Editing Planescape (section)

==Semi-Planescape books==
Whilst the sections above list everything that actually bears the Planescape marker, the city of [[Sigil]] has managed to survive in D&D better than the formal setting has. Sigil is fleshed out in detail in the [[Manual of the Planes]] for both [[Dungeons & Dragons 3rd Edition]] and [[Dungeons & Dragons 4th Edition]], with the latter being 98% a reprint of the former. The 4e version of Sigil was expanded upon in the 4e [[Dungeon Master's Guide]] 2. [[Dungeons & Dragons 5th Edition]] gives Sigil little mention except for saying that it exists and has portals.  Tasha's did expand on this, by mentioning a little more in their rules for patrons.  Likewise, a version of Planescape will be created in 2023 for 5th Edition, according to a recent reveal.  More than likely, this will explore a new version of Sigil.

These post-AD&D versions of Sigil depict a post-[[Faction War]] take on the city, with the Factions having faded into the woodwork and a rising new power structure made up of guilds and gangs lacking the philosophical unifying power of the original Sigil.

Additionally, even before that, TSR put out at least two planes-focused splatbooks that weren't branded as part of the Planescape line: ''A Guide to Hell'' and ''[[Warriors of Heaven]]''. The latter is particularly egregious in its exemption, as it provides expanded information for all of the major [[celestial]]s of the [[Upper Planes]], including full-fledged PC stats, and has the long-missing "random generation tables'' for [[Aasimar]].
