Overview
Three thousand years ago, a clan of vampires fought as vassals for the Demon Clan in the Great Holy War. Sometime during the war the Vampire King Izraf had plotted a secret rebellion but failed, and as such the vampires were to be made an example of what happens to traitors. Zeldris of the Ten Commandments was tasked to execute them but instead chose to seal them away in an ancient sarcophagus, which he did to save Gelda from death. Twelve years ago through some unknown means the seal was broken and the Vampires escaped. To reestablish themselves they chose to conquer the Kingdom of Edinburgh, doing so in one night by massacring the population and turning them into vampires along with its Holy Knights.
