World creation refers to the process of developing a fictional universe, often seen in literature, film, and video games. This involves establishing the setting, including its geography, history, cultures, and rules. Creators may draw inspiration from real-world elements or invent entirely new concepts to build their worlds. In many cases, world creation includes the development of unique characters and societies that inhabit the universe. This can involve crafting languages, religions, and social structures, allowing for rich storytelling. Notable examples of world creation can be found in works like J.R.R. Tolkien's Middle-earth and George R.R. Martin's Westeros.
