Silver C.S. Lewis 'Lamp-post' charm. A solid silver disc with the lamp-post on one side and Narnia engraved on the reverse.
“This is the land of Narnia,' said the Faun, 'where we are now; all that lies between the lamp-post and the great castle of Cair Paravel on the eastern sea.”
― C.S. Lewis, The Lion, the Witch, and the Wardrobe
