Rise Of The Antichrist

A powerful, international cult centered in France is quickly gaining momentum across the world, sweeping up occultists, practitioners of witchcraft, alternate religious types and even militant atheists under its banner.  And what does this cult proclaim?  That a young boy who is supposed to be the spiritual head of the cult is in fact the living, flesh-and-blood son of Satan himself.  The Antichrist.
Christian theology aside, the characters must race across the world to hunt down the centers of power of the cult and dismantle them.  And once they work their way up to the top, what do they discover?  The kid is a fake!  But the real problem is that the cult isn't...  the worship of the followers has been powering a slumbering archduke of hell, a demon of great power, who is now awake and clawing his way up from the depths of hell!
What will the characters do?  Will they simply kill or arrest all cultists?  Will they try to evangelize and convince them the cult is a fraud? What about the kid? How will they stop the Greater Demon?
