Valkyries

The Valkyries are femail warlike virgins. They determine who will die in battle in groups of six, nine or thirteen at a time. They will select from half of the fallen warriors and bring them to Valhalla. The other half of the fallen will go to the goddess Freya's field, known as Folkvangr. Freya always has first pick from the fallen. Any Valkyrie seen by a human without her swanlike disguise will become mortal and can never again return to Valhalla.
