Marvel's master of cosmic magic

Rowan Mercer was never meant to exist. Born in a covert mutant lab as Subject 757, he was engineered from the genes of Professor X and Magneto, then dismissed as a failure before he ever learned what he was capable of. His telepathy is faint, his magnetism weak, and the scientists who built him see him as little more than a disposable prototype.But Rowan is not alone in his own skin.The night he tries to sleep off another brutal training session, something in him fractures. His consciousness splits open, anchoring him to a second body in a different world entirelyan abused orphan in the shadows of Knockturn Alley, just days away from entering the wizarding world.Two bodies. Two lives. One mind.And then Rowan discovers the real impossibility:Every ability he trains in one world strengthens him in the other.Magic fuels mutation. Mutation fuels magic. And each new universe waiting beyond these two is another life ready to awaken.With X-23 preparing to lead a desperate escape, the wizarding world whispering of ancient power, and the multiverse itself unfolding like a map only he can read, Rowan begins to understand the truth:He isn't a failed experiment.He is the blueprint for something the multiverse has never seen.A survivor.A weapon.A convergence.And the worlds that created him have no idea what he's about to become.
