The term "Dökkálfar" refers to a type of elf in Norse mythology, specifically known as the "dark elves." They are often depicted as living underground or in dark places, contrasting with the Ljósálfar, or "light elves," who are associated with brightness and beauty. The Dökkálfar are believed to be skilled in magic and craftsmanship, often linked to the earth and its hidden treasures. In the Edda, an important collection of Old Norse literature, Dökkálfar are mentioned alongside other mythical beings, highlighting their role in the rich tapestry of Norse cosmology. They are sometimes associated with mischief and trickery, adding complexity to their character in folklore.
