We already know about 1 character coming to us in Natlan. The chibi Iansan.
I think people have looked her up by now so we know Iansan is based on a godlike being called an orisha in the religion Yoruba which is from West Africa. Her full name is Oya Iansan-an.
Not quite as chibi is she?
But I think for our purposes Iansan actually goes further than that. A long while back I made a theory on what the story might be in Natlan. The title of the chapter is Incandescent Ode of Resurrection so resurrection is going to be a major theme. Since my theory on Murata is that she's the resurrected General Musatas aka the Fire Rat of the Southern Volcanoes I think it will be about her trying to bring back the other yaksha.
How does Iansan help with that theory? She is the orisha of death and rebirth for one. Based on her mythology she understands and can even control the mysteries of death. Probably going to be important to a story about resurrection.
Side Note: Also Iansan means mother of nine. I found that funny imagining 9 kids popping out of that chibi character lol 
But there might be a Yoruba basis for Murata too. Iansan's partner is Shango. Shango is a mythical ruler of the Yoruba people, an orisha of dominance, aggression and war and is associated with the color red. Is there any better fit for a Pyro Yaksha who was a General during the Archon War?
So if this ends up being the case then Shango could also hint at a few things about Natlan. For one he was said to be a leader of the Yoruba but during his reign the empire fell into civil war. I suggested that the Fatui we'll face over there is Sandrone who is a manipulative person that will push Murata to her goal of resurrecting the other yaksha. That might not sit well with her people so we could be seeing the civil war play out in the Archon Quest.
The next this is pretty cool but I don't know if MiHoYo would go for it. Shango is also known for his labrys or dual headed axe. We don't have axes in Genshin but I've previously made a suggestion for it because it could make future gameplay more interesting. And to their credit at least when it comes to Catalyst characters they've played around with the fighting styles. Heizou is set to become our first brawler.
Finally I've stated that the design of the Muratans in the manhua better resembles Native Americans than West Africans. And similarly Yoruba was imported to the New World (via the obvious method 
) but because it was it makes sense that Murata might not be a local. I mean the name itself would be Japanese without any way around it and most theories claim she will be based on Murata Himeko of Honkai who is 100% Japanese. Meanwhile if my yaksha theory continues to hold true then she's essentially Chinese or Indian just by what she is. No matter what though there's no Muratas or Musatas native to South America lol The fact that Yoruba is also not native though makes this not an issue.
And that adds to another factor in Natlan's Archon Quest. Last time I suggested that with the information we have so far Murata might take some inspiration from Aztec Tezcatlipoca. Just like we hear in Travail this god likes to challenge warriors to duels where the loser will be sacrificed. The winner will burn bright while the loser is turned to ash.
So going back to Iansan she is also said to be an unbeatable warrior. If she's set to be a major player in the story it could be that she'll take over for Murata as a human allogene leader and carry Natlan into the Human Age. Since Iansan and Shango were married though they may even start out like Yae and Ei only in reverse where Iansan was a loyal warrior under Murata but as she becomes deeply influenced by Sandrone Iansan has no choice but to challenge her and burn bright as the new human leader of the region.

Commentaries on Genshin Impact and MiHoYo
PS: A week ago I talked about something cool I found out about Kusanali and how it related to Achaemenid Persia which I had theorized was where Sumeru is actually inspired. But alongside that discovery was something I knew would make certain people mad. And wow did it lol
Thankfully it also allowed our Persian gamers a space to talk about the reality of their region and people. 
And I wrapped up that topic by saying man Natlan can't come soon enough. If all this is right well there's hardly any pale people in West Africa and South America. And every Muratan we've seen so far has been dark so that should solve any lingering issues about that. (it won't but we can still hope)
