Like the gold rush sent Americans to the wilderness to seek their fortune, once the stars were in reach humanity spread across the Belt and beyond for similar reasons: the hope of a better life and a better future. The hundreds of small settlements, stations, and ships that form the Belt were built at the same time as the shipyards, bases, mines, and farms of the Outer Planets. Though Belters are considered the heart and soul of the OPA, it was named the Outer Planets Alliance for a reason. The Inners have even gained control here, in the deepest, furthest reaches of the solar system. The major moons of Jupiter and Saturn have fully functioning settlements on them, some protected by UN and/or MCRN ships and troops, the extent determined by strategic and economic importance. The Jovian and Saturnian Systems are so large and well-populated that they could be almost be considered tiny solar systems of their own. The Uranian and Neptunian Systems are far more sparsely populated, and often ignored by the Inners unless it’s time to collect tariffs or taxes. Though not actually within the Belt, these systems are considered to be a large part of it—and their inhabitants have similar concerns and complaints.
