Robin Goodfellow, more commonly known as "Puck," is a spirit that haunts the British Isles. Depending on the myth, he is a fairy or goblin or sometimes a demon. Puck's origins are shrouded in the mists that once hung in the rich British forests, but we do have some clues as to where he came from. Whereas Jack Frost's origins are relatively recent and easy to follow and were not Norse (despite urban legend saying so), Robin Goodfellow seems to come from truly ancient origins and does seem to have actual Norse connections.
