The world has changed drastically since the fall of man. The ice caps have retreated and are now only existent at the very tip of the poles, destroying many coastal areas and flooding many ancient inland seas. Some mountain ranges have grown to epic heights, and some have shifted entirely due to the immense amount of magic that was released. Unlike Rifts Earth, where the ley lines flared to life, much of the available magic was diverted into bringing the Demon Princes realms in hell to Earth. Each piece of hell on Earth has created unique micro-climates, and has affected weather patterns and oceanic currents. Imagine walking through a dense tropical jungle, only to suddenly to find yourself in Arctic conditions, with an average temperature of -138º Fahrenheit, everything frozen in sight, and you in immedite danger. Similarly, there are now places on Earth where the seas and water instantly boil, and the land is completely barren, devoid of all earthly life.
