Underworld Unfinished Business 4: Taking Care of Business

Following the demise of The Lizard King, the three remaining Dark Souls, Belial, Madam Orr and Legion, are holed up in their stronghold at the base of Hell. Only Lucifer himself lies below them. It is believed this unholy trinity plan to join forces and storm Lucifer's realm, topple Lucifer and place Madam Orr on his throne. Of course, all of this is conjecture. No one actually knows what's down in Lucifer's realm, or even if Lucifer exists anymore. However, Team Anubis firmly believes it is better to keep the Devil you know and so these Dark Souls must be stopped.
