I have my own universe as well. Like you it all started to develop mid-elementary school, and also like you I was good at doing the exposition then write the stories, but a teacher helped me find a way to actually write it all down in story form. I lost the method after I was done with the five books so I haven't been able to write a lot more in my universe. Most of my characters I would say, seem like NT’s, except for my main characters, they are as I like to say like me. They are either alien but don't know it or half alien but don’t know it. Stuff like that.Hmm, how to even describe it. I think I had a variety at first, but by mid-elementary school I had a universe that's never really stopped developing since then. I guess it's sort of a mix between a sci-fi and fantasy world, full of aliens and somewhat scientific but also with plenty of fantasy elements. By this point it has multiple generations and history and social structure and culture and even main characters who could be considered neurodiverse, although none of them are human so not in the same way we are. I've written a little about it but haven't managed to turn it into book form. I seem to have two main problems; first, by the time I tried to write it down it had become so complex that it was hard to figure out where to start, and second, I'm much better at writing exposition than narrative. So I've written plenty about it, but only little snippets of stories. I'm working on improving my narrative skills, though. I wish I could just transfer everything in my head to paper. I'm also rather self-conscious about it, though, because I'm used to not being able to talk about things like that to anyone because my family isn't interested in that kind of thing and neither were any friends I've had. What were your worlds like?
