In European folklore, elves serve various functions in mythology, often depicted as supernatural beings associated with nature, magic, and the unseen world. They can represent both benefactors and tricksters, influencing human lives positively or negatively. Elves are typically linked to the realms of forests and the wild, emphasizing the connection between humanity and nature. Their actions often reflect broader themes of balance, harmony, and the consequences of human actions, serving as metaphors for the relationship between people and the environment in cultural folklore.
