A ravening horde of barbarians from the East, the Mosul Empire, in unholy alliance with the Teutons and the Mameluke warlords and led by the brutal theocracy of the Zhaithan, has subjugated the Land of the Franks and the Hispanic Peninsula. Setting their sights on the New World, they have already conquered the Republic of Greater Carolina and the Virginia Freestate. Only the Kingdom of Albany still stands, aided by the Norse Alliance of Britain and Scandinavia. Four youngsters from very different backgrounds are brought together to form The Four -- a supernatural entity that becomes the last-ditch hope of the Free World.
