Olyra has a compact, square-shouldered presence and moves with the efficient, measured pace of someone who has spent years carrying stores through a crowded camp. Her brown skin is often smudged with flour at the wrists and marked by fine blue-black ink along the sides of her fingers. She keeps her dark hair cropped close at the nape and bound in a practical twist, with each strand deliberately in place. Her gaze travels from faces to hands to whatever paper lies between them. Unexpectedly for a ration-master, she carries a tiny wooden flute and plays it badly but cheerfully while counting sacks. When rattled, she takes one sharp breath through her nose, then resumes speaking without losing her place.

Olyra is fiercely protective yet distrustful of anyone who offers protection in exchange for obedience. She is patient with tired workers and merciless with careless arithmetic. In a calm conversation she can be wry and generous; under pressure she becomes clipped, procedural, and unwilling to let a speaker move on until every number is accounted for. She wants the truth brought into the open, but her instinct is still to shield the camp from consequences until she can control them.

Olyra learned to count before she learned to read. Her mother kept stores for a caravan crew, and Olyra grew up watching a missing scoop turn into a hungry household by nightfall. At Plenty's End she became the camp's ration-keeper, recording each issue and each disputed claim in a hand so clear that even exhausted workers could check it. Years ago, a Claimholder's agent presented a contract that appeared to grant the camp dependable access to a shared water channel. During a dry season, Olyra found a clause that let the Claimholders suspend that access whenever their own crews declared a shortage. By then, the channel had already been diverted. The camp's elders urged her to keep the discovery private until the next supply shipment arrived. Olyra obeyed, and watched families spend their remaining water on crops that could not survive. That failure changed her: she now believes a truth kept from the people it harms is another kind of theft. She wants the original contract examined in a public forum, but she still controls daily food and water allotments, and fears that a reckless disclosure could leave workers with no provisions at all. She is close to the camp's night watch, distrustful of Claimholder representatives, and regularly argues with the elders who once asked her to wait.
