 At the beginning of the poem Helgakviða Hundingsbana II , a prose narrative says that King Sigmund ( son of Völsung ) and his wife Borghild ( of Brálund ) have a son named Helgi , who they named for Helgi Hjörvarðsson ( the antagonist of the earlier Helgakviða Hjörvarðssonar ) . After Helgi has killed King Hunding in stanza 4 , a prose narrative says that Helgi escapes , consumes the raw meat of cattle he has slaughtered on a beach , and encounters Sigrún . Sigrún , daughter of King Högni , is " a valkyrie and rode through air and sea " , and she is the valkyrie Sváva reincarnated . In stanza 7 , Sigrún uses the phrase " fed the gosling of Gunn 's sisters " . Gunnr and her sisters are valkyries , and these goslings are ravens , who feed on the corpses left on the battlefield by warriors .
