A large territory comprising of green steppes in a center strip, unforgiving mountain ranges along the west making a natural border that prevents access to a large sea aside from a chokepoint that allows entry to the region, many winding canyons and valleys to the southeast, lush flowing rivers coming in from the north that drain to the southeast, the southwest a dusty and hilly region, and northeast an inhospitable desert that gets covered in snow during Winter. Within this are three loose ethnic territories united by a network of 5 major ceremonial cities and trading centers a la Persepolis. Mongoloid, Nordid, and Semitic traders pass through commonly through the northeast and north with a good portion laying down roots.
Non-descript Aryan/Slavic hunter-gatherers that live mostly nomadic lives and are the major demographic living on the steppe and dusty hills, settle down in a new place once a year to farm and move on leaving some permanent structures, omnivore diet, uses wagons and horseback to transport, weak central culture and no dominant religion. Caucasians who are mostly nomadic in the lower mountains and bases with some and eat nothing but meat and dairy, make up the majority transport themselves by horses, few worldly possessions, regard themselves as a specialty warrior society like Cossacks. Iranian type of people who live in caves and crude houses in the valleys and canyons and to the northeast, pescetarian diet out of circumstance with red meat being a luxury, wary of outsiders and don't interact with one another as much as the other three do, have basic boats for lakes and rivers, modes of transport is yak and camel.
Religion are largely shamanistic and monotheistic with a minority of a polytheistic one and and eastern philosophical religion.
The rule of law is laid down by the king who below him has governors and tribal leaders who pay tribute to him based on their possessions in coinage. While it doesn't matter what religion and race the king is he has always been one of the Aryan hunter-gatherers and practiced the monotheistic religion.
Architecture is a mix between Armenian, Kartvelian, and Iranian styles with basic mudhuts and strawhuts.
The language is masculine, smooth, and consonant-heavy, a mix of Yaghnobi and Kartvelian with an alphabet that mimics that of the Semites' but there is no uniform one due to traders and learning what each sound makes then transmorphing to their own; from west to east it shifts from cuneiform to phonetic.
