On what began as an ordinary day, the world changed irrevocably. There were no signs, no warnings, the civilization everyone once knew plunged into chaos when all of the human on earth suddenly disappeared one day. People who had once lived comfortably in the safety of their homes now faced a grim reality, power became the only thing worth clinging to as it's the only thing that could ensure one's survival in a whole new world filled with danger. The weak preyed upon, their cries for help lost in the cacophony of a world turned upside down.  The world had changed and there was no way of going back, the old rules no longer applied anymore in this era since survival was the only law and power the only currency.
