Who are the Valkyries?

Odin permits a number of the Valkyries to select the kind of lovely white swans, however when a Valkyrie is observed by a person with no swanlike disguise, she’ll develop into a normal mortal and can not return to Valhalla.

The Valkyries are feminine warlike virgins, who mounts upon arms and horses with helmets and spears. The Valkyries decides who’ll die in a conflict, they’ll hover over the battle, like birds above their prey. There will be six, nine, or even thirteen Valkyries at one time.

Half of those warriors the Valkyries select will visit Valhalla in Asgard. Freya consistently has the first choice, of those fallen Vikings.
