My main character is an established one for me, Mixx the Jump Jockey who's shown up in some of my other work. Kind of an antisocial loner type, which fits with her chosen lifestyle of flying around space in a pretty small single-person craft. I think it's going to sort of be a "meets some people along the way" sort of structure, so other characters will emerge, but I'm not sure yet what they'll be like. I tend to like draw someone and then let their personality come forth out of that, I guess.
