I tried once, while writing another story, and I gave up mainly because I had too many characters in the story, itself, I think. I just didn't have enough "write" to go around for all of them.
I think I just got less and less organized as time's gone past. Only thing I have for Hollowmark as far as that goes is a paragraph in my notebook, and I might not have even stuck to it....
Yeah, been there done that, still wear the tee shirt for that too...One of my "visionarys" changed description three times throughout one of the stories, and the only way I could justify it was to make it so she appeared differently to different people.
