Seven Cities
A D20 System fantasy sourcebook for creating and running populated settlements, from small thorps and hamlets to large cities. It provides maps, histories, geography, commerce, politics, power centers, and distinctive inhabitants whose relationships and conflicts support adventure. An introductory section explains how to design original communities, while seven settlement chapters present ready-to-use locations. Characters and story elements recur across settlements of different sizes, allowing individual communities to be used separately or combined into a connected setting.
