Chapter 171
The vibration ended, but the silence it left behind felt heavier than the sound itself.
Marcus remained crouched behind the broken parapet, one hand resting against the stone while he waited for another pulse. None came. Below them, the buried city resumed its labor with disturbing precision, as though the interruption had been part of a routine repeated countless times. Chains rattled, carts began moving again, and hundreds of prisoners returned to striking the black structure without hesitation.
Tomas slowly lowered his binoculars.
"That wasn’t random."
"No," Marcus replied. "They were expecting it."
"Every Collector stopped at the same time."
Marcus looked toward the dark metal rising from the center of the excavation. "Whatever is inside that structure has authority over them."
Selvar shifted uneasily beside the wall. "Emil said something spoke."
Marcus nodded.
"And when it did, even the larger creatures obeyed."
No one needed to say what that meant. The Collectors were not the highest form of intelligence beneath the earth. They served something else, whether willingly or through fear, and that something remained sealed behind a material their tools could not penetrate.
Marcus checked his watch.
They had been observing the city for nearly three hours.
It still wasn’t enough.
"Continue reconnaissance," he ordered. "We don’t move until we understand their patterns."
The team divided the buried city into sectors. Tomas focused on Collector patrol routes while Rolf tracked the prisoners’ work cycles. Cole and the engineers studied the ruins for hidden access points. The remaining soldiers rotated between security and observation, ensuring no one remained exposed near the overlook for too long.
Slowly, the city began revealing its structure.
The Collectors organized themselves into recognizable groups.
The smallest creatures rarely approached the prisoners. They moved through narrow openings between buildings, carrying fragments of shell, fungus, and strips of raw flesh in their mandibles. Their pale bodies lacked the heavy armor of the hunters, and they disappeared whenever larger Collectors passed nearby.
"Workers," Tomas concluded.
"Or juveniles," Rolf suggested.
Marcus watched one of the small creatures climb a wall with surprising speed before slipping into a hole above the third floor.
"Possibly both."
The six-legged hunters formed the most common caste. They escorted work gangs, patrolled streets, guarded intersections, and reacted aggressively whenever prisoners slowed. These were the same creatures Atlas had already fought in the Underroad, though many inside the city wore crude metal plates strapped over their natural armor.
Then came the guards.
They were larger than the hunters, with crushing forelimbs and thick overlapping shells across their backs. They remained near important buildings, excavation entrances, and prisoner compounds. Unlike the others, the guards did not waste energy chasing minor disturbances. Smaller Collectors responded to their clicks immediately, suggesting a higher position in the hierarchy.
Rolf eventually located another caste.
"Northwestern street. Near the collapsed tower."
Marcus shifted the spotting scope.
The creature stood almost twice as tall as an ordinary hunter.
Its front limbs were longer and thinner, ending in curved appendages resembling blades. The shell along its back formed jagged ridges, while dark sensory organs clustered around its head. It did not guard prisoners or carry materials.
It watched.
The creature turned slowly from side to side, remaining motionless for several minutes before moving to another elevated position.
"Sentry," Tomas said.
"Better senses," Marcus added. "Possibly sight, sound, or vibration."
Cole looked toward the team’s position.
"Can it detect us?"
"Not yet."
Marcus wasn’t willing to assume that would remain true.
Every new caste complicated the operation. Atlas had entered expecting intelligent predators. Instead, they had found an organized species with specialized labor, military roles, command structures, and an economy built around captive workers.
The city was not merely occupied.
It was governed.
Six hours passed.
The first prisoner shift ended.
A sharp sequence of clicks echoed across the excavation, followed by the sounding of a heavy bronze plate somewhere near the central district. Work gangs stopped simultaneously and began forming lines. Collectors unfastened chains from fixed anchors but kept the prisoners linked together before marching them away from the black structure.
Marcus watched the six missing civilians carefully.
They were taken east.
"That gives us movement," Tomas said.
"Track them."
The prisoners crossed two plazas before entering a district surrounded by high stone walls. Ancient residential buildings had been connected using scavenged beams, bone barricades, and crude gates. Guard towers overlooked every entrance.
A prison compound.
Rolf counted at least nine separate work gangs entering the district.
"Over three hundred prisoners."
"And that’s only one compound," Marcus replied.
Additional groups moved toward the southern and western districts, confirming the city contained multiple holding areas. The total population could easily exceed a thousand captives.
Selvar stared through the binoculars in disbelief.
"There aren’t that many people in the Underroad."
Marcus understood immediately.
"Then they’re taking people from the surface."
"From where?"
"Everywhere."
The unanswered disappearances throughout Cedric’s territory were likely only a small part of the Collectors’ operations. If tunnels extended beneath other provinces, settlements, or kingdoms, entire populations could have vanished without anyone realizing the same enemy was responsible.
The implications reached far beyond Lord Cedric’s contract.
Marcus pushed the thought aside.
First, they needed to survive the city.
The prisoner compound remained active during the rest period. Unchained servants distributed wooden bowls through barred windows while guards patrolled the walls. Some prisoners were taken into separate buildings, possibly for medical treatment or interrogation, though Atlas could not determine which.
The six civilians remained together.
That mattered.
"They haven’t separated them yet," Tomas observed.
"Which means they probably arrived recently."
Marcus studied the surrounding streets.
The eastern compound stood near a partially collapsed aqueduct. An elevated channel crossed above the outer wall before disappearing into a building inside the prison district. Most of the stonework remained intact.
He pointed toward it.
"There."
Cole adjusted his scope.
"The aqueduct?"
"It crosses the wall."
"It’s exposed for almost a hundred meters."
"But elevated."
Cole studied the route more carefully.
Several connecting rooftops led toward the aqueduct from the city’s outer ruins. Most were inaccessible from street level without climbing equipment, but Atlas had carried exactly that.
"The channel might be dry," the engineer said.
"Or partially blocked."
"Still better than the gates."
Marcus agreed.
The aqueduct provided a possible entry into the prisoner compound, but reaching it required crossing several occupied districts. They still needed a hidden path from the overlook to the city floor.
Cole found one shortly before the end of the observation cycle.
A drainage opening sat beneath the balcony, nearly invisible behind hanging fungal growth. The channel descended through the cliff face before emerging among abandoned buildings at the city’s northern edge.
"It’s narrow," Cole explained. "Single file. Maybe seventy meters down."
"Anchors?"
"Ancient iron brackets inside the shaft."
"Trustworthy?"
"No."
Marcus almost smiled.
"Then we use our own."
The route was dangerous but workable.
The plan began taking shape.
Atlas would descend through the drainage shaft after the next work shift began. They would move through abandoned northern buildings, avoid the main streets, and establish a temporary hide inside the old defensive quarter. From there, a smaller reconnaissance team would advance across the rooftops toward the eastern prison compound.
No direct assault.
No rescue attempt yet.
First they needed to enter the city, confirm the aqueduct route, locate alternate exits, and identify where the Collectors kept the keys or restraints.
The team would remain invisible for as long as possible.
Marcus gathered the senior soldiers behind the camouflage netting.
"We divide into three elements."
Tomas opened the map.
"Point team?"
"You, Cole, four riflemen, and Selvar."
Selvar stiffened.
Marcus looked at him directly. "You can read more of the old inscriptions than anyone here. We may need that."
The Underroad leader hesitated before nodding.
"Second element stays with me. Third element holds the overlook and maintains the relay."
Rolf frowned.
"How many remain behind?"
"Six."
"That leaves eighteen entering the city."
"Correct."
Tomas traced the route with his finger.
"Once inside, we establish a hide here."
He indicated an ancient barracks near the northern wall.
"Assuming it’s empty," Cole said.
"We confirm before occupying it."
"And if it’s not?"
Marcus answered calmly.
"Then we find another building."
The plan remained deliberately flexible. Maps based on distant observation could not account for blocked passages, hidden nests, or interior patrols. Atlas would need to adapt without revealing its presence.
Rolf looked toward the prisoner compound.
"What about the six civilians?"
"We observe them tonight."
"And if they’re moved?"
"Then we follow."
Rolf’s jaw tightened, but he nodded.
Everyone wanted to rescue the captives immediately. Marcus wanted it too. Yet rushing into the compound without an escape route would turn a rescue into a massacre.
He looked around the group.
"Our priority is intelligence. No firing unless concealment is already lost or someone’s life is in immediate danger. Suppressors remain attached. Blades first whenever possible."
Tomas added, "Bodies must be hidden."
"Exactly."
Marcus pointed toward the city.
"We are entering an occupied capital controlled by an enemy that communicates faster than we understand. If one patrol gives the alarm, we could have hundreds of Collectors closing on us within minutes."
The soldiers listened without interruption.
"This is not an assault," Marcus continued. "It is infiltration. We enter quietly, learn the terrain, and leave with a complete plan. We rescue the prisoners when we can extract them without losing half the city."
No one argued.
The next work shift began four hours later.
The bronze plate sounded again.
Prisoners emerged from the compounds and marched toward the excavation while Collector patrols concentrated along the main avenues. The northern ruins became noticeably quieter as the enemy’s attention shifted toward the labor operation.
Marcus gave the order.
"Prepare to descend."
Cole and the engineers moved first.
They crossed the overlook on hands and knees, secured climbing anchors around a massive stone column, and fed black ropes into the drainage shaft. A small camera descended ahead of them, transmitting grainy footage to a handheld screen.
The shaft twisted through the rock.
Broken pipes and roots protruded from the walls.
Nothing moved.
At the bottom, the camera revealed ankle-deep water flowing through a narrow channel beneath the city.
"No visible hostiles," Cole reported.
Tomas checked his weapon.
"I’m first."
Marcus nodded.
"Go."
Tomas clipped onto the rope and disappeared into the drainage opening without another word. Cole followed, then two riflemen. Each soldier waited until the previous member reached the lower section before entering, preventing too much weight from loading the anchors at once.
The descent took nearly twenty minutes.
Radio signals weakened inside the shaft but remained functional through the relay system.
"Bottom secure," Tomas finally whispered.
Marcus entered next.
The drainage tunnel pressed tightly around his shoulders. Centuries of mineral buildup covered the walls, forcing him to turn sideways through several sections. Warm water soaked his boots while the distant pounding vibrated through the stone around him.
Halfway down, he passed an ancient iron bracket embedded in the wall.
Something had been carved beside it.
A crown.
Beneath the crown was an open mouth filled with teeth.
The Mouth Beneath.
Marcus paused only long enough to memorize the symbol before continuing.
When he reached the bottom, Tomas pulled him into the shadows beside the channel.
The city felt different from below.
Much larger.
Much louder.
Ancient buildings towered above the narrow drainage exit, their broken windows disappearing into darkness. Fungal growth hung from balconies while smoke from distant fires drifted between rooftops.
The air smelled of wet stone, ash, and decay.
Marcus waited until the final soldier descended.
Eighteen Atlas personnel gathered inside the drainage channel.
Cole recovered the rope but left one hidden line in place for emergency withdrawal. The upper team concealed the shaft entrance again with fungal growth and camouflage material.
Their return route remained open.
For now.
Tomas peered over the edge of the channel.
"Street is clear."
Marcus checked the illuminated map attached to his forearm.
"Barracks should be two blocks south."
The team climbed from the drain one by one.
No lights.
No voices.
They moved through the ruins using night-vision equipment, crossing alleys filled with broken statues and abandoned carts. Every sound seemed amplified beneath the cavern roof.
A chain scraped somewhere nearby.
The formation froze.
Clicking followed from the next street.
Two Collectors passed the intersection less than thirty meters away.
They moved slowly, forelimbs tapping against the pavement while their heads turned from side to side. One paused near the alley entrance.
Marcus raised a closed fist.
Every soldier became motionless.
The creature took another step.
Its head tilted.
For several seconds it stared directly into the darkness where Atlas waited.
Then a distant signal echoed from the excavation.
The Collector clicked in response and continued walking.
Its companion followed.
Only after both disappeared did Marcus lower his hand.
The team moved again.
They reached the ancient barracks without further contact.
The building’s entrance had collapsed, but Cole found a gap beneath the eastern wall. One by one, the soldiers crawled inside.
The interior remained mostly intact.
Rows of stone sleeping platforms lined the walls. Rusted armor hung from wooden frames preserved by the dry air. A cracked staircase led to an upper level overlooking the street.
No Collectors.
No prisoners.
No recent tracks.
Marcus established security immediately.
Two soldiers covered the entrance.
Two climbed upstairs.
Cole checked the rear rooms for alternate exits while Tomas positioned a small camera near a broken window.
For the first time since entering the city, Atlas had cover.
Marcus opened the map across an ancient stone table.
"We’re inside."
Tomas looked toward the east.
"Now we find the aqueduct."
A sudden click sounded from somewhere beneath the floor.
Everyone froze.
Another click answered from deeper inside the building.
Not from the street.
From below them.
Marcus slowly raised his rifle.
The ancient barracks was not empty after all.
