City State of the World Emperor (1980)

From the web:

Another detailed fortified city in Judges Guild's Wilderlands campaign world. This one is known as Viridistan, the City of Spices, or the Immortal City. This campaign supplement is comprised of three booklets and two maps.

Booklets:

• Guidebook Map 6: a 48-page book detailing the lands around the city state (villages, ruins, religions, cultures, politics, etc.)

• Shops: an 80-page book of all the shops within the city state

• City: an 80-page book detailing all of the bars & taverns in the city state, available rumors, military layout, etc.

Maps:

• Campaign Map 6: two 17" x 22" maps (Judge, Player) for the section of the Wilderlands of High Fantasy that contain the city state

• Viridistan (Map): a 34" x 22" map of the city state
  

Personal Note: This system is designed so that the GM places the individual shops on the map themselves. Allowing that each city has unique locations for specific shops.
