The spirit friend, a guardian spirit identical with the Irish Liannan-Shee. A familiar or household spirit who was implacable in resentment but unchanging in friendship. One of the two familiar spirits known in the Isle of Man, the other being the Dooinney-Oie. The Lhiannan-Shee attached itself to a particular person and could bring either great fortune or great ruin depending on how the relationship was maintained.
