Map and backstory of Aeisonia

Aeisonia is set in a alternate post-apocalyptic United States, in which the industrial revolution happened much earlier and the human race had no knowledge of what emissions were doing to the planet, leading to wide-scale governmental collapse and panic around 1930, at which point they realised that most low-lying an/or warm territory was doomed. The US and Canada both fell apart in about 1950 after the US attempted to invade Canada to get access to more temperate farming land to feed their dwindling population. With little access to fuel and food, the invasion failed, but succeeded in causing such widespread unrest that both countries both collapsed into squabbling mini-states. After about 110 years, a small nation based out of Delaware called the Commune of Aeisons swept across the former US and Canada, and quickly instituted order and a working economic system. The Aeison's goal was to create a version of the US that could be easily kept in check by the government. After the final battle of Vegas, the Aeisonian army declared victory in the United States and Canada, and renamed themselves the Federation of Aeisonia. Within a few years, society had flourished once more, and Aeisonia prospered. Scientific progress was now creeping along again, as were the economy. Birth rates were rising and great cities rose from the ground. The Aeisonian Federation gained new military and civilian tech faster than ever, and something that looked like the old world was starting to take shape.
