Materialization
"Ever heard of this? The course of the world is about to change."
Ages have gone by; the world is rotting to shambles. The skies are damaged; the air is poisonous and the suns radiation filters through the atmosphere as fiercely as ever. Lands are barren, nature is a rare sight nowadays and lakes are tainted. Earth has been infected to the very core.
The source of such disgrace lies on the shoulders of humans, a burden they seem to ignore and turn fault to everyone but themselves. They are too greedy, technology and several years of war brought destruction over their own kind.
In this futuristic world, the only thing that keeps them from extinction is their own executioner. Thanks to technology, they developed capsule cities to conceal themselves from the outside world, allowing them to endure the hard times. These cities are ruled by the church. Religion took over as the new government, keeping the population ignorant about their current situation while recruiting in secret those outstanding people for a several number of different tasks.
Those who didn't agree with this government live outside in the wild, in small towns scattered all over the world. These are the people who risk contracting several lethal illnesses due to exposure to radiation and air contamination, not to mention the scarce food sources; nonetheless, these people are more aware of their condition: Vampires are attacking humans again and their numbers are growing.
Yes, vampires; those undead creatures started abducting people and now were starting to annihilate entire towns for unknown purposes, to humans at least. Actually, ages ago, vampires were almost exterminated due to a bio-weapon massive war (alongside the Earth's toxic condition) and their distinguished long life-spam shortened. They no longer live forever, instead, they started deteriorating at a faster rate; they also lost or got weakened some of their trademark powers. Now, vampires can be affected by common bullets and no longer possess an inhuman speed or power, at least not all of them. Most vampires, who were turned against their will, were more than glad to disintegrate and disappear; while a few others truly evil remained, and those were who caused trouble nowadays. Those vampires are seeking revenge and searching for a cure, a way to restore their former glory, vampires thirsty for blood of the people who damaged their reputation.
The church, of course, acknowledged this. Although the try to maintain this out of public, they send small squads of capable humans on missions to raid strategic points out of vampires to weaken their forces and prevent a bigger conflict; though, they are just delaying the imminent war that is about to break loose. Vampires taking over the world and humans ignorant of the predator stalking from the shadows...
