@KTama147 to answer your question I read other books, secondly: fandoms I am in mostly, of course I also needed a bit of research to what this fandom particularly does and what it is, thirdly: I go with the flow with what my mind makes up for the book, or take inspiration from other books, for example "Cold Souls" is my book about Dream dying and becoming a ghost, I took inspiration from other stories and made a version of that for my own despite having small knowledge of the fandom or the Dream SMP, I get inspired by the way the stories are written, and how the ideas are placed there, of course it's a hard and rough process to come up with an idea for a book, but it takes time and lots of patience to make it. Hopefully you get it because this is all I can type in from what my head is saying ;-;
