The United Planetary Federation, often simply abbreviated UPF is the extra-national organization that protects the Frontier Sector from outside aggression, and functions as a forum for resolving altercations between its member planets.
It is governed by the Council of Worlds, composed of delegates from each member planet, as well as observers from the most powerful mega-corporations. It funds and controls Star Law, which fights crime outside the jurisdiction of its member planets, and Spacefleet, the most heavily armed force in Frontier space, to defend both against Sathar incursion and pirate attacks. They also run the Planetary Survey Administration, who explores and surveys unexplored system and planets. The PSA was greatly expanded after the events that lead to an anti-Sathar rebellion in the Liberty system. From this, the Frontier Expeditionary Force was formed. The UPF Security Council is another key body of the UPF.
The UPF’s jurisdiction does not extend to the surface of its member planets, only to orbit. It is also not allowed to influence or manipulate a member government, thus its members range from utopian democracies, to corporate worlds, all the way to totalitarian dictatorships and criminal-ruled near-anarchies. The UPF and its agents are free to make contact, trade, and help primitive civilizations, usually to protect them against the Sathar.
After the Pyrrhic victory of the Second Common Muster, by Admiral Morgaine in the First Sathar War, the Council of Worlds formed the United Planetary Federation to deal with the appending treat of the mysterious Sathar race. At first, they where small and weak do to the lack of available warships after the Second Common Muster, and had to make do with privateers and yachts. The fledgling UPF put a lot of money into the research and development of modern warships, and it took time to finally field such craft. Some 80 years after the “Grand Meeting,” the Sathar fleets returned with a vengeance, and this time, the frontier was ready. So began the Second Sathar War.
The UPF Fleet fared better than the Second Common Muster, but they came out victorious with a sizable force to repel a counter-attack. Production of new warships grew during the war, and continued for years after, with newer ship classes replacing older ones in the three main Fleets.
Eventually, as the Council of Worlds became a major government in the frontier, the UPF became the primary military force within the frontier and many of the local militia fleets were absorbed as Planetary Guard fleets.
