So, when I'm working out plot, I tend to snowflake (start with one or two simple points and then expand/expound until plot happens, rinse and repeat until you have a book). The problem I'm having is that I started with a fairly straightforward outline... and it's not straightforward anymore. The more I looked at it, the more backstory and world building and plot-relevant history I found. So now what I thought was one book is more like material enough for at least three... and I'm only halfway through the overarching story. I'm really tempted to just say "forget it" but the stuff I'm finding is all stuff that's actually kinda necessary to understand the plot and most of the characters. It's too much information to be able to sneak it in here and there without it being awkward and it's going to really interrupt the flow of my story if I have to pull a Tolkien and spend a whole chapter introducing every new place, character, object, and idea as it comes along. Basically, I have an absolutely unholy amount of information to work with and I really need a way to categorize plot points/organize it into a more coherent structure. Does anyone know of any ideas/layouts/programs that might be helpful?
