I’m not sure how to place mine in the poll.In discussions of D&D, I often see arguments based on the assumption of unambiguously real, universally acknowledged gods. While this framework certainly describes many settings, I don't think it's fair to take as given in a game played in as many different settings as D&D. I also think the degree to which the official books emphasize this assumption is overstated. The DMG presents "Gods oversee the world" as a core assumption, but it does so in a section specifically about how DMs might choose to modify those core assumptions. And while the PHB and MM make plenty of references to gods, few of them have mechanical weight, and most are presented in a form that could be regarded as in-universe belief just as easily as established canon.
Personally, I have a strong preference for worlds where the existence and nature of gods is left deliberately ambiguous. A setting where the players and characters definitively know the answer to religious questions, in my view, takes away many of the dynamics that are key to making religion feel like religion. Rather than contemplating faith in the face of uncertainty, characters are simply choosing how to interact with powerful characters.
I recognize, though, that this view isn't universal, and I'm curious as to others' preferences. How do you prefer that D&D settings handle these elements of in-world religions?
One of the distinctions I make is the ease and clarity of communication. Speaking with a djinn or fae might be confusing or tricky or even dangerous. "Can I have five minutes of your time?" coming from a fae requires a careful answer. Even so, a direct communication is possible. Speaking with a deity may not be comprehensible and could even be mentally or physically dangerous. A deity may also not be able to directly act unilaterally. Whereas a djinn could lose their temper and take out a platoon or village that was in the wrong place, a deity may only be able to inflict damage on the same target under specific circumstances.The line between Djinn, Fey Noble, Celestial/Demon and God is quite plausible arbitrary, but it just amounts to "how many people can they squish with a single gesture?" That is right up there with "is there a material difference between warlocks & clerics?"
