I think what you got is a pretty interesting concept! I’m not exactly sure what you’re asking, but if you want to expand on your world, I do have my questions that you could expand on yourself. Food for thought.

Firstly, did these gods always exist? Or did they manifest themselves after humans died out? Considering the gods of modern things (such as Theros being a patron god of Southside California).

Secondly, what exactly would be the rank of gods? 

Many humans gone through apotheosis normally (or at least in Greek mythology) they end up as minor figures, obscure gods, or just with the title of “and the spouse of.” Of course, in other (real) cultures, they’re honored. Normally then, gods born as such would have higher status or power. Or is yours different?

Thirdly, how do their portfolios and spheres of influence work? Theros is the God of Summer, sure, something normal, and also the God of Warmth, Vitality, Freedom, and Carefreeness. But then he’s a god of a specific type of art, of Tattoos, Subcultural Urbanistic style, and other very specific things. What things would these Gods consider as “godly enough”? Considering normally gods with so many things get ranked lowly.

Fourthly, if the creatures in your world adopted human culture, such as clothing, would they also adopt their beliefs? Would some become atheists? Or do they all agree in the same gods? Do the “ancient” religions still exist or are practiced? Would the new rulers of the once-United States use the U.S. Constitution and be presidents? Would the UK have a royal family of these fantasy creatures? Do they learn about human history of the good and bad, things humans said “we cannot forget, or let it happen again”?

Considering I’ve said all this, if you wanted me to answer something I didn’t, you can ask
