Okay, lemme add my two cents to this.
Firstly Kaveh: We decided to go something that related to him because I am Kurd and Kaveh (or Kawa, as we say in Kurdish) the blacksmith is the mythos of Kurds; this story is the start of Newroz (Nevroz, Nawroz, Nevruz, etc.) which is Persian Spring Celebration and also Kurdish New Year. I have heard many differences on how the story goes from different Persian ethnicities, cultures and communities.
Secondly, Djinns: Djinns are, by far, the most used horror material in Turkish horror media. I remember when I was really little, my cousins and sisters locked themselves up in a room, watching Dabbe (could be known as D@bbe) and all I, as a 7 yo or so, could hear was their screams. They're so scary to people that instead of saying "cin" (djinn in Turkish), we refer to them as "üç harfli" (three lettered) in order to not accidentally fall them to a place.
Yet in the religious aspect, they're not at all what they're made out to be. In Islam, Djinns are just like humans; instead of dirt, they were made by fire. They, just like humans, have free will which is why they can be good or bad. Some djinns are also Muslims but some aren't. We aren't supposed to be in contact with each other since it is considered makruh (something that isn't a sin but still is not permitted). Therefore, it is looked down upon to have a relationship with a Djinn. Yes, it is believed that you can have a romantic/sexual relationship with the djinns but just because you can, doesn't mean you should. Djinns are also believed to have the power to possess humans, you'll see the cases as such in Turkish horror movies a lot.
Yes, djinns do have a preference to not be around humans; so they choose empty, abandoned places. They prefer the dark, corners, silent places. I remember when it was late at night where my sister, my father and I were returning home from work and my father, who was driving the car, out of nowhere said "did you guys see the djinn?" and when we were confused, he pointed to the place we just passed and said "yeah, see, there's a djinn there." My father never makes jokes relating to religious stuff, so we both were confused and horrified at the thought. We just didn't pursue it more than that. The place he pointed to is usually empty since it's a patch of grass in the side of a highroad, so if he didn't imagine things, there is a high likeliness of one being there.
I hate the fact that whenever Djinns are mentioned in Western media, it is either a genie or a trickster. Or even worse, I'm looking at you, Marvel Cinematic Universe. I can go on and on about how much I hated the way they used Djinns and created a thing called "Nour Energy" (?) but this isn't the place for it. I wanted to focus on more religiously accurate and culturally relevant version of djinns. I'm glad we made that.
