In the dark corners of the world, a battle rages for the souls of the damned. They're known as The Fallen, souls afflicted with a curse that leaves them empty, violent, but immortal. The church calls them demons, vampires or the Nosferatu. For centuries a holy order known as The Righteous Fire has sought to destroy them, all the while hiding a secret that connects them, the church, to the beginning of the Nosferatu scourge.
Pollution, war and overpopulation have darkened the skies, photosynthesis is failing and most of the Earth's 20 billion souls face starvation and death. The only hope for survival lays with the fertile fields of Mars, where a 30-year terraforming effort is turning vast swaths of the red planet to green.
