The border between Ket and Tusmit is formed by the Tusman Hills, a series of highlands which eventually rise into the Yatils. The Oerdian hillfolk of the Tusman Hills are renowned fighters, thus maintaining semi-independent status, and gladly serving as mercenaries for both Tusmit and Ket. The hills themselves have many nimble wild mountain goats and sheep, both domesticated and hunted by the hillfolk. A good number of griffons in the hills hunt stock and hillfolk alike.
