OK, I've adjusted her CMB and CMD as requested (can't see how I missed that, oh well), and added to the background. In basic, she didn't fit in, in Magnimar. As a child, her family visited Sandpoint once or twice a year, and on hearing about the festival, she realised she may like it better there. Mysty is searching for allies, and friends, something she hadn't found in Magnimar.
Also, fixed the formatting problems. Thanks for the feedback on that.
