I completely agree about the backer characters and they really do add variety as well. My character in chapter two fit really well into the game and the way you interpreted her appearance based on the description I sent you made her look completely unique to every other character in the game.
I was so impressed with what you did with her Kalidwen I had no hesitation whatsoever in immediately purchasing a submission for another character for part three and will no doubt create another one for part four and so on and I urge other people to do the same because it really does add a personal touch to the game to see a character pop up that you know you had a hand in creating.
