Book of Fables Entry
''Reputed to be fashioned by a Byzantine clan in an attempt to ward off a coven of witches, the Ring of Dispel (or Dispelling Ring, or Magic-Cancelling Ring) eventually was given to Lancelot by the Lady of the Lake. Recovered by the Business Office after the emigration to New Amsterdam, it was assigned to Greenleaf for caretaking.''
