The two largest superpowers collide in a deadly conflict, dragging both allies, and the entire world in with them. Just a small portion of people survive, about 15-20%. Among them is a young man, who works as a courier for the CF, or the Cole Federation. A small nation that developed in North America about a year after the "apocalypse". He is forced to navigate both the perils of his new world, and that of Equestria.
