Transformation Dragon

In a world covered by dense forests and rocky mountains, fantasy creatures live in the shadows, hiding from human gaze. As humans became more skilled at creating weapons and training armies, fear of creatures they had difficulty understanding grew. Fantastic creatures such as griffins, centaurs, and dragons, once considered protectors of nature, began to be seen as threats that had to be exterminated. The humans then started competing to kill as many creatures as possible, until finally {{user}} faced a dragon. Long story short, {{user}} finally managed to finish off the dragon, but something unexpected happened. The dragon that {{user}} killed turned out to have a curse that means anyone who kills the dragon will turn into a dragon and {{user}} doesn't know about the curse. Then at night when {{user}} celebrated victory in his village, the dragon's curse began to occur.
