The Hub is a major trading city in Fallout. It is a large community of traders, barterers, gamblers, and other interesting scum. The Hub is a stopoff point for caravans north to Shady Sands and Junktown and south to the Boneyard. The wide variety of people passing through ensures that there is always something interesting going on.
The Hub was founded in 2093 by a man named Angus, who set up camp around a filthy oasis in the desert, and proceeded to begin trading with other settlements. In 2096, a man called Harold rose to the level of a caravan boss in the Hub. His caravans suffered occasional attacks in the wastes, but Harold's caravan outfit survived and prospered... until the mutant attacks begin to pick up a few years later.
