Mind Mapping, I've tried this really only once and, of course, with software. It was for the first novella I ever did (Road to Adventure in What Dreams May Come) and that scared me. With the publishing of Feral Magic, I'm ALMOST over my fears of novellas.
In any event, here's the map. Some elements (I vaguely recall), did not make it into the novella because (SURPRISE) I had too many subplots and cut one out. :)
Good luck and happy mapping to all who use this tool!
