In a world where every child awakens their **System Codex** at the age of ten, power defines one’s place in the world. Each Codex binds the soul to a class—Warrior, Mage, Summoner, or Healer—graded from Common to Divine. Advancement is everything.
But Kaien never awakened.
Labeled “Codexless,” shunned and orphaned, he remembers only fragments of his past: a burning estate, a bloodstained mother whispering his name, and the words, *“Run, and live.”*
Years later, at seventeen—long after any hope of awakening should have passed—Kaien is ambushed. Near death, something ancient stirs within him.
Not a Codex.
The **Genesis Nexus**.
A relic of a forgotten age. Blank. Hungry. Limitless. It absorbs other systems, devours their rules, and remakes them into something new.
Kaien is no longer Codexless. He is the **Heir of the Nexus**—a threat to the current order, a beacon of an ancient bloodline, and a living weapon forged for vengeance.
Now, he walks a path of cultivation no one understands, claiming forbidden power from every system he tears apart. As secrets unfold and enemies rise, Kaien hunts the truth behind his family’s massacre…
And the god who watches through the Nexus.
