The Lost (The Shining Man)

A Boggart, knwon among the Fair Folk as the Lost was caught by the Fairy Finder and cast in a deep hole. A tree was planted on this hole, its roots wrapping around the Boggart, who hibernated.

The tree's roots absorved some of the Boggart's magic, and formed a connection with Sammy Holland, who used to play around the tree when she was young. (PROSE: The Shining Man)
