From the publisher:
City Builder Volume 6: Mercantile Places is the sixth offering in a series of 11 complementary books designed to help guide Game Masters through the process of creating exciting and compelling urban areas and places within them for their campaigns. It is a universal resource that is not specific to any particular game system and is intended to be compatible with the needs of almost any ancient, Dark Ages, Middle Ages, Renaissance, or fantasy milieu.
Its contents include:
An Introduction that describes the scope of the series and how to use the material in this volume;
Sections devoted to descriptions of Banks, Brokerages, General Stores, Marketplaces, Pawnshops, Trading Posts, and Warehouses; and
One to three Adventure Hooks tying in with each described sort of place.
