In 2025 a virus called HTAV-5 was created. Nicknamed "Zero Day 5" it was a new super virus that was developed to carry cures for Ebola, Covid-19, and others. However, it mutated and escaped from the lab. Heavier then air, air borne, and highly contagious, it swept the planet in a rush of death. This was a generation that had survived the Covid epidemic, but we were still hit hard. Millions died. To escape what was going to be the death of mankind, governments started building what would come to be the great "AirCities". Seven major countries, seven AirCities. Other countries either had to join or die. Some decided to join and hope for salvation, others refused and tried building their own. Many of these failed, to great loss of life. This was the beginning of a new era. The beginning of the AirCities.
