Write the story of the "Invisible Dragon", a dragon who terrorized a village, demanding they sent him a new virgin every month. Describe how many young men from the village tried to defeat the dragon and never returned. Describe how it is later revealed that the dragon never existed,  while both the young men and the virgins were alive and living a new happy life in the forest. The "Invisible Dragon" was nothing more than a scheme created by the young people of the village, to escape the village and live free from the bigotry of the villagers.
