At the elite Aetheris Academy, every student bonds with a powerful Astral Beast—except Caelum Viremont. For three years, he has carried a dead obsidian egg that refuses to hatch, making him the academy’s greatest failure.
But when the fractured moon above their world begins to collapse, the silent egg finally awakens. What sleeps inside is not a beast, but an ancient cosmic entity tied to the destruction of the stars themselves. As terrifying powers emerge and the academy’s hidden secrets unravel, Caelum realizes he was never meant to become a hero. He was chosen to become something far more dangerous.
