The pet dragon!
My name is Lucas, knight of the realm Enchanted. Recently a dragon attacking the castle and kidnapped the princess Luaisy. I am instructed to go save her. The problem is that the cave is not three paces from here. So, I ride my black stallion and went to the sacred mountain. It took me three days to get there. Once in front of the cave, I hear laughter. A sweet and beautiful laughter I recognize. I enter with caution and after a minute's walk, I see the princess petting the dragon's head. The dragon rises automatically and growl. By the time I was going to attack, the princess stop me and tells me that in made, he is gentle as a lamb and that he sought the company of a pure person. After that, the dragon becomes the companion of the princess.
