The most miserable dragon in history, Viserion, was beaten down while flying, and died alive while bleeding out all the dragon's blood. He was also whipped into a corpse by the Night King and trained into a mount to deal with his brothers and sisters. The key is that this is not the most terrifying thing. He was whipped twice to follow the Night King. They were wiped out together, and in the end not even a scum was left... It was already miserable enough to be the most miserable dragon in history, but there was something even worse: I possessed the dragon body before Viserion died. I started running for my life in order not to be whipped, I started to become stronger in order to survive, and I started to walk all over the world for the sake of the dragon clan.
