Oc information

What if Hiccup had an older twin sister and she was the next in line for chief? Her name is Thyra Haddock. Her dragon is a Deadly Nadder and her dragon name is Shadowfang. Snotlout has been trying to get Thyra's attention since the movie. Snotlout has had a crush on her for years and didn't know that she has a crush on him too.
