A "wyrm" is a term often used in mythology and folklore to describe a type of dragon or serpent. Traditionally, wyrms are depicted as long, snake-like creatures without wings, and they are often associated with water or earth. In various cultures, they can symbolize chaos or destruction, but they may also represent wisdom and ancient knowledge. In literature, wyrms appear in many stories, including Beowulf, where the hero battles a dragon-like creature. The concept of wyrms has influenced modern fantasy genres, leading to the portrayal of similar creatures in games and books, such as Dungeons & Dragons and The Hobbit.
