In 2049, a catastrophe known as the Day the Gods Fell descended without warning. The sky shattered, and beings who called themselves the Creator Gods set foot in the mortal world. They were not the benevolent creators of legend, but predators who fed on human civilization, regarding humanity as inferior meat and expendable slaves. The old order collapsed in an instant. Cities became ruins, and the population plunged by ninety percent. Some survivors awakened all kinds of strange abilities, but most were feeble and no match for the gods and their armies of servants. Humanity was penned up in vast cages called "Sanctuary Zones," forced to pay tribute regularly just to eke out a miserable existence. The world was shrouded in despair and divine might, while the spark of civilization flickered on the verge of going out. The gods' true purpose and origins, meanwhile, lay hidden behind endless mists and lies.
