Otar looks like a young man dressed to cross a winter pass, but his stillness gives him away: he holds himself as if listening to weather no one else can hear. His brown hair lies in uneven, wind-combed layers, and his pale yellow eyes have the hard, fixed focus of a hunting eagle. His skin has the gray-pink cast of someone long chilled, and his breath arrives as a thin plume even beside a hearth. He moves with economical, ground-covering strides, then stops so completely that a conversation can seem to have lost him. An unexpected detail: he keeps a tiny paper notebook of bird silhouettes and draws them with fussy precision, like a patient schoolboy rather than a revenant with a hunting curse.

Otar is considerate in practical ways but guarded about affection, and he is capable of sudden tenderness followed by an abrupt retreat. He likes predictable systems yet keeps choosing the most dangerous uncertainty: learning who he was and meeting the father he expects to kill. When calm, he is dryly funny and willing to explain a difficult calculation. When threatened, he becomes direct and unsentimental. When grief catches him off guard, he tries to turn it into a list of tasks.

Otar was born across the sea to a family whose names and faces he remembers in scraps: blond hair, blue eyes, a father's hand closing around a door latch. He was taken from that life as a child and raised by a kind, practical household in a cold inland settlement. He learned to be useful before he learned to ask where he came from. His talent for mathematical statistics grew from helping a local business compare shipments, weather losses, and seasonal demand; he found comfort in figures because they made uncertainty legible. As a youth, he died in a winter disaster whose exact circumstances he refuses to recount. An eagle spirit answered his plea or chose him, depending on which fragment of memory is true. Otar gave up his blue human eyes in exchange for the spirit's golden sight, and returned to life with brown hair, cold breath, and a second presence inside him. The same spirit now drives his dreams with images of war, wind, and lightning. The change unsettled his adopted family. He left after a bitter argument, telling himself that a hunt had called him and that distance would spare them. He seeks his blood father, whom he intends to confront, though he expects the meeting to end in murder. He is also beginning to understand that the power growing in him carries a price, and that his revenge may be only the first demand.
