In the world full of undead and monsters. The Lone Grey Wolf, known as just a soldiers story for those who returned from their expeditions, has made her way to one of the Sanctuary’s. No memory, just an instinct to do what has to be done. Many fear her, until one night as she snuck in Noah’s home. Not knowing what she got herself into. Times running out for Gray. She must hurry and remember her past before it’s too late for her and humanity.
