Sigil

Sigil is a huge city at the center of the Outlands (the plane of Concordant Opposition). The city is shaped like a torus with a small break along the inner edge.

Directions in the city are given in relation to a geographical feature called the Ditch. The Ditch is a ravine with a large river running through it. The river flows towards the edge of the break in the torus. Citizens of Sigil refer to "upstream" and "downstream" to orient themselves (or somethings simply "up" and "down", using the flow of the river as a reference. When one is facing "upstream," one can further orient oneself by referring to "clockwise" and "counter-clockwise." So one might give directions by saying, "walk upstream for 2 blocks, then turn clockwise and walk for 3 blo

Sigil is divided into six districts, called wards, listed below:
 * The Clerk's Ward, an affluent district, home to most of the city's lower-rung bureaucrats and middlemen.
 * The Hive Ward, the slum and the ghetto, home to the poor, the rogues, and the unwanted dregs of the city.
 * The Lady's Ward, the richest and most exclusive section of the city, is home to the elites of society and of its government.
 * The Lower Ward, an industrial district, clogged up with the smoke from the foundries and from the portals to the Lower Planes.
 * The Market and Guildhall Wards are the home to the traders, craftsmen, artisans, guild members and other members of the middle class.

The city is currently in the middle of an invasion by the Grand Army of Revolt. The Army controls nearly a third of the city.
