Crystal was the mother of Birchbark and Rock, she got her name from her almost translucent white hair. She died a few decades ago when she was gored by a bristle-boar. Crystal had a very cheerful personality and was always up for a game or a hunt.
I am very pleased with this picture, she looks exactly like I had imagined her. I really like her outfit too. The only thing that went completely wrong was her hands, they turned out way too small, so I chickened out and cropped the picture above them so you can't see them.
