I want to clarify that, in regards to Asian mythology, I was more referring to animism as “the attribution of a soul to plants, inanimate objects, and natural phenomena”. As in, trees have souls which appear as nymphs, rivers are the physical bodies of dragons, and old pots and stuff eventually develop a soul after a century or so. Particularly, it is the anthropomorphism of beings and objects which don’t normally have that quality.
This is not something we see in the Astlan world, as inanimate or non-sentient creatures aren’t shown to have any consciousness greater than what is accepted by science.
Also, if you want to add a more Asian influence, I would suggest starting to diversify your demons. Get more oni, youkai, all of those ogres and rakshasas.
Though, now that I think about it, what would happen if someone did the demon summoning ritual on the soul of an animal or plant? Maybe there’s some demonic flaura and fauna that you’re overlooking! (Though, there are the hellhounds. If there are magical beasts like that, why aren’t there huge packs of them living wild? I mean, they would still have their biological imperative to breed, and aren’t hunted, and very hard to kill, so…)
