Patrol, trade and Xboat routes are the lifelines of the Imperium, and starports are the anchors to which they are tethered. Serving as trade centers, customs offices and outposts of civilization in far-flung systems, they play a central role in the lives of starfarers, and are a crucial source of goods, wealth and information for even the most planetbound of souls. At the same time, they are havens for smugglers, fugitives and black marketeers. Starports classifies standard starports and describes their facilities, organization and functions. It includes examples and plans, and guidelines for starport adventures and encounters. It is designed to complement Far Trader and the upcoming Starships supplement.
