The summit push started before light.
River had Dae at the front and Marcus second and the rest arranged behind by needâRenn, whose leg was holding but only just; Lia, close to Marcus; Cal and herself at the midpoint where they could move forward or back as needed; Fenno, Kai, Darro at the rear. Nine people was a different organism than six. She'd been running six for long enough that the expansion required actual recalibration, new spacing, new watch logic, new fuel math.
She recalibrated.
The mountain didn't care how many people you brought to it.
---
The snowline arrived at the second hour.
Not a line exactlyâa gradient, the snow appearing in patches first, the rock face whitened in the shadowed sections, then the patches becoming the ground itself. Dae altered pace when the snow started. Slower but more deliberate, her feet finding the solid places in the crust rather than letting the crust take her weight on faith.
River did the same.
She'd grown up with winter. Not mountain winterâher village had been in the eastern valley where winters were hard and wet rather than cold and technical. This was something different. The cold here was clean and specific, each breath a calculation: enough to fuel the next step, not so much that the lungs protested.
Fenno fell into step beside her for the mid-morning section.
She'd been wondering when he would.
He was younger than Dae and Kaiâtwenty at most, with the angular face of someone who'd grown up mostly outdoors and the particular economy of movement that came from years of running routes. He hadn't spoken much since the camp merge.
"You're the one with the original documentation," he said.
Not a question.
"Yes," she said.
He held that.
"I joined the circuit eight months ago," he said. "Dae recruited me at the eastern approachâI was running supply routes for a settlement and she needed someone who knew the lower foothills." He paused. "I didn't know what I was carrying, specifically. I knew it mattered. I knew why it mattered in general terms." He looked at her. "I know more now."
She held her gaze forward.
"And," she said.
He looked at the mountain.
"I want to know we're going to get it there," he said. "The Sanctuary. The originals." He held her gaze. "Not as a mission. As a fact. I want to know we're going to actually do it."
She looked at him.
She thought about what she could honestly say.
"We're going to do it," she said. "That's what I know."
He held her gaze.
"Okay," he said.
He fell back to his position.

Marcus ceded point to Dae at the snowline proper.
It happened without dramaâhe'd been walking second position behind Dae all morning, and at the point where the snow became continuous coverage, he stopped and stepped aside and let Dae move to the front and he took the position behind her. Clean.
River had been watching for it.
She came up beside him when he fell back.
"Summit navigation," she said. "You know the lower section."
"Dae knows the full route," he said. "I know pieces of it. The healer circuit changed the western approach in Year 11âthe path I walked in Year 9 is different from the current route in the upper sections." He looked at Dae's back. "She has more recent knowledge than I do."
She held his gaze.
"That's not the whole reason," she said.
He was quiet.
"The snow section is harder," he said, finally. "The pace required for technical snow work is notâ" He stopped. He breathed. "I can walk this. I can't walk it at the speed Dae sets. If I'm at point I slow the group."
She held that.
She kept walking.
"Then you're not at point," she said.
"No," he said.
She breathed.
She let Dae set the pace and she stayed at the midpoint position and she watched Marcus's feet in the snowâdeliberate, careful, each step placed with the extra attention of someone who couldn't afford a fall.
He wasn't slow.
He was just careful in a way he hadn't been before.
---
They stopped at the day's high point for twenty minutes.
Rock formation giving cover from the western wind, which had started in the late morning and was building. River had been tracking the clouds Marcus had said were two days out. They were still two days out, but the wind was their advance notice.
She ate.
She made herself eat the full rationâshe'd been running light for days and she knew it. The mountain was going to ask things of her body over the next two days and the body needed the fuel.
Cal sat beside her.
He'd been running the rear position with Darro for most of the dayâthe two of them had developed a quiet back-position coordination that required no discussion. She appreciated that about both of them.
"Lia's keeping an eye on Marcus," he said.
"I know," she said.
"He's managing," Cal said.
"I know," she said.
She ate.
She looked up the slopeâthe route Dae had been reading, the switchbacks that zigzagged through the upper snow field. From here she could see the summit plateau's edge, maybe three hundred meters of altitude above. A day's work. Hard work.
"Tell me what you're actually thinking," Cal said.
She looked at him.
He looked back.
She breathed.
"That the cache was the buffer," she said. "I had a plan that had a buffer. Now there's no buffer." She looked at the route. "We get through the summit in two days and we reach the western shelter in one more and we find what's there or we don't and we hold the math together with both hands." She held his gaze. "And Marcus is going to make it because that's what's going to happen."
Cal held her gaze.
"Okay," he said.
"I'm not asking you to believe it," she said. "I'm telling you what I've decided."
He looked at the route.
"It might just be the same thing," he said.
She held that.
She didn't answer.
They ate.

The upper snowfield was where the mountain started being honest.
The snow was different hereânot the patchy crust of the lower section but a consistent surface, wind-consolidated, with the specific hardness that cracked under weight rather than compressing. Dae moved across it in a pattern River worked to decodeânot random, not just cautious, but reading the surface for the places where the consolidation held and the places where it might not.
River read the same surface and made most of the same choices.
Most.
The difference was the specific knowledge. Dae knew which slopes had what kind of compaction at what angle. She knew where the wind had deposited snow versus where it had scoured it. She moved through the knowledge the way Marcus moved through the lower forestânot thinking, just knowing.
River filed everything.
She was always filing everything.
At the hour mark, Kai came up beside her.
"Dae mentioned you come from the eastern valley," Kai said.
"Yes," River said.
"Village background," Kai said.
"Yes," River said.
Kai was quiet for a moment.
"I was from the southern settlements," she said. "The coastal ones, before they flooded." She looked at the mountain. "I've been on the road for six years. I don't actually know what I'd do with a settlement anymore." She paused. "Does the Sanctuary feel real to you. From what you know."
River thought about the twelve pages. About her mother's handwriting and the specific pragmatism of itâ*a place can outlast groups*.
"Yes," she said.
"Not as a wish," Kai said. "As a place."
"My mother built it," River said. "My mother died for it. It's real." She held Kai's gaze. "It's real the way the documentation is real. Because people chose to make it real and paid the cost."
Kai looked at the summit.
"Okay," she said.
She fell back.
---
They made the high camp in the late afternoon.
A natural shelf in the rock face below the summit plateau, wide enough for nine people to sleep flat, sheltered on three sides. Dae knew itâshe moved to it without explaining, and Marcus nodded when he saw it, and that double confirmation was enough for River.
She looked at the plateau edge above them.
In the morning.
The wind had dropped at the high camp, the shelf cutting it. Stars were coming out over the western side of the rangeâmore stars, River thought, than she'd ever seen in one sky. No light pollution. No atmosphere pressure from low elevation.
Just the mountain and the stars and nine people trying to get to the other side.
She sat with the satchel in her lap and went through the originals one more time. Not readingâchecking. The materials were dry, undamaged. The folder that held her mother's pages was intact.
She closed the satchel.
Marcus sat beside her.
He didn't speak for a while.
"She would have made this crossing," he said, finally.
She looked at him.
"Your mother," he said. "She knew the route. She'd planned the Sanctuary's location specifically because of the mountainâthe crossing was the protection. Anyone who wanted to reach it had to make this climb." He held her gaze. "She planned that deliberately. She wanted the Sanctuary to be hard to reach."
River held that.
"You know more than you've said," she said.
He held her gaze.
He didn't answer for a moment.
"Yes," he said. "There's something I should tell you." He paused. "Not tonight. Tonight you need to sleep for the summit. Tomorrow, on the plateau." He held her gaze. "In the morning."
She looked at him.
"It's not bad news," he said. "It'sâit's the kind of news that changes something. The kind you need daylight for."
She held his gaze.
She wanted to ask now.
She didn't.
"Tomorrow," she said.
"Tomorrow," he said.
He stood.
He went to his bedroll.
She sat for a moment longer, looking at the stars above the western peaks, holding the specific shape of what she was heading towardâthe Sanctuary, the names, the evidence her mother had died to preserve.
The wind picked up again, briefly, and then dropped.
She lay down.
She slept without fighting it.
