Warren Row was thought to be the weakest Mage, this is due to his Magic, which was that of one of the four weakest Affinities, Temperature Regulation. After barley being able to make it into a low tier Mage Academy, he trained day in and day out to ensure he could fulfill his duty as a Mage. But then the Great Calamity happened, a Grand Elder Beast by the Name of Dragono died, his soul unleashing a curse that killed any Mage above the Jade Rank, leaving only the weakest to push against the Monsters that roamed Iro and the evil intent of the Dark World. Twenty years later, Warren was able to both Destroy the Dark World and kill every Monster to extinction, forcing the world to be one of peace. A place where being a weak Mage was not an issue, but alas, after becoming so powerful and somehow managing to suppress his body to stay under Jade Rank, he could not hold back any longer. Making his body rot away as the curse was still invincible. Though, because his growth was so great, Warren immediately became a Golden God rank, meaning that he was granted one wish. That wish being to go and fix his regrets. Then, he is thrown Twenty five years into the past. A chance to stop the curse and save the world once again.
