Tyvian culture is one that mixes survivalism and refinement. While Tyvia is cold and boasts a hostile ecosystem, its residents are known to be skilled in the culinary arts. In particular, Tyvian foods (such as whale meats and fine wines) are exported all over the Empire, and are enjoyed by both commoners and nobles alike. Tyvian art, from architecture to fashion, has been described as "ornate and complex".
Tyvia also produces exceptional metal ore, something sought after by Piero Joplin due to its superiority over Gristol's native metals. The Overseers of the Abbey of the Everyman also use Tyvian ore to craft their sabres.
The Isle of Tyvia suggests that the nation maintains a somewhat isolationist standing, claiming that "Tyvians are proud of their customs, food and history, and have little concern for the Isles to the south". However, the book also notes that the people of Caltan share much with those from the isle Morley, which stand in close proximity.
As a result of Tyvia's alliance with Gristol to stop the Morley Insurrection, Tyvia was granted a certain autonomy from the Empire by its recent rulers. This allowance further expands Tyvia's independence, both culturally and politically.
Tyvia is ruled from the Citadel of Dabokva, within the People's Chamber. It is in here where a small council of sixteen sits, called the Presidium, made up of eleven men and five women. They are obedient to the High Judges, each a Secretary for the People of Tyvia. Council members are voted in democratically, however there is only one political party, fielding one representative from each district of Tyvia.
The High Judges hold the real power, also ranked as "Secretary for the People of Tyvia", they are considered senior council members. They rule Tyvia with an iron fist, they themselves being set to three members:
- Secretary Cushing
- Secretary Taren
- Secretary Kalin
- "[…]we sentence you to a lifetime of freedom."
- —Secretary Kalin
Tyvia utilizes penal labor camps located in the nation's center for incarceration, some of which have no surrounding walls to contain prisoners; a prisoner is considered free if they choose to flee. However, due to the area's harsh climate, no escaped prisoner has survived the trek to civilization in recorded history. The prison guards' only functions is to keep order in the camps and to punish prisoners who did not fulfill their job quotas, as they are ordered not to stop fleeing prisoners. 
Varying in size, ranging from small camps of a few dozen convicts to prisons the size of a small town. They also ranged in functions. Convicts of lesser offenses are doomed to harvest lumber; but lumber camps were not penitentiaries, merely "correctional" facilities. Prisoners might even one day return to society - a ghost of their former self, their rebellion worked out of them. Other prisons exist, such as quarries or mines. Utyrka being an infamous salt mine, to be sent to one of these camps would be to disappear. But, to be sent to a prison camp is to be granted freedom.
Prison guards wear the uniform of the Tyvian army, consisting of a fur-lined greatcoat, a wide-brimmed hat, a scarf woven from the pelt of a saber-toothed black bear and red snow goggles.
