The American Midwest was drastically reshaped after the Great Imp War. Entire cities collapsed into the sea. The Great Lakes flooded to form one huge Great Lake. Northern Wisconsin was literally rounded off, and made the only decently habitable area in America.
The Impian Order's history goes back but four years.
It all began in a small town in Northern Wisconsin. Several imps were wandering about without their armor on, when a few kids came across them. The imps -despite their threatening appearance- appeared like rabbits to the kids, and they began to mess with the imps. These particular imps had very short tempers, and lashed out at the kids, killing all of them.
