Sometime in Earth's future, after an age of peace and technological advancement, global war plunged the world into fire and madness.

Billions of people died, sending immeasurable amounts of psychic energy into the world's mystic ley lines — lines of invisible supernatural energy that crisscross the planet. The ley lines flared to life with unstoppable waves of energy creating storms, earthquakes, and dimensional anomalies. Where two ley lines crossed, the very fabric of space and time were torn asunder creating dimensional Rifts to other worlds. All manner of creatures and magic spilled forth from the Rifts onto the dying Earth, inadvertently transforming it into an alien landscape!
