Historical Background of Rifts Earth

The year is 103 PA according to the Post-Apocalyptic calander used by the Coalition States. This translates to 2389 AD using the pre-rifts system. For three hundred years humanity has lived a pitiful existance, struggling to survive in a world overrun by horrors. Even now its existance is not assured, however it is only in the last fifty years that human nations have began to rebuild some form of civilization. With luck, humanity may yet unite long enough to reclaim the world.
The struggles of humanity go back to the mid 21st century. The nations of the world were in the middle of a golden age of science and learning. Great advances were made in many fields. Then, suddenly, the golden age ended. Countries became paranoid about the military applications of the new technologies. A new cold war began, a cold war that ended in nuclear fire.
On December 22, 2089 a volley of intercontinental nuclear missiles were launched. It is not known which country launched the first missiles, however all the nuclear powers quickly responded, and within an hour hundreds of millions of people died. However this was just the beginning. With every death a small amount of magic energy is released into the enviroment. When so many million people died the global level of magic skyrocketed. The ley-lines (natural channels of magic energy) surged, creating hurricanes, earthquakes, and tidal waves that killed millions more people, further increasing the level of magic. At the nexus points where ley-lines cross, great rifts in the fabric of spae-time were torn open, allowing extra-dimensional horrors to enter our world. The coninent of Atlantis lept from its watery grave and rose to the light of day for the first time in millenia. For every million or billion lives lost, the ley-lines surged and destroyed millions more. A nightmare of geometric principals.
Yet finally, the chaos ended. Mankind was decimated, with only a tiny few left alive, yet the survivors began to rebuild. However the Earth was permanently changed. Magic was now a known force, a power to be used for good or ill. Hundreds if different types of demons and aliens had entered the world, and more entered every day through fluctuating doorways of the rifts.
