Kest waited until we were halfway back to the Custodial Office before starting the argument.
“You are not sending me through the bypass.”
“That is correct.”
“I did not ask.”
“That is also correct.”
Greymarrow’s living stone carried my words again now that we were clear of the Guild infill.
Kest stopped.
“The passage fits me. You do not. The main entrance reports a breach. So the bypass is the only route we found behind the seal.”
“Yes.”
“You asked Greymarrow whether it wanted the line cut.”
“Yes.”
“You asked Nera whether she chose to help.”
I already disliked where this was going.
“Kest—”
“You do not get to stop asking when the answer might scare you.”
That landed harder than I preferred.
The white collection mark still crossed her damaged wing.
A classification I had once made. A professional conclusion about what counted as protected life, reached without asking the person who lived there.
“I am not classifying you as incapable.”
“No. You looked at the passage, looked at my wing, and decided.”
“I decided sending you alone beneath Orren Hale’s team with a collection beacon active nearby was a bad plan.”
“That is not the same as asking me.”
No.
It was not.
Concern could become authority very easily when the concerned person trusted his own judgment more than somebody else’s choice.
Kest stepped closer.
“You told Nera the risks. You told Greymarrow. Tell me.”
I closed my lid.
Then opened it.
“The bypass may be narrow enough to catch your brace. We do not know if it is structurally sound. Greymarrow’s living stone does not extend through most of it, so I cannot speak to you once you cross.”
She listened.
“There is one active collection beacon above and east of the pressure gallery. Signal Recognition gives me approximate distance and direction. It does not tell me what the beacon is attached to or what it is configured to track.”
“And the far end?”
“Unknown. We do not know whether it reaches the Source Service Spine, or what waits there.”
“And?”
“If something goes wrong, I cannot follow you.”
There.
The part I disliked most.
Kest looked toward the dark passage.
“Anything else?”
“Yes. I do not want you to go.”
For a moment, neither of us moved.
Then she nodded.
“That one is yours.”
Annoying creature.
“Yes.”
“My choice is still mine.”
Also yes.
“I want to inspect it.”
Not fight.
Not charge through.
Inspect.
“What conditions?”
Her beak tilted.
“You are asking now.”
“I remain teachable.”
“No fighting. If I see a worker, I return. If the passage gets tighter than my brace can clear without forcing it, I return.”
“If the beacon moves toward you, return.”
“Yes.”
“If you find LS-1, observe only. Touch nothing connected to the trunk.”
“Agreed.”
We returned to the Custodial Office.
Nera rested against Marda. Pebble had tucked cloth beneath Nera’s numb left hand. Rill had expanded his black spiral across the dust. Tallow sat beside the empty preservation frame, his brass brace visible.
I explained the sealed access, Orren’s team overhead, the collection beacon, and the bypass.
Nera looked at Kest.
“Do you want to go?”
“Yes.”
“Do you understand the overflow may have shifted, you may not have room to turn, and it may end at a grate instead of the service spine?”
“Yes.”
“And there are people above you.”
“Yes.”
Nera nodded.
“Then plan the return before the entry.”
I stared at her.
“I expected more opposition.”
“I was a Custodian, not a jailer.”
Fair.
Marda lowered her head.
“Small wing goes?”
“Kest chooses to inspect.”
“Come back.”
“I plan to.”
“Plan harder.”
Tallow stood.
“No,” I said.
His flame sharpened.
“You are not fitting through that passage with the leg.”
He pointed at Kest, then himself.
Nera raised her free hand.
“He may still help. The old overflow pipes were copper. If enough remains continuous, use it for sound.”
Useful.
Not speech. Not Greymarrow carrying intent.
Physical taps.
Greymarrow showed us the old copper line running beside the overflow, broken in two places farther down but continuous almost to the tollhouse foundation.
We established four signals:
One tap: clear?
One answering tap: clear.
Two taps: stop and listen.
Three taps: return immediately.
Four taps from Kest: found the far end.
Then a contingency.
If I sent three taps twice in quick succession, Tallow would create noise farther east through the copper line and waterworks fittings.
A distraction only.
No improvising beyond that.
Tallow tok-tokked once.
He wrapped charcoal in a lump of wax and handed it to Kest.
“For labels,” Nera said. “Copy anything you do not understand.”
I approved strongly.
We returned to the waterworks.
Tallow stopped at the last broad section of living stone, where he could reach the copper line and still hear me through Greymarrow.
Kest and I continued to the pressure gallery.
The Continuance seal remained intact.
The active collection beacon sat above and slightly east.
Stationary.
For now.
The bypass entrance was a broken overflow throat barely wider than Kest’s shoulders.
She studied it.
I studied her brace.
“We already had this conversation.”
“Yes.”
“Anything changed?”
“No.”
“Then stop appraising my wing.”
“I cannot promise impossible things.”
Kest lowered herself.
Before entering, she looked back.
“I choose this.”
Not accusation.
Not permission requested.
A statement.
I tapped once against the copper pipe.
Clear?
She answered once.
Clear.
Then she disappeared.
Her tail vanished last.
I hated the passage immediately.
For the first minute, faint scraping traveled through stone. Then even that weakened.
The beacon remained above and east.
One minute.
Two.
I tapped once.
A faint answer returned.
Clear.
Three more minutes passed.
Then the beacon shifted.
Range decreased slightly. Direction moved west, toward the sealed access.
Two taps.
Stop and listen.
No response.
My fibers tightened.
Then two taps came back.
The beacon continued across the tollhouse above us, then shifted east again.
Away.
I tapped once.
One answer.
Clear.
Farther back, Tallow tapped once too.
Apparently anxiety traveled efficiently through plumbing.
Then:
four taps.
Found the far end.
I waited.
A minute.
Two.
I tapped once.
Nothing.
Again.
Nothing.
The beacon had not moved.
Two taps.
Stop and listen.
No answer.
Dead stone gave me no Greymarrow voice. No awareness of Kest.
Only pressure.
Only the copper pipe.
Only every bad possibility professional imagination could produce.
I raised one fiber to send three taps.
Before I struck— four taps.
Then one.
Far end found.
Clear.
Relief fit surprisingly well inside a wooden box.
A minute later, the beacon moved.
Fast.
Toward us.
Three taps.
Return immediately.
Three came back at once.
Acknowledged.
Scraping began inside the bypass.
The beacon continued west toward the pressure gallery.
Footsteps struck the tollhouse foundation.
The signal stopped almost directly above the sealed route.
The seal plate flickered.
REMOTE STATUS QUERY
SEAL STATE: ACTIVE
BREACH: NONE
Someone above had checked it.
The display went dark.
A muffled voice traveled down the old drain.
“…nothing.”
Another answered.
“Again.”
The plate lit.
REMOTE STATUS QUERY
SEAL STATE: ACTIVE
BREACH: NONE
A third voice came clearer.
“Hale said watch the beacon, not just the seal.”
My hinge tightened.
“What moved?”
“Thought I had a range change.”
That told me only that the workers were watching this beacon for range changes.
It still did not tell me what the beacon was configured to track.
Signal Recognition told me where the active beacon was.
Nothing more.
“Probably water,” someone said.
“No water running down there.”
The beacon shifted toward the bypass side.
I sent three taps.
Return.
Scraping answered.
Then a sharp metallic sound traveled through the copper.
Not our code.
Kest had struck something.
The footsteps above stopped.
“What was that?”
Kest stopped moving.
The beacon hovered close.
I struck the pipe.
Three taps.
Pause.
Three taps again.
Emergency return.
Distraction requested.
A heartbeat later, Tallow hammered an irregular burst through the eastern fittings.
Three impacts.
Two.
Five.
Not our code.
Just noise.
Footsteps shifted.
“What was that?”
“East side.”
The beacon moved east.
Away from Kest.
Scraping resumed.
Closer.
Kest’s claws appeared from the overflow throat.
Her head followed.
Shoulders.
The brace caught.
She stopped.
My fibers were already extended.
Do not pull the wing.
I hooked the stone beneath her front claws and gave her leverage.
Kest twisted.
The brace cleared.
She slid out and collapsed beside the wall.
After several seconds she whispered, “That was unpleasant.”
I knocked once.
Yes.
She looked toward the pipe.
“Tallow?”
One knock.
Her beak curved.
We withdrew immediately.
At the living-stone boundary, understandable words returned around my intent.
“Tallow.”
A distant tok-tok answered through Greymarrow.
“You magnificent little nuisance.”
Tallow waited in the wider gallery with his flame standing tall.
Kest touched two claws to his shoulder.
“You saved my tail.”
Tok-tok.
He looked smug.
I permitted it.
Only when we were back in the Custodial Office did Kest show us what she had found.
“The bypass ends behind the sealed opening,” she said. “There is a maintenance recess between the infill and the actual spine.”
“Can it reach LS-1?”
“Not directly. There is a grate. I could see through.”
She scratched her copied notes onto a flat piece of bronze.
LOCAL SEVERANCE STATION LS-1
Then:
SERVICE ACCESS — EXTERIOR WITNESS AUTHORIZATION
Nera leaned closer.
“Witness authorization?”
Kest nodded and wrote:
AUTHORIZED SERVICE OPENING DOES NOT CONSTITUTE BREACH
Very good.
Then:
ALL ACCESS EVENTS RECORDED
Less good.
Finally:
REGISTERED WITNESS TOOL REQUIRED
Nobody spoke.
My attention moved to the wrapped appraisal knife secured outside my rear strap.
Nera followed it.
“No.”
“That is almost certainly a registered witness tool.”
“It is also the knife used to anchor your murder to Greymarrow’s heart.”
“Both can be true.”
Kest tapped the bronze.
“There was a shape beside the instruction.”
She drew it.
A narrow blade. Black grip. Service tang entering a rectangular slot.
Not my knife specifically.
A class of Guild witness tools.
My appraisal knife belonged to that class.
I unwrapped the tang.
Dried blood remained in the recesses.
So did the installation stamp.
PROVOST L. VEYR
OFFICE OF CONTINUANCE
Beneath it sat the old authenticating filament of my appraisal license.
Nera watched me.
“If you use that, the seal may open without reporting a breach.”
“Yes.”
“But the access event will be recorded.”
“Yes.”
“The tool authorization may identify you.”
“Almost certainly.”
Kest looked at the blade.
“They already know Calder’s witness is active.”
“They know the legacy witness has current agency. They know I reached the heart. They do not necessarily know where I am at every moment.”
“And using the knife narrows that.”
“Yes.”
Marda spoke behind Nera.
“Door opens. Hunters learn where box is.”
“Succinct.”
Nera studied the knife.
“Can we confirm it will authenticate before taking it there?”
The Custodial Office could not test Guild service authorization.
But the heart review had recognized the knife. The mendery had recognized its witness filament. After the sixty-second suspension, the Continuance system had restored my survey state through it.
SURVEY STATE: OPEN — UNANCHORED
The knife was no longer in Greymarrow’s heart.
The witness still mattered enough for the network to care.
“What exactly did the slot symbol look like?”
Kest redrew it.
A narrow notch along the lower edge.
I turned the knife tang.
The same notch sat beneath Veyr’s installation stamp.
Not proof.
Strong correspondence.
Nera exhaled.
“They built a service access that an authorized witness tool can open without creating a breach.”
“And my knife is probably still authorized.”
Kest looked between us.
“So we have a way through.”
“Probably.”
“No breaking the seal.”
“Correct.”
“No sending me alone.”
“Correct.”
She seemed pleased with that one.
I was less pleased with the rest.
Someone had murdered me with my own appraisal knife.
Then Continuance had used that same knife, under Veyr’s installation authority, to anchor false authority into Greymarrow’s heart.
Now it might be the cleanest key into the station capable of cutting Continuance away.
The small status strip beneath Nera’s panel flickered.
RECOVERY PROTOCOL — ACTIVE
ESTIMATED ARRIVAL: 29:41:08
Just under thirty hours.
Then:
LOCAL SERVICE ACCESS: MONITORED
Kest read it.
“They changed that?”
“I do not know whether it was already monitored.”
Important distinction.
No accusation appeared.
No access event had been recorded.
Yet.
I wrapped the knife again.
The next move was clear.
We did not need to break Orren Hale’s reinforced wall.
We had a probable key.
Unfortunately, the key was the knife that killed me.
And the moment I used it, the access record would almost certainly carry Calder Voss’s dead witness authorization straight to Continuance.
