What starts off as a minor idea to nudge the plot in a specific direction, ends up compelling enough to expand into more. I don't want to get into details, it'll ruin the fun of the book. What I am getting at is that this book may end up longer than I had originally planned. It may also turn into another book. As this set/trilogy was supposed to be about the battle against the Lords and foreshadowing the next set of books, I can see ths easily being much longer than three books. The question that keeps poking me in the side is: How far do I go?
How many books are too much for one major point? Is it determined by if the subplots remain interesting and on point, or is there simply a time where no matter what you do, no matter how good the subplots are, there is just too much time spent on a major piece of the puzzle? So far, I don't have an answer to that.
