[@The Angry Goat] Mine tend not to change quite that much...but I do find their concepts grown and expand as they see use in different places.  I think the most dramatic changes come when I play them at different ages, but this time around Amune, my Seer girl, is having serious trouble whereas in all other settings she's managed to find training before reaching adulthood.  Not knowing how to control her magic and having it affect her to the point where she's not sure what is and isn't real has seriously damaged her confidence, and it's kinda fun.
