Niflhel ("Misty Hel"; Nifel meaning fog) is a location in Norse mythology which appears in the eddic poems Vafþrúðnismál and Baldrs draumar, and also in Snorri Sturluson's Gylfaginning. According to Snorri Sturluson's work, Niflhel could be interpreted as the lowest level of Hel, but Niflhel and sometimes Hel are conflated with the concept of Niflheim, a term which originates with Sturluson.
