Before creation as we know it, two primordial beings existed: one representing light and life, the other darkness and decay. Together, they shaped the world—one bringing forth water, grass, and life, while the other countered with rot, corruption, and death. Their creations clashed, but humanity flourished under the light-bringer’s guidance. In retaliation, the being of darkness corrupted a human, turning it into an unrelenting monster—what would come to be called a demon. When humanity could not stand against this new terror, the light-bringer intervened, granting two humans the ability to synchronize their spirits. One would become a weapon, wielded by the other. Together, they vanquished the demon, earning the title "Children of God." These two gave rise to descendants who carried their divine gifts, battling the growing plague of curses. From their bloodline, an exorcist society was born. As it evolved, new abilities emerged: elemental powers, enhanced physical strength, and unparalleled mental acuity. Over time, society splintered into a hierarchy: royal families, direct descendants of the Children of God; the mid-class, those with moderate spiritual energy; and the criminal syndicate, where those with little to no spiritual energy were cast aside. Despite this division, some, like Ryan Sheil and his father Richard Michael Sheil, rose from the syndicate to power. With unmatched spiritual pressure, they shattered expectations, with Ryan becoming a bishop and Richard ascending to lead the exorcist society itself. But this story does not belong to them. It belongs to Ryan's children—Sully, Coby, and Robert. Together, they will form the strongest exorcist team in history, carrying the legacy of the Children of God into a new era of light and darkness.
