My first NaNoWriMo isn't going well exactly, but my story is absolutely progressing.
One of the most encouraging developments has been the fleshing-out of my villains. When I started I had some idea of what they wanted, but very little of the why, and even less of what they looked like. As my eventual plan is probably to draw this story up into a graphic novel, the visual vagueness of these two very important characters was a serious problem.
Interestingly, I found that as I gave these characters a history and a setting their appearance developed quite naturally. (This is a bit of an inversion for me- historically I'd come up with a cool looking character, and then have to make up reasons that they looked that way. Which maybe had something to do with why, historically, my plots were underdeveloped.)
Her name (at least until I decide to change it) is Ethelinda. He is Ofure. This is a picture of them in younger, happier days. At this point they are the heroes of their own story, not the villains in someone else's.
