Hyrkoon is a region in the further east of Essos, on the eastern side of the Bone Mountains. It is thus located far to the east of the Dothraki Sea, and northwest of Yi Ti. City-states such as Bayasabhad and Samyrian are located in Hyrkoon. Hyrkoon is famous for its fierce warrior-women, who are known for their decorative body modifications. The warrior-women of Hyrkoon go about bare-breasted with iron rings through their nipples, and rubies studded into their cheeks.
