Development , 1761. One of a series of etchings that inspired the visual look of the setting.
Planescape is an expansion of ideas presented in the
Advanced Dungeons & Dragons ''
Dungeon Master's Guide (First Edition) and the original Manual of the Planes. When Advanced Dungeons & Dragons
2nd edition was published, a decision was made not to include angelic or demonic creatures, and so the cosmology was largely ignored. However, fan demand for a 2nd Edition Manual of the Planes'' was strong enough to justify its expansion into a full-fledged
campaign setting, and so in 1994 Planescape was released.
David "Zeb" Cook developed Planescape when he was assigned to create "a complete campaign world (not just a place to visit), survivable by low-level characters, as compatible with the old
Manual of the Planes as possible, filled with a feeling of vastness without overwhelming the referee, distinct from all other TSR campaigns, free of the words 'demon' and 'devil' and explainable to Marketing in 25 words or less". For inspiration, Cook listened to
Pere Ubu,
Philip Glass and
Alexander Nevsky, read
The Dictionary of the Khazars, ''
Einstein's Dreams, and The Narrow Road to the Deep North, and for fun at "Bad Movie Nights", watched such films as Naked Lunch and Wolf Devil Woman''. The setting also had a small number of novels.
Later editions Upon the release of 3rd Edition, Planescape, along with most other settings, were discontinued, although fan sites such as planewalker.com were allowed to continue to use the material and update it to the new edition. The 3rd Edition
Manual of the Planes (2001), the 3.5 Edition ''
Dungeon Master's Guide (2003), and the Planar Handbook'' (2004) also used the general layout of the planes and some of the details from the setting, including Sigil, but these are not part of the Planescape line. Sigil is described in the 4th edition
Manual of the Planes (2008) and expanded upon in ''Dungeon Master's Guide 2
(2009). Shannon Appelcline, author of Designers & Dragons'', commented that while Sigil "had been largely ignored during the 3e era", it "was faring better in 4e, despite the large-scale restructuring of D&D's cosmology" due to small inclusions in the ''Dungeon Master's Guide
(2008) and Manual of the Planes''. Appelcline highlighted that it was the 4th Edition ''Dungeon Master's Guide 2'' which "saw the return of the fan-favorite setting of Sigil" which "was laid out as a full paragon-level setting. There's not much new here for old-time fans of
Planescape, but there was one
big change as a result of
Faction War (1998). The factions that caused much of the conflict in
Planescape are now gone. [...] The ''Dungeon Master's Guide 2'' also contains 'A Conspiracy of Doors', the first Sigil adventure to see print in many years". There is also some information on Sigil in the 5th Edition ''Dungeon Master's Guide
(2014). In July 2022, Unearthed Arcana: Wonders of the Multiverse
was released as part of the Unearthed Arcana public playtest series for the 5th Edition. Both Polygon and ComicBook.com highlighted that the new character race – the Glitchling – and other references to the Planescape setting might indicate a reboot of the setting for 5th Edition. Charlie Hall, for Polygon'', commented that "this wouldn't be the first time that Wizards used playtest materials to tease a reboot of a classic setting". ==Reception==
