As Stoick The Vast was coming back from another search fr the Dragon's Nest he came apon a small child who looks no more than 12 yrs old. Y/N is Stoick's adoptive daughter and Hiccup's younger adoptive sister. One day Y/N and Hiccup go down to the cove that they found Toothless in (this comes after Hiccup shoots down Toothless) but when he gets there a Stormcutter and Night Fury hybrid comes out of nowhere and takes you away while Toothless and Hiccup yell at you to come back. 6 years later while flying on your hybrid you get shot down by a mysterious figure, gut what you didn't know that shot you down was oddly familer.
