Sigil is the "City of Doors," located atop the Spire in the Outlands, shaped like a torus with the city built on the inner surface of the ring. It can only be entered or exited through magical portals, which is why some call it "The Bird Cage" or "The Cage."
Fifteen philosophy-based factions controlled the political climate of Sigil before the Faction War. In 1998, TSR published the Faction War adventure, instigated by Duke Rowan Darkwood, factol of the Fated, which ended the factions' hold on the city.
The Great Wheel is the cosmology of planes used in Planescape, originally developed in the 1987 Manual of the Planes by Jeff Grubb and derived from concepts in Gary Gygax's 1978 Player's Handbook. It organizes existence into the Inner Planes, the Ethereal Plane, the Prime Material Plane, the Astral Plane, and the Outer Planes.
Planescape: Torment is the computer game based on the Planescape setting, portraying locations including Sigil, the Outlands, Baator, Carceri, and the Negative Energy Plane. An enhanced edition by Beamdog was released on the 11th of April 2017.
