Deadly skies (Astrid X Male!Reader)

Your a young adult, who can't remember anything about yourself. Somehow your an expert dragon trainer, and are really good at defending yourself. Theres something strange about you though...
(This is my first X reader story, in fact its my first story. I wanted to do it after reading "Hidden fury". I decided to base the start on that premise, full credit to @DragonessFire)
