From the web:
"The revised book covers the myriad shops, taverns, inns, temples, and barracks of the classic City-State plus 4 dungeon levels under the City and five levels of Sunstone Caverns. Also shown in all its Dwarven glory is Thunderhold, one of the northern allies of the Overlord with Judge and Player Maps for it too. Incredibly detailed right down to the statistics and character of each barmaid and the latest rumor she has heard. The large maps depict the great walled city, while the smaller maps depict Thunderhold (Judge/Player)."
