One hundred and twenty answers did not mean one hundred and twenty stoves ready to run.
Eleven casings had been shattered by salt. The valves on thirty-seven would not hold, and on another fourteen the workers had not managed to open the old flues. Less than three hours remained before the storm.
Two hundred and three track workers spread out across Beran's map. They did not try to restore every node completely. A single seven-minute cycle required an intact firebox, a draught and two independent cut-offs. Everything else could wait until dawn.
The shift supervisor introduced a simple inspection procedure. A mechanic named the damage, a local resident confirmed that they understood the risk, and the future operator demonstrated how they would stop the stove by hand. If even one answer was missing, the casing was not started.
Marek could not see the common map and followed the repairs by Yuna's red lamps. One long light meant a firebox was ready, two short ones showed that metal was needed, and five flashes called for a witness to a memory key.
The White Bell drowned out voices, but it could not prevent people from looking into one another's windows.
By the beginning of the final hour, one hundred and nine casings had been restored. For the eleven shattered stoves, Beran proposed using carriage fireboxes removed from the stationary trains. That would leave the trains without heat of their own. If the evacuation dragged on, the carriages would grow cold.
Yuna asked the passengers on the first train. The people already stood between the salt frames without steam and could have demanded that the fireboxes be left to them. They agreed to give up eleven. Another two were removed from empty service carriages that the Chamber had reserved for transporting archive fuel.
So the last stoves did not come from some hidden reserve of Marek's. They were assembled from the very parts of the trains on which the residents' own evacuation depended.
Saya could not inspect one hundred and twenty memory keys in person. Her former licence had made her the sole lawful witness, and after the thread was cut even her authority no longer held.
The conductor refused to create a new monopoly. At each stove, a memory was declared before two people: one chosen by the street, the other representing those who might be affected if the node failed. In the hospital quarter the second witness was the stoker; at the bread stoves, the role was taken by the family of a child who had received steam. Both recorded not the entire contents of the memory, but the boundary of consent and the means of stopping the stove.
Dara did not restore her key with an archive copy of the lost morning. She chose a new memory: the moment that day when her neighbours called her a stove-setter again after her loss. The Chamber could erase it, but could no longer claim that her right had come only from her dead mother.
The stoker's mother again refused to give up the memory of her daughter. She became the second witness at three neighbouring stoves and made sure every log contained the line: a human echo is not part of the heat reserve.
Nine of the eleven streets that had refused that morning changed their decision. They did not admit that Marek had been right. The residents had seen that after losing the face he truly could not take someone else's node, and considered that a more reliable guarantee than a promise. Two more streets maintained their refusal even with the storm coming. Their fixed stoves remained dark, and the neighbouring operators undertook not to occupy the empty casings without a new vote.
Two additional carriage fireboxes entered the production circle in their place. The passengers chose operators from among their coupling workers and set the stoves directly on the rails. That kept the number of working producers at one hundred and twenty, but the refusal of two streets did not have to be overturned for the sake of a tidy figure.
At the hospital stove, the stoker named the memory of the first boiler he had managed to put out before it exploded. He chose not a happy day, but a mistake that had taught him when to stop. Both the cost and the reason went into the log: if the key died, the second witness would have to recall not only the skill but also the people that act of stopping had saved.
After the increase to two thousand four hundred forms, three hundred and sixty kilograms of purified ash remained in the stores. Growth from three hundred and eighty to twelve thousand required eleven thousand six hundred and twenty new sparks. After seventeen cycles there would still be enough material for another three hundred and eighty. There was enough heat in the service mechanisms as well, provided none was spent warming the upper halls.
Rador cut off the supply from the upper circle. Dara opened the old accumulators beneath the lower railway. They held the heat of pumps, brakes and stove dampers, gathered before the Soot was closed. Not one human last word went into production.
When the first new key turned in a stove, the choir offered Marek a reward.
The formula came at once through the archive pipes, the white loudspeakers and the surviving direct sparks.
"One Shepherd. Complete memory. Complete control."
If Marek restored the central connection and accepted every human echo as part of a single choir, the one hundred and twenty operators would no longer be needed. The stoves would open simultaneously, and every new form would know the common plan at once. The network would have time to grow before the storm struck.
Along with the formula came five knocks.
Then Ella's voice said, "Marek."
It sounded right. Not like the voice of another girl from the archive, and not like Rador's convenient version. The voice caught on the first vowel because Ella had always rushed to say her brother's name after a long silence.
Marek saw the beginnings of a face. Pale eyes, unevenly cut hair, flour on one cheek. The emptiness was filling not with someone else's features, but with those he had lost.
The choir did not promise to restore the past for nothing. It demanded that he open every vessel in the archive, let the wishes of the dead into Marek and allow Irsa to bind them with a single answer. After that, no one would ever be able to separate Ella's true words from the pieces selected for the reconstruction.
Saya heard only the beginning of the formula. His sister's voice came directly through Marek's personal fire.
"You can order me to refuse," he said.
"No."
"Why?"
"Because then the decision would belong to one voice again."
She reminded him of the words that had begun their argument in the sealed carriage.
"A last word isn't fuel."
Marek heard Ella continue saying his name. A few moments more and the face would be whole. He did not know which part belonged to his sister and which had been chosen only to comfort him.
"Keep the echoes separate," he said.
The choir demanded confirmation of the cost.
Ella's exact minute would be inaccessible for ever. The face could not be restored through the network. Unified control would be closed.
Marek confirmed.
The voice broke off before the final syllable. The pale eyes vanished. Once more, the memory held only an empty window and five knocks that explained nothing.
This time he did not answer at once. First he told Irsa what he was choosing in place of an answer.
"Live, but not to remember her for me."
Irsa divided her own shell into one hundred and twenty cold grains. Each went to a separate stove and retained only two things: the name she had chosen and the ability to stop. Not one grain carried a common order.
Irsa's single body turned transparent. She could no longer stand beside Marek or speak from one place. Before the shell died, Irsa asked him not to put her back together, even after the storm.
Before the first cycle, twelve operators each handed Marek one surviving spark. Each retained the right to recall their form, and the log expressly forbade using them as a common conduit between stoves.
Marek had twelve direct sparks again. Not twelve nodes and not twelve streets, but only twelve forms whose tasks he could name one at a time.
At one hundred and twenty stoves, the operators turned their keys independently. Some began earlier, some waited for the second witness, and the streets that had returned turned their keys last. The seven-minute cycles did not coincide or merge into a common rhythm.
The White Bell tried to issue the command, "Assemble."
One hundred and twenty cut-offs closed at different times. Not one stove repeated its neighbour.
One hundred and twenty separate fires lit above the lower circle.
At that same second, the first bolt of the memory storm tore through the Ring of Silence.
