The Milky Way galaxy. It seems to calm, yet that is far from the truth.
As interstellar nations loose sight of the devastating invasion at the Milky Way by extragalactic entities, as that history is lost in the seas of history, down the deepest ravines, rivals now seeks to defeat each other while others ally and unite. A prominent alliance between the Dolmholdi Collective and the United Earth Federation of Planets seems to be making progress, but so are the rest of the nations. Minor wars, such as border wars, seem to be erupting more and more frequently, especially among the smaller nations, while superpowers jostle with threats increasingly often.
What make of this galaxy? It is up to your nation, and your people.
