@SuperPikameeFriend @970ab77f @ЯAUL👹lum lover🍚🔥 there's a short book by Edgar Rice Burroughs, The Lost Coninent, where the entirety of civilized Europe has fallen and reverted to a stone aged people after WWI, and the more civilized and organized muslim negros are conquering all the way into Northern Europe. 
(good book, btw)
