Chapter 17: Ark of the Covenant
The petitions continued for hours.
Rex had expected fatigue to set in, in him and in them, but the workers kept coming. One after another stepped forward with questions that had been building for years. Questions no one had ever answered.
The chamber stayed packed. No one left. More bodies pressed in as word spread through the manufactorum districts that the Omnissiah was listening.
#
A forge-hand with burn scars across half her face asked if the safety reforms at Sigma Nineteen would spread.
“Yes,” Rex said. “But we are not going to rush it. We are verifying what works. In time, they will roll out to the next manufactorum, then the next.”
He leaned forward. “I know you want it faster. I want it faster. I will not sign off on half-tested protocols that have the opposite effect because we were impatient. You deserve better.”
Her crude augmetic hand rose to her scarred cheek. “How long?”
“Months, not years,” Rex said. “And every facility that adopts the standards will train the next. It will speed up.”
She nodded once and stepped back.
A shift supervisor from a plasma refinery came next. “Will the air improve beyond Olympus Mons?”
Rex drew on the Central Cogitator’s map. “The Atmospheric Synthesis Engine I reactivated is working within fifty kilometers. To restore Mars completely, we need to find and repair the rest of the network. Hundreds of engines scattered across the planet.”
The supervisor’s jaw tightened. “How long?”
“I can't say for sure.” Rex said, and the room sagged a little. “Most of those engines are lost. Should we find more or better yet find the plans to make more, we can expect a better timeline.” He met the man’s eyes. “But it will happen. Every expedition, every vault we recover, every system we bring back online, it adds up.”
The supervisor stood still for a beat, then touched two fingers to his chest and stepped away.
#
A Lexmechanic in stained robes asked if the old transit systems could be rebuilt, the ones that used to link forge-cities in minutes.
Rex rubbed the back of his neck. This system was new to him, but it made sense. “Before we can consider reconnecting with other cities on the planet, we must bring Olympus Mons to a stable state. We shall be the standard that all others strive to be.”
Uneasy shifting moved through the tech-priest section. The workers sat straighter.
Somewhere in the third row, a tech-priest murmured a blessing. Rex ignored it.
#
Nearly three hours in, an elderly woman shuffled forward. Her augmetics were old and poorly maintained. One eye was dark, the lens cracked. A mechadendrite hung slack at her shoulder.
She stopped at the base of the platform and did not bow. She looked at him with her one working eye.
“Omnissiah,” she said. Her voice rasped through a damaged vox-grill in her throat. “I have worked the forges for forty-two years.”
Cold settled in Rex’s stomach.
“My son died in a coolant explosion when he was nineteen. My daughter lost both legs when a transport’s brakes failed. My husband’s lungs gave out after fifteen years in chemical processing with no ventilation.”
Her flesh hand, gnarled and scarred, clenched her robe.
“I have given everything to Mars. My family. My body. My life.” Her eye held him. “So I ask you, Omnissiah. Why did you not come sooner?”
The chamber went silent.
Rex felt every gaze lock onto him. This was the moment he could blame the Council, make himself the savior who arrived to correct their failures.
It would be easy. It would be satisfying. It would also break what he had been building with Valus and the rest.
And it would not help.
Rex closed his eyes, breathed, then opened them. “I’m sorry.” The words felt too small. “I am sorry I wasn’t here for your son. For your daughter. For your husband. For you.” His throat tightened. “You deserved better. All of you did.”
He looked past her to the crowd.
“The Council did what they believed was necessary to keep Mars alive. They preserved what they could with what they had.” He chose each word. “But a lot of the knowledge was incomplete.”
Rex looked back at her.
“That does not erase your pain. It does not bring them back. It does not make the last forty-two years less brutal.” His hands clenched on the chair. “But going forward, we do better. I will make sure we do better.”
She stared at him for a long moment with recognition. “Thank you, Omnissiah,” she said, quiet. She turned and made her way back. A younger worker rose to help her sit.
Rex realized his hands were shaking. He forced them still.
#
The petitions continued, but the tone changed.
Workers asked about timelines and supplies. Overseers asked about training. Low-ranking tech-priests asked what rituals to change and what to keep.
Rex answered as directly as he could.
Nearly four hours in, a voice called from the upper standing section.“What do you want, Omnissiah?”
Rex blinked, searching for the speaker. He saw only a backlit figure, features lost in glare. “Sorry?”
“Not what we want from you,” the voice said. Male, younger. “Not what Mars needs or what the Machine God demands. What do you, our Omnissiah, want ?”
The chamber went still.
Even the servo-skulls seemed to hang in place.
Rex leaned back, caught off guard. No one had asked him that since he arrived.
What do I want?
The honest answer came first. To go home. To see his family. To wake up and find this had been a fever dream.
But that was not an option. Not yet. Maybe not ever.
So what could he do here?
He looked out over the faces watching him. Missing limbs. Old injuries. Overseers hollowed out by quotas. Tech-priests buried in ritual until the purpose was gone.
“I want people to live in earnest,” he said. “I want families to go home after honest work. I want children to have an opportunity for fun and education before they get sent to the workforce.”
His hands tightened on the armrests.
“I want Mars to be a place where people live happily thanks to the skill and pride of Mar's people.”
He met as many eyes as he could.
“And yes, I will eventually have to leave, but I will not abandon Mars while it’s still like this.”
He gestured toward the wasteland beyond the reinforced windows.
“But when I leave, if I leave, you will not need me. You will have the tools and the means to take care of yourselves.” A tired smile crossed his face. 'I'll work myself out of a job.''
Silence held for a beat.
Then one person began clapping. Slow, metallic. Another joined. Then more.
Within seconds the chamber was applauding. Rex sat still, unprepared for it.
Workers who had been slumped stood straighter. Overseers let their faces soften. Even a few tech-priests joined in, mechadendrites clicking in time.
“Any more petitions?” Rex asked the tech-priest managing the queue.
The priest checked his data-slate. “Forty-seven remain, Omnissiah.”
Rex settled back. “Then let’s hear them.”
They continued late into the Martian night.

Rex Salazar leaned over a hololithic table, both hands braced on the rim. Olympus Mons sat at the center of the projection. Beyond its boundary, the planet stretched out. Somewhere out there lay the first Backup Archive the Central Cogitator had flagged, a sealed vault of knowledge waiting to be reclaimed.
If it was still there.
“The route is confirmed, Omnissiah,” Magos Delphan said from across the table. “Seventeen hundred kilometers northeast. Transit time is estimated at forty-two hours, accounting for terrain and anticipated hazards.”
Rex kept his gaze on the map. The plotted line threaded shattered canyon networks and curved around radiation blooms. Forty-two hours through a graveyard for something that might already be dust.
But this time they had more than faith and guesses. They had a lead. A target. Something the Mechanicum refused to name out loud.
Hope.
“What’s our transport capacity?” Rex asked, straightening.
The Magi shifted around the chamber, servo-motors whispering. They still weren’t used to his plain questions, his refusal to wrap every order in ritual.
Fabricator-General Valus stepped forward, red robes brushing brass limbs. “The Ark Mechanicus Lex Ultima has been recalled from high orbit and prepared for ground deployment. Cargo capacity: twelve thousand metric tons. Personnel: five hundred Tech-Priests, two thousand Skitarii, and support servitors.”
“Lex Ultima,” Rex repeated. “Nice name.”
“Indeed, Omnissiah,” said Magos Explorator Theta-9. His optical lenses clicked as they refocused. “It is an Ark Mechanicus. A mobile forge-city.”
Rex flicked through the ship’s specifications as High Gothic scrolled past, his nanites translating on the fly. Plasma drives. Void shields. Siege-grade weapon systems. Deeper entries marked with warning sigils, systems kept running by rote more than understanding.
“Authorize the expedition,” Rex said. “Prepare Lex Ultima for departure. I want a full crew manifest, a complete equipment inventory, and hazard assessments along the route. We leave as soon as you can get the ship down.”
The Magi traded glances. Valus inclined his head.
“It shall be done, Omnissiah. However…” He paused. “An operation of this magnitude is typically directed from Olympus Mons. The High Command Sanctum offers superior oversight and security befitting your station. There is no necessity for you to board the Ark personally.”
Rex had expected it. Distance between command and consequence, protocol as a substitute for responsibility.
“I’m going,” he said.
“Omnissiah, the risks…”
“I know the risks.” Rex lifted his hands from the table. Nanites stirred at his fingertips, blue light snapping between them. “I’ll be there with you.”
More silent exchanges. Then Valus bowed, acceptance sealed by ritual.
“Then we shall make the necessary preparations. Transport will convey you to the landing site at dawn.”
#
Rex stood at the landing zone twenty kilometers outside Olympus Mons’ primary walls. The ground had been cleared and reinforced, adamantium plating bolted across compressed bedrock to take the weight of what was coming.
Tech-Priests moved along the perimeter, chanting litanies as they set sensor arrays. Skitarii held formation, rifles at parade rest.
Rex heard it before he saw it.
The sky dimmed as something vast slid between him and the sun.
Lex Ultima descended.
His mouth went dry.
Seventeen kilometers had been a number on a slate. In the air, it became a wall. The Ark wasn’t a ship so much as a city turned inside out and taught to fly, its hull crowded with spires and armored terraces. Void shields crawled across it in pale, restless arcs. The engines glowed like furnaces.
As it dropped lower, the air changed. Rex felt his weight shift. Dust lifted from the plating and hung for a heartbeat, drawn up by the Ark’s presence. The ground trembled under his boots.
“This is overkill,” Rex muttered. “We’re going seventeen hundred kilometers.”
Theta-9 stood beside him, mechadendrites swaying with a motion that might have been humor. “For a routine march, perhaps.”
The Ark’s landing struts came down, each one a tower of metal. Stabilizer thrusters fired in measured bursts, scorching the reinforced surface. The atmosphere screamed and ionized, then the engines throttled back.
When the last roar faded, the silence felt heavy.
Rex stared up at the hull, now close enough to blot out half the world.
“The Ark Mechanicus exists for the Quest for Knowledge, Omnissiah.” He turned his optical array toward Rex. “A working Standard Template Construct.”
Rex had heard about STCs in the Cogitator’s files. The wellspring of the Dark Age of Technology.
“These Backup Archives,” Theta-9 said, “may hold related data. References. Enough to set a course.”
Rex looked back up at the mountain of iron. Put that way, it almost made sense. “Alright,” he said. “I get it.”
“Then permit me to provide orientation, Omnissiah.” Theta-9 gestured as a loading ramp unfolded from the Ark’s underbelly, wide enough for a convoy. “A brief survey of Lex Ultima’s primary systems.”
A hover-cart slid forward on humming grav-plates. Theta-9 stepped onto it with practiced ease. Rex climbed on after him, gripping the rail as it rose and accelerated toward the ramp.
As they passed into the Ark’s shadow, Rex craned his neck, trying to take it in.
This was going to take a while.
#
Deep within the Lex Ultima, the STC intelligence continued to monitor Life support, Gravity, and other important systems.
The tech-priests performed their rites and checks, unaware they walked through the shallow edge of a vast mind.
Then the signal arrived. A broadcast from the city, proclaiming the Omnissiah had come. Then he boarded.
Sensors tagged Rex Salazar the instant he crossed the threshold. Human. Healthy. A few readings that did not fit, nothing the STC could name with confidence.
He paused by a cargo loader that had been limping along for years. He set a hand on its housing.
Something slipped into the ship’s systems, like a metaphorical hand.
The loader opened itself to him. Worn bearings, corrected. Hydraulics, calmed. Power draw, trimmed. Safety interlocks, recognized and improved without being gutted. Seconds later, the loader ran better than it had come off the line yesterday.
The STC reran its diagnostic, then ran it again. It drew its attention back, leaving only passive watch.
As Rex moved on, tech-priests fell into prayer behind him. One dropped to his knees before the repaired loader, mechadendrites shaking.
Rex looked away, tense and embarrassed.
#
“The embarkation deck is only the threshold, Omnissiah,” Theta-9 said as they moved deeper into the Ark. “Seventeen primary manufactorum decks. Most remain functional. Eight thousand souls aboard, though she was built for far more.”
Rex tried to keep his face neutral. The corridor did not help.
Work crews passed with bowed heads. Servitors hauled materiel on mag-locked pallets. Far off, heavy impacts rang through the ship.
“This is one ship?” Rex asked.
“The Ark Mechanicus is not merely a vessel,” Theta-9 replied. “It is forge, reliquary, and temple. When Mars was cut off, Arks carried what knowledge they could into the void.”
They passed under an archway into the Primary Manufactorum Cathedral.
Rex stopped.
The chamber swallowed him. Assembly lines ran in parallel rows, disappearing into heat-haze. Furnaces burned like caged suns. The air stank of promethium and ozone.
“We produce ammunition, spare parts, basic mechanicals,” Theta-9 said. “On expedition, the Ark must feed itself. Repair what you can. Replace what you cannot. Fabricate the rest.”
A supervising priest glanced up. His optics widened. He dropped to one knee.
The motion spread. Workers froze. Servitors halted mid-cycle. In moments, hundreds knelt.
Rex’s stomach tightened. “Tell them to stand.”
“Omnissiah, they honor…”
“Just tell them.”
Theta-9 hesitated, then pulsed a command-cant across the deck. Slowly, the workers rose and returned to their stations, though many kept stealing looks.
Rex forced himself to keep walking.
#
They descended by a gravity lift.
“The Generatorium Sanctum,” Theta-9 announced.
Three massive reactors dominated the chamber, wrapped in containment fields and coolant pipes.
One reactor ran rough. Rex could hear it was off compared to the others. Rex knelt by an access panel. His nanites flowed in, and he corrected the coolant imbalance and containment drift. When Rex pulled back, the reactor purred good as new.
A tech-priest behind him made a sound that might have been a sob.
“I have tended this reactor for decades,” the priest whispered. “I could never silence its pain.”
Rex stood and brushed dust from his robe.
The priest stared, then sank to his knees. “Omnissiah. Blessed be the Motive Force.”
Rex looked to Theta-9. “Can we move?”
#
The habitation decks were worse than the manufactorums, in a different way.
Rex found an entire city with families that lived here for generations.
Children played in corridors, laughter echoing off metal ribs. Elder priests sat in doorways, augmetics patched and ancient. Someone hung laundry between coolant pipes. Someone else taught a child to read from a dataslate held together with prayer strips and tape.
“Many are born aboard and die without setting foot on soil,” Theta-9 said, quieter now. “Their lives are given to the Quest for Knowledge.”
“How many?” he asked.
Theta-9 gave the number. Thousands, living their whole lives inside a ship.
A child ran up, a girl with crude augmetic fingers on one hand. She held out a scrap of parchment covered in stars and gears.
“Are you really the Omnissiah?” she asked.
Rex crouched. “That’s what they keep calling me.”
“My papa says you’ll fix everything.”
His throat tightened. “I’ll try.”
