Ghost’s shot cracked across the ravine and the console operator folded over the rail.
Yuki dropped her hand and Specter moved.
They slid down wet rock into the utility spine while Meridian rounds stitched sparks across the concrete above them. Rusk’s team scattered for new cover. Vale’s demolition crew kept planting canisters instead of shooting, disciplined enough to trust others with the killing.
“East flank, ten meters!” Santos yelled.
Yuki fired on the move, forcing two troopers behind a broken wall. Doc dragged Mercer between cover points by his restraints while Chen and Okoro stayed tight to the inner edge with the token case.
Rusk disappeared into a narrow service cut in the spine wall.
“There!” Ghost pointed with his rifle muzzle. “She’s heading lower levels.”
Mercer twisted against his ties. “Service Cut B loops to gate chamber. Fastest route.”
Yuki looked once at the route overlay on her HUD. No time for a full confirm. Vale’s charges were arming. Rusk had active relay keys.
“Take us,” she said.
Ghost shot her a hard look.
Yuki made the call anyway.
“Move on Mercer.”
They pushed into Service Cut B single file.
The tunnel narrowed immediately, old concrete sweating with moisture, maintenance lights flickering weak yellow. It curved down in tight switchbacks, too tight for Ghost’s favorite sight lines.
Doc kept Mercer ahead of her at muzzle point. “If this is a trick, I treat your pain like a suggestion.”
Mercer kept walking. “You want Rusk? This gets you there.”
Chen breathed hard, shoulder bandage soaked through. “ATLAS, tunnel status.”
Static answered first. Then: “Partial map only. Legacy branch. No active monitoring.”
No active monitoring should have ended the argument. It didn’t.
Yuki heard the warning and chose speed over certainty.
At the third bend, the floor changed under her boots.
Not sound. Texture. Smooth plates under mud.
“Stop—” she started.
The first harmonic mine triggered.
It did not explode like a standard charge. It screamed.
A focused sonic blast slammed through the corridor, invisible and crushing, knocking everyone off their feet. Yuki’s prosthetic seized as the frequency hit, arm locked straight out while her organic shoulder lit with pain.
Second mine triggered before anyone could recover.
Concrete burst from the sidewall. Shrapnel and root splinters tore down the passage.
Okoro took the hit.
She went down with a sharp, cut-off sound as a shard punched through her thigh and into the wall behind her. The token case flew from her hands and skidded into dark water.
Doc crawled to her instantly. “Pressure wound! Santos, light!”
Santos snapped a flare strip and slapped it to the wall. Orange light flooded the tunnel, showing blood running fast down Okoro’s leg and pooling around her boot.
Ghost dragged Chen clear of a collapsing ceiling panel. Mercer used the chaos to bolt.
He made three steps before Yuki’s prosthetic hand caught his harness and slammed him face-first into the floor.
“You lied,” she said.
Mercer coughed blood and laughed anyway. “I gave you a route. Didn’t say it was safe.”
A red indicator blinked behind his ear.
Chen saw it and cursed. “Tracer implant. He’s beaconing our position.”
Yuki ripped the implant free with two fingers and crushed it.
Too late. Rounds hit the tunnel mouth behind them.
Vale’s people had followed the beacon straight in.
“Contact rear!” Ghost shouted.
He took position behind a fallen beam and started controlled fire down the corridor. Santos joined him, limping but steady, creating a wall of bullets that bought Doc seconds.
Doc packed Okoro’s wound with clot foam and wrapped a compression sleeve around the thigh. “Shrapnel is lodged near femoral track. She moves wrong, she bleeds out.”
Okoro’s face had gone gray. “Token,” she whispered.
Yuki scanned the water channel and found the shock case half-submerged between two pipe supports. She lunged, grabbed it, and felt her calf armor rip wider on exposed rebar.
She came back with the case.
The front latch was cracked.
“Is it intact?” Chen asked.
Yuki opened it just enough to check.
The harmonic token still sat in its cradle, but a fracture line ran through one edge, glowing unevenly.
“Damaged,” Okoro said through clenched teeth. “Might still validate if resonance stays stable. Might not.”
Might not.
Yuki shoved the case into Chen’s pack.
ATLAS broke through static with urgent clipping.
“Warning. Phase-lance charge cluster armed in archive sublevels. Detonation in four minutes.”
Santos looked up from her firing lane. “We are in archive sublevels.”
“Exactly.”
Yuki ran options fast.
Forward route unknown and mined.
Rear route full of Meridian rifles.
Ceiling unstable.
One map possibility remained: vertical drainage shaft thirty meters ahead, shown in faint lines on Chen’s recovered overlay.
“Push forward,” Yuki ordered. “Ghost and Santos bound by twos. Doc with Okoro center. Chen with me. Mercer comes too.”
“Why keep him?” Santos demanded.
“Because he still knows routes.”
Ghost fired two quick shots, then moved. Santos covered. They leapfrogged down the corridor while Yuki hauled Mercer by his collar and Chen hobbled beside her, one arm pressed to his shoulder wound.
Doc and Okoro moved slow, every step a calculation.
Meridian rounds chipped concrete inches from Doc’s back. She did not break rhythm.
“Keep pressure on that sleeve,” she told Okoro. “Talk to me.”
Okoro panted through pain. “Still here. Not dead. Annoyed.”
“Good. Stay annoyed.”
They reached the shaft as the floor shuddered from a distant pre-blast pulse.
A rusted grate blocked the opening.
Yuki tore it free with the prosthetic despite servo lag. Ghost popped a smoke canister into the corridor behind them.
“Climb!”
Santos went first despite the leg wound, hauling herself up iron rungs. Chen followed. Ghost shoved Mercer toward the ladder and put a round through his calf when he tried to pivot.
“No running now,” Ghost said.
Doc clipped Okoro into a rescue sling and Yuki braced below while they hauled together.
The first phase-lance charge detonated.
The blast came as a deep concussive thump that turned the air solid for a second. Tunnel lights died. Dust and hot fragments shot up the shaft like a furnace breath.
Second charge blew before they were halfway.
The ladder ripped free from one wall anchor. Everyone swung hard. Chen almost lost grip and only stayed on because Santos grabbed his harness with one hand while hanging by the other.
“Don’t die on me!” she yelled.
“Not planning to!”
They reached the top lip and spilled into a root cave that opened to the forest.
Behind them, the shaft collapsed in sections with grinding thunder.
The archive sublevel route was gone.
Yuki turned in time to see the far hillside sag as internal supports failed. White light from old corridors flickered through cracks, then vanished under falling earth.
Prime seed vault, transit chamber, maybe half the files they had not copied—buried.
Chen stared at the collapse, face blank with shock. “We lost it. We lost most of it.”
Yuki did not answer because he was right.
Her mistake had cost them time, blood, and evidence.
ATLAS’s voice came through weakly from below ground.
“Core integrity compromised. Remaining operational window: unknown. Data mirror in your possession remains viable. Prioritize external transmission.”
Then silence.
Ghost checked perimeter and found Wardens at the tree line again, two of them wounded, amber fluid staining bark armor. They made no move to attack.
One pointed deeper east, away from the collapse, toward a rocky ridge with narrow slots that could hide a team.
“They’re giving us shelter,” Okoro whispered.
“Or funneling,” Santos said.
Yuki looked at her bleeding squad, at the ruined hillside, at the smoke rising where the archive had stood for decades.
Funnel or shelter, they could not stay exposed.
“Take it,” she said.
They moved under Warden guidance into a split in the ridge that opened to a dry cavern.
Inside, three Wardens waited near a mineral wall where bioluminescent veins drew crude maps in moving light. One of the wounded figures pressed a palm to the stone and a route diagram bloomed: switchback ravines, collapsed service lines, a red-marked zone around the gate chamber.
Okoro stared through pain and translated between breaths. “They’re warning of harmonic dead spots. Mercer’s route probably passed through one. That’s what armed the mines when we entered.”
Yuki looked at Mercer. “You knew that?”
Mercer shrugged with one shoulder. “I knew there were traps. Didn’t know trigger frequency. Same result.”
Ghost stepped in close enough that Mercer could smell him. “Not same result if you wanted us alive.”
The lead Warden touched Yuki’s prosthetic, then the red zone on the wall map, then drew a slash across one narrow corridor.
“No-go lane,” Chen said. “That corridor is structurally gone after the blast.”
ATLAS crackled back online with a weak but readable packet.
“Supplementary map upload available. Source: Warden relay mesh. Warning: relay signal degrades in twelve minutes.”
Chen pulled the packet and merged it with his terrain overlay. New paths appeared, ugly but usable, crossing open stone where cover was poor.
“This gives us one shot route,” he said. “Fast path is exposed. Safe path is too long. We choose exposed.”
Doc didn’t look up from Okoro as she answered, “Everything is exposed when you carry a casualty.”
The wounded Warden by the wall made a low click, then pushed a small bundle toward Doc. Inside were strips of fibrous material soaked in amber gel.
Doc scanned one strip. “Biopolymer sealant. Coag factor high.” She gave the Warden a brief nod before applying it around Okoro’s wound edge. “I hate how often alien medicine works better than ours.”
Santos watched the exchange and muttered, “Add it to the list of things command lied about.”
Yuki held her palm against the map wall and felt the bioluminescent lines pulse under her skin, tracking with the same frequency in her arm. The Wardens weren’t giving charity. They were giving coordinates to the one human they had tagged as interface and expecting her to finish the job humans started.
Doc got Okoro onto a flat stone and cut the pant leg away. The wound was ugly: deep puncture, secondary tearing, shrapnel fragment visible but too close to artery for field extraction.
“She doesn’t walk far,” Doc said. “Not tonight.”
Santos slumped against the wall and finally let herself shake for three breaths before she forced it down.
Chen unpacked the token case with careful hands and ran a diagnostic.
“Fracture is propagating,” he said. “If resonance spikes, the token splits and we lose gate ignition.”
Ghost dumped Mercer at Yuki’s feet.
Mercer’s face was coated in mud and blood, but he still managed a crooked smile. “You should’ve shot me when you had the chance.”
Yuki crouched in front of him. “Where did Rusk go.”
“East transfer line.”
“Where does it end?”
“Dormant gate chamber. Same place you’re going.”
He coughed and grinned wider. “Difference is she’ll get there first.”
Yuki grabbed his collar harder. “How many with her?”
“Eight when I last saw. Plus Vale’s demolition pair.”
Ghost leaned against the cave wall, watching Mercer with the calm patience of a sniper selecting distance.
“He gave us a trapped corridor,” Ghost said. “He’ll do it again.”
Yuki knew he was right.
She also knew they still needed route intelligence and terrain timings.
She made the same gamble twice.
“Mercer walks with us,” she said.
Santos pushed off the wall so fast her bad leg nearly buckled. “After this? Seriously?”
“He gives one bad turn and he dies.”
Mercer lifted his head. “I can get you to the gate before Rusk arms full lock.”
Doc looked up from Okoro’s wound with open disbelief. “You’re trusting him again?”
Yuki did not blink.
“I’m using him.”
ATLAS returned on low-power burst.
“Urgent. Remaining gate infrastructure unstable. Estimated lock window: forty-one minutes.”
Forty-one minutes to cross hostile ground with one critical casualty, one damaged token, one bleeding analyst, one limping riflewoman, and one prisoner who had already sold them once.
Yuki stood and checked every face.
Ghost: controlled, ready.
Santos: furious, still in.
Doc: exhausted, focused.
Chen: pale, stubborn.
Okoro: sweating, conscious, barely.
Mercer: opportunistic predator waiting for an opening.
She hated the numbers and moved anyway.
“Pack up,” she said. “We go now.”
Doc tightened Okoro’s tourniquet and whispered, “You stay with me. No heroics.”
Okoro nodded once, eyes half-lidded.
Yuki stepped to the cave mouth and looked at the black ridge lines ahead.
Rain started, thin and cold.
She turned back to Okoro. “Can you walk?”
Okoro stared at her for a long second.
She didn’t answer.
