Prologue.
The day the world ended began like any other.
At 2:00 pm, hour of the Central Krizanian Empire, on Monday, June 15, 2045; the world faced a dire threat, one that could end life in a global scale; only, that in this case,
it wasn't a meteor or a massive superstorm.
It was a creature. It landed violently, crashing down like a meteor in the world of the Krizanian Empire's capitol. In seconds, whatever was that thing, it unleashed a massive infection like nothing that the world ever saw before. First, there were a few. Then, dozens...hundreds...thousands...millions.
The casualties started to grow like a cancer, rotting the hear of the One World; the capitol of the Empire, a city that stood in a magnificent way since the days of the Aztec Empire. It survived Spanish invasions, civil wars, volcanic eruptions and in the last fifty years, the rise of an age of heroes and champions. A world of Marvels.
Unfortunately, those marvels, those champions and demigods were destinated to fail.
Even after they fought with creatures, villains and demons that had the power to wipe out entire armies; even after saving the world from countless crisis and always rising victorious, this time, all those heroes and champions were the end bringers. The disease, as some media called it, focused on the strongest targets. Those with powers beyond the reach of any normal person. The disease was reckless and quick; regardless of species or gender, it infected anything and anyone beyond the range of 'normal' living things.
Heroes fought hard, valiantly against the 'patient zero', but the only thing they managed to accomplish was to get infected themselves.
The first ones to fall were the Predators, the average street-level team. All of them were the first line of defense against the 'patient zero.' Then, it only got worse. The Shadowmen, half of the City Knights and many others fell in combat or got infected. Heavy powerhouses, speedsters, mercenaries, psionics...no one was safe. The once proud champions and heroes turned into the demiurge of the denizens of the cities they protected a few minutes before.
The ferocity, the speed and the many powers and abilities of the infected helped them to wipe out any lifeform in the boundaries of Dragon City, Lancaster and Troodoken. Without the guidance of the Triple Alliance, the Krizanian Empire began to crumble like the ancient nations that they conquered hundreds of years ago.
After Dragon City was left lifeless, the infected started to roam through the One World Valley, and the world was never the same.
The White Dragons, the Night Walkers, the City Knights and many other superhero teams were infected. Those who were champions, those who were saviors, those who were hope and inspiration for all the people, were turned into doom bringers. Eating. Killing. Destroying. Soon, cities like Shinedo, Eikana, Aztlan and many others fell.
Now, only the southeastern and far northern regions remain. In the southeast, the city of Itzá, once capitol of the now long-gone mayan empire, was being protected heavily by the remaining forces of the Empire Army. In the north, the always frozen wastelands of Footracer were a pretty sure hideout for survivors.
But it was only matter of time before the superpowered zombies expanded their brutal disease into those areas.
