Vadleany

Vadleany comes from Eastern European (Hungarian?) folklore. She is a forest sprite -- her name means "Forest Girl" (literal translation: wild girl) -- who seduces wanderers and steals their strength. She is usually naked and has extremely long hair.

The vadleany appear in the fictional world of El Arcana [http://ee.domaindlx.com/elarcana/ref/guidebook/monsters.html#vadleany] as woodland nymphets who lure men into the woods and then drain their energy. It also appears to be a not-infrequent pseudonym for teenage girls from Russia or Scandinavia.
