Fictional ethnicities are cultural groups created in literature, film, and other media that do not exist in the real world. These ethnicities often have unique languages, traditions, and histories, allowing creators to explore themes of identity, conflict, and community. Examples can be found in works like J.R.R. Tolkien's Middle-earth or George R.R. Martin's Westeros. These invented groups can serve various purposes, such as enriching a story's world-building or providing commentary on real-world issues. By crafting distinct cultures, authors can engage audiences in discussions about diversity, belonging, and the human experience, often reflecting or reframing societal norms.
