Late on day 1121, the warning came from a village Iven had never heard of, delivered through a line the village had repaired without telling anyone at First Vent.
Leth stood over the relay’s indicator board with a pencil behind one ear. The eastern mast was secured again, and the bent roof beam had a temporary support under it. On the board, a narrow needle trembled beside a mark labeled South Channel. Every few breaths it moved toward the warning line, paused, and returned.
“The town below us isn’t sending it,” Leth said. “They checked their local station. The signal comes from farther down the watercourse.”
“Can you answer?” Iven asked.
“We tried. They haven’t acknowledged.”
Neri examined the board. “Which line carries the return?”
“This one.” Leth pointed to a brass contact on the lower edge. “It was dead when we repaired the junction during the war. We left it isolated from the three-path comparison wheel, with only this separate receiving needle on the warning board. It carries messages, not control of a fourth machine.”
“Someone brought it back.”
