Well it´s about time I post Chronius description and a brief history:
Chronius´ skin is of an unhealthy yellow, stretched on his skull, not unlike a dried corpse; the scarce hair is of a dirty white and hangs loosely. The lips are tensed in a perpetual smile, hideous as the warped magical aura around him. Children cry and animals hiss at his passing. When he´s out of the laboratory he normally wears a hood and simple brown, monk-like robes.
Chronius real name is Alfonso, but he has not used that name in many years. He was the son of a lowly servant, back in the court of an aragonese count. His ealy years were lonely and sad, rejected by others because the uneasy sensations others felt when he was around, until he was around 8 and a Jerbiton mage that visited the court regularly recognized him as a Gifted.
The wizard already had an apprentice, so Alfonso stayed were he was, but Desmados, a wizard from a mostly Flambeau and Tytalus covenant in the provenzal tribunal heard of him and decided to take an apprentice. He was sold without much thinking or regret, and two years later he started his magical studies, after quickly mastering his first studies and learning to write and read.
Life in the covenant soon became very competitive. Apprentices –who, by the covenant´s custom, started their training at roughly the same time- were tested together regularly, and benefits were given depending on how –relatively- well they fared on them. Thank to his keen intelect and his newly awakened aptitude for studying, Alfonso –renamed Chronius thanks to his uncanny undertanding of the effects of time on things- easily won most of them, and that meant the enmity of his peers. Isolation from them only made him to work harder on his studies, and made him develop a resentful and unfriendly personality.
The enmity between him and the other apprentices climaxed when they voilated Chronius´ paren´s laboratory and rigged an experiment Chronius was about to start, adding Vis stolen from the covenant´s reservoir. The vast amount of Perdo magic was too much for the unexperienced Chronius to control, and the magic coursed through his body, almost killing him. When he awoke, he wasn´t the same, and his face was turned into a hideous, corpse-like visage. *
Desmados demanded a severe punishment for the violation of his Sanctum, and normally the Hermetic law would have backed him. However, the twisted politics at the covenant complicated the matter. Other magi saw that as an opportunity to weaken Chronius´ parens, and defended their apprentices to the end. They suffered minor punishments, and Desmados´ position was badly weakened; in a few years time, Chronius finished his studies and passed his Gauntlet. Being now a member of a covenant filled with enemies**, he was forced to leave, and decided to put as much miles between him and them. Finally, he arrived at Gormenghast.
*The Twilight points flaw would have been more appropiate, but I felt better to do it build it the way I did.
** I considered taking the enemies feat, but they are not so powerful, and too far away to be a real flaw.
