Oki

Oki is a northern forest-and-valley region where survival depends on reading animal behavior, seasonal movement, and the terrain itself. Its woods offer shelter and sustenance, but they are not passive scenery: pyuika range through them according to ingrained habits, while the spread of disease across Oki and other parts of the former Aquafa makes the region part of a much larger epidemiological mystery.

Setting and Regional Reach

Oki encompasses forests in the north and a valley where displaced Ahfal Oma established new lives as nomadic herders and hunters. Their adaptation was easier than that of many of their people who had taken up unfamiliar occupations elsewhere, but the change was not simple: reindeer and pyuika differ substantially from horses, and northern Ahfal Oma became better known as hunters than herders. The region’s familiar landscape offered continuity with their former way of life, without making its animals interchangeable with the livestock they had once known.

Oki also occupies an important place in the geography of the Mittsual investigation. A map of suspected cases showed people with mittsual-like symptoms from the Yukata Plains in the south to the Oki forests in the north, including cases that predated the salt-mine disaster. The oldest reported case was eight years earlier. The evidence did not establish that every case had the same cause, but it made Oki one end of a distribution too broad and too old to be explained only by the more recent outbreak.

Pyuika and Forest Knowledge

The forest is a working landscape for pyuika herders. Pyuika bonds formed when an animal was young could endure for life: a bonded animal would answer its keeper’s whistle and could become lonely when separated. Their attachment had a visible sign, too; butting was affection, and Tsupi’s repeated nudges showed Van that she had grown attached to him. Far from home and without other pyuika in the woods, she had reason to seek his company, though the autumn mating season complicated the search. The scent of a bull elk had apparently put her in heat, drawing her into the forest in search of him.

Control of pyuika depended less on confining them than on understanding their aversions and customary routes. Mohoki, a lichen growing on old trees, repelled them so strongly that braided, dried strands could be tied around a fence to keep them penned. The same knowledge could guide their movement without a fence: pyuika migrated seasonally but habitually followed well-worn paths, and planting mohoki at strategic points could redirect them. Because enclosure was unnatural for these vigorous, free-ranging animals, they were better allowed to roam during the day and kept in pens at night when wolves posed a danger. A fence without an escape route could leave them in decline.

That expertise began in childhood. In the Toga Mountains, boys accompanied the men into the forest and watched the pyuika herd at close range, learning to recognize the animals’ habits and how selected fawns were trained and bonded to human keepers. Wild pyuika did not readily grow accustomed to people once mature, so familiarity had to begin early and the personal bond had to be carefully nurtured. Van could draw on this inherited practice when he tried to locate Tsupi: he read faint hoofmarks and the smell of urine left by a frightened pyuika, and knew that she was unlikely to have gone far.

Seasonal Herding and Migration

Oki’s ecology also sets practical limits on keeping pyuika and reindeer together. Van argued that the pyuika should be allowed to roam freely in spring rather than being treated as livestock under constant restraint. Their range was relatively narrow compared with the great distances traveled by deer through deep-snow country, perhaps because pyuika could eat a wider variety of foods. Familiarity with their habits made it possible to predict where they might be without forcing them onto a herder’s schedule.

The animals’ breeding cycle sharpened the conflict between two ways of keeping stock. The reindeer’s migration to summer pasture coincided with the pyuika calving season. In the previous year, the pyuika had borne no young, and Ohma’s family had simply hitched them to a rope and led them after the reindeer. Van suspected that the stress of this unnatural rhythm had contributed to their failure to breed. Yet the reindeer could not remain in their winter grounds: summer brought swarms of horseflies and mosquitoes, while the grasses there were thin. They needed the summer pastures, where sea winds drove away pests.

The family answered the problem through cooperation rather than by forcing both species into the same pattern. At Tohma’s suggestion, they asked neighboring Zolian immigrant families for help. Those families had struggled to breed pyuika themselves and were eager to learn from Van. Three of Kiya’s nephews stayed with Van and Tohma to study pyuika raising, while the others took the reindeer to their regular summer pasture. The arrangement connected local knowledge with the region’s wider community, and gave the pyuika a chance to remain on a schedule better suited to their needs.

Disease, Refuge, and Narrative Significance

Oki’s forests are linked not only to animal migration but also to an unsettled pattern of illness. Investigators found reports of mittsual-like symptoms across the former Kingdom of Aquafa, with the northern Oki forests at the far end of the known range. Hohsalle cautioned that a distribution like this would be difficult to explain if wolves and ossam were the only carriers; a migratory bird might also be involved. This was a possibility, not a confirmed source, but it widened the inquiry from local animal bites to transmission capable of crossing long distances.

At the same time, Oki offers refuge to people seeking healing. Patients at the Echo Master’s cave included Zolian immigrants, who came there despite having healers of their own after hearing of his skill. Their presence complicates any simple division between communities: the region’s medical reputation drew people across political and cultural boundaries even as the suspected disease linked far-flung settlements in a different, more troubling way.

Oki therefore brings the book’s ecological and human histories into the same terrain. Knowledge of pyuika behavior can prevent distress, sustain breeding, and allow herds to roam; imperfect understanding of animal transmission, by contrast, leaves communities unaware of how widely an illness may already have traveled. The forest is at once a place of practiced coexistence, a home for displaced people, and a northern marker in the search for the disease’s reach.
