They found the Wardens at the three-and-a-half-kilometer mark, in a root cavity that smelled of their chemistry and something else. Something antiseptic, human-manufactured.
Five Wardens. Alive. Three in defensive posture at the cavity entrance, two deeper in. One of those moved with the careful deliberateness of an injured Warden; the other was motionless in a way that said sleeping or dead, and among Wardens those were hard to distinguish at range.
And with them: a man.
He was in Reaper-adjacent gear, a standard extraction suit modified with patches Yuki didn't recognize from any active squad. He was sitting against the root wall eating from a ration pack and reading from a handheld terminal with the focused calm of someone who'd been in worse places and had come to terms with this one.
He looked up when Ghost's rifle moved to him.
"Don't," he said, voice even. "I've been here long enough that your body heat isn't enough to startle them, but a rifle discharge will be."
The Wardens had tracked Specter's entry with the slow, deliberate attention of their kind. They were not threatening. They were watching.
"Who are you," Yuki said.
"Kowalski. Specialist Tomasz Kowalski. Technical branch, CENTCOM data systems." He set down the ration pack. "I was on Haven running a monitoring assignment when the orbital strike happened. Node chamber went dark, wormhole closed. I've been embedded with this group for eight days."
Eight days. The orbital strike had been eight days ago.
Yuki assessed him while he talked. Mid-thirties, lean in the way that field work produced, not gym-lean, work-lean. Calluses in the right places. The terminal he'd been reading had active files on it, which meant he'd been working, not just surviving.
"What monitoring assignment?" she asked.
"Subsurface electromagnetic survey. Classified to Director Parr's office." He said it flatly, no attempt to soften it. "I know who you are. I know why you're here. I was watching the node corridor signals before the strike happened."
"You were surveying the formation."
"I was surveying the formation's output characteristics for the last six months." He looked at her steadily. "I have six months of data on what that thing is doing underground. And I'm going to tell you that you're being set up to walk into it and not walk back out."
Ghost did not lower his rifle.
Santos said, "Give us one reason he's not another Cole."
Kowalski looked at Cole, who'd followed Specter into the cavity and was now standing near the entrance with his expression carefully neutral.
"You brought a Continuity observer," Kowalski said. "That's Parr's kill switch, the person who signals your position when you reach the formation so the sweep team can move in." He looked at Cole directly. "You're running a modified frequency comms unit. I saw you do a signal test forty minutes ago. You found the carrier wave Parr tuned for Haven interference suppression, which means you know the frequency, which means you've already confirmed you can reach him when you're above the EM shadow."
Cole's expression didn't change.
"Specialist Kowalski," Cole said pleasantly, "you've been on Haven for eight days with limited resource access. Your threat assessment may not account for current mission parameters."
"My threat assessment accounts for the fact that Parr sent me here to characterize the formation so he could classify it and lock it down permanently," Kowalski said. "When the strike happened, I wasn't collateral damage. I was a loose end he decided not to spend another orbital asset on."
Yuki kept reading him. The story tracked: a technical specialist running a classified survey, no combat profile, no obvious weapon on him, using the Wardens for cover rather than trying to reach the corridor by himself. That was either genuine field-sense or a very good cover.
"The Wardens let you stay with them," she said.
"They let me stay the first night because I wasn't a threat. They kept me after because I was useful." He indicated the terminal. "I've been running electromagnetic readings for them. Helping them understand what the signal outputs mean." He paused. "They communicate through chemical signaling, you know. But they understand numerical data if you display it correctly. We've been having a slow conversation about what's underground for eight days."
Doc had been watching the injured Warden in the back of the cavity. She moved toward it with her medical scanner, not asking permission, just doing.
The Warden didn't object. That was its own kind of data.
"What does your data show?" Chen asked. He'd been visibly vibrating since Kowalski mentioned six months of formation readings.
"I'll share it," Kowalski said. "If you share your plan."
It was the reasonable trade. That was the thing Yuki noticed: every element of what Kowalski had said was reasonable. The data. The offer. The identification of Cole. The framing of his own role as someone who'd been set up, not someone who was setting them up.
Reasonable was a tool.
But reasonable was also sometimes just accurate.
She looked at the Wardens, three at the entrance, tracking this conversation with their patient, inhuman attention. They'd kept him. They'd let Specter in without hostility. Haven's own chemistry had cleared the corridor for them.
She made the call.
"We're trying to reach the formation before Parr's team arrives," she said. "Chen records everything he can in the time we have. We transmit on a civilian relay before Cole can signal Parr's sweep team. You share your data now, before we reach the formation, not after, and you come with us as a resource."
Kowalski looked at her. Then at Cole. Then back.
"Copy that," he said.
He handed Chen the terminal.
---
They spent an hour in the cavity.
It should have been thirty minutes. Chen dragged it to an hour because Kowalski's data was better than anything he'd expected: six months of continuous formation monitoring, pulse intervals, frequency analyses, three-dimensional modeling of the subsurface void based on echo-sounding that Kowalski had apparently done by himself with equipment he'd modified from a standard survey kit.
Doc spent the same hour on the injured Warden. It had taken a projectile wound to its secondary arm cluster, the same kind of wound they'd seen on the dead Wardens in the burn zone. Doc worked with the specific focus of someone performing surgery in a foreign language, reading anatomy on the fly, making inferences from what she knew about analogous biological functions.
The Warden let her. More than that: it cooperated with the deliberate patience of something that understood what was happening and was choosing to trust it.
Yuki stood at the cavity entrance with Ghost and watched the corridor.
Haven's fauna was still paralleling them. The escort pattern had held all day.
She was thinking about Kowalski's data and what it meant and what Parr had been doing with six months of formation monitoring data when Ghost said, quietly, "He asked you specific questions."
"I noticed," Yuki said.
"Three about the data burst. Two about our transmission capability. One about where Harrison is."
She'd noticed that too. The questions had been embedded in reasonable follow-up to the things she'd shared. Technical questions that made sense in the context of a specialist who wanted to understand the plan's viability. But the pattern was specific and the specificity was interesting.
"You think he's Cole's backup," she said.
Ghost was quiet for a moment.
"I think the questions he asked are the questions someone would ask if they wanted to know how to disrupt a transmission capability," he said. "Or report its location."
"He could also be asking because he wants to make sure the plan works before he commits to it."
"Yes," Ghost said.
She let that sit. She'd made the call an hour ago, shared enough of the plan to use Kowalski as a resource. The question now was whether the call had been right.
She didn't know yet.
---
The sweep team found them forty-three minutes later.
Not Continuity security. A Meridian tactical unit, lighter gear, faster movement, designed for alien-world operation. They came from the south, from the burn zone, which meant they'd been inserted through a secondary wormhole point Yuki hadn't known existed.
Eight of them. Heavy in formation. Moving with the practiced coordination of a team that had done this before.
"Contact south," Ghost said, and was moving before the word ended.
The Wardens reacted before Ghost finished the sentence. The three at the cavity entrance moved outward into the corridor, blades deployed, forming a defensive arc.
And then the fight was happening and there was no more time for thinking about who had made what call and why.
Ghost dropped the forward Meridian element from sixty meters, two shots, the second unnecessary but fired before the first had confirmed. Santos took the left flank with a burst that drove two back into the tree cover. Yuki moved right, drawing fire off the cavity, two rounds clipping the tree trunk beside her as she went down behind root cover.
The Wardens engaged. Their combat style was nothing like Specter's. No cover, no angles, no attempts to manage the fire-exchange geometry. They moved directly into contact with the efficiency of creatures who'd evolved to fight at close range, who did not have the concept of exposure in the way that upright bilateral things with fragile organs did.
The first Meridian trooper who closed to melee range learned this quickly.
"Down, left—" Ghost called.
Santos hit the deck.
Ghost's round passed through where her head had been and dropped the trooper behind her.
Yuki was on the flank now, pushing through root undergrowth, trying to reach the angle that would let her take the Meridian commander before they reorganized. She counted six left standing. She could hear Chen in the cavity behind her, data capture running, voice rapid and technical. She could hear Doc's voice low and steady, keeping the Wardens' injured member from reacting to the combat noise.
She found the angle.
She took it.
Four left standing.
Then a Meridian trooper she hadn't tracked circled wide of the fight and came in from the cavity side, the angle Ghost wasn't covering because Ghost was managing the main line and Santos was suppressing the tree cover.
The trooper fired into the cavity mouth.
Doc threw herself across the injured Warden and took the round on her back plate. She went down hard. The round had been a restraint dart, not live. It hit her plate and detonated, spreading shock-mesh that seized her muscles and locked her flat.
The Warden at the cavity entrance saw Doc go down.
It turned from its defensive position and moved to cover her.
The gap it left in the defensive arc was two seconds wide.
A Meridian trooper came through the gap.
The remaining Warden, the one that had been motionless in the back of the cavity, the one they'd thought might be sleeping or dead, was neither. It had been still because it was wounded. It came off the floor to meet the trooper, too slow, took a full-energy shock lance hit to its primary thorax at point-blank range.
The sound it made was not a scream. It was lower than that. A sound like a building settling.
Yuki heard it from the flank.
She turned and put two rounds through the trooper before he could fire again, and the trooper went down, and the Warden went down, and she reached it in four seconds and knew from the thorax damage that Doc's skills had a limit and this was past it.
The Warden was still conscious. She could tell by the way its secondary limbs moved, not the deliberate movement of function but the slow, searching movement of something in its last minutes. It looked at her with its compound optical clusters.
She put her hand on its thorax, not knowing why.
It was still for a moment. Then it reached with one primary limb and placed it over her prosthetic arm, and held there, and she let it.
"I'm sorry," she said.
It couldn't understand the words. Maybe something in the tone.
Ghost appeared at her shoulder. He didn't say anything. He stood with her until the Warden's limb went still, and then he moved to the perimeter and swept for the last two Meridian troops who had pulled back into the tree line.
Santos came up beside Yuki.
"Where's Kowalski?" Yuki asked.
Santos's expression told her before she said it.
"Gone. During the fight, while we were on the south line." She paused. "He took the terminal. The one with his six months of data."
Yuki looked at the empty space against the root wall where Kowalski had been sitting.
She'd made the call. She'd read the signs and made the call and the Warden was dead and the data was gone and Parr now knew exactly where they were, what they'd found, and what their transmission capability looked like.
She'd been wrong.
She held that for exactly the length of time it took to become certain of it, which was very short.
Then she looked at her squad.
Doc on the ground, muscle-locked from the shock dart, already fighting toward movement. The Wardens regrouping around the cavity with the specific gravity of creatures who'd just lost one of their own. Chen still recording. Still recording, because Chen didn't stop recording.
"Kowalski filed a position report before we reached the corridor," she said. "He's been reporting since. The sweep team knew exactly where we were." She looked at the dead Warden. "We move now. Fast. We reach the formation before whatever Parr sends next arrives."
Ghost said, "Doc can't run."
"Thirty minutes," Doc said, from where she was forcing motor control back into herself, shoulder blades first, hands second. "Give me thirty minutes."
They didn't have thirty minutes.
Yuki looked at Ghost.
He said, without inflection, "Twenty."
"Twenty," she said. "Then we move."
She turned away from the dead Warden. The grief was there, not grief for the Warden specifically, though that was there too, but the grief of a mistake that had cost someone else the price. She'd been wrong and she knew she'd been wrong and the knowledge settled in her chest and stayed.
She did not name it.
She checked her rifle and counted the corridor ahead.
