Freighter fuel and supply depots are scattered throughout known space, often run independently by familys or small companies, they are usually found along long traderoutes and frontier zones where ships will need fuel and other supplies. They carry food, oxygen scrubbers, medical equipment, water, antimatter and Helium-3, as well as small restaurants and bars, and luxuries that spacers rarely get access to on long voyages, including "companionship" and even showers that use real running water. These facilities are often just a part of a much larger company that mines materials throughout a vacant solar system and then sells them to long-range ships. While typically unarmed, they usually have a squadron of fighters or are attended by patrol corvettes.
