“Some call Sigil the City of Secrets, because everything that can be known is known somewhere in its twisting streets. Some call it the Cage, because it’s hard to get to and hard to leave. Mostly it’s called the City of Doors, thanks to the portals that connect it to the rest of the universe, like the hub of an enormous web of relationships and connections.
A few wise souls like to think of Sigil as the microcosm—a tiny reflection of everything that is, everything that has been, and everything that yet could be, represented in the form of an enormous planar metropolis.
Sigil is a plane unto itself, existing outside the ordered structure of the rest of the universe and yet intricately connected to it through its unnumbered planar portals. It’s a filthy, noisy city with smokechoked alleyways and crowded streets. The city is built on the inside of a gigantic, hollow ring that has no outside. To its citizens, though, it’s the center of the universe—vibrantly alive, full of every imaginable treasure.” - from the Manual of the PlanesSigil is divided into six districts, called wards:
- The Hive Ward, the slum and the ghetto, home to the poor, the rogues, and the unwanted dregs of the city.
- The Lower Ward, an industrial district, clogged up with the smoke from the foundries and from the portals to the Lower Planes.
- The Clerk’s Ward, an affluent district, home to most of the city’s lower-rung bureaucrats and middlemen.
- The Market and Guildhall Wards are the home to the traders, craftsmen, artisans, guild members and other members of the middle class.
- The Lady’s Ward, the richest and most exclusive section of the city, is home to the elites of society and of its government.
