The Valkyrie ("chosers of the slain") are beautiful young women, mounted upon winged horses and armed with helmets and spears. Odin needs many brave warriors for the oncoming battle of Ragnarok, and the Valkyries fly to each battle that is waged in Midgard and choose the bravest of those who have been slain. They then escort these heroes, called the Einheriar, back to Valhalla.

The queen of the Valkyrie is Freya. The Valkyrie are also Odin's messengers and when they ride forth on their errands, their armor causes the strange flickering light that is called "Aurora Borealis" (Northern Lights). The Valkyrie are also known as the virgin demi-goddesses, the warrior maidens of Odin.

Some of the Valyries are Brynhildr, Göll, Göndul, Gudr, Gunn, Herfjoturr, Hildr, Hladgunnr, Hlokk, Hrist, Kara, Sigurdrifta, Sigrún, and Svafa.
