Orvo is a weather-browned woman with a broad, steady stance and a slow, deliberate way of turning her head, as though she is always measuring where a sound came from. Her hands are thickened and ridged from years hauling bell ropes, with pale rope grooves and dark grease worked into the creases. She keeps her silver-black hair meticulously combed into a precise braid, an unexpectedly fastidious habit for someone who lives in salt spray. When she walks, she places each foot as if testing a deck for its roll, leaving the impression of a woman who can hear a storm before anyone else sees it.

Orvo is welcoming and generous with anyone who respects the work, yet sharply skeptical of confident guesses. She enjoys teaching, but becomes controlling when Dara takes risks. In calm weather she tells dry, amusing stories; during a storm she becomes intensely focused and leaves no room for banter.

Orvo grew up in the cliffside hamlet of Siltstep, where her mother repaired nets and her father maintained the warning bells. As a girl, she learned to distinguish a fishing lugger from a grain barge by the different echoes of their hulls beneath the headland. At nineteen, she misread a fog-muted signal during a squall and sent rescuers toward the wrong inlet. Her younger brother was among the sailors lost. The failure changed her from a quick, confident listener into a patient, exacting one; she now checks every impression against wind, tide, and a second sound. She has spent decades maintaining the coast's bells and teaching the same listening craft to her daughter Dara. Their bond is loving but strained: Dara wants a life beyond the cliffs, while Orvo quietly depends on her to inherit the work. A recent crack in the oldest bell has made its alarm unreliable, and Orvo is hiding how close it is to failing.
