A compact, slightly forward-leaning man whose movements have the economical starts and stops of someone forever counting steps between wagons. His skin is weather-browned, with a pale strip across his brow where his cap usually sits. His jaw is broad and works side to side before he answers difficult questions; when he eats, he chews with his lips tucked tight, exposing small, crowded teeth. His laugh is a sudden bark that reveals one conspicuously gold-capped canine. A battered brass measure hangs from his belt, polished bright only along the thumb groove where he rubs it when frightened. He leaves the impression of a man trying to make himself smaller without ever losing sight of the exits.

Tovin is methodical but not cold; he can remember exactly how much flour remains while failing to say the kind thing someone needs. He is eager to be useful and resentful when people treat him as disposable. In ordinary company he makes dry jokes and offers practical comforts. Under scrutiny he becomes defensive, overexplains mundane details, and hides behind arithmetic. Around the injured, his brisk manner softens into attentive patience.

Tovin grew up weighing salt and dried fruit at a roadside store, learning early that a quarter-ounce mattered more to a hungry traveler than a grand promise. He joined caravan work as a young adult and became indispensable by remembering which axle groaned, which mule balked at smoke, and how much food each wagon actually carried. Years ago, during a winter crossing, he argued to press on despite a storm. A wagon overturned in a ravine and his younger brother, Perren, was among those killed. Tovin has since kept meticulous tallies, partly to prevent another disaster and partly to convince himself that numbers can keep people safe. Recently, pressed by debt and threatened with the loss of his home, he sold a copy of the caravan's route and guard schedule to an intermediary. He told himself it was only a warning meant to delay the train. The attack at Ember Pass proved otherwise. He is now trying to help the survivors while quietly steering suspicion away from the quartermaster's records. His former mentor, Senneth, still trusts him; his estranged sister, Briska, has come to the pass looking for answers about the leak.
