Ok, Black Annis is part of Leicestershire Folklore and is from the Dane Hills area of Leicester (now built upon). She is said to be a blue faced Hag/Crone or Witch that had large Claws and also had a taste for Human flesh (especially Children!?) and that she used to go round the Glens of the Leicestershire countryside and look for unsuspecting Children. She also carved out a Cave for herself to live with her Claws.
Does anyone have there own take on this?
