"The Bonuwat people of the Mwangi Expanse worship a variant form of Gozreh, a janiform amalgam with Desna, whom they call Shimye-Magalla."
So what do y'all reckon this looks like in Mwangi depictions? It's a little confusing in that Gozreh already has two aspects, the female water aspect and male air aspect, which I could see representing in janiform fashion (definition: like the Roman god Janus, a face on either side of the head like this). But adding in Desna makes it a little more confusing, as potentially there's three faces involved.
I have a couple kind of art concepts in mind:
1. Two female faces, female body - a "water" female face with waves for hair and an "air" female face looking more like Desna. Of course it's hard to say what "looking more like Desna" means in this context since they doubtless represent Shimye-Magalla as black. A potential visual inspiration.
2. One male face, one female face - a "water" male face, swapping the usual M=air,F=water Gozreh aspects, and an "air" female face with butterfly wings or whatnot to indicate Desna. Interestingly, here's a janiform African mask with one white/female and black/male aspect, and another with some interesting writeup attached. I suspect this may have been the inspiration for S-M because as I google it looks like this is a common thing in Nigeria and related regions.
So is a body represented? Male, female, or both? (Seems like the African masks are just masks so don't answer the body question... Maybe just "never represented with a body in particular except some big straw-costumed dancer" makes sense.)
3. Don't take janiform too literally. The Bonuwat are a seafaring people and more travelled than the peoples of the interior, we could go more of a voodoo route. This brings to mind some depictions of Papa Ghede, the voodoo loa, where half of the face is a skill and half is normal. S-M could have "half" a female and "half" a male face.
And then what would religious practice be like, more traditional African (which is hard to map since they had lots of gods and it sounds - implied but not clear - like the Bonuwat are mostly about S-M) or more like voodoo or more like "generic made-up RPG religion"?
I have a character playing a Bonuwat in my Reavers on the Seas of Fate campaign so I'm trying to develop this out a bit... He was actually wandering around Riddleport trying to find a shrine or whatnot, he found one to Gozreh and it was close enough that he used it, but it got me to thinking...
