Trading posts (synonyms: stores, markets) are locations where a vendor buys and sells goods, either with a currency or via the barter system. They may be part of a fort. In game worlds these may be locations where players can exchange items they have obtained and/or purchase equipment. Trading posts tend to be located in remote areas and may be important parts of the local economy. They may be an integral part of a trade route for a high sought-after trade good (such as furs, rare gems, or spices). If the trading post also sells tools and/or services, it may also be an outfitters.

When designing trading posts consider what their primary goods and services are. If they purchase fish, there may be traps and nets nearby. If they deal in rare gemstones, there may be security measures in place.

Trading posts are an opportunity to explore both fictional materials and fictional corporations.
