Planescape

Background

The foundation of Planescape rests on the concept that thought, emotion, and belief are tangible forces capable of manifesting physical realms. The multiverse is structured as a Great Wheel, with the Material Plane at its center, surrounded by the Inner Planes of elemental energy and the Outer Planes of moral alignment. Between these lie the Ethereal and Astral planes, which serve as conduits for travel. This structure dictates that a creature's soul journey after death depends entirely on their alignment in life, drawing them toward specific Outer Planes.

Sigil, often called the City of Doors, floats within the pocket dimension known as the Outlands, serving as the neutral crossroads of the multiverse. It is ruled by the Lady of Pain, an enigmatic and terrifying entity who maintains order through absolute neutrality and the prohibition of magic that challenges her authority. Within Sigil's walls, thousands of factions vie for influence, each representing a different philosophy or obsession, from the chaotic freedom of the Fraternity of Order to the hedonistic pursuits of the Xaositects.

Travelers in this setting are often referred to as 'planewalkers,' individuals who have mastered the art of navigating these diverse realms. They utilize portals that can open anywhere at any time, connecting disparate worlds in ways that defy logic. The atmosphere is one of constant wonder and danger, where a simple conversation might reveal a god's true nature or a marketplace might sell memories instead of gold.
