Sigil (Dungeons & Dragons : Planescape)

Sigil (pronounced: /ˈsɪgɪl/ SIG-il[9]), also known as the Cage, the City of Doors, or, less commonly, the City of Secrets, was a floating city in the center of the Outlands and the self-proclaimed center of the multiverse in the Great Wheel cosmology. A major hub for interplanar travel, the city contained multiple portals to every single plane, as well as to numerous locations in the Prime Material Plane. It was considered a demiplane in the World Axis cosmology.

This city has more political intrigue than Waterdeep, the people are more arrogant than Westgate merchants, and the air's more foul than a Zhentil Keep sewer.

Forjada por fuego, sangre y metal, por elfos enanos en minas, su hoja afilada es un arma letal, abre latas de sardinas, unta paté en pan integral, útil también para cortar salchichón o las uñas de los pies. ¡Por los dioses del fuego eterno! mejillones en lata abrirá.

Sigil was shaped like the inside of a torus. According to official measurements by the Harmonium, the city's primary diameter―that is, the ring's diameter―was 5 miles (8 kilometers), with a circumference of 20 miles (32 kilometers)

The city did not fill the entire inner surface of the torus, but just the outer portion of the ring. For that reason, the city was recursive only in one direction, along its major circumference. Even though it was not a completely closed surface, it was impossible to see outside of the ring from any point within the city.

The only way in or out of Sigil was via its innumerable portals. Any bounded opening (a doorway, an arch, a barrel hoop, a picture frame) could possibly be a portal to another plane, or to another point in Sigil itself.

The ruler of Sigil was the mysterious Lady of Pain, who reigned from her seat of power known as the Throne of Blades. Her power controlled all the portals in the city and prevented all deities and archfiends from entering it.

Although the Lady of Pain did not act directly in the everyday management of Sigil, her will was enforced through a number of servants known as dabus, who simultaneously served as the Lady's eyes and ears as well as keepers of the structure of Sigil. Like the Lady, the dabus did not interact much with Sigil's inhabitants or travelers.

Hice: Barrio pobre
Mortuario: Gigantesca morgue donde se entierran los muertos
Comercial: Distrito donde están los centros comerciales. La esclavitud como castigo es real y se subastan aquí.
Centro: Distrito donde vive la elite
Alcantarillas: Ruinas subterráneas. Las ratas cerebrales luchan una guerra secreta contra la nación de no muertos.

Thanks to the Lady's strict forbiddance of open large-scale conflict, Sigil was a true neutral haven to all visitors. It was a location where no wars were waged and even the fiercest opponents, such as an angel and a fiend or a devil and a demon, could be seen sharing a drink and momentarily setting their differences aside.
Nevertheless, Sigil was hardly peaceful; the Lady of Pain did not concern herself with day-to-day crime such as murder or petty theft.
