Karyth is a brilliant but unremarkable mana-tech researcher on Eidolon Station, a sprawling metropolis where magic and technology coexist in a fragile truce. Driven by dreams of creating affordable, sustainable mana batteries, he’s spent years chasing breakthroughs—and just as often, weathering failures. His companion, Eirys, a witty and perceptive AI, is both his greatest support and most relentless critic, keeping him grounded when ambition clouds his judgment. But everything changes when an experimental stabilizer crystal—a fragment of what he later discovers to be the crystallized blood of an Old God—explodes during a routine test. The blast nearly kills him, leaving his body broken, burned, and marked by strange glowing scars. Worse, the accident rewrites his DNA, imbuing him with eldritch power he barely understands and can’t control. As Karyth struggles to recover, he faces not only the physical pain of his injuries but the psychological toll of his transformation. Eirys, always by his side, urges him to confront his fears and seek help. Therapy offers a glimmer of hope, but the changes within him deepen, pulling him toward a destiny he never asked for. When Karyth learns of a growing threat tied to the ancient power now flowing through his veins, he is thrust into a dangerous quest that will take him far beyond the familiar confines of Eidolon Station. Joined by Eirys—who grows increasingly sentient and deeply attached to him—and a team of unlikely allies, Karyth must unravel the mysteries of the Old Gods and their connection to his transformation. Caught between humanity and the eldritch forces reshaping him, Karyth must decide whether to embrace the power threatening to consume him—or fight to retain the fragments of his humanity. His journey will challenge his beliefs, redefine his relationships, and force him to confront the question at the heart of it all: What makes someone human in a world where magic and technology can rewrite reality?
