Odin also directly intervenes during key points in the narrative. During a battle, Odin, again in the guise of an old, one-eyed man, breaks Sigmund's sword, turning the tide of the battle and ultimately leading to his death. He also stabs Brynhild with a sleeping thorn and curses her never to win another battle as an act of revenge for killing Hjalmgunnar, a rival king to whom Odin had promised victory.
