The Valkyries were once Odin’s greatest warriors who ferried the dead to the eternal resting place of Valhalla. Odin tells it that their duties asked too much of them and their minds were corrupted. In fits of uncontrollable rage and anguish, they began to slaughter the warriors they once protected. Only four Valkyries survived the war; in their cowardice, they fled to Midgard and hid amongst the mortals. You have been tasked with finding the last Valkyrie and destroying her, once and for all ending the Madness of the Valkyries. But there may be more to learn in the once-great halls.
