In Norse mythology, a valkyrie 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. When the einherjar are not preparing for the cataclysmic 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, boars or wolves.
