Bestselling author Elias Vayne has spent years writing stories to escape the horrors of his past. As a child, he was the sole survivor of a massacre that wiped out his entire orphanage. He doesn’t remember how he survived—only that when the slaughter ended, he was the only one left standing.His latest work, The Arcane Academy Chronicles, takes place in Veylin Academy, a prestigious school of magic and combat. But one night, after finishing the final chapter, Elias wakes up inside his own book—not as the hero, not as the villain, but as an extra. Worse, he’s been reborn as Kael, the very same orphan who survived a similar massacre in the story.But something is wrong. The academy isn’t as he wrote it. Characters are acting off-script, unknown forces are rewriting events, and the mystery surrounding Kael’s survival mirrors the one in Elias’s real life. The more he tries to regain control of the narrative, the more he realizes this world may not be his creation at all.

In a world where strength determines one’s future, William, an orphan with no extraordinary talents, faces a grim destiny—until a brutal attack leaves him clinging to life. Instead of death, he awakens to a mysterious and powerful entity lurking within his mind: the Shadow System, a game-like interface that promises him unimaginable power. But this power comes with dark secrets, and refusing it would mean his death. Forced into a pact with a voice that can hear his every thought, William must navigate a dangerous new reality where shadow abilities and celestial power collide. As he enters the prestigious military academy, his newfound abilities draw both allies and enemies, all while a deadly conspiracy brews in the shadows. With the odds stacked against him, William must unravel the mystery of the Shadow System and decide whether to embrace the darkness within—or be consumed by it. His journey from a bullied outcast to a potential god will challenge not just his survival, but his very humanity. Power always comes at a cost—will William be able to pay the price? “What am I?” William asked the system. The system’s voice echoed in his head, cold and indifferent. “You are nothing.”
