The Primordial Splinterwas a pact between Mephirouth and Surtur. It was formed to undertake the grueling process of Ascension. On 9 Kindle 1301 HE, they made Rioch Tetrax a Higher Power. Like in the case of the Gray Block, their reason for doing this is not clear. Some say both wanted to get their hands on the Durkoth Saint's Torc of Maen Grirngrim, a device that seemed to be tied to the soul.
