Lure of Destiny
North America has been invaded by raiders from another reality. They have come to steal Earth’s possibilities. These Possibility Raiders have brought with them their own reality, and now portions of North America have become someplace else.
Now parts of both coasts and the far north have fallen to the invaders. Technology refuses to work. Men and women are succumbing to primeval urges and joining the invaders’ camps.
Now dinosaurs control New York, a vast jungle encompasses Sacramento, and a Deep Mist pervades significant chunks of the United Sates and Canada.
