Hiccup's never been the same ever since he killed that night fury. He feels different; weirdly different. His vision becomes a thousand times sharper, his senses become sharper and he's grown stronger than ever before. By night, he transforms to a creature of destruction but by day he is an ordinary human adjusting to his village finally respecting him. However, a dark entity lurks inside him and is determined to destroy him little by little. In order to live, Hiccup needs to control it before he harms himself or anyone. *I Do not own the characters and settings. They belong to their rightful owners.
