|“Sing the song of the Ancient Stones and the blood of the beast imbues your bones.”
The Stonekeepers used the Ancient Stones to create Gnag the Nameless's army of Fangs. They had the person that was to be melded with an animal sing the Song of the Ancient Stones and then expose them to the light of either the Holoré and Holoél. They also did this with cloven. After the Wingfeather War, they melded themselves with sea creatures using the Third Ancient Stone. They died soon after.
