In a novel written from the POV of several characters (5 "main" characters). I've written other prologues and mid book breaks from other perspectives that could also be made into chapters instead. HOWEVER these are secondary characters or "the antagonist(s)" and they may only make up 1-2 chapters *clarification* [per "other character"] in the whole novel. At what point do these characters no longer have the depth to provide their own chapter. Is that necessarily a disqualifier for making them into a chapter? I feel they can offer perspective or knowledge to the story the other chracters couldn't. At what point is it simply too confusing to read from too many different voices. (Is there such a magical #?) I realize I am providing no story-line context what so ever, so try to stick with your experiences with other POV authors and how many charcters they tumble around with? Do they follow just the select few protagnaists? Do they follow the antagonist at all? How about the supporting cast? Do their voices get chapters?
