From the introduction:
A tabletop role-playing game gamemaster can never have too many resources at hand. The intention of this book is to provide a range of options for all gamemasters and dungeon masters and to cut down their session prep time.
…
Each town has a description and several key pieces of information to help you craft your sessions. There is a bit of history, government structure, economy information, imports and exports, population, demographics, businesses, attractions or landmarks, and three adventure ideas.
Equipped with all of these tools, you have everything you need to quickly add a town to your campaign or session.
Be ready when your players leave the beaten track because adventure awaits in every marketplace, alley, inn, and backroom.
