In Norse cosmology, svartálfar, also called myrkálfar, are beings who dwell in Svartálfheim. Both the svartálfar and Svartálfaheimr are only attested in the Prose Edda, written in the 13th century by Snorri Sturluson. Scholars have noted that the svartálfar appear to be synonymous with the dwarfs and potentially also the dökkálfar. As dwarfs, the home of the svartálfar could possibly be another description for Niðavellir.
