The fabled "Wolf-land" of demons and sorcerers, Hyrkania has vast subhumid to semiarid tract of prairie, steppe, high desert, taiga forest, and tundra lying east of the Vilayet Sea, west of Khitai, and north of Vendhya and Meru.

The northern coast of the Vilayet is described as marshy, with snow-gleaming mountains far to the north. South of the mountains are hills, home to the dreaded savarysk, the cannibal-horse of the northern steppe.

In Conan's time it had many city-states, more or less firmly under the control of the Turanian Empire. Autonomous regions were situated along the northeastern shore of the Sea and deep into the interior, with Turanian vassals along the southeastern coast and the eastern caravan routes.

The Hyrkanians were ancestors of Lemurian people who moved into the arid eastern center of the world-continent long after their chain of islands sank during the Cataclysm. They freed themselves from servitude in ancient Khitai and began to dominate the steppes and deserts west of the Great Wall. Eventually, some of these northern Lemurians invaded the western reaches of the continent and became the ancestors of the Acheronians.

Others stayed in the Hyrkanian steppe, apparently living in enclaves among the many aboriginal tribes, until after the establishment of the Hyborian Kingdoms. Then a southern Hyrkanian clan migrated around the southern end of the Vilayet Sea and established the kingdom of Turan.

Other Hyrkanians made periodic forays around the northern end of the Vilayet to harry the outposts of Hyperborea.  In Conan's time, citizens of the Turanian Empire were proud of their Hyrkanian heritage and likely to refer to themselves as Hyrkanians.
