Ten years after the Arkadia system descended upon Earth, civilization transformed radically. Superpowers, monsters, and alien races reshaped society, but extraterrestrial invasion nearly destroyed it all. In humanity's final hour, five thousand Earthlings received an impossible gift: the chance to return to the past. Yet salvation demanded sacrifice. The Descent Clock activated, thrusting Arkadia ten thousand years into the future. These Returners—souls bearing memories of the Origin Timeline—must reshape the past to save an uncertain future. I'm one of them: a villain from that original timeline, now reborn with forbidden knowledge and dark ambitions. In this second life, I exploit every advantage. I orchestrate audacious franchise thefts to accumulate boundless wealth. I hunt notorious serial killers and resolve cold cases that captivated me since adolescence. Where others see moral boundaries, I see opportunities. Time itself has bent to give me a second chance, and I intend to seize absolute power in both timelines.
