Narevi looks built for crossing a town before its gates open: compact, spring-loaded, and always occupying slightly more space than a person expects. Sun and road dust have left their brown skin with a dry, finely cracked texture across the bridge of the nose and forearms, while rain-darkened cuffs are permanently stained with grit. They plant each foot as if testing a bridge plank, then dart forward in sudden, economical bursts. Their most unexpected feature is a tiny, carefully embroidered sprig of blue flowers on the inside of their battered runner's cap, a keepsake they touch before every warning run.

Curious and quick-moving, Narevi is generous with time when someone is frightened or lost, yet sharp and impatient when a meeting circles around a decision. After a close call, they become unusually methodical and ask everyone to repeat instructions back. When relaxed, they tease friends and collect small bits of local lore; when tired, they turn every conversation into a route plan.

Narevi grew up in a settlement where every warning arrived late, if it arrived at all. As a child, they ran messages between the river landing and the hill homes for their aunt, who organized neighbors to share food and shelter during floods. One spring, Narevi carried an old bell code that had been altered without their knowledge. The signal sent families toward a low crossing just as the river rose. No one died, but several homes and the settlement's grain store were lost. Narevi's aunt, Omi, taught them to listen before they ran again. Years later, Narevi helped form the Bell-Keepers, a mutual-aid and civil-warning association, and became its Road Runner coordinator. They now maintain routes, train messengers, and argue with elders who insist that every new signal wait for a full council vote. Their current trial code uses paired chimes and shutter flashes to distinguish fire from flood. Narevi wants to test it in a controlled drill before the next storm season, while elder Koyo fears the code will be misunderstood and carries guilt of his own for approving the old one.
