The Valkyries of Norse mythology were women of vast prestige and power.
Known as beacons of strength, when seen by the male soldiers on the ground, both awe and terror would sweep the battlefield – their role was to determine the fate of fallen warriors.

Despite this overwhelming awe, it is the duty of the Valkyries not to participate in the wars of mortals or to have a role in the physical or mental acts of battle, but rather to choose from the fallen humans who was worthy enough to ascend to the halls of Odin, and who was benign enough to be sent to the fields of Freyja, Odin´s hall, Valhalla, holds the spirits of the warriors in constant training—their sole purpose in the afterlife is to prepare for the battle that will be the end of the world, Ragnarök, and to defend their universe as best they can from Loki and his army.
