They had barely finished collapsing the last strut when every comm unit at their belts pinged in unison, a tiny mechanical chorus that cut through the ringing in their audios.
For a beat, the yard held its breath.
Dust drifted slow from the final pry. Sparks guttered to orange embers where Mixmaster’s torch had cooled. The smell of burnt flux and spent energon hung thick in the air, clinging to the back of every intake. The arena they had raised and then unmade sat around them in neat piles: wall sections stacked apart from seating modules, braces sorted into tidy heaps, crates lined up like the bones of something that had once stood proud.
Long Haul’s bucket already crouched by the crates, waiting like a patient engine.
Scrapper felt the vibration against his belt before he saw the light. He snapped his comlink open, optics narrowing as the message scrolled with that same clinical flash they had come to read as both ledger and verdict.
The words were spare and absolute across the screen.
[Transfer complete.]
[Credited: 1000 shanix.]
[Title: Tear Down Bonus.]
A dark little laugh escaped Scavenger, his hands clicking faster as the number sank in—bonus credits dropped into their accounts as if the command had been gentle enough to reward them for the erasure. Bonecrusher’s grin was slow and private, pride braided with the practical relief that came when pay finally matched toil. Mixmaster’s optics glittered; even exhausted, he had already imagined the compounds he might buy, the experiments he could run with a little extra energon in the stores.
Hook’s face went blank for a breath, the medic calculating the supplies it might buy against the cost they had paid to produce them.
“One thousand each,” Mixmaster muttered, already reading the transfer trail. His fingers twitched against his datapad, checking the coding twice out of habit. “Clean transfer. Same authorization pattern.”
“Megatron,” Scavenger said, voice half awe, half disbelief.
Scrapper’s mouth tightened as he looked down at the glowing message. “Soundwave processed it.”
Long Haul rumbled low in his chest. “Payment for doing the job.”
Bonecrusher glanced toward the dismantled arena, toward the piles of steel and saved hinges and scorched fragments no caste engineer would reassemble without them. “Payment for doing it right.”
No one argued.
The transfer was not praise. Not really.
It was acknowledgment.
They had built the arena. They had proven it could stand. Then they had proven it could vanish, piece by piece, leaving nothing useful behind for hands that had not earned it.
The money made that truth harder and colder.
They were not being thanked.
They were being retained.
Almost on top of the transfer came another transmission, the tone sharper this time, as if the feed had been delivered by a hand that tolerated no delay.
[New Coordinates: Sector 9, Sublevel 47.]
[Designation: Labs.]
The word landed in the yard like smoke.
Labs.
It had none of the sand and spectacle of the pits, none of the utilitarian rust of the smelting yard. It carried something colder—glass, circuitry, the sterile tang of controlled energy. The six exchanged quick, small looks.
Scrapper’s jaw tightened, not from anger but from the geometry of the idea already forming. Scavenger’s fingers stilled mid-twitch, his grin sharpening at the edges. Bonecrusher’s vents dropped low and thoughtful, reading risk as if it were weight to be carried. Long Haul’s bucket shifted, the motion almost imperceptible, logistics already drafting themselves in the back of his processor. Mixmaster’s optics flared in a way that had nothing to do with fatigue.
Curiosity.
Appetite.
Hook’s hand hovered near the subspace pocket where his repair kit rested, the medic’s caution and duty sparking like a warning light.
Everything around them held the odd stillness of a thing about to tip. The dust hung like a veil. The last sparks from Mixmaster’s torch finally sputtered out. The credit notification had been practical, transactional—payment for labor finished.
But the second message was different.
Labs.
Not pit.
Not yard.
Something else entirely.
The six felt the shift then: from spectacle to secrecy, from temporary construction to hidden infrastructure, from public proof to something buried under levels and sectors.
The word stayed in the air, thin and dangerous, settling into their chests like a new weld cooling to hardness.
Labs.
Scavenger tilted his head, hands twitching in the nervous rhythm that always betrayed him first, unease and quiet thrill warring under his plating.
“Underground?” he asked, the word small and sharp, like a probe thrown into unknown dark.
He had already pictured cramped tunnels and shadowed racks, the kind of places where his fingers had once learned to find spare bolts and forgotten hinges. Sublevels meant forgotten storage. Discarded equipment. Blind corners. Old access tunnels. Places no one checked unless something had already gone wrong.
Mixmaster’s optics gleamed with an almost feverish light as the word settled.
“Labs,” he muttered to himself, syllables of chemical names and supply lists spilling soft and fast. “Supplies, chemicals, forges—controlled energy, maybe containment rigs. Something precise. Something clean.”
The thought of controlled heat and clean reactions threaded through him like a current. His mind was already two steps past the map, tasting recipes and testing cures that would hold under stress.
Bonecrusher frowned, fingers rubbing at the grit still embedded in his knuckles as if the motion might rub away the strangeness of the order.
“Labs,” he repeated, voice rough. “Not exactly my kind of place.”
Hook gave him a sideways look. “You said that about the medical alcove too.”
“I still say that about the medical alcove.”
“You survive it.”
Bonecrusher grunted. “Barely.”
Long Haul shifted, the crates behind him clanking faintly. “Coordinates first. Complaints after.”
Scrapper did not speak immediately. He pulled the map up, fingers skimming the cold lines of the schematic until the coordinates sang in his optics. He traced the route with a fingertip, leaving a faint ghosted smear on the display.
Sector 9.
Sublevel 47.
Access would be tight. Load routes limited. Not impossible, but not comfortable. Hidden by design or neglect, maybe both. Deep enough that Senate oversight would be slow, distant, filtered through layers of bureaucracy and infrastructure no high-caste supervisor would want to walk through personally.
His optics narrowed further as more of the map resolved.
There were rooms below the lab designation.
Storage.
Maintenance.
Power routing.
A secured central chamber.
And one label that made the air in his vents go still.
Scrapper looked up.
“It’s not just labs,” he said slowly, diction careful as a suture. “One of the rooms is marked War Room.”
The name landed like a weight.
Bonecrusher’s brow plates drew low. “War room?”
His voice cut blunt through the yard, built for force, not subtlety.
“What in the slag is Megatron planning down there?”
No one answered right away.
The question hung harsh and sudden, carving a new shape into the air.
War room.
Not a medbay.
Not a workshop.
Not a hidden storeroom for arena pieces.
A room made for strategy. For maps, targets, movement, supply lines. A room where the shape of conflict would be decided before it reached the street.
Hook’s optics sharpened, and for once his silence held something colder than medical calculation.
Long Haul’s jaw set. “That means more than building.”
“Means support routes,” Scrapper said, eyes still on the map. His processor was already drafting solutions. “Supply lines. Reinforcement paths. Structural concealment. Access control.”
Mixmaster’s mouth curved faintly, less a smile than the sharpening of a tool. “Power regulation. Lab containment. Chemical storage that won’t slag itself if Bonecrusher breathes too hard near it.”
Bonecrusher turned his head slowly.
Mixmaster did not look up. “I said if.”
Scavenger leaned closer, optics bright. “Storage rooms. Old ones, maybe. Hidden ones.”
“Useful ones,” Scrapper corrected.
Scavenger’s grin twitched wider. “That too.”
Hook studied the map over Scrapper’s shoulder. “Medical space?”
Scrapper enlarged the schematic with two fingers. “Not labeled.”
“Then it will be,” Hook said.
The words came flat and final.
Bonecrusher huffed. “Of course it will.”
Hook ignored him, already measuring likely corridors and emergency access points. “If this becomes a base, injuries come with it. If Megatron works out of there, he needs treatment within reach. Shockwave will need a sterile area too.”
“Shockwave,” Scavenger echoed, hands clicking once. “Right. Labs.”
The name made them all still for half a beat.
Shockwave’s presence had already shifted things once. His observation of them had not been praise. It had been selection. Calculation. A door opening into a project none of them fully understood yet.
And now the coordinates led to labs.
Main labs, if the structure was as deep and hidden as the map suggested.
A place for Shockwave to work.
For now.
Scrapper’s jaw tightened; the angle of his mouth went hard in the way that meant his processor was no longer reacting. It was building.
He sketched layouts in the air between them as if his hands could pull the plan into existence—where supports would go, how to route supply lines, which access points would need guarding, where a lab could function without poisoning a living space, how to keep a war room close enough to command but not exposed by obvious traffic.
His next words came with the slow, certain weight of a conclusion drawn from lines and angles.
“This wasn’t another test.”
He let that settle.
“This is permanent.”
The word sat over them like dust.
Permanent.
What they had built before had proven them.
What this demanded would define them.
It meant months of structure instead of nights of scrapping. Secrets instead of spectacle. Corridors and rooms and systems that could not be torn down by dawn. Work that changed not just a mech’s life, but the map under Kaon itself.
Each of them felt that shift differently.
Scavenger’s twitch tightened into avid hunger, already thinking of what could be found in old sublevels and half-forgotten maintenance shafts. Mixmaster’s formulas sharpened into ambitious designs, the promise of a real lab lighting something dangerous behind his optics. Bonecrusher’s practical cynicism softened into grim duty, because permanent meant something to protect. Hook’s medic calculation stretched toward contingency plans, sterile rooms, emergency lines, and how to keep the others alive in a place built for revolution. Long Haul’s logistics hummed with routes and lifts, how to move the salvaged arena pieces underground without attracting the wrong eyes. Scrapper’s architecture flattened the impossible into steps.
The map glowed between them like an altar.
They stood in the remains of something mobile, something deliberately temporary, and stared at the first outline of something meant to last.
Outside, dust still hung in the yard’s air. Around them, lime green and purple caught the dim light through layers of grit. They had been painted to be seen, but now the next job would take them down into the hidden bones of the city, where visibility could kill a project before it began.
For a moment, none of them spoke.
Then Long Haul shifted his bucket toward the staged crates. “We taking all this now?”
Scrapper looked toward the sorted arena pieces, the saved panels, the packed braces, the crates Scavenger had labeled by usefulness and future role.
“We take what we can move without drawing attention,” he said. “The rest gets hidden until Soundwave sends for it.”
“He didn’t say to bring the arena,” Bonecrusher said.
“He didn’t say not to.”
Long Haul gave a slow nod. “Better to have it and not need it.”
“Better to know where it is,” Scavenger added quickly. “Some of this can stay nearby. Covered. Buried under junk. I can mark caches.”
Scrapper looked at him. “Can you find them again?”
Scavenger’s offended look came so fast it almost cut through the tension. “Of course I can find them again.”
Mixmaster muttered, “He could find one good hinge in a slag storm.”
Scavenger’s grin flashed back. “And I’d bring back three.”
Hook’s gaze swept the piles. “No unstable loads. No rushing. If we are going underground, I don’t want anyone dragging a damaged panel through a sublevel corridor and crushing his own pede.”
Bonecrusher snorted. “You always make everything medical.”
“Because everything becomes medical when someone ignores structure.”
Scrapper glanced at him. “That stays in the process too.”
Hook blinked once. “What?”
“Medical risk assessment before load movement.”
Bonecrusher groaned. “Don’t encourage him.”
“I am encouraging the useful part,” Scrapper said.
Hook’s mouth twitched faintly, but his optics were already back on the map.
The decision settled fast after that.
Not because it was easy.
Because standing still had become harder than moving.
Scrapper finally snapped the comlink shut and looked at the others, his voice sharp.
“Then we head underground.”
He glanced once toward the dismantled arena, then back to the coordinates.
“And we build him his base.”
The words landed like a final hammer strike.
For a moment, no one moved. Only the lamps hummed and the last motes of dust drifted through the shaft of light. Then the reactions came small and plain.
Bonecrusher’s shoulders lowered as if accepting the weight of the sentence, his vents rasping once like a steel bell settling. Long Haul’s bulk shifted, a plan already running behind the slow mechanics of his reply. Scavenger’s fingers found the edge of a crate and flexed, hungry and mean in the way of a scavenger who knew where to find what others missed.
Hook’s jaw tightened but his optics steadied. His repair kit remained in subspace, ready where it always rested. He did not need to touch it to know it was there.
Mixmaster’s mouth curved—less a grin than the sharpening of a tool—his optics flicking through half-formed formulas that might weld or split, hold or unmake. Scrapper’s own face went flat, the smirk gone, replaced by that hard line a leader showed when a plan ceased to be an idea and became an order.
Around them, the colors caught the light once more—lime green and purple dulled under grit and mandate, but still unmistakable.
No Megatron stood at the threshold.
No Soundwave waited in the yard.
No Shockwave’s yellow optic watched from above.
Only the text remained.
Coordinates.
Designation.
Directive by implication.
That was enough.
Long Haul moved first, lowering his bucket toward the first load. “Tell me what goes.”
Scrapper answered without hesitation. “Primary wall sections. Two brace crates. Mixmaster’s solvent case. Scavenger’s hinge bins.”
Scavenger hugged one of the smaller containers to his chest. “These come with me.”
“They can ride with the rest.”
“They’re sorted.”
“They’ll stay sorted.”
Scavenger looked deeply unconvinced, but Long Haul held out one massive hand. After a tense beat, Scavenger surrendered the crate with a muttered warning about bent pins and careless stacking.
Long Haul took it like it weighed more than it did. “I'll keep it upright.”
Bonecrusher grabbed a panel edge and hauled it toward the staging line, fresh paint scuffed, shoulders rolling under the weight. “Labs,” he muttered. “War room. Underground base. Figures we finally get out of the pits and go deeper.”
Hook stepped around a coil of cable, scanning the loads as they gathered. “Deeper can be safer.”
“Or easier to trap.”
“Then we build exits.”
Scrapper looked up from the map. “We build several.”
Mixmaster’s optics brightened. “Hidden ones?”
“Functional ones,” Hook said.
“Both,” Scrapper corrected.
That got Mixmaster grinning.
They worked quickly, not with the frantic pace of panic, but with the practiced rhythm of mechs who had learned how to move together under pressure. Long Haul took the heaviest loads. Bonecrusher cleared a path through debris and shoved aside anything that might catch a crate. Scavenger marked what stayed and what moved, his fingers leaving quick tags only he seemed able to read at a glance. Mixmaster secured volatile materials with more care than anyone expected from him. Hook checked balance, pressure, and risk, stopping one load before it shifted badly enough to crush a crate of support locks. Scrapper kept one optic on the map and the other on the team, recalculating with every movement.
By the time they left the smelting yard, it looked less like the site of a vanished arena and more like a place that had never held anything worth seeing.
The caste could come looking and find nothing but dead slag, scorched marks, and scrap too ruined to bother cataloging.
Everything that mattered had moved with them.
Or had been hidden where only they could find it again.
They descended into Kaon through an old service route Scavenger knew, one of those ugly industrial arteries the city forgot it needed until something clogged. The walls were close, scarred by heat and old repairs. Pipes ran overhead in uneven bundles, some humming with pressure, others dead and cold. The deeper they went, the more the air changed—less smoke, more metal; less crowd noise, more the dull pulse of buried machinery.
Their footsteps echoed differently down there.
In the arena, every sound became spectacle.
In the sublevels, every sound became information.
Long Haul had to angle his bucket sideways twice to clear narrow turns. Bonecrusher shoved a warped service door open with one shoulder after the panel refused Scrapper’s override. Mixmaster paused at three junctions to sniff the air through his vents and mutter about chemical residue. Scavenger kept darting ahead, finding old markers scratched into walls, half-buried service numbers, maintenance paths no official map bordered to show.
Hook stayed near the middle, one hand occasionally lifting as if to stop someone before a shift, a low pipe, a patch of weakened floor.
Scrapper led with the map.
The coordinates pulled them deeper.
Sector 9.
Sublevel 47.
By the time they reached the final corridor, the city above felt distant enough to belong to someone else. The hall before them was wide but dark, lined with sealed doors and old conduit. At the far end, a larger entry waited, its surface matte black beneath layers of dust. No insignia. No warning glyphs bright enough to catch the eye. Only a small access panel pulsing faintly, waiting for a code Scrapper had not been given yet.
Then the comlink at his belt buzzed once.
A new line appeared.
[Access granted.]
The door unlocked with a deep mechanical thud.
Slowly, the barrier split open.
Cold air rolled out first, clean and sterile enough to feel unnatural after the smelting yard. Lights flickered awake in sequence, stretching into the dark beyond—rows of dormant workstations, sealed equipment racks, reinforced walls, power couplings, empty frames waiting for purpose.
Farther in, beyond a transparent partition, another chamber sat lower and wider.
A central table.
Wall displays.
Map ports.
Command channels.
The War Room.
No one spoke.
For once, even Scavenger’s hands went still.
Scrapper stepped over the threshold first, optics reflecting the pale light of a place no caste foreman had ever allowed him to imagine entering.
Behind him, the others followed.
Bonecrusher with the first load.
Long Haul with the weight.
Mixmaster with hunger burning in his optics.
Scavenger with his salvaged crates held like treasure.
Hook with the quiet calculation of where the medical station would go.
Six mechs in lime green and purple stood inside the hidden bones of Megatron’s future.
The base was empty.
Waiting.
Scrapper looked across the dark lab, then toward the war room beyond it.
His fingers tightened around the comlink.
“All right,” he said, voice low, rough, and certain. “We start here.”
