If you’re meaning spend more time with that behind the scenes, on my end, no worries, I already did. If you mean stop and explain it all to the reader, then; A. I’m not just gonna stop & exposition dump it all. Their backstories & whatnot will be expanded when it’s appropriate. For now, you have the basica of each character & where they came from. B. It’s a sequel, so a lot of the world & magic system is already built. Though, that’s also best introduced over time, not dumped at the beginning. I suppose I should specify, I have most of this plot hammered out. I only need a chapter or so to help keep the beginning from feeling rushed.
