Thread starter: Given the nature of dreams ( archive.4plebs.org
Discuss Planescape and the Great Wheel here, whether the original AD&D 2e version, the 3.X version, the 4e version (traces of the Great Wheel exist in 4e, down to the baernaloths, the yugoloths, the Heart of Darkness, Maeldur et Kavurik, Tenebrous, Pelion, and the Last Word all being canon as of Dragon #417), the 5e version, or your own original blend.
I am exceedingly well-lanned on planar canon under a holistic blend of 2e, 3.X, and sporadically even 4e lore. If you have any questions at all about the setting's lore, feel free to ask, and I will give you direct quotes and citations from as many primary sources as I can, unlike afroakuma. I will note when something is open to GM interpretation, and explicitly note whenever I give merely my own personal interpretation.
If you would like to ask anything under the context of a single edition and nothing more, please mention such.
