Maine "Hell on Earth"

In the late Spring of 1989, Satan claimed most of the state of Maine as "proof that Hell is real and God won't do anything to stop me." 75% of the state is now riddled with Hellmouths and demonic looking castles and other satanic architecture. On the other hand, most of the wilderness is left untouched and animals just avoid the hellish places. Human habitations are falling apart and being reclaimed by nature. Demons and monsters roam the land, looking for humans to seduce, kill, corrupt or just eat.

At first, there was mass panic and everybody blamed Stephen King. Eventually, most folks decided it wasn't his fault, but he still moved his family to California, just to be safe.

The United States tried to do air and artillery strikes on the forces of Hell, but they failed miserably. Planes blew up, missiles and artillery shells turned into everything from excrement to swarms of locusts and turned back on US forces and any attack by ground forces was almost instantly destroyed by demons.

Eventually, the government (in many places aided by the Canadian government) built a 100 yard wide paved border around most of the state. Satan approved of this and even placed a two foot high brick wall along the inner edge of the border. He swore that he and his minions would only attack those people who crossed the wall. Not being the most trusting of folks, the government also forbade any human habitation closer than 3 miles to the border and then they patrolled the border 24/7 using robotic tanks and mobile gun platforms controlled by humans several miles away.

So far, as of 2014, Satan has kept his word and no hell spawn have crossed the border. Sadly, a couple of hundred crazy people, stupid/drunk teenagers and religiously deluded men of the cloth sneak over the border each year. This shows incredible determination, since there are now an electrified fence, razor wire and about 125,000 video cameras on the border. On the plus side, most of Maine is now well on the way to a fully regenerated post-human ecosystem.

It should be noted that so far, God has not done anything about the overall situation, despite frequent and heartfelt requests.
