Unfortunately for her a war destroyed her nation and brings extinction to the vampires, while herself being cursed and sealed in a forgotten dungeon, left to crumble through time. Her once enigmatic self has degraded in an ocean of regret, wishing an end to her isolating prison of eternal life. All of that changes when someone finally opens her seals and free her from the cursed chains that imprisoned her, giving her a new hope for another chance to life.
