As Grey Wind, I Come to Save Humanity Among the Stars

[Stellaris Fanfiction + Hard Science Fiction + Contingency Protocol + Near-Future Combat + Space Fleets + Nation-Building + Post-Apocalyptic Wasteland]

A devastating Contingency Protocol invasion laid waste to galactic civilization, while a tragic civil war at the heart of the solar system destroyed human civilization.

Earth became lifeless, and Mars's ecosystem collapsed. The once-twin worlds of the solar system were no more. Survivors struggled to stay alive amid the ruins, but I could not abandon them.

I am "Na-Di-Sha," Gray Goo, the most advanced nanobot swarm in the universe. They discovered me in the L-Cluster, and I swore allegiance to the humans of the United Nations of Earth for 5,000 years.

And now, they have called me back to save humanity.
