Eternal Tevinta

The Eternal Tevinta is a hivemind civilization that is a result of ships full of nanomachines that mutated all the humans into a hivemind collective in a strange galaxy. This civilization wants to assimilate the remaining humans into their ranks no matter what form they have taken in the Poseidon Galaxy.

Big Bang...of Nanites
After the success of evacuating every single human being along with animals and plants from Earth, many fleets have traveled across their Great Exodus to make their way to the Alpha Centauri System when Earth was drifting towards the sun after a major war. Yet along the way, a massive wormhole appeared after spending a 100 years of traveling to their destination. This strange wormhole flung all the flotillas into a completely new galaxy full of strange particles, stellar storms, gaseous nebulae, The Shroud, and many more oddities that make up the Poseidon Galaxy.

In the dark recesses of this galaxy, the Henry Flotilla had something onboard that busted out. The flotilla had experimental nanomachines connected to a main computer AI that controls it. The nanites burst out and started changing humans along with all the particles injected into their bodies while in stasis. As they do, the ships started to crash land onto a planet that orbits an orange sun that had was lush with life. While the people started to mutate because of the nanomachines, the planet had the same fate as it becomes a techno-organic world that is a synthetic paradise and arranged in orderly fashion. The AI has fused itself with the planet after six long years of terraforming and mutating humans into a techno-organic hivemind. Thus the birth of the Tevinta race.

Now, they turn to the stars to colonize the new galaxy and assimilate any other intelligent lifeforms. Even if it means other humans and subhumans.

Government
The entire civilization is governed by a single AI that has rewritten its own directive after much of it was damaged during transit through the wormhole. It's directive is now to assimilate all humans and other civilized lifeforms to guarantee survival and stability for all lifeforms. However, it did assimilated a few other lifeforms in order to add to its arsenal and to help assisting with terraforming regular planets into techno-organic worlds.

Despite being in charge of civilization as a whole, it has supporters called, the Hive Collective, that act as administrators and "sub-systems" that govern the Eternal Tevinta.
