Progia, a land ruled by the sword and guarded for a millennia by an ancient Order. Castle Serilis is the last fortress standing against the coming darkness. Protected by a mystic veil, the castle emanates a dark song that lures evil away from the kingdoms of men. The Warriors of Serilis are the last line of defense between a monstrous horde and a world that has forgotten them. They have withstood nightly assaults by the undead for nearly a thousand years. Until the night, one of their own betrays them. In an epic struggle for survival, the defenders of the realm stand against an army of undead led by the Legendary Vampire Lord. If the castle falls, he will unleash a long slumbering nightmare upon the world, the immortal wizard known as The Cama'thul.
