The year is 22XX. The Resource Wars are over. The European Commonwealth is over. The Great War is over. They first brought Europe first to its knees, then buried it six feet under, filling the grave with division and death.
European civilization is not just lucky to have survived, as is the case with American civilization. It survived only due to the ever increading irrelevance of a shattered Europe tearing itself to pieces years before the bombs fell, resulting in not quite enough bombs being dropped to cause extinction. Of course, people living in rural areas and in vaults (either international vault-tec or something else, left vague for now) helped.
Our tale takes place in the heart of Europe. What used to be proud Europeans have now forgot parts of their history altogether, seeking to follow different ideologies or looking up to ancient governments. For while survival is often just as hard here as it is in America, self-proclaimed empires and republics still exist, often submerging themselves in bloodbath.
Because war, war never changes.
