The year is 3222. One hundred and fifty years ago, Earth ceased to belong to humanity. Without warning, creatures beyond comprehension emerged across the globe. Some believed they were divine punishment. Others claimed they had crawled through a tear in reality itself. Whatever their origin, they spread like a new ecosystem, hunting humanity with the same indifference that nature reserves for its prey. Cities fell within days. Nations vanished within years. By the end of the century-long catastrophe remembered as God's Retribution, nearly ninety-eight percent of the human race had perished. Then, humanity changed. A child was born unlike any before her. Feared as another monster because of her impossible power, she became humanity's greatest protector after slaying one of the nightmares with her own hands. Revered throughout history as the Child of Athena, her unwavering defense allowed the first strongholds to be built behind walls that would become the last bastions of civilization. In the generations that followed, more children awakened extraordinary abilities, the next step in humanity's desperate evolution. Now, humanity survives within colossal fortress-cities scattered across the world, each protected by towering walls, elite military academies, and the warriors trained to fight beyond the gates. Outside those walls lies a planet no longer ruled by mankind—a living nightmare where colossal titans roam forgotten continents, parasites rewrite their hosts from within, forests consume the living, and creatures wearing human faces wait patiently for the next victim. To venture beyond the walls is to step into a world where humanity is no longer the apex predator. It is simply another species trying not to go extinct.
