Broken Shore

From PathfinderWiki

The Broken Shore is a mile-wide sea of hard black glass and sand that ripples out in concentric circle patterns located in the Algid Wastes, on the amorphous border between the northern Hold of Belkzen and the Realm of the Mammoth Lords. On its edge stand statues of forgotten gods, and it is avoided by both the Kellid tribes of the Realm of the Mammoth Lords and the orcs of Belkzen, who know it to be haunted.1
