Terran Federation Colonies

In the future, after the first contact with a more evolved species of humans, new habitable planets are discovered. Humans colonize them and fight several species of aliens to keep them and to conquer new planets.

By 2154, the entire humanity will have been unified under the Terran Federation, with capital in Washington D.C., Earth (Terra), the successor of the United States. All republics, monarchies, and theocracies will have joined.
