From the back cover:
Exciting adventures in the City of Brass and other genie lands!
Revealed within are the greatest secrets of the genies: their magics, their rulers, and their homelands. From the Citadel of Ice and Steel to the Great Dismal Delve, the works of geniekind are as wondrous as they are magnificent.
Tour the City of Brass, from its golden towers to its brazen streets, foil the evil yak men and their dao servants, travel on the desert whirlwinds of the jann. Learn the legends and secret history of the genies, their cities, their foibles, and their feuds.
Secrets of the Lamp includes a 64-page sourcebook about genies, a 32-page booklet of adventures set in Zakhara and the City of Brass, a full-color poster map, six cards showing details of the city, and four MONSTROUS COMPENDIUM(TM) pages that introduce new genies and other elemental creatures.
