Fictional deities are gods and goddesses created within various forms of storytelling, such as literature, movies, and video games. These characters often embody specific traits, powers, or domains, influencing the narratives in which they appear. Examples include Zeus from Greek mythology and Gandalf from J.R.R. Tolkien's Middle-earth. These deities can serve various purposes, such as guiding characters, representing moral lessons, or adding depth to the world-building of a story. They often reflect the values and beliefs of the cultures that create them, allowing audiences to explore complex themes through their interactions and conflicts.
