This is a HTTYD AU about Hiccup finding a new Dragon called the 'Night Shader'. It felt random and mysterious to him. The other dragon riders agreed that they would look for other new Species. The Night Shader had a rider who looked like a female Viking from Berk. The Viking's name was Teriba Haddock who was Hiccup's sister, but Hiccup didn't know her until his father told him.
