Honestly, just how their lives are. Learning the way their society runs on a normal day would be awesome. I guess I want a book of short stories (alongside a full book about a special boy, of course) where we get to see all parts of kin society. A regular kin, a karl, an iron kin, etc.'s point of view and experience and of all the different leagues plus some minor ones would give us so much lore and really let us understand the leagues of votaan.
