April 4th, 1968. A dark day that will be forever known as the "Day of the Dead". At exactly 2:13 PM, the Venus probe that had been sent out one year previous returned to our atmosphere, carrying on its shell the greatest plague known to mankind. The probe was set to touch down in an undisclosed location. The world was almost destroyed as a result. The atrocities of ten years subsequent fighting had left the world scarred and decimated, and the faint glimmer of light that was the spark of earthly sapience was almost extinguished. Nobody had ever suspected such a thing would happen...again.
