Chapter 189: Fifty-One Minutes of Noise
They bolted the decoy to the shelf with the mounting collar and two anchor pins. At 00:48, Bram started it.
Jin heard the first impact from the station doorway two hundred and forty meters away, which was the entire point.
It was an ugly sound. The counterweight came around and hammered the bedrock, released, then struck again. Every rotation differed slightly as the degraded bearings protested under a load they had never been designed to carry. There was no stable rhythm, only a heavy piece of metal hitting stone at irregular intervals.
Under Jin’s palm, Glitch became utterly motionless.
"Report," Mira called from inside.
"Give me a minute."
The first Tunnelmaw turned at 00:51.
Jin felt a line drifting east beneath the station stop, hold for perhaps four seconds, then settle onto a new heading pointed away from them and toward the shelf.
"One turned."
A second came from the south, cutting across the first. Over the next six minutes, five more followed.
"They’re going," Jin said. "Most of them. One line northwest hasn’t moved, and two deeper ones haven’t reacted, but the main concentration is heading northeast."
Bram and Kellan returned at 01:04, filthy and breathing hard. Bram sat against the wall and closed his eyes without saying anything.
The motor ran for fifty-one minutes.
Jin listened to it die in stages. The impacts slowed and lost what little rhythm they possessed. Something inside the housing gave way, changing the sound to a grinding rattle, and at 01:39 a final crack passed through the bedrock before the shelf fell quiet.
He tracked the aftermath with more attention than he had given anything all day.
Nothing came back.
The colony’s largest concentration had committed northeast. When the noise stopped, the Tunnelmaws kept going, slowed, then began drifting around the site of the last disturbance, investigating bedrock that was no longer doing anything interesting.
"They’re staying out there," Jin said at last. "Most of them. Four or five are still scattered through the sector, so the original route is still unsafe."
"But not here," Mira said.
"Not here."
She released a long breath. "Then everyone sleeps. Astor, set the rotation."
"Two-hour watches, two awake. The generator stays off."
"For the whole night?" Kellan asked.
"For the whole night," Jin said. "I’d rather be cold and boring."
The rest of the night was cold and boring, which Jin counted as an unqualified success.
He took the 02:00 watch because it was the worst remaining slot and because he had assigned it. Bram joined him at 04:00 without being asked and did not mention that he had also taken the watch before the decoy run.
They overlapped for about twenty minutes during the change.
"You should’ve made someone else take one of those," Jin said.
"Voss is finished. Pell is awake every hour with Halden anyway." Bram shrugged in the darkness. "It’s two hours."
They watched the sealed entrance in silence.
"You gave good orders," Bram said after a while.
"Some of them."
"You put the west flank on me, gave timing to Voss, and kept Pell inside. That’s what I would’ve done if I’d known what was under us, which I didn’t." Bram kept his eyes on the door. "So I followed. Everyone’s alive."
"That’s it?"
"What else is there?"
Jin considered the question and found nothing else.
"If we’re put on the same team again," Bram said, "I’ll do the same thing. That’s all."
He returned to watching the door. The conversation ended there, and Jin preferred it to almost every conversation he had held at Meridian.
Glitch slept for nine hours.
He spent them in a corner of the central room with his chin across Jin’s boot and barely moved. Nia checked him twice and found nothing worse than what she had reported the day before.
"He isn’t injured. He’s spent."
"Yeah."
"Whatever he does—the ground thing—how long was he doing it?"
"Since about ten yesterday morning, on and off."
Nia did the arithmetic and pulled a face. "Then he needs at least one full day. Two would be better before you ask anything serious of him."
Glitch was still Rank 1, 4-Star. Jin checked once out of old reflex, but the number had not moved. Whatever the last twenty-six hours had cost Glitch’s body, exhaustion alone had not converted into advancement.
The bond still held a strung-tight quality, as if Glitch had reached the end of a length of rope. Harden had been maintained four times in a real fight. Tremor Sense had stayed open on and off across most of a day, through broken terrain and under pressure.
Close. Not there.
Extraction arrived at 13:52 in two armored transports. Instructor Odgar entered the dark station, counted the four students standing and the one who could not, then looked up at the dead lights.
"Any of you going to tell me why my generator is off?"
"I turned it off," Jin said.
"Right." Odgar looked toward Mira. "Halden. Can you walk?"
"No."
"Then don’t."
The debrief began at 17:00 in a hall containing all eleven teams. Team 7’s portion lasted nineteen minutes, the longest of the day.
Odgar read the failures first.
"Team Seven. Sensor route incomplete—two of seven units uninspected. Communication pack lost. Academy equipment cannibalized: antenna positioner assembly, counterweight plate, and mounting hardware, all destroyed. Team did not reach the scheduled extraction point."
He let the words settle.
"Deductions across route completion, equipment accountability, and objective delivery."
Then he turned the page.
"Every student alive. Every contracted beast alive with no irreversible injury." Odgar looked up. "That isn’t the standard. That’s the floor. Here’s what earned them marks."
He went through the record.
"Astor identified that a restored sensor was reporting a clear surface while its seismic and depth channels were dead. He said so before the breach, labelled his confidence correctly, and was right."
"The team recognized a chain reaction instead of a single threat: Tunnelmaw expansion displacing Stonehorns, Stonehorns drawing Carrion Hounds, and three Rank-1 populations outside their recorded zones. That’s a sector-scale read. It is what the report needed."
"Halden pushed Pell clear of a charging grazer and took the impact herself. She then provided surface information for six hours from the ground and from a chair. That is in the record, and it is why her team knew where it was going."
Mira sat in the front row with her leg braced and did not react.
"Pell stabilized a serious leg injury under field conditions. She checked circulation and sensation, splinted conservatively, and confirmed Halden could be moved without worsening the injury. Her initial hesitation is noted, and it is not a deduction. Freezing once, then doing your job properly for the next twenty hours, is not failure. It is what the assessment is for."
Nia went scarlet and stared at her knees.
"Rook held an assigned position without deviation throughout the crisis and carried the improvised device two hundred and forty meters through active tunnelling. Voss chased nothing after the first hour, which is the single hardest correction any Fifth Class student makes."
Kellan made a small sound.
"And the decoy." Odgar closed the slate. "Team Seven correctly identified that their auxiliary generator was drawing the colony, shut it down, and relocated the vibration to a bedrock shelf two hundred and forty meters away using a positioner motor and counterweight. The colony converged on the decoy. No further contact occurred at the station."
He looked across the hall.
"They solved a Rank-1 mass convergence without fighting it. I’d like every one of you to think about that, because most of you would have barricaded a door and lost a beast."
