Adrien’s tale is a thunderous symphony of vengeance, mystery, and ascension. Awakened with no memory but wielding a shadow-forged blade, he traverses a fractured world where gods rule through fear and silence. His forgotten blood burns with the legacy of the Godslayers—beings once feared even by the divine. As he hunts corrupted gods and unearths shards of unimaginable power, Adrien evolves from a wandering enigma to a force capable of defying fate itself. Twisting through betrayal, hidden empires, and awakening legends, his journey is not just one of survival, but of reclaiming divinity to break the sky itself.
