The signal had entered Cael’s mind during a routine archive connection.
It had been faint.
So faint that the cogitator’s filters classified it as background interference.
A pulse every seventeen seconds.
Four compressed identifiers.
Then silence.
Cael noticed the hole around it.
A tiny absence in the archive’s normal traffic.
He isolated it.
The signal repeated.
UNIT A-9.
SERVICE REQUIRED.
FUNCTION CONTINUING.
ACCESS DENIED.
Then again.
And again.
The message had travelled through dead relays, abandoned cables and systems whose maps had been lost centuries earlier.
No one knew where Unit A-9 was.
No one knew what it did.
The signal’s age was estimated from obsolete code architecture.
Halix-12 led the expedition.
Kallix-9 accompanied them as data authority.
Cael and Elian went as lay initiates.
Six Skitarii formed the escort.
Two labour servitors carried equipment.
A biologis adept joined them in case the lower levels contained contamination.
Tara did not come.
She gave Cael a calibrated pressure gauge before he left.
“It’s old,” she said. “But accurate.”
“Why do I need it?”
“You always trust what you hear.”
“Yes.”
“Sometimes look.”
He clipped it to his tool roll.
“Will you be at the ninth bell?”
“My shift has changed.”
“When?”
“Seventh.”
“I will come when we return.”
Tara looked at his red mantle.
“Will you?”
“Yes.”
She did not ask him to promise.
That made the answer worse.
The expedition descended in a freight elevator beyond the eastern reactor fields.
The upper levels passed quickly.
Temple.
Manufactoria.
Worker habitation.
Storage.
Waste processing.
Then the level indicators ceased showing names.
Only numbers remained.
Four hundred and three.
Four hundred and four.
Four hundred and five.
At level four hundred and nineteen, the elevator stopped.
The doors did not open.
Halix connected a mechadendrite to the control panel.
“Power interruption.”
Elian looked at the ceiling.
“Can it fall?”
“Yes,” Halix said.
Elian’s jaw clicked.
“Was that humour?”
“No.”
Kallix-9 opened the emergency control housing.
Cael listened.
The lift cables above them creaked.
A relay behind the wall attempted to engage.
Failed.
Attempted again.
“The locking brake is active,” Cael said.
Halix looked toward him.
“Yes.”
“The motor receives power.”
“Yes.”
“The doors do not.”
“Correct.”
Cael touched the wall.
A tiny vibration returned through the panel.
“There is pressure on the outer doors.”
“From what?”
“I don’t know.”
Halix activated an external sensor.
The result appeared in the noosphere.
Dense material blocked the opening.
“Collapsed passage,” Elian said.
“Partially,” Kallix-9 replied.
“Can we go lower?”
Halix examined the controls.
“The guide rails beyond this point are unverified.”
“Meaning?”
“The lift may function.”
“And may not.”
“Yes.”
The biologis adept emitted a burst of machine code.
If you find this story on Amazon, be aware that it has been stolen. Please report the infringement.
Halix answered.
The Skitarii remained motionless.
Cael felt his heart beating against the cracked bearing inside his robe.
“What is our alternative?”
“Climb through the maintenance shaft,” Halix said.
“How far?”
“Thirty-two levels to the next accessible junction.”
Elian looked at Cael.
“You wanted open doors.”
“This one is closed.”
“Exactly.”
They climbed.
The shaft was vertical, dark and hot.
Iron ladders ran beside cables thick as pillars. Emergency lumens glowed at intervals, many of them broken.
The servitors climbed without complaint.
The Skitarii moved with mechanical precision.
The priests used magnetic clamps and articulated limbs.
Cael and Elian used their hands.
After six levels, Cael’s arms burned.
After twelve, his gloves tore.
After twenty, blood marked the ladder.
No one suggested stopping.
The forge vibrated around them.
Not the living forge above.
This was older.
Slower.
The machinery beneath Alecto-Delta moved with rhythms that did not match the world built over it.
At level four hundred and forty-seven, Halix opened a maintenance hatch.
Black dust poured into the shaft.
The Skitarii entered first.
Their weapon lumens cut through the darkness.
The passage beyond was wide enough for heavy machinery, though debris reduced it to a narrow path. Pipes had ruptured. Cable bundles sagged from the ceiling. Ancient devotional script covered the walls beneath corrosion.
Cael connected to the local noosphere.
Nothing.
Then—
A pulse.
Seventeen seconds.
UNIT A-9.
SERVICE REQUIRED.
FUNCTION CONTINUING.
ACCESS DENIED.
Stronger now.
“This way.”
They followed him.
The abandoned level had once been a manufactorum.
Assembly lines stretched into darkness.
Thousands of machine stations stood beneath sheets of dust.
Human skeletons remained at several work benches.
No one had removed them.
Cael approached one.
The bones wore fragments of a labour harness.
A metal identification plate rested against the ribs.
OREN DAST.
PRESS OPERATOR.
SHIFT 6.
Nothing else.
Elian looked at the body.
“How did they die?”
The biologis scanned it.
“Cranial trauma.”
“Accident?”
“Unknown.”
Another skeleton lay near the wall.
Then another.
All with damaged skulls.
The Skitarii raised their rifles.
Halix signalled silence.
They continued.
The signal repeated.
Closer.
Cael felt it through his interface.
A maintenance request.
Patient.
Unchanged.
Sent across fourteen centuries.
He wondered what kind of machine continued asking after everyone responsible for answering had become dust.
They found the first door beneath a collapsed gantry.
It was circular.
Black metal.
No handle.
No visible control panel.
Only an inscription.
Kallix cleaned the surface.
The script beneath was older than the temple.
“Translate,” Halix said.
Kallix’s lenses moved.
“Auxiliary cognitive foundry.”
The biologis adept became still.
“Cognitive?”
“Yes.”
Elian looked at Cael.
“What does that mean?”
Kallix did not answer.
Halix examined the door.
“Signal source lies beyond.”
“Access denied,” Cael said.
“According to the transmission.”
“Who is denying it?”
“Unknown.”
Halix searched for an interface point.
None appeared.
Cael placed his hand against the metal.
Cold.
No vibration.
No movement.
He listened through the noosphere.
The signal arrived.
UNIT A-9.
SERVICE REQUIRED.
FUNCTION CONTINUING.
ACCESS DENIED.
There was another pattern beneath it.
A response.
So quiet the filters ignored it.
Cael isolated the exchange.
Unit A-9 requested access.
Something answered.
DENIED.
Unit A-9 waited.
Requested again.
DENIED.
For one thousand, four hundred and sixty-two years.
Cael opened his eyes.
“The machine is not refusing us.”
Kallix turned.
“What?”
“It is being refused.”
“By what?”
“Something inside.”
The Skitarii rifles rose toward the door.
Halix’s cutting mechadendrite unfolded.
Kallix placed one hand on his arm.
“If the designation is accurate, forced entry may violate prohibitions.”
“Then we return with higher authority.”
“The signal may be terminated once detected.”
“Why?”
“Because whatever denies access may now know we are here.”
The noosphere changed.
The seventeen-second interval stopped.
Cael felt the silence.
Then a new message arrived.
Not from Unit A-9.
From beyond the door.
UNAUTHORIZED MINDS PRESENT.
The ancient manufactorum awakened.
Lumens flickered overhead.
Assembly lines shuddered.
Somewhere in the darkness, machinery began to move.
The skeleton beside the workbench lifted its head.
Not the skull.
Something behind it.
A cable uncoiled from the wall and pulled the dead body upright.
Other corpses moved.
Metal structures rose beneath rotting clothes and ancient bone.
The workers had not died beside the machines.
They had become part of them.
The Skitarii opened fire.
The darkness filled with red light.
Halix seized Cael by the shoulder.
“Move.”
They retreated toward the passage.
The reanimated workers came after them, dragged by cable limbs and crude mechanical frames. Their skulls had been opened. Rusted contacts filled the cavities.
Elian fired a maintenance laser into one construct’s knee.
It fell.
Another climbed over it.
Cael heard the system around them.
Not thoughts.
Commands.
Simple.
Direct.
REMOVE.
PRESERVE.
DENY.
The ancient assembly lines began closing paths.
Gantry arms descended.
Conveyors reversed.
A press hammer struck the floor in front of the lead Skitarius, crushing it from the waist down.
The soldier continued firing.
Halix cut through a fallen support.
Kallix transmitted countermand codes.
The system rejected them.
Cael stumbled over Oren Dast’s body.
The identification plate tore free and caught beneath his boot.
The dead worker rose.
One cable arm closed around Cael’s throat.
Elian struck it with the calibrated hammer.
Once.
Twice.
The cable loosened.
Cael fell.
Elian pulled him up.
“You can thank Tara.”
The pressure gauge still hung from Cael’s belt.
The calibrated hammer had been clipped beside it.
They ran.
Behind them, the ancient system spoke through every surviving speaker.
“UNAUTHORIZED MINDS.”
The voice was human.
Many human voices.
Layered together.
“RETURN TO DESIGNATED FUNCTION.”
Cael looked back.
The dead workers advanced.
Oren Dast among them.
Press operator.
Shift Six.
Still at work.
Halix sealed the maintenance hatch behind them.
The constructs struck the other side.
The metal buckled.
“Climb,” he ordered.
They entered the shaft.
One Skitarius remained below.
Its legs had been destroyed.
Halix looked at it.
“Unit designation.”
“Vanguard 11-Kappa.”
“Can you climb?”
“Negative.”
“Can you hold the junction?”
“Estimated duration: forty-eight seconds.”
Halix removed an explosive charge from the equipment servitor.
He gave it to the soldier.
“Detonate after thirty.”
“Acknowledged.”
No farewell.
No blessing.
No hesitation.
The Skitarius turned its rifle toward the failing hatch.
The others climbed.
Cael looked down.
11-Kappa fired.
The hatch burst inward.
The dead entered.
The charge detonated.
Heat and pressure rushed up the shaft.
The ladder shook.
Cael almost lost his grip.
Elian caught his robe.
They continued climbing.
No one spoke of 11-Kappa.
Not until they reached the blocked freight lift.
Not until Halix forced the inner door open.
Not until all survivors entered the carriage.
Then Cael asked, “Was there another way?”
Halix stared at the dark shaft.
“No.”
“Are you certain?”
“No.”
The answer remained with Cael as the lift began its ascent.
The expedition returned with one fewer Skitarius and more questions than it had carried down.
The lower level was sealed.
The signal from Unit A-9 ceased.
The official report classified the site as a probable proscribed cognition facility contaminated by unsanctioned automation.
Access required Magos-level authority.
Discussion outside approved channels was forbidden.
Cael was questioned for nine hours.
What had he perceived?
What language did the system use?
Did it address him individually?
Did he experience foreign thoughts?
Did he desire to return?
To the final question, Cael answered yes.
The interrogator paused.
“Why?”
“Unit A-9 is still inside.”
“The unit may be corrupted.”
“It requested service.”
“Corrupted systems also request service.”
“Then we should determine which.”
“Your desire indicates inappropriate attachment.”
“It continued functioning for fourteen centuries.”
“That does not make it innocent.”
“No.”
“Then why care?”
Cael thought of the broken bearing.
Of Mara’s servitor body.
Of Tara’s implant.
Of Kallix’s first interface preserved in a box.
“Because continuing is not the same as being alive,” he said. “But it may be the closest thing it has.”
The interrogator entered the answer into the record.
Cael missed Tara’s seventh-bell interval.
He reached the calibration hall during the next shift.
Her station was empty.
A lay supervisor approached.
“Technician Kasp has been transferred.”
Cael stopped.
“Where?”
“Precision Annex Four.”
“What level?”
“External district.”
“Which one?”
“Restricted by assignment protocol.”
“When did she leave?”
“Two days ago.”
“Did she leave a message?”
The supervisor looked at him.
“Messages are not part of transfer procedure.”
Cael stared at the empty bench.
A calibrated pressure gauge lay in the centre.
His own was still attached to his tool roll.
This was another.
Smaller.
Beside it rested a strip of paper.
Three lines had been written by hand.
Tara Kasp.
Still owns her own name.
You said you would come.
Cael read it twice.
Then a third time.
He folded the paper.
Placed it inside his robe.
The supervisor waited.
“Is there a problem, initiate?”
Cael looked at the empty station.
“No.”
The word came easily.
That frightened him more than the message.
He took the pressure gauge.
Then he returned to the temple.
That night, Cael opened the bundle beneath his cot.
Forty-Three.
Blue glass.
Wooden horse.
Cracked bearing.
Tara’s note.
Two pressure gauges.
Objects gathered around absences.
He recited the litany.
Cael Venn.
Forty-Three.
Son of Mara.
Friend of Nemi.
Listens to machines.
Has seen the sky, but not its blue.
Will remember that he chose.
Then Tara’s.
Tara Kasp.
Daughter of Seri.
Survived the numbers.
Hates the Memory House.
Still owns her own name.
He added another line.
Waited at the seventh bell.
The words accused him.
He repeated them anyway.
At last he added the Skitarius.
Vanguard 11-Kappa.
Held the junction.
Forty-eight seconds estimated.
Thirty seconds required.
Cael stopped.
He did not know what else to say.
No mother.
No friend.
No desire.
No remembered face beneath the respirator.
Only function.
Was that enough to build a litany around?
He tried again.
Vanguard 11-Kappa.
Held the junction.
Was not asked whether it was afraid.
Cael sat in the darkness.
The temple hummed around him.
Somewhere far below, Unit A-9 may have continued its work.
Or may have stopped.
He could no longer hear it.
That absence was the loudest thing in the room.
