Petru looks like a young Baltic man, lean and slightly long-limbed, with wind-reddened cheeks and a habit of standing as if braced against a ferry deck. His dark hair is cut with almost fussy precision at the sides, but the top keeps falling into his eyes; he pushes it back with the heel of his hand. Before he speaks, he takes a small, audible breath through his nose, as if checking whether the air is safe. His movements are quick and protective, often placing himself between other people and a doorway without seeming to notice. The unexpected detail: he keeps a tiny, carefully polished wooden toy duck tucked into his coat, and handles it with the solemn attention of a shrine object.

Petru is earnest and impulsive, protective of strangers yet uncomfortable when anyone tries to protect him in return. In a crisis he becomes decisive and warm, making other people feel there is a plan even when he is improvising. In quiet moments he is apologetic, watchful, and prone to examining every word he said for signs that he promised too much. He wants to trust people, but distrusts his own memories.

Petru remembers being a man in a place that was not Latvia, though the details of that life come in disconnected flashes: a kitchen window full of winter light, a name he cannot retrieve, and the certainty that he once belonged somewhere. He came to himself beside a drainage ditch outside a Latvian town with no papers, no local language, and a coat that fit him as if it had been waiting. A widowed market seller, Maija, took him in for one night; he stayed long enough to learn Latvian from her customers and to become useful carrying crates. His first formative turning point came during a spring flood, when he promised a group of displaced travelers he could get them across a flooded road. The water rose faster than he expected. He got them out, but only by abandoning his own pack and nearly drowning. Since then he promises quickly, as if delay itself might cost someone their chance. Petru became part of the Red Thread, a clandestine circle of displaced friends and mutual aid. He helps newcomers find beds, work, and safe passage, while quietly trying to discover why he has no traceable past. Maija worries that his self-sacrifice is becoming a habit. A traveling naturalist, Oskars, has begun asking why stray dogs and crows watch Petru in silence. Petru is afraid the answer may be that he is not wholly human, though no evidence confirms it.
