Locke and Eric storm into the basement of Marquis Mastafon's mansion. While Eric rescues the Marquis and Marquis after a fierce battle with the Vampire Lord, Locke leaps alone into another dimension beyond the mirror to save the Marquis's daughter, Philly! Locke defeats countless vampires and unleashes all his power against the High Lord, who is plotting to summon the "Dark Gods" by sacrificing Philly. However, the High Lord finally opens the door to another world, summoning the demons!
