To me it looks inspired by sherpas and Nepal. Nepal already has a living god similar to this. Her feet cannot touch the floor and she can only the attended to by her attendants. People come to her to be healed and receive blessings. But the outfits and the place seem to be up in the mountains so either sherpas or Tibetan. Even the outfits look more Tibetan.
Sherpas are considered a seperate group of people to tibetans or nepalis tho they are from Tibetan decent. That was a long ass time ago tho so they have a separate cultural identify. They are nomadic and sometimes polygamous. Most are Buddhist tho I guess not every Sherpa needs to be Buddhist. They live across the mountain ranges so they are not specifically from any region like “Tibet” or “Nepal” tho I think most live in Nepal now.

Hanuman and Asura!?!?!?
