Song of Blood and Wine

In this world of demons and monsters, truth and lies were intertwined. If one were to carelessly open the abyss of the dark side of the world, one would find that disaster had already befallen the world. This was a world controlled by the Blood Clan. Each of the Seven Great Families controlled one side of the world and controlled the world from the shadows. However, no one knew where these vampires came from or what their world was like. That was until a silver-haired young man appeared and used his Fate Thread to bind the two parallel planes together! Was it a disaster or a rebirth? Was it a disaster, or was it luck?
