Patrimony of Hyrkoon
It was centered around a fertile area of rivers and lakes, since desiccated to become the Great Sand Sea, a time known as the Dry Times. The fortified cities of Kayakayanaya, Samyriana, Bayasabhad, and were once part of this great nation, each guarding the Steel Road, the Stone Road, and the Sand Road, respectively, from brigands, outlaws, and wild men of the Bone Mountains, and the savages that dwelt beyond them.
Before the Dry Times, the Patrimony fought a savage border war with the Jogos Nhai, who poisoned rivers and wells, burned towns and cities, and carried off thousands into slavery on the plains. The Hyrkoon, for their part, were sacrificing tens of thousands of Jogos Nhai to their gods. This enmity survives into the present, with Jogos Nhai jhattars leading attacks on Kayakayanaya.
The custom of having warrior women, who fight bare-breasted and pierce their nipples with iron rings and cheeks with rubies, shared by the above cities, possibly originates in the Patrimony. West of the Bone Mountains, the city of Yinishar, now the ruins of Vaes Jini, may have been connected with Hyrkoon, as the people of Yinishar were akin to the people of Samyriana.
