Chapter 353 Under Blackwood

Kael knew he had overdone it before he put his feet on the floor.

The knowledge arrived without drama. His right calf had tightened during the night until the muscle felt shortened beneath the skin, and the ache along his ribs had settled into something deeper than the sharp complaints of the day before. When he sat upright, his body informed him with admirable clarity that carrying stones through a half-collapsed tunnel while recovering from the Caldera had not been among Anwen’s recommended treatments.

He remained on the edge of the bed long enough for the first stiffness to ease, then reached for the cane.

There was a time when taking it would have felt like surrender.

This morning it felt like avoiding stupidity.

By the time he reached the lower hall, Lily had already placed breakfast at the end of the long table and Edwin had placed three documents beside it, proving that neither injury nor attempted murder of public infrastructure excused Kael from administration.

Edwin looked at the cane first.

Then at Kael.

Then at the way Kael lowered himself into the chair.

"You appear refreshed."

Kael reached for bread. "I am beginning to understand why people eventually attempt to poison their stewards."

"Most lack the discipline to maintain the paperwork afterward." Edwin pushed the first document closer. "The Stonebrook bridge closure has now affected scheduled grain transport from two villages. Perrin’s detour is functioning, but travel time has increased enough that two larger wagons will need overnight staging instead of completing the route in a single day."

Kael chewed while reading.

The numbers were small.

That was how most expensive problems began.

One wagon delayed became two. Two became storage fees. Storage fees became spoiled goods, missed market days, replacement horses, dissatisfied merchants, farmers receiving payment late, and finally someone standing in front of Kael’s desk explaining that a bridge repair had somehow become a problem with winter seed.

He signed the temporary transport authorization Edwin had prepared.

"The Guild?"

"Galahad sent word before sunrise. He intends to meet you at the stone yard."

Kael looked up. "Why?"

"Apparently he has developed an interest in ensuring you do not interpret the phrase field assessment to mean crawling into every hole you discover."

"That sounds less like Galahad and more like Anwen."

"They have discovered cooperation."

"That is dangerous."

Edwin’s mouth moved by the smallest amount. "You continue to say that whenever institutions function without requiring your direct involvement."

Kael returned his attention to the paperwork.

The second page concerned the injured road worker.

No break had been confirmed in the lower leg, though the ankle had been badly sprained and the shin required stitches. The healer expected recovery, provided infection did not complicate the wound.

Kael read that sentence twice.

Recovery.

Not burial.

He set the paper down more carefully than necessary.

Edwin watched but did not comment.

The third document was different.

A short report.

Perrin’s handwriting.

Kael read the first line, then stopped eating.

"No wagons?"

Edwin folded his hands behind his back. "None used the abandoned service road during the night."

Kael continued.

Watchers had remained concealed.

Legitimate traffic continued along the detour.

Three merchant wagons passed after dark.

Two before dawn.

All remained on the marked route.

Nobody entered the old stone yard.

Nobody approached the concealed access.

Nobody appeared near the downstream tunnel entrance.

The hidden network had gone quiet.

Kael lowered the page.

"They know."

Edwin did not agree immediately.

"Possibly."

Kael tapped the paper. "The bridge remains closed. Yesterday that produced six unexplained wagons. We watched the road and suddenly none appear."

"Or whoever uses the route does not move goods every day."

Kael glanced at him.

Edwin gave him the look of a man who had spent years correcting emperors before inheriting a seventeen-year-old prince.

"You have been spending too much time with Iris."

"I will inform her that you consider evidence contagious."

"I consider certainty contagious. Evidence is usually the cure."

Kael folded the report.

He had wanted movement during the night.

Not because he wanted more crime inside Blackwood, but because another wagon would have confirmed the pattern while giving them something to follow.

Instead, the silence created another possibility.

Someone might have seen them at the stone yard.

Someone might have noticed the watchers.

Someone might have realized the road records were being checked.

Or the network might simply have had nothing scheduled.

That was the problem with an enemy who refused to perform on request.

Kael pushed himself upright.

His calf protested.

Edwin noticed.

Kael ignored him before he could speak.

"I am going to Stonebrook."

"Yes."

Kael paused.

That had been too easy.

Edwin picked up the empty breakfast plate. "Mistress Anwen left instructions."

"There it is."

"You may travel. You may walk on stable ground. You may enter the inspected portions of the tunnel provided an engineer clears them first. You may not climb through another collapse, lift debris, use strenuous combat techniques, or decide that being seventeen grants immunity to torn muscle."

Kael stared.

"She was very specific."

"She has begun anticipating me."

"She has known you for some time now."

Kael took the cane.

"Anything else?"

Edwin’s expression became pleasant.

"If you return with fresh stitches, she intends to remove you from field work herself."

Kael believed him.

The old stone yard looked less abandoned in daylight.

Not because anything had changed, but because Kael now knew where to look.

Yesterday he had seen weeds, broken stone, a collapsed shed, and a forgotten retaining wall. This morning he saw wheel tracks beneath flattened grass. He saw the clearing where loaded wagons had stopped. He saw drag marks leading behind the shed. He saw the iron ring set into the concealed stone panel and wondered how many people had stood in the same place while believing the yard empty.

Perrin waited near the entrance road with two mounted Black Dragon escorts positioned far enough away not to crowd the clearing. Tavin stood near the retaining wall with his shield on his back, while Iris crouched twenty feet away studying the ground as if it had personally offended her.

Galahad leaned against one of the old stone blocks.

He held the assessment ledger.

Kael stopped walking.

"No."

Galahad looked at the cane. "Good morning."

"You brought that underground?"

"I brought it to the entrance."

"That is not better."

"It is for me."

Kael looked toward Perrin. "Did you invite him?"

Perrin adjusted a strap on his saddle. "I try not to interfere in religious matters."

Galahad’s expression did not change.

Kael decided not to ask.

The older engineer from the bridge emerged from behind the retaining wall, wiping dirt from both hands. He had spent the first part of the morning examining the concealed panel without opening it fully.

"The access is safe enough to uncover," he told Kael. "The passage immediately behind it is stone-lined and dry. I have not inspected beyond the first turn."

"Does it connect to the tunnel under the bridge?"

"I do not know."

Kael nodded.

That answer had become strangely comforting.

Galahad opened his ledger.

"Before anyone enters, assessment question."

Kael closed his eyes briefly.

Iris remained crouched but turned her head enough to listen.

Galahad continued. "State the objective."

"To determine whether the stone-yard access connects to the tunnel beneath Stonebrook Bridge and document evidence of recent use."

"Secondary objective?"

"Map accessible branches and identify other entrances or transfer points."

"Are you pursuing suspects?"

"No."

"Recovering stolen goods?"

"Not unless leaving them creates immediate danger or the evidence will be lost."

Galahad wrote.

Kael hated the scratching sound.

"Stop conditions?"

Kael looked toward the concealed access.

"Engineer declares the structure unsafe. Bad air. Flooding. Unmapped collapse. Signs of imminent structural failure. Evidence that opening a passage could destabilize the bridge or riverbank. Injury serious enough to compromise withdrawal."

Galahad’s pen paused.

"And hostile contact?"

"If we can withdraw without risking civilians or allowing an immediate threat to escape into Stonebrook, we withdraw and reassess. If someone attacks and blocks withdrawal, we defend ourselves."

Tavin nodded once.

Galahad did not.

"What if you identify the person who cut the bridge?"

Kael considered it.

Yesterday, he would have wanted the answer to be arrest them.

Today he could see the trap inside the question.

"If arresting one person destroys our chance to identify the larger network, I consider whether surveillance is safer. If that person is preparing another act that threatens lives, we arrest them immediately."

"Who decides?"

Kael almost answered I do.

He caught the words before they left him.

"House authority decides matters involving Blackwood security. Guild procedure governs Guild participation. Technical safety belongs to the engineers. Iris controls tracking judgments. Perrin controls surface transport and evacuation. Tavin handles defensive positioning where assigned."

Galahad looked at him.

Kael waited.

"And if those judgments conflict?"

"We stop long enough to identify which authority actually applies."

Galahad wrote again.

Iris rose from the ground.

"I hate to interrupt whatever this is."

"An assessment," Galahad answered.

"I know. I was being polite." She beckoned Kael toward the service road. "Someone came here after us."

The clearing changed immediately.

Kael moved toward her.

Galahad closed the ledger.

Iris pointed beside one of yesterday’s wagon ruts.

At first Kael saw nothing.

Then the shape resolved.

A partial boot print.

Only the outer heel and a shallow impression from the front edge had survived in the firmer ground.

Square nails.

Narrow heel.

The same pattern.

"When?"

Kael crouched.

His calf objected, and he shifted weight onto the cane.

Iris touched the edge of the print without disturbing it.

"After yesterday’s rain stopped. Before the dew settled fully."

"That gives us half the night."

"Yes."

"Direction?"

She pointed toward the road.

"Came from there. Walked into the yard. I lose the track on stone near the retaining wall."

"Left?"

"I found another partial print facing outward."

Perrin approached from behind them.

"So someone checked the yard."

Iris stood.

"Someone wearing the same type of boot as the person who used the tunnel."

Kael looked toward the hidden panel.

"They know."

This time nobody corrected him.

The engineer opened the stone access shortly after.

What had looked like part of the retaining wall was a thick rectangular slab faced with matching masonry and mounted on old iron pivots. The mechanism had nearly seized, but fresh grease darkened one hinge.

Fresh.

Not ancient.

Tavin pulled while the engineer levered carefully beneath the edge.

The slab shifted inward.

Cold air breathed through the gap.

Not foul.

Not stagnant.

Moving air.

Iris raised one hand and let a thin current of Wind move across her fingers.

"Airflow from deeper inside."

The engineer lit a small testing flame near the entrance.

It bent inward.

"Draft."

Kael leaned close enough to see beyond the panel.

Stone steps descended six feet into darkness before turning left.

Unlike the muddy service passage beneath the bridge, this entrance had been kept dry.

The steps had been swept.

That detail disturbed Kael more than the hidden door.

Forgotten tunnels collected dirt.

Used tunnels collected habits.

Galahad remained outside.

"You are not coming?"

Kael looked at him.

"I have Guild people on the surface and no intention of becoming another person you have to rescue underground."

"That is unexpectedly sensible."

"I am putting that in your assessment."

Kael turned away.

The engineer entered first.

Iris followed.

Then Kael.

Tavin came behind him.

Mira waited outside with Galahad to coordinate written records, while Perrin took the mounted team along the surface route. Their plan was simple: as Kael’s group mapped underground, Perrin would move above them whenever possible, using timed knocks and distance estimates to determine where passages ran beneath roads, fields, and old structures.

No magic.

No great revelation.

Just measurement.

Kael found himself appreciating that.

The first passage descended farther than expected.

Not deep enough to feel buried beneath the world, but enough that daylight vanished after the second turn. Old stone walls narrowed around them. The ceiling remained high enough for Tavin to stand without ducking, which immediately separated this route from the cramped drainage tunnel beneath the bridge.

The floor explained why.

Two parallel grooves ran along the center.

Kael lowered his lantern.

"Wheels?"

The engineer knelt.

"Small ones."

Iris crouched beside him.

"Not wagon wheels."

"No. Too narrow."

Tavin looked deeper into the passage. "Handcart."

The engineer nodded.

"Or a rail trolley, though I see no metal rail."

Kael followed one groove with the lantern.

The wear continued around the bend.

Repeated.

Not recent enough to have been made during the current operation alone.

This passage had been built to move things.

"What was this place?"

The engineer ran his fingers along the stone.

"Service works, most likely. Stonebrook’s river improvements are older than the current bridge. Different periods too. Some of this masonry predates the timber structure above."

Kael studied the arch.

Blackwood had existed before him.

That should have been obvious.

Yet inheritance encouraged a particular kind of arrogance. Land entered a ledger under your name and began to feel as if its history had been waiting for you.

These tunnels had carried something before Kael had been born.

Before Augustus had given him Blackwood.

Perhaps before Augustus had ever built his house on the estate.

Someone had simply remembered what everyone else forgot.

They moved another forty yards.

Iris stopped.

"Oil."

Kael smelled it after she spoke.

Lamp oil.

Not strong.

Enough.

A shallow stone niche appeared along the wall. An old iron bracket held a modern lantern.

Extinguished.

Clean glass.

Trimmed wick.

Kael looked at the engineer.

"This wasn’t here for road maintenance."

"No."

Tavin touched nothing.

"Recently used?"

Iris leaned close to the wick, then examined the small soot stain above it.

"Recent. I cannot tell you whether last night or three nights ago."

Kael nodded.

They left it in place.

The passage branched twenty yards later.

One route continued downward.

The other turned east.

The engineer marked the intersection with chalk.

Kael unfolded the rough map Mira had prepared from yesterday’s measurements.

"If the main tunnel under the bridge runs here..."

He traced the river.

Iris looked over his shoulder.

"The east branch should approach it."

"Should."

She smiled faintly.

"You are learning."

They took the east branch.

It narrowed gradually.

Mud appeared along the floor.

Then water.

Kael heard it before the tunnel changed shape.

The quiet movement of drainage.

The walls became familiar.

Older brackets.

Low channel on the side.

Roots through mortar.

When they reached a timber brace fitted between stone pillars, Kael stopped.

Fresh oak.

Pale tool marks.

The same place they had reached from beneath the bridge.

They had connected the two entrances.

Stone yard to river tunnel.

Confirmed.

Tavin looked back the way they had come.

"So the wagons stop above. Goods come down the stairs, onto handcarts, then through here."

"Possibly," Kael answered.

Iris looked at the wheel grooves.

"Likely."

Kael glanced at her.

She shrugged.

"You have been correcting yourself all morning. I wanted variety."

They returned to the branch.

This time they took the descending passage.

The air cooled.

Kael’s calf began to tighten halfway down the slope, and he adjusted the cane before anyone could mention it.

Tavin noticed anyway.

"You are leaning more."

"I am walking downhill."

"That is not a medical explanation."

Kael looked over his shoulder.

"Do you rehearse these conversations?"

"No."

"That is disappointing."

The engineer interrupted them.

"Stop."

Everyone froze.

He raised the lantern toward the ceiling.

A crack crossed the arch.

Old.

Dry.

But longer than Kael liked.

The engineer examined it, then pressed his palm against the wall.

"No one touches anything. Move one at a time through the next ten feet."

Iris went first.

Kael waited.

The old instinct returned.

Move quickly.

Get through.

Solve the problem.

Instead he watched Iris reach the other side before stepping forward.

One person.

Then another.

No crowding.

No unnecessary weight.

Simple.

Boring.

Safe.

Theron would have hated how slow it was.

Kael thought of that and kept walking.

Beyond the cracked section, the tunnel opened.

Not into a cavern.

Into a room.

A rectangular chamber nearly thirty feet long, lined with old stone shelves and timber supports.

Kael stopped at the entrance.

The place was empty.

Not abandoned.

Empty.

Those were different things.

Dust covered the upper shelves.

The floor did not.

Several rectangular clean patches marked places where crates had recently rested.

Packing straw gathered in one corner.

A broken slat lay beneath a shelf.

Rope fibers clung to an iron hook.

Tavin moved to the side of the doorway, shield coming off his back.

Not because anyone had attacked.

Because this was a room people used.

Iris stepped inside.

Kael followed after the engineer cleared the floor.

The first thing he noticed was the smell.

Dry wood.

Oil.

Old stone.

Something sharper beneath it.

Salt.

Maybe.

He moved toward one of the shelves.

White grains had collected in a crack between two stones.

Iris touched one to the tip of her finger, tasted nothing, then frowned.

"You are not going to ask why I didn’t put unknown powder in my mouth?"

"I was considering it."

"Good."

The engineer rubbed the grains.

"Salt."

Kael looked around.

"Food?"

"Preserving. Trade. Hides. Could be several uses."

No answer.

Only possibility.

Tavin crouched near another clean patch.

"Here."

A thin strip of wood lay beneath the shelf.

Kael moved closer.

Not part of the crate.

A cargo tag.

Or what remained of one.

Most of the painted surface had been scraped away.

A few dark marks remained near the edge.

Perrin might recognize the style.

Kael did not touch it.

"Iris."

She crouched.

"Deliberately scraped."

"Can you tell when?"

"No."

"What can you tell me?"

She pointed to the wood curls trapped beneath the shelf.

"Someone scraped it here."

Kael followed her finger.

Tiny colored flakes remained among the curls.

Blue.

Red.

Black.

More than one tag.

More than one shipment.

The operation was not simply hiding crates.

It was removing identities from them underground.

Kael looked at the clean rectangles on the floor again.

"How many?"

Iris scanned the chamber.

"Recently?"

"Yes."

"At least twelve crate positions. Could be more if they stacked."

Tavin examined the shelf supports.

"They stacked."

He pointed toward scuff marks higher on the wall.

Two levels.

Maybe three.

Kael felt something settle unpleasantly in his stomach.

Six unexplained wagons yesterday.

Four during the previous closure.

Two before that.

Not a coincidence.

Not a single thief.

A working route.

The engineer moved toward the rear wall.

"There is another opening."

It had been concealed less carefully than the stone-yard entrance.

A timber door painted to match the dark wall.

The paint had worn away around the handle.

Iris crouched before it.

"Boot traffic."

Kael looked at the floor.

Several overlapping prints.

Broad soles.

Narrow heels.

At least four patterns he could distinguish without training.

Iris saw more.

"Six."

Kael turned.

"Six people?"

"At least six different boots passed through this room recently."

Tavin exhaled.

"That does not count wagon drivers above."

"Unless some are the same people," Kael answered.

The network grew with every answer.

They opened the rear door after the engineer checked the frame.

Another passage.

Narrower.

The old cart grooves continued.

Fifty feet farther, they found a second chamber.

This one had not been cleared.

Three broken crates remained.

One had split along the bottom.

The contents were gone, but dark stains marked the wood.

Kael crouched.

"Oil?"

The engineer smelled it.

"Could be lamp oil."

The second crate held cloth scraps.

Not clothing.

Packing cloth.

The third had several bent iron fittings inside, too small and ordinary to explain anything.

Iris lifted one with two fingers.

"Hardware."

Tavin looked at Kael.

"Not exactly forbidden goods."

"No."

That made the operation more interesting.

If they had discovered poison, illegal weapons, or stolen Imperial relics, the decision would have simplified.

Instead they had salt residue.

Lamp oil.

Iron fittings.

Scraped cargo tags.

Things merchants moved every day.

Things nobody would question in a wagon.

Kael looked at the removed markings.

"Maybe the goods are not illegal."

Iris put the fitting back.

"Only the movement."

"Or the ownership."

Tavin leaned against nothing, careful of the old walls.

"Stolen cargo?"

"Possibly."

"Tax evasion?"

"Possibly."

"Smuggling?"

"Possibly."

Iris glanced at Kael.

"You appear to have developed a favorite word."

"I dislike conclusions that arrive before evidence."

"That is less entertaining than your previous habits."

He ignored her.

The passage continued.

At the next intersection, they stopped long enough to send the engineer back to the stone yard with updated distances.

Perrin answered from above twenty minutes later through a simple system they had agreed on before entering.

Three heavy knocks.

Pause.

Two.

The sound came faintly through the ceiling.

Kael looked upward.

Perrin was above them.

Not directly.

Close.

The map placed the underground branch beneath an old field track west of Stonebrook.

Kael marked it.

They continued.

The deeper they went, the clearer the system became.

These were not random tunnels.

They had been built for maintenance and river work, then modified over decades as roads changed above.

One branch ended in a collapsed drainage outlet.

Another rose toward a sealed stair beneath what the surface map identified as an abandoned storage foundation.

A third led to an old river access where stone steps disappeared beneath muddy water.

Recent rope marks scarred the railing there.

Kael stood on the last dry step and looked at the river.

"A boat."

Perrin was not there to answer.

Iris was.

"Or a barge."

The waterline showed scrape marks against the stone.

Not old.

Fresh enough that algae had been rubbed away in three long patches.

Kael stared at them.

The operation did not only connect roads.

It connected road to tunnel.

Tunnel to river.

Wagons could enter Blackwood under legitimate-looking merchant traffic, disappear onto the service road, unload underground, have cargo marks removed, then move goods by handcart to another exit or down to the river.

Or the process could work in reverse.

Goods could arrive by boat, enter underground, emerge as ordinary wagon cargo, and rejoin surface trade without ever passing through the expected road records.

Perrin had been right yesterday.

The bridge was an expensive thought.

This was more expensive.

Kael opened the map again.

"How close are we to the bridge?"

Iris studied the marked distances.

"Farther downstream now."

"And Stonebrook?"

"Still west of the main village center."

Tavin looked toward the river.

"So whoever built this did not need to pass through the village."

"No."

Kael felt the significance immediately.

No innkeeper needed to know.

No market clerk needed to see the goods.

No road toll needed to be avoided because there was no toll.

This route avoided records.

Witnesses.

Questions.

That narrowed motive.

Not enough.

But some.

They returned to the main storage chamber near midday.

Mira had joined them by then, entering only after the engineer cleared the route from the stone yard. She brought charcoal, paper, string, and the kind of expression that suggested Galahad had told her to document everything anyone touched.

She stood in the middle of the chamber, turning slowly.

"This is larger than the Guild expected."

Kael looked at her.

"What did the Guild expect?"

"A concealed route."

"This is a concealed route."

"This is infrastructure."

That word landed.

Infrastructure.

Not criminals ducking through a hole.

Not two smugglers improvising.

Infrastructure had schedules.

Maintenance.

Replacement rope.

Lamp oil.

Greased hinges.

Timber braces.

People who knew when to repair a ceiling.

People who moved goods often enough to scrape cargo marks underground rather than risk doing it above.

Mira crouched near one of the clean crate patches.

"How long?"

Iris answered from the doorway.

"Recent heavy use. Older occasional use."

"Months?"

"Possibly."

"Years?"

"The passage itself, obviously. This operation in its current form? I cannot prove years."

Kael looked at the fresh oak brace.

He had seen that timber before.

New bridge stock.

The road crew had replaced supports three weeks ago.

Someone had access to the same kind of lumber.

That did not mean they stole it from House repairs.

But it made another question necessary.

"How much timber went missing during the bridge work?"

Mira looked up.

"I don’t know."

"Find out."

She wrote it down.

Tavin moved near the entrance.

"I found something."

He had been examining the wall beside the main cart grooves.

A series of shallow notches had been carved into the timber frame.

Not random.

Grouped.

Two cuts.

Space.

Four cuts.

Space.

Six.

Kael stared.

The room seemed to contract around him.

Perrin’s counts.

Two unexplained wagons during the earlier closure.

Four during the next.

Six yesterday.

Iris came closer.

"That is convenient."

"Too convenient?"

"Maybe."

Kael leaned in.

The cuts were fresh enough that pale wood showed beneath darkened surface.

But not equally fresh.

The group of two had darkened more.

The four less.

The six newest.

Tavin looked from the marks to Kael.

"Same sequence."

Mira’s charcoal stopped.

Kael felt his first instinct rise.

Proof.

Then Iris spoke.

"Could be crate counts."

Kael looked at her.

"Could be work shifts."

Mira added, "Could be days."

Tavin nodded.

"Could be nothing connected to the wagons."

Kael breathed out.

Good.

He hated them.

That meant the system worked.

"Document it," he ordered. "Do not call it wagon counts in the report. Call it three groups of recent tally marks: two, four, six."

Mira wrote exactly that.

Galahad would probably approve.

Kael decided not to think about it.

The next discovery came from Perrin.

Not underground.

Above.

They were halfway through mapping the western branch when three knocks sounded through the ceiling, followed by a rapid pattern that meant return to the stone yard.

No emergency signal.

No danger.

A surface finding.

Kael led the group back slowly enough that his calf remained functional.

By the time they emerged into daylight, the sun had moved past noon.

Perrin waited beside an empty wagon.

Not one of theirs.

Kael stopped.

"Where did that come from?"

"Half a mile north."

Perrin pointed toward the old service road.

"One of my riders found it behind a stand of alder trees. No horses. Shafts tied up. Wheels muddy."

Iris walked around it.

The wagon looked ordinary.

That was the problem.

No merchant colors.

No owner mark.

No cargo cover.

The bed had been swept.

Perrin climbed onto the rear wheel and pointed down.

"Not well enough."

Kael stepped closer.

A few grains lay trapped between the boards.

Barley.

Near the front corner, a faint dark ring stained the wood.

Oil.

A short strand of blue packing cloth had caught beneath a nail.

Kael looked back toward the tunnel entrance.

Salt.

Oil.

Cloth.

Iron.

Barley.

Everyday goods.

Perrin climbed down.

"Wheel width matches one of yesterday’s tracks."

"One?"

"One. I won’t pretend I can identify four identical wagon wheels from mud."

Kael nodded.

"Any owner?"

"No."

"Horse tracks?"

"Yes. Led away north, then onto hard road. Lost them."

Iris checked the wagon tongue.

"Recently unhitched."

Perrin gave her a look.

"Thank you."

"You are welcome."

Kael walked around the wagon.

Nothing illegal.

Nothing dramatic.

Just a vehicle that officially did not exist, abandoned near a hidden logistics route carrying traces of the same kinds of goods found underground.

Mira stood beside him.

"If we seize it publicly, they know."

"They already may know."

"Because the wagons stopped last night."

"Yes."

Perrin folded his arms.

"Could have stopped because this one broke."

Kael glanced at the wheels.

"Did it?"

"No."

"Then why abandon it?"

Perrin shook his head.

Kael examined the road.

Possibilities multiplied.

Someone knew they were watching.

Someone had cleared equipment.

Someone planned to recover the wagon later.

Someone had used it only as a transfer vehicle.

Someone had left it as bait.

He was growing tired of someone.

Galahad approached from the stone-yard entrance with the assessment ledger tucked under his arm.

Kael looked at him.

"Do not."

"I haven’t asked anything."

"You are thinking about it."

"That is not currently prohibited."

Galahad stopped beside the wagon.

"What do you do?"

Kael stared.

There it was.

Of course.

He looked at the empty wagon again.

"Nothing."

Galahad’s eyebrow rose.

"For now," Kael added. "We document it, leave it where it is, and watch from farther out."

"Why?"

"If they intend to recover it, I want to know who comes."

"What if they burn it?"

"Then we lose a wagon we have already documented."

"What if they use it to move more goods?"

"We watch what they load."

"What if they discover your watcher?"

"We use more than one observation point and keep them outside the immediate yard."

"What if the person who comes is armed?"

"Watching someone with a sword is not grounds to attack them."

Galahad’s expression did not change.

"What if the wagon leaves Blackwood?"

Kael looked toward Perrin.

"Perrin follows from the surface using riders in stages. No single rider stays close enough to be obvious."

Perrin nodded slowly.

"That can work."

Galahad opened the ledger.

Kael groaned.

"This is becoming harassment."

"You registered voluntarily."

"That remains under review."

Mira coughed into her fist.

They returned underground once more before ending the day.

Not to explore farther.

To complete the map.

That distinction mattered.

Kael no longer wanted to see what lay around every turn simply because the turn existed.

The engineer closed two branches as unsafe.

Kael accepted both.

One contained standing water deep enough that they would need pumps or a different approach.

The other had a collapsed ceiling with recent cracks spreading through the arch.

Iris disliked leaving them unmapped.

Kael did too.

They left them anyway.

By late afternoon, their map showed five confirmed surface or river connections.

The stone yard.

The downstream bridge entrance.

The old river steps.

A sealed stair beneath an abandoned foundation.

A narrow drainage outlet too small for cargo but large enough for air and possibly a person crawling without equipment.

Three storage rooms.

Two cart routes.

One unsafe flooded branch.

One collapse.

And several passages they had not entered.

Kael stood in the largest chamber while Mira finished the final measurements.

The picture no longer looked like an old tunnel.

It looked like a system.

A forgotten system.

A stolen system.

The difference mattered.

Tavin leaned against the doorway, careful not to touch the wall.

"How many people would it take?"

Kael looked at him.

"To run this?"

"Yes."

Perrin had joined them underground for the final review after his surface work ended. He answered before Kael could.

"Depends on volume. Six wagons? Drivers alone give you at least six unless people rotated. Then unloading crews. Handcart teams. Someone managing the river access if boats are involved. Someone arranging goods. Someone arranging buyers or deliveries."

Iris added, "Someone maintaining the tunnels."

Mira looked toward the modern lantern.

"Someone obtaining legitimate-looking cargo names."

Kael folded the map.

"And someone who knew when bridge closures would happen."

Silence.

That was the ugliest part.

The first closure could have been exploited after the fact.

The second too.

But yesterday’s collapse had been caused deliberately.

Someone had known traffic would be diverted because someone had made certain it would be.

Did that person work with the road crew?

Did they watch repairs?

Did they simply study the bridge enough to know how to damage it?

Had they influenced the earlier closures too?

Kael did not know.

He refused to turn uncertainty into accusation.

Perrin looked at the tally marks.

"If the two, four, six really are wagon counts, then they increased volume each time."

"Testing capacity," Mira murmured.

Iris glanced at her.

"Or testing whether anyone noticed."

Kael looked around the room.

That possibility felt right enough to be dangerous.

Small shipment.

No response.

Larger shipment.

No response.

Then six wagons during a closure created by sabotage.

The network might not have been hiding from Blackwood because Blackwood had never been looking.

He thought of Edwin’s ledgers.

Road counts.

Repair schedules.

Market records.

All the pieces had existed.

Separately.

Nobody had reason to place them on the same table.

Until a bridge almost killed someone.

Kael rested both hands on the cane.

"This is what they relied on."

Tavin frowned.

"What?"

"That every institution sees only its own piece." Kael looked toward the scraped cargo tags. "Road crews see repairs. Market clerks see wagons. Merchants see delays. Guild escorts see routes. Villages see strangers. Nobody sees enough alone to know there is a system underneath them."

Mira’s expression changed.

Kael continued.

"So from now on, they share."

He turned toward her.

"Guild gets road closure notices automatically."

Then Perrin.

"Transport records flag unexplained detour traffic."

Toward Iris.

"Any hidden route found by House scouts goes into a central map, even if it looks useless."

Tavin understood before Kael finished.

"And engineering records?"

"Linked to the same archive when they involve roads, bridges, tunnels, culverts, old foundations, or drainage works."

Mira looked at the chamber.

"You are changing Blackwood procedure because of this."

"I am changing it because this was possible."

Kael thought of Theron again.

Not the man.

The structure around him.

One person holding too much information.

Too much authority.

Too few people able to stop him.

Stonebrook was the opposite problem.

Too many people holding too little information.

Both failures came from separation used badly.

Institutions needed boundaries.

They also needed ways to speak to one another.

Galahad waited at the stone yard when they emerged for the final time.

Kael expected the ledger.

Instead Galahad looked at the map.

"What did you find?"

Kael gave him the short version.

Not conclusions.

Evidence.

Confirmed connections.

Recent repairs.

Multiple boot patterns.

Storage chambers.

Removed cargo identities.

Ordinary trade residues.

River access.

Abandoned wagon.

Tally marks.

At least six recent users.

No confirmed contraband.

No confirmed owner.

No confirmed buyer.

No confirmed mastermind.

Galahad listened.

When Kael finished, he looked toward the hidden entrance.

"Shut it down?"

The question came without the tone of an assessment.

Kael recognized that immediately.

This was not about rank.

This was the decision.

He looked across the stone yard.

They had enough evidence to close the tunnels tonight.

Post guards at every known entrance.

Seize the wagon.

Search warehouses.

Question merchants.

Arrest anyone returning.

He could do it.

By tomorrow morning, this route would stop functioning.

Blackwood would be safer.

For a while.

But whoever organized it would know exactly what they had discovered.

Records would vanish.

Other routes might disappear.

Drivers would scatter.

Buyers would deny everything.

And the people who had cut the bridge might never come back.

Kael thought of the injured worker screaming when they freed his leg.

Waiting had a cost too.

He had learned that in the Caldera.

Information could become an excuse.

A man could always ask for one more test.

One more record.

One more day.

Until waiting became its own decision.

Kael looked at Galahad.

"Not tonight."

Galahad did not react.

Kael continued before anyone could mistake that answer for hesitation.

"We watch the known entrances. We track the abandoned wagon. We inspect any movement for immediate danger. We do not allow another bridge, road, building, or civilian to become part of their cover."

Iris crossed her arms.

"And if they come back?"

"We follow the network upward."

Perrin frowned.

"How long?"

Kael looked at the bridge road beyond the trees.

That was the question that mattered.

Not whether surveillance could reveal more.

How long he was willing to risk waiting.

"Forty-eight hours."

Mira looked at him.

Kael held up one hand.

"Hard limit. Not an invitation to extend it because we almost learned something. Forty-eight hours unless there is immediate danger first. If we identify leadership sooner, we act sooner. If anyone prepares sabotage, violence, trafficking, dangerous magical cargo, or anything that puts civilians at direct risk, surveillance ends immediately."

Galahad studied him.

"And if forty-eight hours gives you nothing?"

"We close the network anyway."

Iris nodded.

Perrin did too.

Tavin looked toward the concealed door.

"A deadline."

"Yes."

Kael felt the decision settle.

Information mattered.

So did knowing when enough was enough.

Galahad opened his ledger.

Kael stared at him.

"You were waiting."

"Yes."

"I dislike you."

"That is unrelated to rank."

The pen moved.

Kael looked toward the road before annoyance could win.

Stonebrook Bridge remained closed.

The tunnels beneath Blackwood remained open.

For two more days, that would be deliberate.

Not because Kael had failed to act.

Because he had chosen what action came next.

Someone had built a hidden road beneath his land.

Someone had used broken bridges and diverted traffic to conceal it.

Someone had moved goods through Blackwood while every office above saw only a fraction of the pattern.

Now Kael saw the system.

The next question was whether he could learn who stood at the other end before they realized he was looking back.
