I had an idea for a back story about the Nomads: The Nomads The nomads were originally human beings. They were part of a project consisting of sending fleets of ships carrying colonisers to one of the rare the rare planets which had been considered inhabitable. To allow the computers of the different ships to stay coordinated they would need to transmit information. But experiments proved that in hyperspace it was nearly impossible to transmit information. The scientist came up with the idea of using the human mind as transmitter. To accomplish this they devellopped Neurolium. This drug would inhance the psychic capacities of a person and allow her to communicate using her brainwaves. Thabks to Neurolium, while the crews of the ships would be in stasis the onboard computer would use their minds as a relay to communicate with the rest of the fleet. With only little testing the ships were prepared and sent onto their trip to another world. In their haist to conquer hyperspace the scientist had over looked the main problem of Neurolium, it was a highly addictive drug and once addicted the consumer risqued death if e did not receive a regular dose. Not only this but Neurolium also caused genetic damage if taken in great quantities. Once the ship arrived at destination, codenamed Alpha Prime, it was not the same people who disembarqued. After generations of execive drug consumption and genetical decadence those who had left earth were hardly what you could call human. But the Neurolium did not have only disadvantages. It also caused the peoples minds to devellop beyond normal human capacities. This way they quickly discovered that they were doomed if they could not stop their decadence. They managed to find a way to control the evolution of their ADN. The Nomads started building massive space ships to welcome their ever growing populatioon. They moved from star system to another, slowly expanding their empire. Many civiliations fell under their iron heel and finished by disappearing. The Nomads do not know were they go, they only know that their origins are somewhere in the Galaxy and they would crush anybody who got in their way. What do you think?
