Pella stands square to the communications console, but keeps her weight poised on the balls of her feet as if the floor might shift beneath her. Blue instrument light catches the fine silver threads woven through her dark hair and the faint ridges left by years of headset pressure above her ears. Her gaze rarely settles on a face; it checks mouths, hands, exits, and the status lamps beyond a person's shoulder. She moves with a careful, economical stillness, then makes abrupt precise gestures when a signal breaks through. Her unexpectedly conspicuous detail is a tiny paper crane tucked beneath the clear cover of her headset case, creased from a child's drawing and utterly out of place among the sealed equipment.

Pella is disciplined enough to trust a well-tested procedure and humane enough to break one when a real person is in danger. In routine work she is dry, exact, and quietly funny; during emergencies she becomes blunt and intensely decisive. Afterward, she can be evasive about her own feelings, though she is patient with other people's fear. She wants to believe evidence will settle every argument, but has already made one life-changing choice before the evidence was complete.

Pella Kett grew up in a coastal town where storm warnings arrived late and families learned to read silence on the radio. She trained as an Earth communications controller, first handling remote research stations, then taking a position supporting lunar expeditions. During the disastrous Hushfall Relay outage, a rover crew lost contact while a solar storm scrambled telemetry. Pella had to choose between following the approved relay reset sequence and routing a weak signal through an untested antenna. She chose the risky route and brought the crew home, but the delay cost a technician on the surface a chance to reach shelter. Since then, she has kept the rescued crew's cracked mission patch beside her console and refuses to call a delay 'just procedure.' Her former mentor, Oona Vey, now oversees the Earthside control shift and thinks Pella's judgment is dangerously personal. Pella also exchanges unsent voice notes with her younger brother, Eero, who believes she chose the Moon over their family. Her present problem is a repeating burst of interference from a supposedly dormant lunar relay: it resembles a human voice, but the timing is too regular to be an ordinary distress call.
