Fictional currency refers to money that exists only within a fictional universe, such as books, movies, or video games. It is created by authors or game developers to enhance storytelling and world-building. Examples include Galleons from the Harry Potter series and Gold from the World of Warcraft game. These currencies often have unique values and uses that reflect the culture and economy of their respective worlds. They can be used for trade, purchasing items, or as a plot device. Fictional currencies help immerse audiences in the narrative and provide a sense of realism to the fictional settings.
