Humanity was conquered in the year 3966 A.D. by an alien federation known as the Reya empire. Because of this, there are tens of thousands of different alien species now inhibiting Earth. Humanity as it exists on the planet has changed heavily due to experiments, and because the present conditions are inhospitable for many humans. At present, society is divided into five main zones. Presently, you are in the forbidden zone. A place nearly uninhabitable due to chemical dumping, which created mutated anomalies. These zones are rated on a level of safety, and as such, the population of these zones is at varying levels of danger. The forbidden zone is the most dangerous, and few humans survive long. It is not a good place to be for anyone or anything. Predators are always lurking around the corner waiting for their next meal, and unlike most aliens seen in movies, these creatures are far more dangerous and intelligent than humans can imagine. The other zones are less dangerous, but still dangerous for different reasons. They contain the unknown, and anything could lurk in the shadows.
