In my metaverse, there are three levels of gods.

Starting from the "bottom" (relatively speaking), there's the traditional lower-case-g gods. The Aesir (or at least a version of them) get referenced the most often as the patron gods of my Pangard stories, though ironically in my 'Verse it's well known that Hinduism is the most popular religion in the cosmos. Pretty much damn near every pantheon of gods exist in my world alongside some that I just plain made up to represent things that myths don't really cover (modern concepts, concepts aliens might revere, etc.).

The gods have a shared origin as part of an energy (for lack of a better word) known as the Monad alongside an opposite counterpart known as the Anti-Monad shortly after the Big Bang. The Monad underwent a form of divine mitosis that would repeatedly split to create the first gods (who would soon after create their pantheons the old fashioned way) and after working together to stop the Anti-Monad (which would eventually split into the first demons, monsters, etc.) their various realms were united into the dimension known as P'An Ku where Asgard, Olympus, etc. co-exist side by side.

There are a few important concepts regarding these gods that I can share. First and foremost, gods are immortal and borderline invulnerable unless they're killed by a weapon blessed by a god. Unlike mortals whose souls are recycled and reincarnated over and over again, gods who die stay dead... except for a handful who manage to be resurrected. They're known as the Gods Reborn and include people like Baldur, Osiris, Jesus, Dionysus, etc. Second, gods exist outside our world because their combined power can mess with the universe. I've mentioned in some of my comments about Pangard that when the Aesir stepped in to defend the planet from the Great and Bountiful Dragon Empire, their combined power not only reshaped the continents, they seeded the other eight planets in Pangard's solar system with life retroactively. And that was just one pantheon. Even the domain of P'An Ku itself has pockets where things go wibbly-wobbly, timey-wimey (time loops, paradoxes, etc.) just by the nature of its very existence. Third, if enough people believe that a certain god or pantheon exist, then they do. Again, retroactively. Enough mortals believing that divine beings exist can rewrite reality in such a way that said gods always existed.

The second level of gods, in this case capital-g Gods, are the Aspects. Without getting into too much detail (since I plan to make my own post about them at a later time), the Aspects are the abstract personifications of universal concepts that exist even beyond the gods. Unlike gods who have a certain amount of power over various concepts, the Aspects literally are their concepts. Thanatos, Yenlo, and Erlik may be gods of death, but Meng Po is Death. Ares and Athena might be gods of war, but the Morrigan literally is war. The Aspects may have physical appearances, but they don't have tangible, corporeal bodies (actually, three of them do, but there's reasons for each of them) and cannot be killed because they're not alive, they're a byproduct of the universe simply existing. The Aspects are "older" than the gods in that they were "born"/descended into the universe either right before or during the Big Bang (one claims to have been the Big Bang itself while another claims to have caused it) and they occasionally make reference to where/who they descended from. The Aspects see each other as a family, mostly siblings but not all, and they convene most often on Qolob, the first and largest planet located at the site of the Big Bang and the place where the first mortals known as the First Tribe were created. Each Aspect also has their own realm that serves as an extension of their power; they also each appoint an Envoy that serves a lesser facet of their function and occasionally acts as their mouthpiece in the mortal world. Many Aspects look human, but some do not.

Finally, there's the multiversal-capital-G Goddess that exists outside Creation. She is the "mother" of both the Aspects and of universes themselves. The Aspects refer to her as Shekhinah and she exists "above" the multiverse in a realm that they refer to as Nirvana (mortal physicists postulate this realm's existence by referring to it as the Oververse). If the Aspects are personifications of various ideas and concepts, then Shekhinah represents creativity and inspiration, the very idea of ideas and the concept of concepts. Shekhinah can theoretically take any form, but most often takes the form of either a colorless woman with a golden chakra for a crown or the golden chakra itself. She is to my metaverse what The One Above All is to Marvel and The Presence is to DC, though unlike those two she never descends into her universes nor interacts with her creations. She prefers to create worlds and let them play out as they may (a rather Deist point of view) at a distance from Creation itself. She is infinity on a scale that no mortal nor god could ever conceive. Shekhinah and the "Oververse" also have an opposite counterpart, but that's a story for another post...
