It began by isolating a voice on 462.5625 MHz — a municipal frequency that usually carried logistics: water main repairs, garbage pickups, a grit of daily trivialities. The voice was oddly sepia-toned, not just in content but in cadence, like someone reading a weathered letter aloud. The de-interleaver reconstructed overlapping digital frames, smoothing them into human speech. A name surfaced: "Marta." Then a place: "North Bridge." Arthur frowned.

It had once been a tool he used nightly, tuning into nearby police dispatches and the quieter, private conversations of neighborhood amateurs. He’d learned to read the cadence of a voice before the squared waveform turned into words.

The next morning, someone on the forum posted a link to a small zine printed in a coastal town's bookstore, a collection of short stories compiled by volunteers called "The Keepers' Lantern." The zine's fourth story, written under the name NovaEcho, told in careful, folded prose how a ferry operator once lit the way for lovers and fishermen, and how people learned to send each other hope by the cheap rhetoric of radio.
