Valkyrie

Specifically Valkyries are spirits of battle created by Vayne who reside in the Hall of the Guardians, a demiplane where those warriors await the final battle. Among scholars the term valkyrie has been wrongly expanded to encompass many divine spirits of battle.

They true Valkyries are the “Choosers of the Slain” - those that measure the worth of a warrior and guide them in their afterlife. Those that are judged worthy are brought to the Hall of the Guardians where they live until the final battle when Vayne will call upon their strength to defend the Titan Gate from The Void.

Like other avatars a Valkyrie can change its shape to suit its need, but most of the time its shape is that of its nature. A Valkyrie will appear in the form of the species whose spirit it is aiding or guiding. It will always be outfitted for war, often with weapons and armor that resonate with divine power and purpose.

The valkyries are natives of the demiplanes that exist between the Divine Realms and the Mortal Plane. As beings that do no possess primal power they are free to come and go as suits their purpose. As spirits they are guided not by the free will of a mortal, but the divine purpose that created them. Their purpose is to guide great mortal warriors and serve them in the afterlife.
