The last of the Free Cities, Darujhistan had been called the "City of Cities". It existed in central Genabackis, on the southern shore of Lake Azur. It was mainly populated by people of Daru and Gadrobi descent.
It was a city built on a rumour. The rumour was that in the Gadrobi Hills to the south there was a great power. Extensive excavations revealed nothing but underground caverns of gas which were later channelled to provide light for the city. (It was the only known city to use natural gas in this way.)
Inland from Gadrobi district's harbor the land rose in four tiers climbing eastward. Ramped cobblestone streets, worn to a polished mosaic, marked Gadrobi district's Trade Streets, five in all, which were the only routes through Marsh district and the next tier, Lakefront district. Beyond Lakefront's crooked aisles twelve wooden gates opened into Daru district, and from Daru another twelve gates — these ones manned by the City Watch and barred by iron portcullis — connected the lower and upper cities.
On the fourth and highest tier brooded the estates of Darujhistan nobility as well as its publicly known sorcerers. At the intersection of Old King's Walk and View Street rose a flat-topped hill on which sat Majesty Hall, where each day the Council gathered. A narrow park encircled the hill, with sandstrewn pathways winding among centuries-old acacias. At the park's entrance, near High Gallows Hill, stood a massive rough-hewn gate, the last-surviving remnant of the castle that had once commanded Majesty Hill.
