By evening, Oven could speak only in a whisper.
He led Marek and Saya to a field stove beyond the outer ring. The post was officially listed as empty, but six garrison shifts stood watch nearby. Their operators had heard Oven refuse to detain Marek and had seen the record of the silencer test.
That did not make them allies. One operator demanded that all direct sparks remain beyond the salt line. Another asked what would happen if Irsa tried to draw the network towards someone else's face again. A third wanted to know whether Marek could shut down their stoves whenever he disliked the garrison's decision.
Marek answered them in turn. He could not guarantee that Irsa would never make another mistake. Direct sparks would not enter the post without separate permission. And he still had the power to suppress local nodes through the anchor. Nobody liked the last answer, Marek included.
Marek did not ask an operator to open the stove for a new form. First he sat beside the cold casing and spoke to the voice beneath his collarbone.
"I won't force you to take Ella's shape again," he said. "I won't use you as a vessel for her memory."
Irsa did not answer at once.
"Not a vessel."
Marek thought she was agreeing with him, but the cold beneath his skin sharpened.
"You're still talking about me as though I'm a tool," Irsa continued.
It was her second complete sentence. It came slowly: between the words were other people's breaths, fragments of knocking and the rustle of ash. But the meaning belonged to her.
Marek wanted to say he did not know any other way. Saya stopped him.
"You gave her a kind name, but you still make decisions for her," Saya said. "Accept her refusal first. Then we'll know whether you recognise her as a person in her own right."
Marek had named the cold spark Irsa himself when he was sixteen. On the day of the trial she lay in a bowl of ash. Just before the fire went out, the ash made a dry sound: a short "ir" followed by a quiet hiss. The examiner had already written "zero residue", and Marek gave the useless form a name so that at least he would not have to call her defective.
He had never asked whether she wanted that name.
"I can let that go too," Marek said.
One free shell remained in the field stove, and it belonged to the local node. Marek opened a direct line but gave no command. The red form rose above the casing and waited.
Marek removed from the anchor the last order holding Ella's rhythm in place. The five familiar knocks passed through his chest and vanished. With them, the connection that had once allowed him to suppress any local node through Irsa weakened.
"What do you want?" he asked.
The cold echo entered the free shell. The spark took neither a face, a tool nor the outline of a beast. She remained a small red-grey flame, but now there was no command from Marek in her movement.
A wounded signaller lay at the edge of the post. Standing orders said to hide the ledgers first and help people afterwards. Marek gave Irsa no new task. Irsa flew to the signaller of her own accord, caught the fastening that had come undone on his bandage and summoned Saya with a short knock. The act did not strengthen the network or advance the negotiations. Irsa chose it because the man was losing blood.
"Irsa," she said.
Marek heard the same name, but for the first time it did not belong to him.
"And one more thing," Irsa continued. "Don't hold more than twelve other people's wishes inside you."
"That's the limit."
"It's a request."
The limit protected Marek himself: if he broke it, he would lose who he was. Irsa's request could be ignored. That was precisely why his answer would show whether Marek considered Irsa independent.
The garrison immediately tested what had changed. One operator opened a local node and sent a seam to a cracked water pipe. At the garrison's request, Marek ordered every form at the post to stop. Before, Irsa would have carried such an order through the anchor and halted the local lines.
Now only her new shell went still.
The seam continued working until the operator who had assigned it saw Marek's command and closed the task himself. Marek kept his voice and twelve direct lines, but lost the power to suppress other people's nodes with a single movement. The old control could be restored only by binding Irsa to another person's memory again. She had already refused.
The operator recorded the result beside his key: the Shepherd cannot stop another person's node without its operator's decision. If a local person makes a mistake, other witnesses will correct it, not Marek's hidden power.
For the second test, one of the garrison operators relayed an order to his stove to detain the living ash until the Guard arrived. The order came over Rador's official line and appeared lawful.
Irsa touched the signal but did not carry it further.
"Someone else's wish," she said.
Saya checked the order with her thread. It contained neither the local operator's voice nor his voluntary decision. The official frequency was trying to subject the node to the Chamber without the consent of the person at the stove.
The operator burned the line of the order himself and opened the field stove.
For the key, he gave the memory of his first night watch, when he had chosen not to close the gates on a late shift. While the node was working, the operator remembered the people but could not feel the certainty with which he had broken the timetable that night. The right to cut the connection therefore went to a second person who was not bound to his key.
Five more shifts did the same. Each named its key, recorded the possible loss and installed a physical salt cut-off. Together with the three stoves in the Soot, the network now had nine stoves and nine local operators. Their combined physical ceiling was one thousand and eighty sparks.
One gave the memory of a comrade's hand he had held above a precipice. Another gave the sound of the upper shutter opening for the first time. The rest chose simpler memories so they could recount them three times without alteration. Saya rejected two keys: fear had already become mixed with someone else's voice in the first, and the second volunteer consented only because his commander was standing beside him. The stoves were opened after both had been replaced.
As a former captain, Oven inspected the cut-offs, and as a conductor, Saya confirmed that every decision was voluntary. Marek stood behind the white line and touched none of the casings. Only after both inspections did the garrison remove the Chamber's official locks from the stoves.
Marek could still hold only twelve lines directly.
Three white lights flared on the outer tower.
A memory storm was approaching the city, filling all the space between the two salt fields. To release it outside, the Ring's upper shutter would have to be opened and then closed before the cloud's first strike.
A works train was approaching Tarvel along the same route.
It carried the shifts that repaired the Ring from outside after every storm. Those people knew the barrier better than most Keepers, but had no right to open the shutter from their cab. The train had been dispatched before the warning, and the recall order could no longer catch it across the dead stretch of communications.
There were two hundred and three people in the carriages.
Rador ordered the shutter closed before they arrived.
