Chapter 16: Patchwork Build

The room beneath the mall had once been part of something too old to belong under any shopping center.

Evan stood in the dead center of it, breathing metal dust and stale ozone, while the floor hummed under his boots like a sleeping animal dreaming of violence. The chamber was wide enough to swallow the food court above it whole. Pillars of black alloy rose in uneven rows, each one ribbed with seams and dormant glyphs. Conveyor tracks ran between them, vanishing into low tunnels plugged with darkness. Half-melted terminals jutted from the walls at crooked angles, screens blank until Evan came too close, then flickering with ghost-pale symbols that made the inside of his skull itch.

The Archive’s normal interface floated cleanly in front of most people. Blue boxes, bright stats, neat progression paths. This place did not speak that language. Here, system text crawled across surfaces like worms under glass. The machinery recognized him, but not like a user. More like a missing part had wandered back into the assembly line.

“I hate this room,” Mara said.

She had planted herself by the entrance tunnel with her shield resting against one hip. The shield was taller than her torso, dented in three places from the mall basilisk’s tail strikes, and she held it with the casual ease of someone who trusted steel more than gravity. Her dark hair was tied back with a strip of torn sleeve. Dried monster blood had crusted along her jaw where she had missed a spot cleaning up.

“You hate most rooms,” Kade said from atop one of the inactive conveyor rails. He sat like a crow, elbows on knees, knives laid across his thighs for inspection. “This one just has better lighting.”

The lighting came from veins in the floor that pulsed every few seconds with dull amber. Each pulse traveled outward from Evan’s feet and faded at the walls. It had started the moment they entered. It had not stopped.

Lena stood near a terminal, hands tucked into the sleeves of her oversized hoodie. The garment had once been pale green. Now it was gray with grime, singed at one hem, and marked by three neat tears where something’s claws had almost found her ribs. Her healing focus—a thin bracelet of braided copper she had looted from a pharmacy dungeon chest—glimmered whenever the room’s pulse passed over her.

“It isn’t lighting,” Lena said quietly. “It’s a response pattern.”

Kade tilted his head. “That sounds worse.”

“It is.”

Evan flexed his right hand. His fingers looked normal until he focused. Then the skin tightened, nails thickening into short black hooks, jaw prickling with phantom pressure as Feral Bite stirred beneath his awareness. Under his jacket, patches of armor plating crawled along his forearms and ribs like overlapping beetle shell. Deep below both, Tremor Sense kept whispering.

Four bodies in the chamber. Mara’s stance, heavy and grounded. Lena’s weight shifting from heel to toe in tiny nervous pulses. Kade’s near-absence, too controlled, too light, heartbeat hidden by trained stillness but not hidden enough. And farther away, behind the walls, something distant moving through pipes. Small. Many-legged. Not close yet.

He exhaled through his nose.

“We need to know what I can actually do before Dominion finds the entrance,” Evan said.

Mara’s expression went flat. “I thought what you could do was bite monsters, turn into a walking junk drawer, and scare everyone with a class screen that looks like a crime scene.”

“That’s the broad version.”

“It’s a useful broad version.”

Evan looked at the dead terminal fifteen feet away. The screen had awakened for him earlier, bleeding a single line of text before going dark again.

ZERO SLOT INSTANCE DETECTED.
Dormant Fabricator Layer accessible.
Trait architecture incomplete.
Awaiting manual configuration.

Manual configuration. The phrase sat in his thoughts like a key with blood on it.

Normal survivors had builds. Classes. Skill slots. Skill trees that handed out options with tidy names and tooltips. Mara had Sentinel nodes that made her harder to move, harder to kill, better at turning herself into a wall between everyone else and disaster. Lena had the White Thread Healer class, though she avoided saying the full name like it was a collar. Kade had something from the Vesper Guild’s assassin line, sharp and private and probably full of backstabs both literal and political.

Evan had no slots.

He had pieces.

Feral Bite from the tunnel hounds. Armor plating from the carapace brute. Tremor Sense from the buried centipede thing that had almost eaten them beneath the collapsed parking level. Each one existed inside him like a stolen organ that didn’t know the others were there. He could trigger them separately, clumsily, always with a lag of instinct and pain. Bite made his jaw ache and his thoughts sharpen toward hunger. Plating slowed him if he overgrew it. Tremor Sense turned the world below his feet into a storm of motion until nausea crept behind his eyes.

Useful, yes. Coherent, no.

And Dominion did not give people time to be incoherent.

They had seen the guild’s scouts in the mall concourse two hours ago. Blue-white cloaks. Clean boots. Crossbows with system runes etched along the limbs. Corporate warband discipline wrapped in heroic branding. The kind of people who smiled at civilians while deciding which of them were worth rations.

One scout had recognized Kade.

That was why they were underground now.

“Tell me what you need,” Lena said.

Evan turned toward her. “Don’t heal me unless I ask.”

Her eyes narrowed. “That is a terrible opening sentence.”

“If the traits react to damage, you patching every tear might interrupt it.”

“Or prevent you from bleeding out because you decided to do basement science with monster organs.”

Kade lifted one knife, checking the edge against the amber glow. “I vote for basement science. It sounds educational.”

Mara shot him a look. “You would.”

“I enjoy supporting Evan’s hobbies.”

“You enjoy watching disasters from a safe angle.”

“That too.”

Evan rolled his shoulders and faced the nearest pillar. It had a dented surface, black metal scarred by age, but when he stepped closer the seams brightened. A circular outline appeared at chest height, then sank inward with a hydraulic sigh. The smell that rolled out was hot copper and old rain.

Inside the pillar rested a rack of suspended objects. Not weapons. Not exactly. Dense, dull-gray rods. Weighted rings. Segmented plates mounted on flexible cables. The chamber had the unmistakable feel of a training room built by someone who considered pain a measurement tool.

Mara’s brows lifted. “Convenient.”

“It opened for him,” Lena murmured.

“Everything creepy opens for him,” Kade said. “It’s becoming a theme.”

Evan reached for one of the rods. The instant his fingers closed around it, text spasmed across his vision—not in the blue of a normal notification, but in dark red characters edged with static.

FABRICATOR LAYER: MANUAL STRESS TRIAL AVAILABLE
Purpose: Identify compatible trait intersections.
Warning: Unsanctioned architecture may cause rejection, mutation, cognitive bleed, or permanent loss of human baseline.

Proceed?

He stared at the final line until the words blurred.

“Evan?” Mara said.

He told them what it said.

Nobody joked.

The hum in the floor filled the silence.

Lena took a step toward him. “Permanent loss of human baseline?”

“System warnings are always dramatic,” Kade said, but the lightness in his voice had thinned.

Mara’s hand tightened on her shield grip. “Not always.”

Evan thought of the people upstairs who had taken bad class evolutions because they were desperate. The man whose arms had become branches after accepting a Dryad-touched Forager mutation. The woman in the parking structure who had screamed while stone grew over her mouth, turning a defensive passive into a coffin. The Archive loved offering power with the fine print written in nerve endings.

His own reflection warped faintly in the pillar’s black alloy. Brown eyes sunk with exhaustion. Stubble. Blood on his collar. A former overnight stocker who knew how to break down pallets, read inventory errors, and find the safest route through aisles during a holiday rush. Not a warrior chosen by destiny. Not an administrator. Not anything the Archive had expected to matter.

Zero Slot.

A broken designation. A garbage class. A missing answer.

Except the machines under the world knew his name.

“If I don’t learn how to make these pieces work together,” he said, “we stay weak in the exact way they expect. Mara tanks until something bigger crushes her. Lena heals until someone chains her. Kade gets dragged back to whatever Vesper wants from him. I bite things and hope my skull doesn’t split open.”

Kade looked away first.

Lena’s lips pressed into a thin line.

Mara held his gaze for a long second, then lowered her shield and planted it upright between them. “Fine. You do the stupid thing. But you do it controlled.”

“That was the plan.”

“No. Your plan was to grab the cursed gym equipment and improvise.”

“That is controlled for him,” Kade said.

Mara ignored him. “You test one interaction at a time. You say what you feel before it gets bad. If Lena says stop, you stop. If I say stop, I make you stop.”

Evan managed half a smile. “Yes, captain.”

“Don’t ‘captain’ me while holding the mutation stick.”

That dragged a small laugh out of Lena despite herself. The sound loosened something in Evan’s chest.

He accepted the prompt.

The rod in his hand unfolded.

Segments slid apart with crisp clicks, lengthening into a staff as heavy as a crowbar and twice as ugly. Amber lines raced along its surface, then dimmed. Across the room, three floor panels opened. Training constructs rose from below.

They were skeletal things made of jointed metal and dull ceramic plates, roughly human-shaped but wrong in all proportions. Long arms. No heads. Cores glowing faintly behind slatted ribs. They unfolded from crouches as if waking from prayer, then turned toward Evan in perfect unison.

Kade slipped off the rail, knives in hand. “Those are not punching bags.”

“Stay back,” Evan said.

The first construct lunged.

It crossed the distance faster than he expected, feet striking the floor with sharp metallic cracks. Tremor Sense flared before his eyes could track it. The impact pattern rushed into him through his soles: weight transfer, hip rotation, a right-arm strike aimed at his ribs.

Evan moved left.

Not enough.

The construct’s fist clipped his side. Pain burst white under his jacket. Armor plating surged instinctively, overlapping plates snapping into place across his ribs a heartbeat after impact. Too late to prevent the bruise, soon enough to stop the second hit from cracking bone.

Mara swore.

Evan gritted his teeth and swung the staff. It struck the construct’s forearm with a clang that jarred his wrist numb. Feral Bite rose, completely unhelpful at staff range, flooding his mouth with saliva and his jaw with pressure.

Not separate, he thought, backing away as the second construct circled. Stop firing like separate alarms.

The first construct attacked again. This time he leaned into Tremor Sense instead of flinching from it. The floor told him the strike before the construct finished making it. Left foot loading. Shoulder dipping. Low sweep.

He jumped.

The sweep passed under his boots. In midair, armor plating dragged at his torso, shifting his balance badly. He landed heavy, knees bending too deep. The second construct’s elbow hammered into his back.

Plating caught it.

The force drove him to one knee anyway.

“Evan!” Lena called.

“I’m good,” he lied, and rolled before the third construct’s foot crushed the spot where his hand had been.

Kade paced along the edge of the fight, eyes sharp. “Your armor is reacting after commitment. It’s making you late.”

“Noticed,” Evan snapped.

“Bite is doing nothing.”

“Also noticed.”

“Have you tried biting the staff?”

“Kade,” Mara growled.

Evan ducked a punch, felt the air move over his hair, and slammed the staff into the construct’s knee. The joint buckled. Its weight changed. Tremor Sense painted the imbalance in exquisite detail, a crackling map of force traveling through metal limbs into the floor.

A thought hit him.

Not a plan. A warehouse instinct.

When a pallet leaned wrong, you didn’t push at random. You found where the weight wanted to go and helped it fail.

The construct tried to recover. Evan dropped the staff, stepped inside its reach, and let Feral Bite take his jaw.

His teeth lengthened. His mouth burned. The world narrowed to the exposed glow behind the construct’s rib slats. Armor plating crawled up his neck and along his cheekbones, not as defense but as bracing. Tremor Sense fed him the machine’s vibration through the floor, through his shins, through the hand he planted against its chest.

He bit into the core housing.

Metal screamed between his teeth.

The taste was impossible—iron, battery acid, hot dust, and something like raw data fizzing over his tongue. His jaw should have broken. Instead, the plating along his skull tightened, distributing force down his neck and shoulders. Tremor Sense locked onto the core’s rhythm, each pulse showing him when to crush, when to twist.

He wrenched sideways.

The core tore free in a spray of amber sparks.

The construct collapsed.

For one stunned second, nobody moved.

Then the remaining two constructs accelerated.

“That,” Kade said, “was disgusting and effective.”

Evan spat the ruined core onto the floor. His gums bled. His jaw throbbed, but beneath the pain something had aligned. Not perfectly. Not safely. But for that one bite, the three traits had stopped fighting each other.

A red-black notification flickered at the edge of his vision, then vanished before he could read it.

“Again,” he muttered.

Mara heard him. “You are not seriously—”

The second construct slammed into him.

This time the armor came before the hit landed.

Not everywhere. Not the clumsy full shell that slowed his arms. Plates hardened across his left shoulder and outer forearm only, angled toward the incoming force. Tremor Sense predicted the vector. His body answered. The construct’s blow skidded off with a shriek, driving him back but not breaking stance.

Evan’s grin tasted like blood.
