Brute Force takes place in the year 2340, when the human race has spread out across the galaxy and settled around 50 star systems, which are collectively known as the "Known Worlds". The major colonies and some alien races are governed by what is known as the Confederation of Allied worlds (usually referred to as the "Confed"). They patrol borders, protect their people, and keep watch on hostile alien races, as well as humans who wish to work for the aliens. (wiki)
