Once upon a time, there were stories about big scaly creatures called dragons that people told in Europe. These dragons had a lot of different looks in different stories, but many people thought that they had large wings and could breathe fire out of their mouth. Some people believed that they would kidnap princesses and take them away to their lair, and could only be killed by brave knights with a sword. However, dragons were not real creatures, they only existed in people's imagination and in stories.
