Prismatic Melfelfon

Lore
legend tells of those who, upon their passing, were selected to become new guardians of the Heavens. The prismatic angel Melfelfon selected only the most courageous and noble for such a calling. The worthy were given mail made from an impenetrable, divine golden alloy, which also boosted the wearer's abilities astoundingly. The armor was not to be granted merely to those strong of body, but those who were strong also in spirit.

Name origin
In Norse mythology, a valkyrie (from Old Norse valkyrja "chooser of the slain") is one of a host of female figures who choose those who may die in battle and those who may live. Selecting among half of those who die in battle (the other half go to the goddess Freyja's afterlife field Fólkvangr), the valkyries bring their chosen to the afterlife hall of the slain, Valhalla, ruled over by the god Odin. There, the deceased warriors become einherjar. When the einherjar are not preparing for the events of Ragnarök, the valkyries bear them mead. Valkyries also appear as lovers of heroes and other mortals, where they are sometimes described as the daughters of royalty, sometimes accompanied by ravens, and sometimes connected to swans or horses.
