After a laboratory incident, an odd mix of chemicals was let into the air. The upside was that they only affected one quarter of the population, and gave them supernatural abilities. At first, people tried to accept these changes and move on, but bad apples in the bunch poisoned normal people's ideas of the Supers. There was a movement to lock the Supers up, but people took it too far, going on to torture and torment those caught.
Mark, a powerful Super, didn't stand for this. He rose up and rebelled, wiping out many Regulars (those without powers) in the process. This allowed Supers to rise up with him and rule. Despite the weak resistance he may face, Mark sits atop the world, prepared for anything.
Jack is a Regular who was 'lucky' enough to survive the Cleansing. He's enslaved to the Supers and lives terribly nowadays, barely making it on a day to day basis. The worst mistake of his life was the day he bumped into the worst Super of them all, Mark.
But was it truly the worst mistake, or will it be the best coincidence?
