Floating cities and islands in fiction are imaginary places that exist only in books, movies, and other stories. These places are usually made up, meaning they don't really exist in real life! Some examples of floating cities and islands in fiction are the city of airships in the movie Steamboy, the city of Coruscant in the Star Wars universe, and the flying city of Laputa in the anime movie Castle in the Sky. These cities and islands often appear in fantasy stories and are often used as a way to explore ideas about different ways of life, as well as adding a unique element to these stories.
