A Fictional World is a constructed universe that serves as the backdrop for stories, often featuring unique rules, cultures, and histories. These worlds can range from magical realms like Middle-earth in The Lord of the Rings to futuristic societies in Dune. Writers create these settings to immerse readers in imaginative experiences, allowing them to explore themes and ideas that may not exist in the real world. The depth of a fictional world can enhance storytelling, making it a vital element in genres such as Fantasy and Science Fiction.
