Yeah, this is off the bumper of my process. I start with character and situations long before I start a world to put it all in, well except for my main series. Which is pretty much a pile of throbbing, living notes, but this is a good start. I mean Jim Butcher took Pokemon and The Lost Roman Legion to make his Codex Alera series, which was on a dare. So just jump in, go nuts, and write what you love. I got some critters in my world that sound suspiciously like Spren on paper, but they're entities of an entirely different sort, acting more like Mini-cons and tape-bots from Transformers and the AI from Red vs Blue, becuase those my two favorite shows of all time. So if it`s kinda Cosmere, let it be kinda Cosmere. I've gotten over the fear of making worlds by just letting it sound like one author until I find a few other things to merge it with.
