In a world where power comes from the stars and ambition is fueled by fame, Jin-Seong is a lone warrior navigating the dangerous balance between Celestial Essence and Heroic Qi. As a member of the Azure Peak Sect, he is burdened by his past and driven by the desire to protect those he cares about. Alongside his fiercely loyal disciple Yeon-Hwa, a young prodigy with the potential to become a Celestial Master, and So-Ra, a rogue warrior with a stormy heart, Jin-Seong must unravel the mysteries of the constellations that have chosen them.

Each warrior is bound to a celestial constellation, a cosmic force that grants unimaginable power—but also exacts a heavy toll. As Jin-Seong grapples with his connection to Ara, the altar of sacrifice, and Perseus, the hero, he is faced with difficult choices that test his resolve. The rise of the corrupt Hero Council threatens their world, forcing the group to confront their limits, their desires, and the true cost of power.
