurd's funeral pyre. In dying she prophesies the future, telling of Gudrun's marriage to "Atli" and of the death of the many men which will be caused thereby. After Brynhild's death Gudrun in her sorrow flees to the court of King "Half" of Denmark, where she remains seven years. Finally Grimhild learns of the place of her daughter's concealment, and tries to bring about a reconciliation with Gunnar and Hogni. They offer her much treasure, if she will marry Atli. At first she refuses and thinks only of revenge, but finally she consents and the marriage is celebrated in Atli's land. After a time Atli, who is envious of Gunnar's riches, for the latter had taken possession of Sigurd's hoard, invites him to his court. A man named "Vingi", who was sent with the invitation, changes the runes of warning, which Gudrun had given him, so that they, too, read as an invitation. The brothers determine to accept the invitation, and, though warned by many dreams, they set out for Atli's court, which they reach in due time. Vingi now breaks forth into exultations, that he has lured them into a snare, and is slain by Hogni with a battle axe.
