I Made Up Forbidden Spells, and They Actually Worked?

After stepping into a realm of enchantment, Dean Bruce found himself mistakenly hailed as an esteemed wizard. Initially, he planned to firmly decline the captivating woman's request to be her mentor. However, the enticing offer proved too hard to resist. With no knowledge of magic to his name, Dean was left improvising spells on the fly. To his surprise, as the stunning woman executed his haphazard incantations, they unleashed incredible power. His hastily crafted enchantments – could they truly grasp the essence of magic, even the forbidden arts? As Dean rose to the pinnacle of magical mastery, becoming the High Mage, he candidly addressed a reporter from the Alliance during an interview: "I've never truly understood magic, you see. I simply created a few incantations," he confessed. His admission left people awestruck, viewing it as the genuine humility of a Grand High Mage.
