Research is not hard. I wanted to make a small fantasy setting for a project I am doing for fun, and I wanted to have the elves in my setting be based on Otto-Turk cultures and mythology.
Instead of using a machine that only knows how to string sentences together in a way that imitates the most commonly used sentence structures. (which is why they are called LLM's, Language Learning Models.) I just spoke to two of mt friends who were born and raised in Turkey a couple questions then used Wikipedia searches for the rest.
It took two afternoons, where I did an 8 hours shift in the morning, to make a faction of elves who have a culture and feel that is VERY Turkish/Mongolian,but wasn't a copy and paste job. If you cannot just look up how a bird's immune system works. That is on you.
