Ren Kronos is an 18-year-old boy whose parents died when he was twelve. They were eaten by a dragon on a trading route in Ayanna. After three days of solitude and having eaten everything in the house, Ren roamed the vast Ayannan landscape. Eventually, he ran into two men. One of whom was small and frail, the other tall and built. The frail man's name was Jiri Alois. This man taught Ren the anatomy of the monsters in Ayanna, so that he may traverse the land unhindered. Jiri also taught Ren a small amount of sealing magic, magic powerful enough to kill a dragon. The magic traps its target and obliterates it. It is such a powerful spell, it exhausted Ren after each use and he would not be able to use it again for another four days. The other man, Plouton Hercules, knew much about the martial art, Muay Thai. Plouton taught Ren all he knew before leaving the boy with Jiri. Ren studied everything he could about dragons and civilization hoping one day his life would return to normal. Jiri continued to help the boy with dragon anatomy and conceived many different types of training tools for Ren. Ren, after five years, was capable of taking on the dragon who killed his parents. After a sad goodbye to the camp and a dangerous trek, he had found the dragon. He quickly scaled the mountain with ease. The battle had begun. After fire was spewed all over the den, and deadly blows delivered to the demon's belly, Ren had won. He had also lost. His left hand was completely gone. He returned with haste to Jiri. Jiri spotted Ren's hand and began working immediately. Jiri created a mechanical hand that would allow Ren to summon his Sealing magic quicker and reduced the cool-down effect of the spell. Ren could now summon the spell again within two days. Jiri kept the blood from his arm in a mechanized cooling device [freezer basically].
Ren was now 17 and on his eighteenth birthday Jiri gave Ren all his Bishan[10,000 worth] and a stone of hardened blood before saying goodbye. Ren, now old enough, to traverse the land began his journey to protect the horrid world from itself and the demon's that infest it.
Ren was a kind boy, playful, yet strong. He was very fond of children and was able to do manual labor if needed. He never stayed in one place for more than a week. This made him a mysterious character to children and quite annoying to his employers. But, many could not understand why everyone liked this stranger. He had a hand made of metal, sharp, deadly and cold. Yet the children played with it like a toy. He spent his spare time lounging or training. Love was an issue for him, he never found one that could suit him. He scarcely got into fights to avoid negative attention. The only thing he did not mind fighting was a monster or demon.
