On a world much like Earth called Korsuth, humanity broke the secret of imbuing machines with their own intelligence and emotions, creating not an artificial intelligence, but an actual intelligence. While created to serve humanity, those in charge were fearful of a race of sentient machines and so never shared the secret of how the process worked to create more thinking robots, nor the location of manufacture. Despite this, robots were treated more or less as equals among men.
With the machines at their side, humanity was able to colonize the moons, putting permanent settlements on the Arest, and outposts on Unaro, and even putting robotic installations out as far as an asteroid belt. Millions of sentient machines existed among the humans for hundreds of years.
Unfortunately, as all living creatures have their time to exist, they must also pass into extinction. Humanity, already showing signs of decreased fertility, finally came to the point where no more human children were born, and the last generation of man came to pass. A select group of people numbering nearly 100,000 were chosen for genetic health, intelligence, and education, and were frozen in cryo-storage, while the machines were tasked to find a cure or some other answer to bring humanity back into the light of the sun.
Not all has gone well. More than 300 years have passed since the last human walked on Korsuth, and the robots are no closer to solving the problem. In the meantime, a form of robotic civilization arose with it’s own separate nations and factions, and much of the world has returned to the wild with such vast expanses unpopulated by man or machine. Tragically, with no way to replicate themselves, the robots are also dying off as accident, violence, or malfunction dwindles their numbers. The robots are staring down the same failed path that humanity recently trod.
Stepping out into this violent and uncertain world are robots who are finding new purpose from that which they were created originally to do. Most continue in their roles, but some have given up the old ways and seek the answers to the salvation of the two races. Some work to find a cure for humanity, and some search out for the way to create more like themselves. Others wander the planet looking for enlightenment the way the humans of old would often do. All this is to say nothing of those robots who have taken sides in the new nations and continue to fight and defend and engage in conflict over resources or perceived insults. The robots are not much different from humans who gave them life...
This is the future imperfect, where technology is both failing and the only source of survival.
