An elf is a mythical creature often found in folklore and fantasy literature. Traditionally depicted as small, magical beings with pointed ears, elves are known for their agility and connection to nature. They are commonly associated with Christmas as Santa Claus's helpers, making toys and spreading joy. In various cultures, elves can have different characteristics. In Norse mythology, they are considered powerful beings linked to fertility and the earth. In modern fantasy, such as in J.R.R. Tolkien's works, elves are portrayed as wise and immortal, possessing advanced skills in magic and archery.
