Psychic!
Because of his abilities Cristopher was hated by many people, including his parents. At the age of 10 he left home and began living on his own, going through the proper channels to become an emancipated minor. While living on his own he became involved in the criminal underworld and quickly made a mark as a gambler and later as an enforcer. When one man thought he was cheating they attempted to beat him down, that's when Cristopher discovered that his skill could do more than just tell him what the outcome of a dice roll would be. He could predict where they would throw the punch making it so that he wasn't there. After this Cristopher became a small time enforcer. Cristopher never attended real school but rather educated himself, reading everything he could in the hopes of understanding what it was that he could do. His knowledge is missing huge gaps in some places because of this but in other areas he has more knowledge than most. Swearing to leave crime behind for a good he became an upstanding citizen, all for a girl. It would be a few days later that this same girl would go missing, Cristopher became obsessed with trying to find her. He joined Psy Prep in the hopes of tracking her down someday.
