Hovering in the hottest areas of the Plane of Fire, the City of Brass sits in an enormous hemisphere of brass some 40 miles across. A curtain of beaten brass surrounds the entire city, stretching for hundreds of miles and giving the city its name. However, since the brass hemisphere gives the city its ability to fly, these impressive walls are typically unmanned. Throughout the cosmopolitan city, the dangerous fire effects of the Elemental Plane of Fire are suppressed by the will of the Grand Sultan in an effort to foster more inter-planar trade. Despite this, the city itself has a hindering effect on those of good alignment, due partly to the nature of the efreet but also to the numerous connecting portals with Hell.
Surrounding the city itself are large tracts, known as the Obsidian Fields, used for the cultivation of the exotic crops that inhabited the plane of fire. Examples included qamah, habbat, verdobba, umbelin, tergamit, and fireweed. There are also areas for slaves to mine tin, copper, and diamonds for their efreeti masters.
Throughout the city the common efreet and their slaves have their own houses. The houses of noble efreet, on the other hand, teemed with servants and easily doubled as small fortresses. The City of Brass is illuminated primarily by the ambient light from the Sea of Fire and fiery canals that inter-cross the city and provide a dim red glow throughout. This is supplemented by intermittent pots of unquenchable elemental fire that hangs along the streets. Efreets traverse the Sea of Fire and the city's canals through use of barges and galleys that are made of magically enchanted brass.
The Furnace This is the core of the city and where the Charcoal Palace of the Sultan resides. The other districts of the city surround the Furnace in ever widening circles.
