Ten years of patience: orphan Grey joins the Holy See's Dragon-Slayer Legion to avenge the adoptive mother killed by a black dragon — only to unearth the lie. A thousand years ago, the dragons sealed the Abyss with their own bodies; now the Holy See slays them to break the seal and harvest Abyss essence to feed a false god. As his dragon-slaying blade drains his life and Saint Lia's sacrificial mark burns red, Grey awakens with snow-white hair, tears down the Holy See, and seals the rift with his own petrifying body — only to return through the Watcher's mark and crown a new era where humans and dragons stand guard together. But in the night sky, the golden eye of the god realm reopens... the next harvest is coming.
