Valkyrie

In Norse mythology, a valkyrie (from Old Norse: valkyrja, lit. 'chooser of the slain') is one of a host of female figures who guide souls of the dead to the god Odin's hall Valhalla. There, the deceased warriors become einherjar (Old Norse "single (or once) fighters"). When the einherjar are not preparing for the events of Ragnarök, the valkyries bear them mead. Valkyries also appear as lovers of heroes and other mortals, where they are sometimes described as the daughters of royalty, sometimes accompanied by ravens and sometimes connected to swans or horses.

From poem Helgakviða Hundingsbana:

"Helmeted valkyries came down from the sky
—the noise of spears grew loud—they protected the prince;
then said Sigrun—the wound-giving valkyries flew,
the troll-woman's mount was feasting on the fodder of raven."

Towards the end of the poem, valkyries again descend from the sky, this time to protect Helgi amid the battle at Frekastein. After the battle, all the valkyries fly away but Sigrún and wolves (referred to as "the troll-woman's mount") consume corpses.
