Society has fallen a long time ago
WWIII begun on the Mayan End of the world, on May 21st, 2012. Every major nation fought the bloody war of Armageddon. China beat the USA to a bloody pulp as payment for it's debt, and conquered the lands of the Red, White, and Blue as interest. Russia began its conquest of Europe under their Putin head, and the ISIS tide clashed violently along the Jerusalem shores. The high and mighty 1% were brought down with broken knees, and the poor rats of the 99% ate their still breathing corpses. Tribal wars sprung anew in Africa, and water drowned the rest, as the ice caps melted, the recently freed waters claiming the land it once own, and the angry sun bat down on the land and heads still exposed. All climaxed in nuclear war, with the radiation cleaning the rest of the filth, known as Humanity.
Roaches never truly go away
Remnants of Humanity were saved by the forward thought of broken governments. Huge Undercities were built, designed to hold hundreds of thousands of individuals in comfort, safety, and well-supply. However, millions poured into these cities like frightened arachnids, and the webs can hold only so many before breaking, no matter how strong they seem. The cities were enthralled in violence, various gangs fighting for limited resources for survival. In the end, many died, but few survived.
The scarred Earth is a living Hell
The radiation has turned the land nearly inhospitable, and the flora and fauna has become more hostile than ever. Rivers of lava flow in magma oases, toxic forests poison all who are not native, and robots gone mad have made massive cities of living steel, and the humans are deemed the most dangerous of all. The land is certainly dangerous, but as I said, MOSTLY inhospitable.
The Wastes are for the Taking
Those who lived in the Undercities have grown tough, and ambitious. They are in no way dissuaded by the horrors of this Brave New World! Onward they go! Like the Lamd Runs of Oklahoma, they rush out their claims, and build whole cities in days! Humanity will not be dissuaded, no! These were His lands before, and the new Manifest Destiny will make it so once More!
