It's alright. My mother is a professor of Balkan folklore, so I know a lot about nonhuman sentient species native to the region. I'd probably use just as many technical terms if I tried to explain powers and things like that from my territory as well. The only difference is that I've been told Serbian is much harder to pronounce than the Latin you just used.

[Apparently 'mrzsrde' needed more vowels, according to most people.]
