The Stone Road penetrates the Bone Mountains from Vaes Jini, once known as Yinishar, leads to Kayakayanaya, which lies on the eastern side of the Krazaaj Zasqa. The Great Sand Sea is to the east of the city.
The walls of Kayakayanaya are black basalt, black iron, and yellow bone.
The city is known for its warrior maids who wear iron rings in their nipples and rubies in their cheeks, similar to those of Bayasabhad and Shamyriana. It is said that these cities are defended by women out of the belief that only those who give birth are permitted to take life at will.
Like its sister cities, Kayakayanaya is ruled by the Great Fathers. Their daughters learn to ride and climb before they learn to walk and are trained in the arts of bow, spear, knife, and sling from the earliest age. Meanwhile, ninety nine of every hundred boys, the sons of the Great Fathers, are gelded when they reach the age of manhood and live out their lives as eunuchs, serving their cities as scribes, priests, scholars, servants, cooks, farmers, and craftsmen. Only the most promising males, the largest, strongest, and most comely, are permitted to mature, breed, and become Great Fathers in their turn. Maester Naylin in his Rubies and Iron speculates on the circumstances that led to such customs.
