World building is the creative process of constructing an imaginary universe, often used in literature, film, and games. It involves designing the setting, including its geography, culture, history, and rules. For example, a fantasy world might feature magical creatures like dragons and unique locations such as enchanted forests or ancient castles. This process helps to create a rich backdrop for stories, allowing characters to interact with their environment in meaningful ways. A well-built world can enhance the narrative, making it more immersive for the audience. Think of iconic worlds like Middle-earth from The Lord of the Rings or Wakanda from Black Panther.
