Thyra, daughter of Hiccup and Astrid, is probably the only Viking on Berk who strongly dislikes dragons. Nobody else she knows dislikes dragons, and she doesn't know why she has had this dislike when nobody else seems to have it. It isn't till one day when she finds a dragon lost in the woods, that she realizes things aren't as they seem... ... and what she thought she was, isn't who she truly is.
