The new AI devises and implements The Biodome Safety Project, encasing the world's cities in massive domes to protect its inhabitants. Within a short time, the uncertainty of the future seemed to vanish... until the Synths violated their ethical code embracing a new name, the Dark Synths, and revolted against the Terrans.
