Leo was typical, overlooked and completely unprepared when a forbidden tome chose him and gave him the mark of a Warden and placed him under the Mage Academy. This school is an intermediary between worlds, a training ground where recipients of a gift of a System Interface, called a Codex, are trained. However, the file of Leo himself is empty, his Codex whispers that they are “unfinished,” and the elite at the Academy are watching him with suspicion and fear. Dropped into a realm of magical rank and fatal challenges, Leo is an exception. His magic is not dead, but a forbidden energy, which develops by consuming the magic and memories of others. In a maimed mentor who has an overabundance of knowledge, a genius competitor with a cursed lineage, and an ally with a talent to outwit the street, Leo discovers a rot inside the Academy. It is not merely teaching magic, it is harvesting it, it is tapping its students with the souls of its former students to feed its immortality, all managed by an enigmatic, manipulative Headmaster. As the boundary between the magical and the mortal realms collapses, Leo gets to know the horrifying reality of his destiny. He is a “Fractured Soul,” a descendant in an intergenerational cycle, who will either redeem the world or ruin it. In order to escape the cycle, he should learn how to overcome the same force that is eliminating his human nature and face the most outrageous truth of all: the man who has tortured him is his own father. The world has become the teacher, but Leo now has to rewrite the final lesson. Tags: Progression Fantasy, Academy Fantasy, Gaslamp Fantasy.
