The first to obey the false voice were not Marek's direct sparks, but three local nodes.
Their operators heard the order through the heat of their stoves, just as they heard Marek's real words. The voice named the correct streets, knew the number of forms and repeated the recent command to strike the Bell. Unlike the living Marek, the imitation left no room for argument.
Three hundred and seventy sparks abandoned the evacuation. Seams left the steam pipe, mirrors deserted the salt frames, carriers lowered their empty stretchers and moved towards the central branch line. Along the way, they were joined by forms left without keys after the night's strikes.
Marek transmitted a cancellation over the twelve direct lines. His sparks stopped. The rest of the network heard two identical voices, but the service frequency made the false order louder.
"That isn't me," Marek kept repeating.
To the stoves, the phrase was simply another command from the same man.
Saya asked the operators not to choose between the voices. Each of them had to check the order against their own memory key and local task. Dara held her forms at once: her street had voted for hospital steam, not a march on the Bell. Two other operators closed their cut-offs.
The third refused.
"If the Bell remains, they'll erase us anyway," he relayed. "At least the first voice promises to end it now."
Marek could not call the man a traitor. He had chosen a comprehensible risk over a slow evacuation and done exactly what the upper circle had done in the Chamber hall.
Hundreds of forms reached the central branch line and struck the Guard's barricade. They did not try to kill. Seams took the shields apart, holders lifted rail plates, and forgemen heated the salt barriers. But the soldiers saw a single advancing mass and answered with white charges.
The front ranks crumbled.
Oven reached the Bell's inner post with five former subordinates. Two notes mingled on the copper plate at his throat: the old recording from the carriage and the current service order. For the silencers to find the imitation, Saya needed a clean sample of the second frequency.
The plate could not be removed again without consequences. Since his confession in the memory hall, only its thin copper edge had kept the burn from reopening. If he tore it away, Oven's voice would go with the metal.
He asked the five guards whether they could open the upper shutter without his commands.
The senior duty officer repeated the sequence: two keys, the manual counterweight, a check of the outer corridor. Oven corrected only one step. Then he removed the plate.
Blood welled from the old burn. Oven tried to speak and heard only air.
The guards could have carried him to the treatment hall. Instead, Oven placed the plate in the communication tube and pointed twice towards the upper shutter. The senior duty officer understood. The five continued without their commander.
Saya received the copper rhythm through the silver thread. Marek's false voice had been woven together with the White Bell's frequency and an archival echo pronouncing the verb 'assemble'. A simple cancellation would not work. The service note itself had to be cut out of every local transmission.
Irsa sent eight silencers towards the nodes. They carried no common order, only Oven's sample. Each operator decided independently whether to admit the dark form into the stove.
Five nodes agreed. Two demanded that the people be brought out of their homes first. One did not answer because its operator was already on his way to the Bell with the forms.
At the central barricade, a salt plate covered the pipe through which Saya could transmit the sample to the advancing swarm. Ordinary heat spread uselessly across the white surface. A forgeman could break through it, but the strike would require three sparks and all the accumulated heat of one local node to be burned.
The operator was the same plumber who had trembled over the key that morning. His stove served two houses and a backup water line. If they gave up the node, the street would have no protection from the next strike.
Marek did not give the order.
The plumber asked his neighbours. The answer did not come at once. One family objected because their sick father lay in the basement. The deputy proposed moving him to Dara's stove. Only then did the street agree to burn its node.
Three forgemen entered the salt plate. The first left a dark mark in it, the second opened a crack, and the third turned it into a passage. All three died, and with them vanished the memory key to the plumber's first pay packet.
The plumber remembered where he had worked, but not the day he first brought money home. His neighbours recorded the loss before sending Oven's sample through the pipe.
The silencers found the false frequency. Part of the swarm stopped at the very shields. Seams released the metal plates they had seized, carriers set down the guards they had lifted, and mirrors extinguished the false passages.
But not all the forms returned.
Two nodes retained the order to go to the Bell. Their operators had decided that even an imitation led to the right objective. Marek could cut them off from the common map, but he could not forbid their choice without becoming the very centre he opposed.
Then Rador activated the rain towers.
Valves opened above the inner streets. Cold water mixed with white dust and settled over the rails in a heavy slurry. The ash forms swelled, lost their edges and were pressed to the ground. The carriers at the evacuation train could not lift the last group of patients.
Beran applied power, but the wheels spun on the wet rail. The leading carriage came out of shelter and stopped in the open corridor between two salt frames. The water had already blocked the way back.
The hospital steam failed inside. The stoker and three passengers took their places at the hand pump, but the carriage pipe was not designed for a long halt. The child for whom Dara had given up the bread ovens' heat began to turn blue around the lips again.
Yuna could not take the people outside: the white frames on both sides read each of them as a bearer of the order. The girl lit five red flashes in the leading window. Marek answered with a sixth through the free listener, but could not move the train.
Then the repair shift supervisor diverted some of the rail seams beneath the wheels. Her node could still hear the false summons to the Bell. The woman blocked the stove opening with her own body and gave each form one task at a time, naming the carriage number and the specific wheel. The seams could not assemble a common route and so did not leave to follow the imitation.
They spread dry mineral ash beneath the wheels. It was not enough to get the train moving, but the carriage stopped sliding towards the salt frame. The people inside gained a few minutes.
Rador offered to open the frame if the train disconnected from the network and submitted to a memory inspection. The passengers would have to be brought out one by one into the rain for the inspection. Yuna asked whether the Chamber would preserve their names after extraction. The reply came as a formula: "Identity will be restored within the bounds of public necessity."
No one came out.
Commands from the streets, Saya's cancellation, Marek's false voice and the Guard's emergency order to close the shutters all entered the network at once.
Irsa repeated them all.
Her small shell split into several mouths. One asked for the swarm to assemble at the Bell, another to send the carriers back to the train, and a third to carry out the archived wishes. The surviving nodes answered different words and pulled her in different directions.
Marek tried to remind Irsa of the name she had chosen. In reply she called herself Dara's voice, then Rador's, and finally his own. Every order left in her the person it belonged to, while the service frequency compressed them into a single wish.
The dark silencers circled nearby, but could not cut out all the notes at once. To cleanse Irsa, they would have to decide which voice did not belong. Neither Marek nor Saya had the right to choose for her.
"Destroy me," Irsa said to Marek in her own voice. "While I still know who's asking."
