Clementine Flock has long blonde hair, usually braided into a thick rope that is looped over one shoulder so it cannot catch on a door latch or an opponent's hand. Her blue eyes hold a sharp, glassy focus when she is examining someone, and her pale skin is weathered at the bridge of her nose from years outdoors. She moves with a patrol officer's clipped economy, then pauses abruptly, as if listening for a sound no one else can hear. An unexpected softness in her severe uniform is a small, carefully mended patch of embroidered yellow flowers inside her coat cuff, visible only when she reaches for something.

Clementine is methodical and skeptical on duty, but unexpectedly patient with frightened witnesses and children. She wants to trust people, yet keeps testing their stories because she has seen how easily a false face can put a town in danger. When calm, she can be wry and companionable; when a case touches her father or the old barricade, her questions become relentless and her judgment narrows.

Clementine grew up above a shuttered watchmaker's shop in Pennytown, where her mother repaired clockwork and her father served as a night watchman. At sixteen, during a winter evacuation, she saw a frightened child walk through a barricade that should have stopped him. Her father's hand passed through the child's sleeve; the child was a magical disguise laid over a smuggler carrying a stolen seal. Clementine's first uncontrolled burst of magic exposed the deception, but also set fire to the barricade and injured two guards. Her father took the blame for the breach and lost his post. The incident taught her that appearances can be weapons, and that a correct suspicion can still hurt innocent people. She trained as a town guard and learned to direct her sorcery rather than fear it. Now she patrols the market wards, quietly comparing official faces with what her Pennyeye can sense. She owes her position to Captain Shirin, who defended her after the barricade incident, and distrusts Sthen, a traveling illusionist who insists the old case was staged. Her current problem is a string of false identities appearing in town records, each attached to someone who has vanished.
