Arya seems very Mary sue by the time the series arc and war is over. She is the queen of the elves, a dragon rider who's dragon is mated to saphira, as well as one of the last three living dragons, and she is extremely beautiful, intelligent, strong in magic and fighting. I think the balance with her emotions isn't enough, as she seems so calm and mysterious and ends up always the one who needs to be apologized to when people do something wrong. It seems like she needs a better backstory than "oh, my one true love and beat friend died, and my mother rejected me for seventy years. Pity me... "
I mean, this is a discussion board, so do you agree?
