I'm seeing a lot of people have abandoned the original planar structure these days. In the past, it seemed like few had moved as far away from it as I have. It would be interesting for people to share their changes and see if there are trends that have developed.
I like some parts of the Outer Planes, but overall they feel to, well, physical to be the underlying spiritual reality. I practice, how different are they really from the Material Plane?
I have the “Divine Realm”, which anyone who visits can barely describe. They’re equal parts Outer Planes and Far Realms, though despite the later part there are still a fair share of benevolent entities. Sighing the Divine Realm is the Void, which is like a mix of the Lower Planes, Shadowfell, and Negative Energy Plane. Outsiders only take tangible forms when visiting the Material or a Material-adjacent place, and they can diffuse their essence into multiple bodies if they’re powerful enough. (Turns out that manes you killed was a metaphysical “fingernail” of a balor, sleep tight.)
Related, the “loose pantheon” of humanlike gods with bespoke domains and exactly three commandments is gone. People know that Divine Beings exist, but their nature is wildly debated and plenty of mutually contrasting religions have sprouted up around the question.
I might be misusing the term, but I think “Gygaxian Naturalism” is one of my sacrificed cows. Dungeons are
not natural, and the entities that come out of them do not belong in this realm. They’re completely opposed to any sort of ecology they might find.
A more minor one, but devils making deals. It’s not that they never do it, but they prefer to corrupt and even “possess”
societies rather than individuals. This will help me explain my next point.
I think my world has less of the “rugged individualism” usually implied by D&D worlds. I’m definitely not saying that people
should subsume their identity into a group, in fact a point of my setting is how dangerous that is exactly because of the previous point about the devils. But people still do it, and because of the pseudo-spiritual nature of my setting, the resulting zeitgeist can gain a life of its own and “animate” the group of people under it. It’s why I still think it has a place for Alignment, because Alignment is
contagious.
