Drap Niflunga (literally “The Killing of the Niflungs”) is not a poem but a brief prose note that summarizes the death of Gunnar and Hogni, an event that precedes the action of the next poems, and which is related in detail in the poem Atlakvitha.
Then Gunnar and Hogni took all the gold that had been Fafnir’s. They were not at peace with Attila, because he blamed them for his sister Brynhild’s death. But they made peace by giving Attila their sister Guthrun in marriage. They gave Guthrun a magical potion of forgetfulness before she consented to marry Attila. Attila’s sons with Guthrun were Erp and Eitil, and Guthrun had her daughter Svanhild by Sigurth.
King Attila later invited Gunnar and Hogni to visit him, and sent his messenger named Vingi or Knefroth. Guthrun suspected Attila meant to harm her brothers, so she sent a message in runes that said they should not come, and as a sign she sent Hogni the ring Andvaranaut with a wolf’s hair tied to it.
Gunnar had wooed Oddrun, Attila’s sister, but Attila had not given her to him in marriage. So Gunnar had married Glaumvor, and Hogni had married Kostbera, and their sons were Solar and Snaevar and Gjuki.
When Gunnar and Hogni came to Attila, Guthrun asked her sons to beg for her brothers’ lives, but they refused. Hogni’s heart was cut out, and Gunnar was placed in a pit of snakes. He played a harp and lulled the snakes to sleep, but one of them bit him down to the liver.
