A man named Theon, at age 30, passed away suddenly and found himself reborn in another world. Despite his initial optimism that there would be magic here, he discovered that this new realm lacked any magical abilities. Feeling disheartened and sluggish, an event occurred which led him to realize the existence of magic. With determination, Theon began studying magic from then onwards. Eventually, a disease spread throughout the land that could only be cured through the use of magic, and he encountered an adversary who could only be defeated by means of magical powers. Through his perseverance and indomitable spirit, Theon emerged as a hero who saved the world, ultimately spreading magic to its people. This is the tale of a humble magician who, despite being buffeted by fate, overcame it through the power of magic and an unwavering resolve, eventually bringing magic to the masses.
