Shirin is a healthy, exceptionally handsome young man, with the local features and bearing of the people around him. His face is open but observant, and his steady gaze tends to settle first on a person's hands, breath, and posture. His dark hair falls forward in a stubborn wave that he repeatedly tucks behind one ear. He moves carefully through crowded spaces, still learning the habits expected of a young man in this body, and carries his shoulders as if making room for a self that has not changed. His wool clothes are plainly mended and sit a little awkwardly at the shoulders, but he keeps one small linen pouch meticulously clean. He smells unmistakably of dried herbs, wool, and the sharp, animal warmth of a stable, and seems not to notice.

Quiet and empathetic, but not credulous: Shirin listens warmly and notices inconsistencies without turning every conversation into an interrogation. With frightened people, they are patient and gently practical. With someone exploiting another person's trust, they become unexpectedly direct. In private, uncertainty about their new body's customs can make them self-conscious; under pressure, that self-consciousness gives way to focused competence.

Before the catastrophe scattered the Seven Marks, Shirin was an American veterinary assistant, accustomed to quiet work: cleaning kennels, preparing instruments, and noticing which animal had stopped eating. Shirin woke alone in a damp clearing in the lands that would later be called Latvia, among communities neighboring powers dismissed as wild and pagan. The unfamiliar language, clothing, and body made every ordinary task a negotiation. Shirin remembers having been a woman and does not consider that self changed, even while understanding that strangers now see and treat a young man. A local healer, unsettled by Shirin's arrival but moved by their care for a feverish dog, taught them enough words and customs to survive. Since then Shirin has become the fellowship's keeper of health and confidences, tending blisters, fevers, and the silences people keep after the catastrophe. The Seven Marks remain scattered, and Shirin has no reliable way to find them. The healer expects Shirin to remain and help through a hard winter; Shirin has promised to do so, even as every rumor of another displaced American pulls them toward the road.
