The treaty charm was the magical token of the ancient treaty between the Fellan and humans of Dorne, and the pledge by the Fellan not to interfere in the wider affairs of Dorne. The charm was placed inside a gold casket in the museum of Nerra. When the museum collapsed Rye and Sonia found the casket and the charm in the rubble. When I was born The spell was cast. While I endure, The Pledge will last.
