In a world where magic is bonded to celestial creatures known as Astral Familiars, an ordinary teenager is suddenly chosen by a fallen star, awakening powers they never knew they had. Taken to Starborn Academy, a hidden school that trains Celestials—magical warriors who protect the balance of light and dark—the protagonist soon discovers a cosmic war brewing in secret. But something is wrong. The Celestial Order, the council that governs magic, has been hiding a dark truth: the world is running out of stars, and once the last one fades, magic itself will die. With their newly awakened powers and an unruly Astral Familiar (a unique, never-seen-before creature), the protagonist must uncover the lost history of the Celestials, forge deep bonds with their team, and prepare to battle an enemy that has been waiting in the shadows for centuries.
