Magic Exchanger

Gothe is a magic exchanger. Whatever you want, you can exchange it with him. Want a son? No problem, trade it for a mountain. Want to be a village chief? It's cheaper for you, and you can exchange it for thirty years of life. There is no problem in being resurrected from the dead or living a long life. He can help you realize all your wishes, provided you are willing to pay the price. Gothe practiced white magic since he was a child and soon became a leader among mage apprentices. However, his fellow disciples used magic to harm him out of jealousy, and also harmed innocent people nearby. In order to save those innocent people, Gothe was forced to accept the devil's contract, losing his figure, appearance and emotions and turning into a short pig-headed man. And thus became a black magician. He uses black magic to help others, but the white magicians still regard him as their enemy and want to get rid of him. Black magic can save people, and white magic can also harm people. Magic itself is not good or bad. He lost everything, but he never lost his heart for good.
