Planescape

Lore & 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.

In Their Own Story

The air in Sigil tasted of ozone and old dust as the planewalker adjusted their goggles, staring at the shifting brass door before them. It hummed with a low vibration that rattled the teeth, promising passage to a realm where gravity was merely a suggestion. A hooded figure nearby whispered about the Lady's gaze, warning that stepping through without purpose would result in being cast out into the void between worlds. With a deep breath and a talisman of protection clutched tight, the traveler pushed the handle. The door swung open not to a room, but to a sky of swirling violet clouds, where floating islands drifted like leaves on a river, and the silence was so profound it felt like a physical weight.

Reader's Guide

The geography of Planescape is defined by its cosmology rather than traditional maps. The center of existence is Sigil, located in the Outlands, which acts as the neutral ground where all alignments meet. From here, portals connect to the Inner Planes—domains of Fire, Water, Air, and Earth—and their intersections, creating places like the Elemental Chaos or the Paraelemental planes. Beyond these lie the Outer Planes, arranged in a wheel based on moral alignment. The Upper Planes host gods of good, while the Lower Planes are home to evil deities and demons. Each plane reflects the philosophy of its inhabitants; for instance, the Nine Hells is a rigid hierarchy of suffering, while Ysgard is a realm of endless feasts and battles. Unique rules govern this setting: magic behaves differently depending on the plane, and alignment can physically alter a creature's appearance or abilities. The Lady of Pain enforces strict laws in Sigil, banning certain types of spellcasting to maintain balance. Travelers must navigate these shifting realities using portals that require specific keys, phrases, or items to activate. Major cities include Sigil itself, with its ever-changing districts like the Cage and the Library; Baator's city of Nessus; and Arborea's floating groves. Each location offers distinct challenges, from political intrigue in the courts of gods to survival against elemental forces.
