Dwarfs are mythical creatures who appear in folklore, fairy tales, and fantasy literature. In stories, dwarfs are often depicted as short, stocky, and bearded individuals who live in underground communities. Some famous examples of dwarfs include the seven dwarfs in the fairy tale "Snow White and the Seven Dwarfs" and Gimli, the dwarf warrior in J.R.R. Tolkien's "The Lord of the Rings."
