Dorvin stands with the stillness of a plumb line, shoulders squared as if a formal hearing might begin at any moment. His dark hair is cut close at the temples, while the top is combed into a precise ridge that has begun to silver. His eyes are a clear, mineral gray, alert to the small movements of a speaker's hands. The skin across his knuckles is densely callused and stained with fine black scoring from years of handling warding diagrams and measuring instruments. He walks with short, economical steps, never seeming to hurry, yet arriving exactly where he intended. A tiny brass wind-up bird, improbably cheerful and chipped at the beak, rides in his breast pocket; he winds it before difficult hearings.

Dorvin is patient with careful uncertainty and merciless toward confident claims that have not been tested. He prizes impartiality, yet remembers every person harmed by a supposedly neutral procedure. In ordinary conversation he can be unexpectedly wry and even fond of small mechanical toys; under pressure he becomes exacting, separating testimony into fact, inference, and proposed action. He dislikes being treated as an oracle, but quietly fears the moment when nobody else can make the decision.

Dorvin was raised among the Conclave's clerks and ward-surveyors, where a miscopied figure could place a whole settlement in danger. As a young examiner, he found an error in a containment calculation and insisted it be corrected before a ceremonial inspection. The correction delayed the inspection, exposed a concealed failure, and saved the ward crew. His mentor, who had suppressed the discrepancy to protect a senior official, lost her post; she later taught Dorvin that a defensible truth can still ruin the person who speaks it. Years later, during an emergency at a remote sky-anchor, Dorvin held a failing ward with his own prayers while waiting for a second authority to countersign the repair. A worker died before the countersign arrived. Since then, he has demanded evidence and procedure, yet privately carries the authority to act without further approval. He has come to Zephyria to assess the Atmospheric Containment Matrix and the readings surrounding the Ring. He refuses to endorse either Tectonic Cult faction without proof, while exchanging terse letters with his former mentor, who now urges him to trust people before instruments.
