In five years before Reign of the Seven Spellblades, there was a young man named Alvin Godfrey who enrolled at Kimberly Magic Academy with low self-esteem. Initially unable to cast any spells, he faced ridicule from his peers. Despite this, he persevered and eventually became friends with others at the academy. Eventually, he rose through the ranks to become the student body president, earning himself the nickname Purgatory.
