Chen's signal readings got stranger the deeper they went.
He walked with his array held out like a dowsing rod, adjusting frequency filters and muttering corrections to himself, occasionally stopping mid-stride to kneel and take a surface reading from the root-mat floor. The others worked around him, Ghost taking point, Santos at rear, Yuki in center where she could read the whole corridor, and nobody told him to hurry because he was finding the thing Parr had spent eleven years burying in non-priority data and everybody understood that was worth a minute here and there.
"Okay, so," Chen said, crouching over a floor reading. "The pulse rate is increasing."
"Meaning we're closer," Yuki said.
"Meaning we're closer and it's responding to something." He ran another sweep. "The pulses were nine-point-four seconds apart at the corridor entrance. Now they're at seven-point-one." He looked up. "The interval's been shrinking since we crossed the two-kilometer mark. That started about twenty minutes ago."
"When did we cross two kilometers?"
"About twenty minutes ago."
Okoro said, from where she walked with careful deliberateness behind Doc, "It noticed us."
Nobody argued.
The corridor opened wider where two massive root systems had converged over centuries into a natural archway, which Yuki had noted on mission twenty-three as a good position for a cover break. Today she kept moving through it without stopping, reading the fauna paralleling them in the undergrowth. Still escorting. Still not threatening. The corridor's alpha predator, a six-limbed ambush specialist that hunted here in pairs, should have had a cached kill somewhere in this zone at this time of Haven's morning cycle. There was no sign of it.
Something had moved it off its territory.
"Ghost," she said quietly.
"Already thinking it," he said. "Predator cleared the corridor. Scavenging species running alongside us rather than away. The air compound Doc flagged is stronger here."
"What's your assessment?"
He was quiet for long enough to mean he was choosing words with care, which Ghost rarely did by accident.
"Something underground is managing this environment," he said. "Not like a human would. No tool evidence, no physical modification. Just chemistry and signal. The fauna isn't afraid of the source. It's deferring to it."
"There's a difference?"
"Fear and deference look the same at distance. Up close they don't." He glanced back at her briefly. "Fear has an edge. Like Haven fauna when we first ran extraction. Defensive aggression, territory pressure, the constant calculation of threat. What I'm reading now is quieter. Like this is the normal state and we've just stepped into it."
Yuki processed that. "So Haven fauna defers to what's underground. Has always deferred."
"I think so. Yeah."
"And Reapers have been running missions through this corridor for eleven years and nobody noticed."
Ghost said, "Reapers weren't looking for it. We were looking for threats. Fauna that wasn't attacking us wasn't a threat." A pause. "We were very good at not looking at what we weren't supposed to look at."
The quiet landed between them for a few paces.
Yuki had thirty-nine extractions on record. Thirty-nine missions through wormholes onto alien worlds, with orders to extract resources and eliminate threats and not think too hard about the things that hadn't been classified as threats. She was very good at her job.
The thing about being very good at your job was that it made it easy to not notice what the job was actually doing.
"Cole," she said.
Cole came forward from his position between Chen and Doc.
"Your tablet has been in your pocket for an hour," she said. "That's the longest you've gone without making an entry since we landed."
Cole's expression didn't change. "Mission conditions have been relatively stable."
"What's the last entry you made?"
"Fauna observation at the corridor entrance." He said it easily. Practiced ease. "Environmental conditions, squad formation, directional heading."
"Directional heading," Ghost repeated, not quite a question.
"Standard observer data," Cole said.
Yuki looked at him. She'd worked with informers in three previous missions, soldiers who reported to command while running with their squads, sometimes out of loyalty, sometimes out of fear, sometimes because someone they loved was being held over their head. They all had the same tell: the ease. Not the nervousness of someone who might be caught, but the ease of someone who'd already arranged for it not to matter if they were caught.
Cole had the ease.
"Copy," she said, and turned back to the corridor.
She'd let it go. For now. Cole reporting their directional heading didn't tell Parr anything he didn't already know from the mission parameters. The north approach led one direction. What she needed to know was when Cole stopped making logged entries and started making ones he intended to hide.
That would tell her when he thought he had something worth hiding.

Midday on Haven was a different light: the gas giant's reflected glow shifting from blue-gray to something amber, the canopy filtering it into columns of warm dust-heavy illumination that moved with the slow breathing of the root systems. Chen had told her once that the optical effect was caused by spore-release cycles timed to Haven's light maximum. She'd filed it as mission-irrelevant data and then kept noticing it on every subsequent mission because apparently some data was irrelevant until it wasn't.
Santos dropped back to walk beside Yuki during the third rest break.
She didn't say anything for a minute. She didn't need to. The fact that she'd dropped back was the thing itself.
"What's bothering you," Yuki said.
"Cole's not just logging observations." Santos kept her voice below the ambient wind-sound in the canopy. "He's doing equipment checks every thirty minutes. On a portable comms unit he said was in blackout."
Yuki hadn't seen that. She'd been watching his tablet. "You're sure?"
"He's running a diagnostic cycle. I've seen field comms diagnostics enough times to recognize the hand movement." Santos didn't look at Cole, who was forty meters up the corridor with Chen and Doc. "He's running signal tests. Looking for a frequency that works in this environment."
"Haven's EM interference suppresses standard comms until you get above canopy level."
"Which means if he finds a frequency that works here, he found it because someone specifically tuned a unit to cut through Haven's natural interference." Santos paused. "That's not standard observer equipment."
Yuki looked at the canopy.
If Cole had a unit tuned to cut through Haven's interference, Parr had given it to him specifically for this mission. Which meant Parr had expected them to go deep enough into the corridor that standard comms would fail, and had planned accordingly.
Which meant Parr expected them to reach the formation.
"He knew we'd find it," Yuki said.
"He always knew. The question is what he wants us to do when we do." Santos finally looked forward, toward where Cole walked between Chen and Doc like a man who was comfortable being surrounded by people who didn't fully trust him. "Do you think he knows he's made?"
"I think he knows we're watching him. I don't think he thinks it matters." Yuki considered. "He's right that it doesn't matter in the short term. If he gets a signal out, it gets out. We can't stop the physics."
"So what's the play?"
Yuki had been turning it since Cole pocketed the tablet an hour ago. The geometry of the trap inside the trap.
Parr needed them to find the formation and die with the knowledge. Cole was the timing mechanism, the signal that would bring Continuity forces to the right location at the right moment. If Cole's signal reached Parr, Continuity teams would arrive with enough force to sweep the corridor and eliminate Specter and whatever they'd found.
The counter was speed and documentation.
"Chen needs to record everything from the moment we reach the formation," she said. "Full data capture: electromagnetic readings, structural survey, physical samples if it's safe to take them. Everything that can be transmitted externally."
"And then we transmit it before Cole can signal Parr."
"We transmit it instead of Cole signaling Parr." She looked at Santos. "Harrison needs to be ready for an outgoing burst on the same civilian network Chen used for the directive package. If we can get above canopy level or find a gap in Haven's EM field, we push everything Chen records in one burst."
"And Parr gets to read about his classified formation in a public archive."
"That's the theory."
Santos made the sound she made when a plan had the right shape but an uncertain number of moving parts. "What if Cole signals before we reach it?"
"Then we improvise," Yuki said. "That's also part of the plan."
"The part where we improvise is not usually considered the plan, boss."
"It is when we write it down first."
Santos almost smiled. The most she'd done since Haven. "Tell me something. When this is over, assuming we're alive." She paused like she was deciding whether to say the next part. "Viktor. You think he knew it would end like that?"
Yuki thought about Viktor's voice on the packet. *Tell little wolf the old bastard is still breathing.* The warmth in it despite everything. The deliberate warmth, from a man who'd spent a career hiding warmth under military correctness because he thought it made things easier for the soldiers who trusted him.
"I think he knew the odds," she said. "And he told us what mattered anyway."
Santos nodded. Left it there.
They caught up to the forward group at the three-kilometer marker, where Chen had stopped and was standing very still with his array held level.
"I need everyone to look at this," he said.
He turned the display toward them.
The signal pulse had hit four-point-three seconds between beats. The frequency had also shifted, a half-step up the spectrum that Chen's equipment wasn't designed to read but was reading anyway, in the same way you could hear a sound that was technically above your range if it was loud enough.
And overlaid on the pulse readings: a second pattern. Irregular. Not random, irregular in the way that prime number sequences were irregular, with mathematical structure underneath the apparent chaos.
"That's a response pattern," Chen said. "The primary pulse is the source, the formation, whatever it is. This secondary pattern started four minutes ago." He looked at them. "Something on Haven's surface is responding to it."
"Fauna?" Ghost asked.
"Root network," Okoro said, before Chen could answer. She'd been running her own scanner. "The root systems in this section are generating electrical activity I haven't recorded before. The secondary pattern in Chen's reading, it's the root network. It's answering."
Silence.
"Answering what?" Santos said.
Nobody answered that.
But the deeper they walked, the shorter the pulse interval got, and the louder the root network's answer became in Chen's readouts, and the question that nobody said out loud was whether Haven had been having this conversation long before any human stepped through a wormhole and started calling this world a resource extraction target.
And if it had, what exactly had it been saying?
