Guildhall Ward

The Guildhall Ward is one of the six wards of Sigil. It's home to artisans and craftsmen, as well as the Transcendent Order faction.
As the name implies, the Guildhall Ward was once home to the headquarters of the guilds, powerful organizations that ran Sigil in the days before the Great Upheaval. After the consolidation of the factions, the guilds' power was usurped. Most withered away, or moved out of Sigil. Without the guilds, the Ward became gradually less distinguishable from its neighbor, the Market Ward, and most Cagers consider them two halves of one whole. For convenience, most residents consider Duskgate Road the informal boundary between the two.

The Guildhall Ward is next to the Market Ward on one side, and the Clerk's Ward on the other. It only had one real "district":

Gymnasium District (the area around the Great Gymnasium) Other than Gymnasium, most of the rest of the Ward was divided up into various racial communities, not due to any edict, but out of a desire for familiar surroundings in a (very!) strange city.
