The Oki Region is the northernmost part of Aquafa, a frontier landscape where seasonal movement and intimate knowledge of animals are essential to survival. Its winter valleys protect reindeer from heavy snow, while the forests and hills support pyuika; the different needs of these herds make the region a testing ground for Van’s expertise and for the families who hope to build a livelihood there under Zolian rule.

Setting and Seasonal Life

Almost two months after Van and Tohma met near the salt mine, they reached Tohma’s family home in the Oki Region before the first snowfall. The family used the valley as its winter home, moving in summer across the mountains toward grasslands and hills nearer the sea. The winter camp lay on a gently sloping dale beside a river, somewhat warmer than the basin below. Mountains screened it from winter clouds, limiting the snowfall so reindeer could paw through the snow to reach the lichens they preferred.

The valley was part of a rotating grazing system, not a permanent pasture. Lichens grow slowly and take several years to recover after being eaten, so herders shifted their winter camps between sites and would not return to this one for years. Van recognized a parallel with his own people’s seasonal migration with pyuika, but also a crucial difference: the plants pyuika favor grow back quickly enough for Van’s people to revisit a grazing ground each year. The region’s livelihoods therefore depended not simply on moving animals, but on understanding how each herd affected the land it used.

Herding Knowledge and Adaptation

Van’s knowledge was rooted in the Toga Mountains, where boys learned pyuika habits by accompanying adults as the animals roamed. He understood that pyuika were too wild to manage like ordinary livestock: the answer was to let them range freely and accustom them to people through bonds formed from an early age. In spring he persuaded the Oki herders to release their pyuika rather than keep them restrained, despite their fear that the animals would not return. Pyuika range more narrowly than deer, and herders familiar with their habits can predict where they are likely to be. Their seasonal paths and enduring attachment to the people who raised them made a different kind of husbandry possible.

The practical details mattered. Pyuika can be guided by placing mohoki, a lichen they avoid, along their customary routes; dried mohoki braided into ropes can also help keep them within a corral. Without this knowledge, penned pyuika might escape or decline. Even with an effective enclosure, they were better allowed to roam during the day and kept in at night when wolves were a danger. Van’s expertise was not a generic skill in animal raising: it depended on knowing the animals’ particular preferences, movement, and social behavior.

Seasonal rhythms also complicated efforts to raise pyuika alongside reindeer. The reindeer’s move to summer pasture coincided with the pyuika calving season, and in the previous year the pyuika had borne no young. Van suspected that being made to follow the reindeer on a rope had imposed an unnatural rhythm and contributed to the breeding failure. Yet reindeer could not remain on their winter grounds through summer: thin grasses and swarms of horseflies and mosquitoes made a move to sea-breezed pastures necessary, even though reindeer could eat a broader range of food, including mice and insects.

The family and its neighbors responded by dividing the work. Three of Kiya’s nephews stayed with Van and Tohma to learn pyuika husbandry, while the others took the reindeer to their usual summer pasture. Kiya remained to care for Yuna. Van’s instruction represented an attempt to adapt the division of labor to two different herding cycles, rather than forcing one herd to conform to the other’s needs. The outcome mattered to the family’s prospects: successful calving and future breeding could help them raise enough money to sustain themselves.

Winter care demanded further specialized labor. During mating season and pregnancy, pyuika ate ashimi, a green lichen that could still be gathered fresh beneath the frost. Herders collected it from the woods, digging through deep snow and carrying it back for the animals, because feeding it to the does was considered important to producing strong calves. Van could locate ashimi by smell, making a difficult winter task easier. The land’s resources thus entered husbandry not as interchangeable forage but as particular materials with distinct effects on the herd.

Families, Markets, and Imperial Rule

The Oki Region’s herders faced economic pressures as well as ecological ones. Tohma’s family was poor, and a head tax applied to every reindeer. Rates were lower for people with Zolian blood, but this benefited only Kiya and Tohma and did little to relieve the family’s overall burden. In desperation, Ohma sold some reindeer and tried to raise pyuika, which were taxed less. Because the family lacked the knowledge needed to raise and breed them, those efforts failed, leaving the household close to disaster.

Van’s arrival offered the family a chance to avoid seeking aid from the wider clan. Tohma had bought provisions with money from selling furs, and the family’s relief at the supplies was inseparable from its hope that Van could help them make pyuika husbandry work. With winter approaching, Van took on preparations for the household: he cut, hauled, split, and stacked firewood, while Tohma, whose injury prevented heavy outdoor work, sharpened hunting knives and prepared traps. The knowledge Van brought was therefore joined to immediate labor and to a collective effort to get the young and old through winter.

The region’s economy was also changing under Zolian influence. In Aquafa, cheeses and yogurts had traditionally been made from reindeer or mare’s milk, but cow and sheep products brought by settlers from Zol were cheaper and easier to obtain. Oki laputa, a cheese made from reindeer milk, had become difficult to find in Aquafa’s taverns. The changing market reflected a broader shift in livestock and political priorities: Makokan suspected that reindeer numbers might be declining as the Zolian army promoted pyuika breeding to strengthen defenses along the mountainous frontier facing Mukonia.

These changes took place within a system that made remote communities legible to imperial administration. Zolian tax officers collected information even about nomadic groups in the Oki Valley and recorded the population and ages of each community. The records were accurate enough to support efforts to locate people such as Van, though some could hide in the woods when officers arrived. Taxation and population records linked the valley’s dispersed families to a state interested in managing both people and frontier resources.

Frontier Identity and Significance

The Oki Region’s position within Aquafa did not erase the distinctions that structured life along the frontier. Under Zolian rule, families of differing ancestry faced different tax burdens, while the empire’s expansion also relied on poor farmers and herders being settled in conquered territories to cultivate Zolian-preferred crops and livestock and establish Zolian-style communities. The settlers benefited from lower taxes and land of their own, but many grieved the loss of their homeland. In the Oki household, these wider pressures intersected with family loyalties, mutual aid, and the practical need to make a mixed livelihood work.

The valley’s significance lies in that intersection. Seasonal pasture, slowly recovering lichen, pyuika behavior, reindeer migration, and imperial taxes are not separate background details: together they determine whether a household can endure. Van’s local knowledge creates a possibility of survival, but adapting it requires cooperation across families and between herding traditions. The Oki Region is thus both a specific working landscape and a frontier being reshaped by settlement, administration, and changing demands on its people and animals.
