GURPS Mage: The Ascension

From the back of the book: Truth until paradox Humanity lies ignorant, wandering through their empty lives like sheep. The true power in the world comes not from wealth or armies or science. There is only one true power. The arcane arts. The power of the soul. Reality Programming. Magick. Enter the World of Darkness, where mages of the awakened Traditions battle the cold Technocracy in an ancient war to decide the fate of humanity's fragile souls. Wield incredible, earth-shaking power, but do not be too arrogant, for all power has its price. The forces of Paradox wait to destroy those who bend reality too much. Enter a world without limits. Enter a world where everything is possible.
