As part of my final edits for "C is for Change" (yeah, I let the title slip the other day in social networking, ah well *grin*), I needed an easy-to-follow means of revisiting the story's magic system to make certain it was consistent throughout. So I flow charted it. I probably should have created something like this closer to the beginning of the drafting process, but I did find it helpful in edits, and I'll likely create a similar flow chart for future storytelling processes of this kind.
There aren't any spoilers in the chart, so I thought I'd share it with you in the hope you might find it helpful to your own writing. I used an online service called Gliffy and found it helpful, but I'll likely look for a Linux or MacOS solution going forward.
