Fiction:Allied Space Empire

A powerful empire without any Goverment. Not much at all is known, but it is so powerful, it's miltary is one of the strongest in the universe, yet it is a religious empire! It is thought that by tribal stage, they had space ships. This seems impossible, yet theory is that they were in tribal stage for 120,000,000 years. So civilization would be galactic stage, maybe. Although the Exactamondo do have technology that can go through different universes in clicks of a button, so the space ship travel radius is infinity. Probably. No more info is publicly known.
