After spending a year plotting a story, I've decided I could easily write about my characters adventures over a series of books. Each story will be unique but I want to build a 'bigger' plot if you get my meaning. My problem is this - part of the bigger plot involves characters that are very minor in the first story. I was considering just leaving them out of the first one and writing them in when appropriate but I felt it added to one of my main characters story just by having them in the background. anyone any opinions on this?
