Remnants

In 2015 AD, the UN approved of a worldwide activation of a machine that would generate unlimited, clean energy that would be distributed to everyone via airwaves. A few people opposed this and some even moved underground. They only became right when there was a miscalculation: Once the machine was turned on, everybody's brain got "fried" and almost all human and animal life died. Those underground who were smart enough to install the proper "shielding" in their habitats survived. They had to stay underground and outlast the Energy Generator. They finally got out after 52 years when the machine finally stopped functioning due to lack of maintenance. A new form of government was formed around "Lawbringers", "Relic Tecs", "Gatherers", "Traders" and "Hunters".
