Valkyrie, the fearsome Asgardian warrior entrusted with conveying worthy souls to the heroes’ afterlife, stalks a battlefield finding only empty husks. Yet the souls are not already in Valhalla, or the lesser afterworlds – they have vanished. She enlists the aid of the valiant Lady Sif, and together they scour Asgard for answers. Rumors abound of towns being attacked by a horde of soldiers who cannot be killed. Someone is building an immortal army and stealing Asgardian souls… A worthy challenge for two of Asgard’s mightiest champions!
