Planescape

Lore & Background

In the Planescape cosmology, the planes of existence are not merely locations but expressions of thought, faith, and philosophy. The City of Sigil, a vast metropolis of iron and stone perched on the Material Plane with a single colossal gate, serves as the crossroads between all planes. Here, the Outdoors sprawl beneath, the Underdark coils above, and the city itself is a palimpsest of every plane's influence layered over the others.

Planescape: Torment transposes this cosmology into an interactive narrative. The player assumes the role of the Nameless One, a character who has died and been resurrected nine times, each life erased from memory. The game's world is populated by companions and antagonists whose motivations are shaped by the Planar philosophy: a being's nature is defined not by class or race but by what they believe and how they act upon it. The central question—what does it mean to be a self, to carry a soul, to choose identity—threads through every conversation and choice.

The setting's broader D&D lore, established by TSR in the 1990s, introduced concepts such as the Lady of Pain, the Gate, the Factories, and the various planes (Astral, Ethereal, Mechanus, the Abyss, the Nine Hells) as a coherent metaphysical system. This gave the game a philosophical scaffolding far more intricate than a typical fantasy backdrop, allowing its writers to explore free will, determinism, and the nature of the soul with a specificity that few other games have attempted.

In Their Own Story

The rain in Sigil does not fall so much as it is remembered into existence by the clouds, which are themselves arguments made visible. You stand in the Factory of the Lady of Pain, watching the gears turn in silence, each one a life you once lived and no longer recall. A voice from the other side of the gate asks your name. You open your mouth. The name that comes out is not yours. It never was. But it is the only one that fits, and so you wear it like a coat that is slightly too large, walking back into the Outdoors where the sky is a ceiling and the ground is a floor and everything in between is a question you have been asked nine times and never once answered.

Reader's Guide

Planescape: Torment emerged from Black Isle Studios, a team already known for Baldur's Gate, which had demonstrated the commercial and critical potential of the Infinity Engine. Rather than replicate that formula, the designers chose to subordinate mechanical progression to narrative depth. The party system, while functional, was deliberately secondary; the true engine of the game was a dialogue tree of extraordinary length and philosophical density, drawing on literature, religion, and existentialist philosophy.

Historically, the game arrived at a moment when the CRPG genre was still defined by combat grids and stat blocks. Planescape challenged that definition by making the player's choices about identity and belief the primary progression. The setting itself, inherited from the D&D Planescape campaign books, provided a ready-made metaphysical framework that allowed writers to treat abstract concepts as tangible locations and adversaries.

Its influence on modern storytelling in games is difficult to overstate. Titles that prioritize character-driven narrative, moral ambiguity, and dialogue as a core mechanic—BioShock, Disco Elysium, The Witcher 3's character moments—can trace a direct lineage to the design philosophy Black Isle pursued. The game also demonstrated that a single, deeply written protagonist could anchor an entire RPG without the player needing to project themselves onto a blank slate, a design choice that would become more common in the narrative-advanture era that followed.
