From the introduction:
Dominating the Land of Lankhmar and crouching at the silty mouth of the River Hlal in a secure corner between the grain fields, the Great Salt Marsh, and the Inner Sea is the massive-walled and mazy-alleyed metropolis of Lankhmar, thick with thieves and shaven priests, leanframed magicians and fat-bellied merchants—Lankhmar the Imperishable, the City of the Black Toga.
Welcome to Lankhmar, the City of the Black Toga and the greatest metropolis in Nehwon. Within the walls of this grand city await a host of adventures, misfortunes, dangers, and treasures for those who are brave — or foolish — enough to seek them out. This supplement is designed to assist the DCC Lankhmar judge in creating adventures set in Lankhmar and to work as an inspirational resource for urban-based adventures. The judge will find a bevy of information about Lankhmar proper as well as numerous tables to help describe the city, kick off adventures, and complicate the lives of the PCs. Although expressly designed for DCC Lankhmar campaigns set in the City of Sevenscore Thousand Smokes, this supplement can also be used for any DCC RPG (and other role-playing games) adventures occurring in a large fantasy city setting.
This book provides the judge with an overview of Lankhmar, giving him a broad picture of the city, its different districts, various civic bodies and trade organizations, and residents of renown. It also contains rules to quickly create unique neighborhoods for the player characters to inhabit and visit.
Section One: A Guide to the City of Lankhmar describes the city overall, presenting the judge with a look at how life operates in Nehwon’s largest metropolis. This chapter details the city’s appearance, its defenses, government and legal systems, organizations, atmosphere, street scenes, and various districts. Useful tables are provided for the judge’s convenience, allowing him to swiftly generate inhabitants, random encounters, adventure ideas, and rumors for the player characters to encounter. While effort has been made to provide the judge with all the basic information necessary to create and adjudicate adventures in Lankhmar, there remains a great deal of blank canvas for him to recreate the City of the Black Toga according to his personal interpretation of Leiber’s work.
