Sigil

The City of Sigil
Sigil (pronounced /'sɪg.ɪl/), also frequently known as the Cage or the City of Doors, is a city-state and the supposed center of the multiverse which includes the Prime Material Plane and all other known planes according to some forms of the Great Wheel cosmology. Sigil is connected to all times, spaces, realities, states of mind, being, and concepts that exist. One walking down the Main Avenue of Sigil could see any number of incredible or downright unbelievable creatures, from representations of emotions in the form of raging flames or weeping rain clouds to fictional characters from film, literature, and video games, and even real people from history, modern day, and the future split from any number of reality.

Sigil is divided into 6 wards:
 * 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 of Sigil varies in renown from reality to reality. In some realities, Sigil is extremely famous, with its residents being celebrities, while in other realities Sigil is not even known about, with the idea of multiple realities being a foreign concept. The GM of the UGWL, Skyrocket, is very knowledgeable in the arts of portalmancy, and as such has gathered a freakish hodgepodge of talented wrestlers from all realities, making his wrestling promotion the most popular in the city of Sigil, with UGWL shows being sold out on every night of their appearance. The fluid nature of Sigil's reality makes guessing when the next show will be a challenge, but Skyrocket can generally give a relative time of when the show will occur. The UGWL arena resides in the Clerk's Ward, with the dome of the arena being a relatively noticeable landmark.
