About
Duke Duralumin is next in line to the throne after Sapphire. He is constantly trying to discredit Sapphire in order to inherit the throne. He is a fairly hands-off villain; he makes speeches to try to turn the people against Sapphire, but leaves the actual physical work of kidnapping and thuggery to his blackguard enforcer.
