The drifa cataclysm of 2054
In the year 2042 an asteroid estimated to be roughly the size of Seattle was spotted on a direct collision course with Earth within 12 years. It hit the Pacific Ocean during the summer of 2054 with catastrophic impact.
Over 3.9 billion people across the globe were later recorded to have been wiped out in a single day. Another estimated 700 million perished over the next half century of environmental aftermath.
The end of human civilization had come.
But within the 12 years before the asteroid dubbed Drifa collided with the Earth, a dire race against time sparked rapid technological development and advancement.
All companies involved in the use and development of technology were merged by mandate of the One World Government in an effort to circumvent the crisis. They were tasked with creating an environment capable of withstanding the aftermath of “Armageddon” and sustaining human life.
These parties consisted of a vast amount of industrial, medical, agricultural, economical, ecological, architectural, technological, and even militaristic authorities who led research and development teams with extensive experience in every subject of construction. Even companies that developed video games were largely involved in conceptualizing much of the structural aspects and practical interfacing of the civil functionalities of the Biomes.
500 city-sized, climate-controlled environments based atop artificial landmasses were erected across the United States. Other countries devised and implemented similar and derivative methods to sustain their populations. They were dome shaped ergonomic habitats that operated to astonishing efficiency, featuring interchangeable modes to pull energies given from wind, water, solar rays, lunar radiation, heat, and cold. However, space was limited within the Biomes.
Thusly, cities were constructed along the radius of many of the Biomes. This allowed them to benefit from the massive energy stores. Regardless, many died in the aftereffects of the Drifa Cataclysm. However, not all traces of human life outside of the domes perished. The cities constructed along the radius of the Biomes are largely still functional, having been built upon the extended roots of the incredibly resilient Biomes.
These areas are known in present day as Frontier Cities, and some boast comfortable populations as large as 800,000 with living conditions slightly above mid 21st century standards.
Circa 2100, in the beginning of the 22nd century, the Earth's population is largely pastoral. Many, many miles of dangerous roads, ruins and glowing craters now lie between areas of dense population. The outcome has essentially thrown these parts of the world into a new “Wild West” era and made simple land travel between cities a riskier endeavor than any other.
