For countless aeons, the Devil Princes of the Nine Hells have been fighting over the infernal throne. The Devil Prince Astaroth, who was third in the rankings, suddenly found himself cast out onto the material plane, in a backwater realm where no devils yet lay claim. Is this game over, or could this be his opportunity to find an edge that will make him King of the Nine Hells?

Regardless, the material plane now has its work ahead of it, attempting to stand up against this great (lawful) evil.
