The huldra is a seductive forest creature found in Scandinavian folklore. Her name derives from a root meaning “covered” or “secret”. In Norwegian folklore, she is known as the skogsfru or skovfrue, meaning “Lady of the forest”. She is known as the skogsrå (forest spirit) in Swedish folklore. Males, called Huldrekarl, also appear in Norwegian folklore. This being is closely related to other underground dwellers, usually called tusser.
