Chapter 57: Northgate

The Northgate scout's name was Solis Abad, and she was forty-four, and she had the kind of face that gave nothing away involuntarily.

River had a category for faces like that—she'd met people who'd been through enough that the default expression became neutral, not because they were hiding things but because they'd learned that showing things was a cost they couldn't always afford. Solis sat in the east outbuilding entry with her hands visible and her posture open and she watched River come in with the steady attention of someone sizing up a negotiating partner.

River sat across from her.

"You came alone," River said.

"I'm a scout," Solis said. "That's what scouts do." Her voice was level, a slight accent River couldn't place exactly—southwest, somewhere. "I came through the northwest approach. The Rider perimeter has a gap there—they don't have anyone watching that corridor."

"Why not," River said.

"The terrain is difficult and they don't know it," Solis said. "We know it." She held River's gaze. "Northgate has been in this territory for six years. We know every approach. The northwest corridor is how we operate when the southern passes are contested." She paused. "The same corridor is how we'd bring fighters and supplies to you, if that's something you want to discuss."

"Tell me about Northgate," River said.

Solis told her. The settlement was fourteen kilometers northwest—built into a series of old warehouse structures that had been converted over the years into something livable, defensible, self-sufficient. Population three hundred and twenty, of which sixty were fighters. They had food stores, ammunition, medical supplies.

River listened and did the math. Sixty fighters plus forty-nine rifles—the south wall would hold much better with a hundred and nine. The ammunition concern, which had been keeping her up, would ease. The three dead on the south wall this afternoon—they'd been three positions. Three positions needed filling and she didn't have them.

"What do you want," River said.

"We want access to the cure research," Solis said. "Not exclusive access. Share the synthesis documentation, share the baseline data. Northgate has medical capacity and the people to distribute." She paused. "When the synthesis is complete, Northgate gets the same access as this Station."

River heard the terms and found them entirely reasonable. She was going to share the synthesis documentation with every settlement she could reach—that was the point. That was what her parents had built the Station to do.

"The fighters and supplies," River said. "Timeline."

"If you agree tonight, I leave at dawn through the northwest corridor," Solis said. "I'm at Northgate by noon. We can move a combat team and supply load back through the corridor in—" She calculated, visibly. "Thirty-six hours. End of tomorrow, early the day after."

River thought about thirty-six hours. Thirty-six hours of current conditions—Cain probing, the east wall holding, the ammunition concern stretching.

"One more condition," she said. "The fighters. They operate under my command while they're here. Not yours, not Northgate's. Mine."

Something moved in Solis's face. Not quite resistance—evaluation. "Agreed," she said. "With the understanding that my people have their own command structure that I need to communicate through."

"Communicate however you need to," River said. "But when there's a tactical decision in this station, it's mine."

"Agreed," Solis said.

The agreement was simple. River made it, shook the offered hand, and sent Solis to get food and a place to sleep before her dawn departure.

She walked back to the main building.

Something sat slightly wrong in her chest. Not wrong enough to name—just the specific off-texture of a negotiation that had gone too smoothly.

She told herself she was tired and looking for problems that weren't there.

---

Cal had found something.

He was at the main table with his map board when she came in, and he had a survey laid out—the northwest approach, the corridor Solis had come through. He'd been adding annotations since—she looked at the time, it was past seven—since before Solis had arrived, which meant he'd been tracking the Rider positioning all afternoon and had noticed something without knowing yet what it meant.

"The northwest corridor," he said.

She sat across from him. "Solis came through it."

"I know." He pointed at the survey. "The Rider perimeter—they have the south approach fully covered. East is the cliff approach they probed. North and northeast are the natural cliff, which they're not watching." He traced the northwest. "This corridor should be watched. Any force commander worth his position would cover this approach to prevent exactly what Solis did—an ally reaching us." He looked up at her. "They're not covering it."

"Solis said the terrain is difficult."

"Difficult is not impossible," he said. "And Cain is not a man who leaves gaps because terrain is difficult. He leaves gaps when he intends them." He held her gaze. "This corridor—left open deliberately—functions as a route that looks like a weak point in their perimeter but isn't."

River sat with that.

"It's a funnel," she said.

"It could be," he said. "A force coming through the northwest corridor would be confident they'd evaded the Rider perimeter. They'd reach the Station thinking they'd slipped through. But if there were secondary positions—" He indicated points on the survey. "Here and here. Outside the primary perimeter line. Concealed. A force coming through the corridor would be walking between them."

River looked at the survey.

Sixty Northgate fighters coming through a gap the Riders had deliberately left open. Confident they'd evaded the perimeter. Walking between secondary positions they couldn't see.

"That's if Cain anticipated Northgate would try to help us," she said.

"Or if Cain anticipated *someone* would try to help us," Cal said. "The gap has been there since the advance element arrived. It was there before Solis showed up."

River held the map.

"Or Cain knows about Northgate already," she said. "Knows they'd make contact. Knows the corridor route." She paused. "And left the gap for exactly them."

Cal's expression stayed level. "Yes."

She thought about Solis's face. The face that gave nothing away involuntarily. The negotiation that had gone too smoothly. The conditions that were entirely reasonable.

"She might not know," River said. "Solis. If Cain made a deal with Northgate's leadership and she was sent as the honest face of it—she might genuinely believe she's offering an alliance."

"Yes," Cal said. "Or she knows."

River looked at the survey. At the northwest corridor. At the gap in the Rider perimeter that should have had people in it and didn't.

"I need to talk to Marcus," she said.

---

Marcus was in the facility common area, which meant the area adjacent to the lab where Ines and Vance weren't currently working. He'd been going through his camp records packet in the facility's good lighting, laying out the documents he'd taken in a sequence that suggested he'd been organizing them most of the day.

He looked up when River came in. Then at her face. Then back at the documents.

"Something happened," he said.

"Northgate scout. Settlement to the northwest. Offering fighters and supplies." She sat across from him. "Cal thinks the Rider perimeter gap to the northwest is deliberate."

Marcus was quiet for a moment. Then: "Northgate." He said the word the way you said the name of something you recognized. "You sure that's what she said."

"Northgate. Fourteen kilometers northwest. Three hundred twenty people."

"Six years old," Marcus said.

"She said six years," River said. "Yes."

He was quiet again, in the way that meant he was thinking rather than stalling. River had learned the difference.

"Who runs it," he said.

"She didn't say. She said she was a scout—Solis Abad."

Marcus nodded slowly. "I know the name Northgate," he said. "I've heard it on the trade routes going back three years. Well-regarded settlement. Does honest trade." He paused. "But." He looked at the documents on the table. "Three years ago, Northgate's supply route went through Rider territory. Not through—adjacent to, technically, but they needed Rider tolerance to move their goods." He looked at River. "I don't know what the terms of that tolerance were. I don't know if they've changed." He paused. "I didn't know Northgate and the Riders were relevant to each other until you just told me where Northgate is and where the gap in the perimeter is."

River looked at the documents. "What do your camp records say."

"I've been going through them for two days," Marcus said. "I haven't found Northgate specifically." He pushed a set of pages toward her. "But I found a reference to a northwest corridor scout operation—dated two weeks ago, before we arrived at the Station. Someone had been assessing the northwest approaches." He tapped the page. "The assessment notes: *corridor usable by allied units, recommend holding open for future use.*"

*Allied units.*

Northgate was an allied unit. Not coerced—allied. Actively working with the Riders.

And Solis had come through the corridor tonight and offered sixty fighters and supplies and very reasonable conditions.

River breathed.

"I'm going to go think," she said.

Marcus nodded. "You should know," he said, "that the alliance doesn't necessarily mean Solis knows about it. Leadership makes deals. Scouts follow orders." He held her gaze. "She may genuinely believe she's helping you."

"Or she genuinely believes she's helping you while planning to deliver you," River said.

"Yes," Marcus said. "Or that."

She went back to the main building.

---

She didn't sleep that night.

She lay down in her section of floor and held the information in the careful way she held things that needed to be held before being decided on. The Northgate alliance—possible, not confirmed. The camp records reference—suggestive, not definitive. The gap in the Rider perimeter—deliberate, probably, but possibly just a gap.

She'd agreed to the alliance. Solis was sleeping in the east outbuilding. At dawn she'd leave through the northwest corridor and return in thirty-six hours with sixty fighters and supplies.

River could let her go and prepare for the fighters to arrive as either an alliance or a Trojan horse and deal with it at arrival. She could have Cal follow Solis through the corridor—track her, see where she actually went. She could call Solis back in tonight and push harder on the conditions and see where the pressure went.

None of those were clean options.

She thought about the timing. Cain knew the baseline was complete. He'd probe again tomorrow—the north approach, possibly, or another south assault, or another east wall attempt. She needed the sixty fighters. She needed them to be real. If Northgate was genuine, she needed that alliance. If Northgate was Cain's, she needed to know before sixty fighters were inside her walls.

By three in the morning she had a plan. Not a complete one—the kind with specific gaps she'd have to fill in real time. But a plan.

She found Cal at the east watch.

"The corridor approach," she said. "Can we set watchers along it—not to intercept Solis, but to observe what's at the end of it."

Cal looked at the night sky—the direction of the corridor, the terrain. "Two people. Well before dawn. They'd need to be in position before Solis leaves and stay ahead of her the whole corridor." He paused. "It would require going outside the wall."

"Through the north approach," River said. "The cliff descent. The one the assault team used."

"Yes." He looked at her. "I'd go."

"No," she said. "Not you." She thought. "Dara."

"Dara and someone else," he said. "Alone is—"

"Dara and Eli," River said. "Eli knows this terrain better than anyone. He spent eleven years watching these approaches."

Cal was quiet, thinking it through.

"They leave at four," he said. "Through the north cliff descent. Ahead of Solis by two hours. Reach the corridor mouth, set a position, observe where she goes." He paused. "What do I tell them to look for."

"Secondary positions in the corridor," River said. "Concealed. Riders waiting. If the corridor is clean—no secondary positions—then the gap is genuinely a gap and Northgate might be genuine." She held his gaze. "If they find what you think is there—they come back and tell us."

"Before Solis gets to Northgate and returns with sixty fighters," he said.

"Before that," she said. "Yes."

He went to wake Dara and find Eli.

River went back to the south wall.

The night was cold and clear. The Rider camp fires at the tree line were low—the camp was at rest, the same rhythms she'd been watching for three days now. The morning would bring whatever it brought.

She stood at the wall and looked south and thought about sixty fighters coming through a corridor that was either a gap or a trap. She thought about Solis's face—the neutral face, the face that gave nothing away.

*She might genuinely believe she's helping you.*

Or not.

River stood at the wall until dawn and then helped brief the morning watch and ate something when Sable put it in front of her.

At four-thirty, Dara and Eli went over the north cliff.

At six, Solis left through the northwest corridor in the gray morning light.

At six-fifteen, Marcus came to find River at the south wall.

"The camp records," he said. "I found Northgate."

She looked at him.

He held out a page. Settlement alliance records—coded, dated six weeks ago. River read the summary. Northgate leadership had agreed to provide intelligence on the mountain Station and to facilitate Rider access through the northwest corridor in exchange for full trade route protection and a supply guarantee.

Six weeks ago. Before River's column had arrived at the Station.

Before Solis had ever come through the corridor.

Northgate had been working for Cain before River had ever been a factor. The sixty fighters weren't an alliance they were offering. They were the delivery mechanism.

River folded the page and put it in her vest pocket.

"Dara and Eli are in the corridor," she said.

"Yes," Marcus said.

"When they come back, we'll know what we're working with."

He looked at her with the look she'd been getting from him since the compound fell—the look of someone who'd walked with her long enough to know when she'd already done the calculation and was waiting on the last variable.

"You already know," he said.

"I already think I know," she said. "I need to confirm."

He cleared his throat. "What's the plan."

She looked at the south wall. At the force below. At the morning light hitting the slope.

"We let the sixty fighters come," she said. "But we're ready for them when they arrive."

Marcus looked at her for a long moment.

"That's a significant risk," he said.

"Yes," she said. "But it's also the only way to get sixty people inside the Rider perimeter without the Riders knowing." She turned to look at him. "If they're Cain's people—they're walking into our walls. We control the inside." She paused. "If they're genuine—we have sixty fighters."

"You said *when they arrive,*" Marcus said. "Not *if.* You've already decided to let them come."

She looked back at the south wall.

"Get some rest," she said. "You're going to need it."

He made a sound—not agreement, not refusal. The sound he made when he'd decided the conversation was where it needed to be and further pressure wouldn't change anything.

He went back inside.

River stood at the wall and watched the morning and waited for Dara to come back and tell her what was in the corridor.
