The deeper they moved, the quieter everyone got.
Not because the route was safe.
Because Subroute-9 had stopped feeling like a regular mission.
Water dripped from overhead pipes in slow, uneven taps. Dead lights flickered in bad patterns across the tunnel walls. Every few steps, black scrape marks showed up again—sometimes low across the floor, sometimes along the wall, sometimes high enough to mean something had been moving where it shouldn't.
Dain walked at the front without trying to look like a leader.
He just had the best read on the route.
The dark-haired girl stayed to his right, one hand near her blade.
The close-range fighter from the silent duo held the left.
The ranged one stayed a few steps behind with a compact pulse weapon ready.
The steadier clan fighter kept the wounded point-man in motion.
The big fighter dragged his weapon just enough to make the sound annoying.
Dain listened to it all.
Footsteps.
Breathing.
Weight shifts.
Who was tense.
Who was pretending not to be.
The girl glanced at him once. "You got a name?"
"Dain."
"Rin."
The close-range fighter answered without being asked. "Joren."
The ranged one followed. "Sitha."
Dain gave one short nod.
No one looked at the clan pair.
The wounded point-man noticed that and hated it.
A minute later, the tunnel widened into another relay section—smaller than the first chamber, but worse.
A damaged cargo shell was jammed sideways into the wall. One route panel had been torn off completely. Black fluid stained the floor near a snapped restraint line. Chains dragged across the grating and disappeared deeper into the dark.
Sitha crouched first.
"Active tag residue," she said.
Joren checked the broken shell. "Forced open."
Rin looked down the chain marks. "Not random."
The wounded clan point-man snapped, "You all keep saying that."
Dain walked to the broken shell and looked inside.
Empty.
Not smashed empty.
Cleared empty.
That mattered.
He stood back up. "It's taking cargo."
The big fighter frowned. "Who's 'it'?"
Dain looked at the chain marks. "Not one thing."
Nobody liked that answer.
The steadier clan fighter finally spoke. "Sol."
Dain looked at him.
"My name," he said. Then he jerked his head toward the wounded one. "Rhett."
Rhett looked like he would've rather bled out than be introduced like that.
Rin almost smiled.
Then something scraped in the dark ahead.
Everyone froze.
Not a fast sound.
Not a jump.
A drag.
Heavy.
Metallic.
Slow.
Dain raised Umbra Shroud slightly.
The sound came again, then stopped.
No charge followed.
No attack.
That was worse.
Sitha lifted her weapon. "Movement ahead."
"No," Dain said.
She looked at him.
"It wants us to hear it."
That landed hard.
Rin exhaled slowly. "Great."
The route dipped again, curving around a dead support pillar into a lower cargo trench. Dain moved first this time, slower, reading every angle before committing his weight. The others followed tighter than before.
That was the first real sign the formation was changing.
No speeches.
No friendship.
Just less stupidity.
When they turned into the lower trench, they found the body.
A courier.
Pinned under a collapsed route frame, half his uniform torn open, one leg crushed under metal. The black cargo tag on his chest was still blinking weakly.
Alive.
Barely.
Sitha got to him first. "Hey. Stay awake."
His eyes opened halfway. Blood was drying at the corner of his mouth.
"Too late," he whispered.
Rin crouched by the crushed leg. "Can you tell us what hit this route?"
The courier's eyes moved past them toward the dark below.
"Not a route hit," he said.
His voice was shaking.
"It was waiting."
Nobody spoke for a second.
Dain stepped closer. "What was waiting?"
The courier swallowed hard.
"Chains… cargo… walls…" He coughed, then forced the rest out. "They were dragging everything down."
Joren's eyes narrowed. "How many?"
The courier's face twisted. "Didn't count."
Then he grabbed Dain's sleeve with surprising strength.
"Don't let it take the tags."
The blinking light on his chest reflected weakly against the white of Dain's coat.
"Take them where?" Dain asked.
The courier stared into the lower dark.
"To the nest."
Silence.
Even the big fighter had nothing to say to that.
Then the tunnel answered for him.
A deep metallic scream rolled up from somewhere far below them, long and distorted, like chains being pulled across the inside of a broken machine.
Rin's blade came up instantly.
Joren shifted left.
Sitha stood.
Sol pulled Rhett tighter into position.
Even the big fighter stopped acting bored.
Dain looked toward the lower shaft beyond the trench.
Black-red light pulsed faintly from below.
Not route lighting.
Something else.
The courier's grip loosened from Dain's sleeve. "It takes the live ones first," he whispered. "Tagged. Wounded. Anything it can drag…"
Rhett cursed under his breath. "We take him and go."
"No," Sitha said immediately.
Rhett glared at her. "No?"
She pointed at the crushed route around the courier. "He can't move fast. We drag him blind through a broken tunnel while those things close behind us, he dies anyway."
"So we leave him?"
"That's not what I said."
Dain looked at the frame pinning the courier down, then at the descent shaft ahead, then at the others.
They had two problems now.
The route was wrong-grade.
And the live tag made retreat complicated.
Rin read the look on his face first. "You've got an idea."
"A bad one," Dain said.
"Those are usually the ones that work."
Joren crouched beside the broken frame and checked its weight. "Say it."
Dain pointed to Sol and the big fighter. "Lift that frame."
Then to Sitha. "You cut the tag and secure it."
Rhett frowned. "Secure it where?"
Dain tapped the inside strap of his coat. "On me."
Rin caught on first. "You're making yourself the active target."
"If it tracks tags, yes."
The big fighter stared at him. "That's stupid."
"It's faster."
Joren looked at the shaft below. "He's right."
Sitha was already kneeling at the courier's chest. "Do it."
Sol and the big fighter heaved the crushed route frame just enough for the courier to gasp and shift free of the worst pressure. He screamed once through clenched teeth.
Sitha cut the blinking tag loose.
The moment she handed it to Dain, the light on it pulsed harder, like the route itself had recognized a transfer.
Rin looked at the new glow in Dain's hand, then at him. "You better be as good as you act."
"I don't act," Dain said.
He slid the tag into the inner strap beneath his coat.
The light vanished from view.
The courier sagged against the wall, barely conscious now. Sol checked him, then looked up. "He might live if we clear the route fast."
"Might," Rhett muttered.
The metallic scream below came again.
Closer.
The shaft ahead opened into a broken cargo descent where chains hung from snapped supports and disappeared into the dark. Black residue coated the rails. Something had been moving crates—and bodies—through there for a while.
Rin stepped to Dain's right.
Joren moved left.
Sitha centered behind.
Sol held rear-mid with Rhett.
The big fighter tightened in without being told.
There it was again.
Formation.
Dain looked down into the dark shaft, Umbra Shroud in one hand, the stolen active tag against his chest, and finally understood what this mission really was.
Not a route cleanup.
Not a rookie clearance.
A trap nobody worth protecting had bothered to fix.
Good.
That made it simpler.
"From here," he said, "we don't break."
No one argued.
Then they started down.
At the first landing below, they found three more opened cargo shells.
At the second, black fluid smeared across the walls in hand-like streaks.
At the third, something skittered overhead fast enough to disappear before anyone could fire.
And by the time they reached the bottom relay gate, the whole chamber beyond it was breathing with a low black-red pulse that looked almost alive.
Sitha aimed past Dain's shoulder. "Tell me that's just bad lighting."
"It's not," Rin said.
Joren stepped forward half a pace and went still.
Because in the dark ahead, beyond the torn gate and hanging chains, something large shifted its weight.
Not charging.
Waiting.
Dain's hand tightened around Umbra Shroud.
The route had stopped hiding what it was.
And whatever lived in the nest below had already noticed the active tag moving toward it.
