In 2012, a strain of a biological weapon escaped from a top secret laboratory. This weapon, loosely called the Perago Strain was highly contagious and yielded interesting and random results in it's victims. Within two weeks of it's escaping the lab in Danford, three-quarters of the world was infected by it. The results were random, and they were disturbing. Most died from it as it destroyed their immune system. Some proved immune to its affects and continued on as if nothing had happened. Those that contracted it and survived it, however, had some interesting changes. Some were affected physically, growing extra limbs, or shifting into animals. Others developed strange powers from the virus, becoming invisible or lifting cars by the dozen.
