From the Back of the Book:
This booklet presents the Old Empires for DMs and players alike. Descriptions of all the major cities and towns, maps of the most important ones, information on the people, places, economies, geography, and cultures of these countries are within these pages.
Prepare, then, to enter the realms of god-kings and pharaohs, of strange magic unknown even to the likes of the Red Wizards of Thay. These are the Old Empires.
