All My Summons Become Divine Girls

Chapter 519: Three Hearts, One Failing Body

The alarm carried no sound, because the engine had never needed one before.

Every civic slate in the freed districts lit at once with the same three-line reading, and the reading did not agree with itself.

The north heart ran hot, the river heart ran slow and heavy, while the sky heart skipped every fourth beat.

"They are not failing together," Aria said, laying the three rhythms across Hajin’s sight as the stair cleared. "They are failing separately, on three different schedules, toward three different disasters."

The war table had assembled itself in the engine’s outer hall by the time he arrived. A city that had spent one day learning to disagree could still agree on an emergency.

Warden Ilyra brought the engine ledgers, Oren brought weather readings older than his own hands, and Sava brought ink-stained maps with no tremor at all.

Fear had a strict hierarchy, and this emergency outranked it.

"The north heart feeds the shield over the foundry quarter," Oren said, tapping the first map. "When it runs hot, the shield there thickens until the air goes stale."

"The river heart drives the canal locks plus the water shares," Sava added, tracing the blue lines with one steady finger. "Running slow, it starves three districts of water before noon, and the outer camps by evening."

The map under her hand showed every street the expedition had fed through the bread line, waiting on a failing pump.

"The sky heart keeps the upper terraces breathing," Ilyra said, setting the last map down flat. "Every skipped beat drops the terrace pressure, and four hundred people live up there."

Three hearts, three neighborhoods, three clocks that no longer told the same time.

The freed districts read the slates in their own kitchens, and the city that had just learned to argue learned a colder fact about engines.

Plain disagreement between neighbors was survivable, the whole city learned. Inside the machine keeping the sky up, disagreement was a countdown.

[ ShadowMage44: ] the engine has three hearts and all three are dying separately, bro

[ NewViewer_02: ] so who fixes it? who can even reach all three at once?

Ferra arrived with her leather belt full of merged sketches, and the three uninterrupted days she had asked for were visible in her eyes as three entirely interrupted ones.

"I finished the grammar merge anyway," Ferra said, spreading the Watcher’s angular notation across her own charcoal loops until the two systems locked together like a key meeting its lock.

"This is the original custodian protocol, the whole architecture, plus it tells us exactly how bad this is."

"Tell us the bad part," Hajin said.

"The custodian protocol was built for a distributed custodian," she said, tracing the old orbit lines across the merged map. "The engine expects one will, present at every heart, holding all three rhythms at once."

"The nodes were a bridge once, walked by people who went home at the end of their shifts. One intention, many stations, and that arrangement is what maintained the balance."

"And the protocol says what happens when the intention is one man?" Juna asked from the door, arms crossed, wearing the new terms like armor.

"It says the intention must be present," Ferra said, looking up from the map. "Not informed, not updated, but present and live at each heart, on each heart’s own schedule."

Aria ran the routes before anyone asked her to, and the projection told the truth in cold white lines.

"The north heart requires a hold every forty seconds, the river heart every ninety, plus the sky heart every sixty. Travel between any two hearts takes no less than two minutes at Ring speed."

"Therefore one fighter maintaining live contact with all three hearts is impossible by every route plus every ordinary communication."

The projection hung the sentence in the air like a verdict.

The table went quiet while the arithmetic settled over it.

One man, present at three places, on schedules that overlapped like badly shuffled cards.

[ LurkerNoMore: ] the math is just flat impossible. forty second windows two minutes apart in three directions

[ CringeSlayer91: ] unless the man is not one man. and we all know where this is going

Hajin looked at the three rhythms for a long moment, and the wound from the school street opened its one eye.

"I can Phase Lock one heart’s frequency and stabilize it," he said slowly. "One only, while the other two keep failing behind me."

"Then we rotate you," Ilyra said. "Stabilize north, run to river, run to sky."

"The rhythm slips within thirty seconds of my leaving," he said, having already run the numbers in his head. "Rotation saves one heart and loses two, forever."

"Volunteers?" Oren asked, looking around the whole table for one raised hand.

"The protocol needs presence, but perhaps presence can be taught."

Ferra shook her head slowly over the merged grammar sheets.

"The protocol rejects it," Ferra said flatly. "The engine reads the holder’s will like a signature, and every failed handover in the record cracked the heart a little further."

She rolled the merged sketches closed again with terrible care.

"This engine has been cracked enough."

Vella arrived last, still in her treatment wrap, with sixty-three unrecovered citizens sleeping behind her.

"I have people whose minds are held together by my continuing presence," she said quietly. "So I understand exactly what this engine is asking, and I refuse to pretend it is reasonable."

"Nobody at this table thinks it is reasonable," Hajin said.

"Good," she said, setting one gold-warm hand flat on the merged map. "Then say the unreasonable thing out loud, so we can all stop circling it."

The hall waited, the chat waited, plus thirty-six skies waited with them.

"The engine needs one will at three hearts," Hajin said. "So the will has to learn how to be in three places."

"Ring division," Eirwen said from the doorway, roots already awake under the flagstones. "The thing your line practiced before the war made it a crime."

"The thing I have been circling since the mountain."

He looked at Juna then, honoring the terms before the first Ring, and gave her the count out loud.

"Six Rings, one anchor each, a technique nobody living has validated, plus a real chance of cooking my own pathways."

"Then this is me finding one different road," Juna said, stepping to the table to look at the impossible three-clock map.

She stood over it for a long breath, and her shoulders dropped.

"I cannot find one, because there is no other road anywhere on this table."

"The engine needs three of you, and I cannot be three of you."

"So I get the next thing," she said, her hand finding his wrist over the Ring light. "The count is witnessed, the risk is written, and when you come back from wherever this technique takes you, you come back all the way."

"Witnessed," he said, and the word mattered more than the arithmetic.

Under the hall, the north heart ran thirty seconds hot, the river heart slipped another degree, and the sky heart skipped its beat.

The engine did not care that its only candidate repairman was one exhausted man with a family to answer to, on thirty-six days of remaining sky.

The problem had become structural, and structures do not care how tired one man is.

Somewhere in the expedition camp, a five-year-old boy was already asking the Watcher about the old records.

Children hear everything, and the next door of this arc had started opening on its own.
