"Dominating the Land of Lankhmar and crouching at the silty mouth of the River Hlal in a secure corner between the grainfields, the Great Salt Marsh, and the Inner Sea is the massive-walled and mazey-alleyed metropolis of Lankhmar, thick with thieves and shaven priests, lean-framed magicians and fat-bellied merchants - Lankhmar the Imperishable, the City of the Black Toga."
