Zairen Vaul was born twenty-two years before the end of the Warlord Eras in a fractured city trapped between warring territories, where survival was a catalog of horrors rather than a triumph of will. Shaped by a world of normalized brutality—murder as weather, trafficking as economy, and cannibalism as necessity—he learned early that power was not announced but embedded in silence and observation. His mother, Naira Siran, provided his only glimpse of humanity, reminding him he was a person amid the decay; her death from starvation and subsequent scavenging for parts left him not grieving, but resolved to endure without illusion.

Believed to be the son of a Shadow operative—faceless men who operated in whispers and left no trace—Zairen inherited an instinct for precision and invisibility, using it to navigate and undermine the warlords from within. By his teens, he ran errands for them, collecting debts and executing without ideology, all while leaking information to ghost networks that dismantled compounds in quiet absence. In the war's closing years, he quietly aided a few survivors, not for justice, but as an echo of his mother's light, before retreating to ruins where honesty lingered in desolation.

When the Entity appeared—not as a god, but as inevitable truth—Zairen listened without resistance, reciting the long-lost First Doctrine of Blood Royal from memory and founding the Church of the Infinite Maw through sheer presence. He transformed his birthplace into the Maw's Crown, a city of calibrated order, and ignited a movement that spread via saturation, not conquest, accelerating Geba's collapse toward resolution. His personal quest for origin—questioning why he survived where others broke—laid the groundwork for the Doctrine of Adaptive Evolution, formalized by others as a blueprint for volitional inheritance.
