Legend holds that thousands of years ago, the vampire queen nearly destroyed the world after unleashing her latent powers. Humans failed to defeat her despite their efforts, so they sealed her away, waiting for the day they would be strong enough to break the seal and kill her. However, humans are not the only ones seeking the seal. The vampire king, having abandoned his kingdom and betrayed both his own race and the dhampirs (half-vampires), continues to search relentlessly for the location of his queen's imprisonment. He aims to break the seal and free her before the humans can. Fearing that the reunited king and queen will continue to destroy the world together, humans and dhampirs hunt the king by any means necessary.
