Before light found its name and before the first heartbeat of time, the Architects shaped infinity. They sculpted galaxies, molded dimensions, and breathed laws into the fabric of existence itself. Immortality, once their triumph, became their torment. The result was Eternavexus, a chaotic masterpiece where timelines, gods, and mortals coexist—and collide. But perfection cannot exist in chaos. From its golden veins, beings like Izayami Tsukihiro emerged—souls reborn through leyline echoes, destined to confront the sins of the Architects themselves. Now, the Architects seek to descend upon the world once more, but their divine essence cannot exist within fragile reality. Their arrival would shatter the balance that holds Eternavexus together. Amid this turmoil, it falls upon Izayami and his companions to stand against the Apostles, preventing them from completing their divine mission—and stopping the Architects from reclaiming the world they once abandoned.
