"The three-point approach." Fenn tapped the map with a knuckle — the hard rap of a man who hit things to make them pay attention. "You wrote that they attack from three simultaneous vectors. Which three?"
"The weakest wall section. The primary gate. And an elevated position for suppressive fire." River's voice was raw. Two hours of talking hadn't helped. "Marcus said the third point isn't about breach — it's about keeping defenders pinned so they can't reinforce the other two."
"The elevated position." Fenn traced the ridgeline on Thorne's map. "East ridge or west?"
"Whichever has the best sight lines into the compound. They want crossbow fire over the walls, not into them."
"West ridge." Fenn's knuckle moved. "The east is too steep for a sustained position. The west has that shelf — here, three hundred meters up — with a direct line to the courtyard and the south gate."
River looked at the map. Thorne's handwriting marked the shelf: *Western overlook. 15m x 8m flat. Natural parapet. Elevation 312m.* Geography turned into information.
"If they hold that shelf, they can hit anything inside the compound that isn't under a roof." Fenn's jaw tightened. She could see it happening — the old soldier laying the theoretical doctrine onto actual terrain, watching theory become an operational plan. "Webb wrote this for open-ground settlements. How does it adapt to a valley compound?"
"He didn't tell me the adaptations. He said the doctrine was a framework and Cain would modify it for terrain."
"Then we modify it for him." Fenn picked up River's pages. Flipped to the weaknesses section. Read it again — the third time. "Communication between teams. You said disrupting communication disrupts synchronization."
"The three-point approach requires coordinated timing. If the teams can't signal each other, they can't synchronize. One team hits early, defenders concentrate there, the other two arrive at a prepared defense instead of a divided one."
Fenn grunted — the noise a craftsman makes when a joint fits. He wrote something in the margin of Thorne's map. Small, precise, military handwriting. River couldn't read it upside down.
"Go eat," Fenn said. "Come back at noon. I need to think."
River went.

The compound had changed while she'd been in Fenn's office.
Not the buildings or the walls — those were the same. The change was in the motion. The Sanctuary's rhythm had shifted from the steady pace of a working community to something faster, more uneven. A place that knew danger was coming and was trying to get ready without knowing when.
Sable's harvest crews were in the fields. All of them. Not the organized teams of yesterday — today it was everyone. River stood at the south wall and watched. Men, women, teenagers bent over the rows, pulling vegetables with the urgency of people who understood that food in the ground was safer in the cellar. Sable moved between them, pointing, redirecting, her voice carrying in short commands. *Pull the roots. Leave the greens. Stack by the wall.* She'd become something else overnight — not a farmer but a quartermaster, converting growing things into stored things before they became ashes.
At the south wall, Garrett's crews were building. Hammering that never stopped — a rhythm under everything else. River watched four men lift a timber beam into position at the wall top. A firing step, she realized. A platform for crossbow shooters to stand above the wall line and fire down. The engineering was rough. Joints pinned, not mortised. Good enough. Fast enough.
"It'll hold," Petra said.
River turned. The woodworker had materialized beside her — no approach, no announcement, just suddenly there. She was eyeing the firing step.
"The joinery's ugly," Petra said. "But the load path is sound. Whoever designed these knows his timber."
"Garrett."
"I've been working with him since dawn. He thinks in structures." Petra flexed her hands. The knuckles were raw. "He's got a problem at the south gate though. The bar mechanism — the counterweight — it's been maintained for normal use, but nobody tested it against a battering ram. Six men with a log. The mechanism would hold maybe two impacts before the pivot fails."
"Can you fix it?"
"Already did. Replaced the pivot with a through-bolt and added a secondary bar that drops into floor sockets." Petra looked at her. "You look like you haven't slept."
"I haven't."
"That's stupid. You should sleep."
"I should do a lot of things." River turned from the wall. "Are Cal and Thorne —"
"Cal's in the cellar counting food. Thorne's with the soldier. The old one."
"Fenn."
"They've been in the map room since before I was up. Your waypoint keeper is a strange man, River. But he draws a good contour line."
Petra left without a goodbye. She was there and then she wasn't, and the space she'd occupied filled with the sound of hammering.

River found Cal in the cellar beneath the main building. Cool, dry, organized with the precision of people who knew that organization was the difference between eating in March and starving in March. Shelves lined the walls — jars, bags, crates, bundles.
Cal stood in the middle with a notebook and a pencil stub and the look of a man doing math he didn't like.
"Three hundred and twelve people as of this morning," Cal said without looking up. "Sixty-three refugees from the eastern settlements showed up at dawn. Families. Children. Population's up twenty percent in twenty-four hours."
"How long can we feed them?"
"Current stores, strict rationing —" He ran the pencil down a column of figures. "— two months. Sable's emergency harvest adds another three weeks. Call it eleven weeks total before we start deciding who eats and who doesn't."
"And the water?"
Cal looked up. The warmth was set to low — not gone, but dimmed. The trader was working, seeing systems and flows and bottlenecks, and he'd found a bottleneck nobody else had caught.
"The stream." He pointed upward, toward the valley where the stream fed the irrigation system and the reservoir. "It enters from the northwest. Through a gap in the western ridge. Snowmelt from above. Runs about a mile through open ground before it reaches us."
"Open ground."
"Open, undefended ground. If the Riders dam it or divert it — which is not hard, ten men with shovels could do it in a day — we lose our primary water source." Cal tapped the notebook. "There's a well. I checked the flow rate this morning. Bucket and pump. Maybe fifty gallons an hour at peak."
"Enough?"
"For three hundred people in normal conditions, barely. For three hundred and sixty under siege — higher stress, higher activity, medical needs, cooking — no. We'd be rationing water within a week."
River stared at the jars on the shelves. Eleven weeks of food. Cal's math, Fenn's math, everyone's math — how long, how many, how much, and whether the numbers added up to living.
"Tell Fenn," River said. "About the stream."
"I'm telling you first." Cal met her eyes. "Because Fenn's going to want to fortify the stream approach and I want you to understand why that's a mistake. We can't fortify everything. We don't have the people. Every position we defend is a position we have to staff, and every person on a wall is a person not in the fields or the lab or the cellar. The stream is vulnerable. We have to accept that and plan around the well."
"Plan for rationing."
"Plan for rationing." Cal closed the notebook. "It's what I'm good at. Let me do it."
River left. Behind her, Cal reopened the notebook and the pencil scratched on paper.

Dara had set up a training ground behind the main building. A cleared space, maybe forty feet square, with straw bale targets at one end — crude charcoal silhouettes drawn on canvas.
Thirty people stood in a loose line. Farmers. Builders. Kitchen staff. A woman River recognized from the mess hall. A man she'd seen hauling timber for Garrett. Hana, the cook, holding a crossbow the way she might hold someone else's baby.
Dara walked the line. Crossbow slung. Voice carrying without shouting.
"The crossbow is a simple mechanism. You load the bolt. You aim. You pull the trigger. The bolt goes where the crossbow was pointed when you pulled." She stopped in front of a man whose crossbow was angled at the ground. "Which means if you point it at your foot, you're going to have a very bad day."
He adjusted his aim. His hands were shaking.
"You don't need to be a marksman," Dara continued. "At the distances we'll be fighting — twenty to forty feet from the wall top — you point in the general direction of a person and pull the trigger. The bolt handles the rest."
"What if we miss?" From a woman near the end of the line. Young. Hands steady, voice not.
"You reload and try again." Dara reached the end of the line. Turned. "The Riders are trained fighters. You're not. I won't pretend two days of practice makes you their equal. What it does is put bolts in the air. A lot of bolts. Fired from an elevated position behind a wall, that slows down even a trained force. You don't have to be good. You have to be present."
River watched from the doorway. The volunteers fired. Clicks and thuds — mechanisms releasing, bolts hitting or missing targets. Most went wide. Some hit the bales. A few found the silhouettes. One sailed over everything and stuck vibrating in the back wall of a storage shed.
Dara didn't react to the misses. She walked the line, corrected grips, adjusted stances. Put her hands over someone's hands and guided the aim the way you guide a child's first steps — not doing it for them, just keeping them upright.
Hana fired. The bolt punched into the center of the left target. Dead center. Buried to the feathers.
Dara looked at the target. Looked at Hana. "You've shot before."
"My husband was a hunter." Hana loaded another bolt — quick, practiced hands. "Before." The word carried what it always carried — the Before, when things were different. She fired again. Two inches from the first bolt.
"I want you on the south wall," Dara said. "Firing position three."
Hana nodded. Reloaded. The cook who could put a bolt through a target at forty feet because her dead husband had been a hunter.
River turned from the doorway.

The refugees arrived in groups throughout the morning. Staggered, the way people flee when the warning comes — grab what you can, walk away from the thing you're running from.
Two families from the nearest eastern settlement. Then four more from the second. They came through the east gate with bundles and children and the wide-eyed look of people told to leave home. Some children were crying. Others were silent — the silence of kids who'd learned that noise was dangerous.
River watched them come through. A woman carrying a baby. A man carrying a box that might have been everything he owned. Two brothers holding hands, the older one maybe eight, the younger maybe five, the older one wearing a seriousness that didn't belong on an eight-year-old's face.
Mira was at the gate. Someone — Hana, maybe, or one of the other residents — had given her the job of guiding refugees to the mess hall for food and the quarters for space. She moved between the new arrivals with a quiet competence that came from having walked through her own worst night and found something to do on the other side. She spoke to the children. Low. Gentle.
The compound was growing. Three hundred had become three sixty and was still climbing. More mouths. More fear. Cal's numbers in the cellar getting worse with every family that walked through the gate.

Vance found River in the courtyard at midafternoon.
"I need you." Clipped. Not unfriendly — efficient. A woman who needed something specific.
River followed her to the lab. Sat on the table. Offered her arm. The routine was becoming familiar — cotton ball, rubber tubing above the elbow, needle, vial filling with dark red blood. Her body's contribution. The transaction that justified her presence behind these walls.
Vance drew two vials. Labeled them. Set them in a rack beside three others from the morning draw. Then she turned to the workbench and picked up something small.
A vial. Smaller than the blood vials. Clear liquid inside, faintly yellow — the look of something refined and filtered and separated from its source.
"Antibody concentrate," Vance said. She held it between thumb and forefinger at eye level, tilted it into the light. "Extracted from your plasma. Ammonium sulfate fractionation. Crude by pre-Collapse standards. Effective by current ones."
"What does it do?"
"In theory, it neutralizes the primary plague variant. The antibodies, administered to an infected patient, should bind to the pathogen and let the patient's immune system clear the infection." She set the vial down. Precisely. On a specific spot. "In theory."
"You haven't tested it."
"We have no infected patients. The isolation that's protected us from Riders has also protected us from plague exposure. Testing would require —" She stopped. Started over. "It would require a controlled exposure trial, which raises ethical questions I'm not prepared to — that would need extensive protocol review."
"It works or it doesn't."
"It should work." Vance's voice shifted — same vocabulary, but something underneath moved. Lower. More personal. A woman who'd spent eleven years working toward this moment, standing in front of it, not quite letting herself believe it. "The biochemistry supports it. The antibody titers are sufficient. The binding affinity to the viral spike protein is — remarkable. Your blood produces antibodies more effective against this pathogen than anything in the literature."
She picked up the vial again. Clear liquid in afternoon light.
"If we had time — months, not days — this could become a treatment. Mass-produced. Distributed. The plague variants still killing people in the southern territories, the eastern corridors, settlements without medical infrastructure — this could reach them."
"Could."
"Could." She set it down. The scientist snapped back into place. "But we don't have months. We have days. Maybe less." She turned to River. "I need you healthy. Blood volume maintained. Nutrition adequate. Stress levels — well. They are what they are. But everything else I can control, I will." A pause. "Your sutures look good. Wound's closing clean. I'll remove them in three days."
"If we have three days."
Vance didn't answer. She labeled the vial, filed it, went back to the centrifuge and the microscope and the work that might save people if there were enough people left to save.
River left the lab. Afternoon sun was low. The compound was loud with construction and training and three hundred and sixty people trying to become something that could take a hit.
She headed for Fenn's office. He'd said noon. It was past noon. She was late and didn't care — being late was a luxury you could afford inside walls.
She was halfway across the courtyard when the whistle came.
Not from the east gate. Not from the south. From above — from the western ridge, from the observation post Fenn had put on the high ground overlooking the gorge.
Three notes. Fast. Pause. Three more.
Dara's head snapped up from the training ground. Fenn appeared at his window. Garrett's hammering stopped.
"Contact signal," Dara said. She was already moving toward the west ridge trail. "Someone's at the gorge."
River followed. She shouldn't have — she wasn't a scout, wasn't armed. She followed because the gorge was the direction Marcus had gone and every signal from that direction might be about him.
The trail to the observation post was steep. Switchbacks through forest. Five minutes of climbing. River's sutures pulled. Her legs burned. Behind her, Dara and two scouts moved with the ease of people who'd climbed this trail a hundred times.
The post was a rock shelf — natural, high, exposed. Two guards crouched behind the lip, looking south through a gap in the trees toward the gorge.
River reached the shelf. Looked.
The gorge below — rock, white thread of river, empty air where the bridge had been. The far side visible: tree line, trail, terrain that belonged to the Riders now.
A figure stood at the far edge.
One man. In the open. Not hiding. Standing where he'd be most visible, the posture of someone who wanted to be seen.
He held something above his head. White. A shirt or strip of fabric. The white flag. The signal that predated the Collapse and would outlast whatever came after: *I want to talk.*
His voice carried across sixty feet of air. The gorge acoustics amplified it, bounced it between rock walls, delivered it with surprising clarity.
"Message for the compound. From General Cain, Commander of the Crimson Riders, Third and Fifth Mounted Companies."
Dara reached the shelf. Dropped beside River. Crossbow up — aimed at the figure. Sixty feet. An easy shot. The man on the far side knew that. He was standing there anyway.
"General Cain requests a meeting," the man shouted. "Face to face. At the gorge edge. Tomorrow at noon. He will come with one escort. He requests the compound send a representative with one escort." Rehearsed — the syntax careful, the phrasing deliberate. "General Cain says he has a proposal. He says the proposal benefits both parties. He says he comes in good faith."
The last words echoed off the walls. *Good faith. Good faith.* The rock repeating it, indifferent to the meaning.
"He also says —" The man paused. The rehearsed delivery faltered. He was reaching the harder part. "He says he has something that belongs to you. A man. A former officer. Alive."
*Alive* bounced through the gorge and landed on the shelf where River crouched with her hands on the rock and her knuckles white.
Marcus. Alive.
Cain had Marcus and wanted to talk and was coming to the gorge tomorrow at noon with a proposal that probably meant River's blood and probably cost everything else.
Dara looked at River. Professional mask in place. But her eyes were asking something her mouth wouldn't form.
The messenger waited on the far rim.
"Tell him we'll be there," River said.
