The world of Carbon 2185 is that of our own, and up until the end of 2018 follows our own timeline and history.
2019 - 2030
Between 2019 and 2030, the earth's climate continued to degrade, and the wealth gap continued to grow, causing widespread famine and political unrest. Despite this, many cities and companies thrived economically. Musk Interplanetary made huge strides in space exploration, and despite delays, successfully landed humans on Mars on March 15th of 2030.
2031 - 2080
The continued refugee crises, and weakened economies across the world, as well as the world's supply of crude oil running dry saw this time, which should have been a golden age in Earth's history, become a time of civil unrest and broken alliances. Shenzhen Solutions famously develop the world's first Neurolink in the early 2050s. By this point, the megacorporations had gotten a hold of the planet, and are unwilling to let it go.
2081 - 2130
The assassination of the President of the EU on May 2nd 2081, followed by the May 7th assassination of the President of the USA saw the weakened and panicked governments of the world usurped by the megacorporations waiting in the wings.
The continued environmental collapse was now in full swing, with entire swathes of land becoming uninhabitable and inhospitable.
The following 50 years saw huge advancements in technology from the megacorporations who were now free of government restrictions.
More importantly it saw Nightingale Exploration, develop the first ever Synthetic human, known as a Synth. These Synths have biological bodies, but incredibly complex AI, and more importantly for the megacorporations, they have no legal rights.
2131 - 2185
Everyone seems to be used to the way things are done now. It's been over 100 years since the megacorporations wrestled control from the governments, and since humans shaped the world into a dystopian nightmare.
People do as they always do, they try and survive.
