Cyborgs where all human to begin with.
Asteroids. They mined them, took all the minerals. With nano machines, with mining droids, and Cyborgs.
They started as a medical thing. A way of helping. Then after the war of 2067 they where a mechanism of war. Humanity had destroyed a lot of itself in the war and Earth was at a state where a Ice Age was imminent. They sent Cyborgs out to claim territory in space. With weapons.
First they destroyed those who had come before. Then they mined the minerals and took them, back to Earth.
This did not last.
The Cyborgs were controlled by the SolaraNet which was in turn controlled by two corporations and public interest. In turn the corporations went bust. No one is entirely sure why now, just they did. Leaving the now mostly singular Earth government in charge of the Cyborgs. This was then a problem. Each Cyborg had been, or was a human to begin with.
This meant when one killed it was still guilty of murder.
When one worked it was still paid.
And most of all they where no longer a he, or she. They where an it.
Cyborgs did not like this at all.
The war was short but rather eventful, the Humans sent a ship. The UPA Juggernaut. The Cyborgs hit it with a 300 meter long asteroid.
It flew right into the middle of the ship. No one survived.
But then the Cyborgs reanimated the humans aboard, giving each a very small Cyborg implant that allowed them to access the SolaraNet. This was or seemed odd until the SolaraNet was taken over by a series of powerful AI. Ones the Cyborgs had programmed. The press called it DarkNet. The name stayed. The new Cyborgs, some returned to Earth, others stayed in the stars. All had earned the Freedom to be. A new race and a new chapter if humanity. Soon terminals everywhere could access the DarkNet and people began to truly colonize space beyond the Asteroids. Then something really odd started happening.
People where born with the ability to access the DarkNet. As if it was genetically determined. It really freaked the scientists out.
But then there was another War. One no one had seen coming.
