Three days of peace. That was all Ashenmere got.
Ethan was elbow-deep in mortar, patching the western wall section that had cracked during the ash storm, when Nyxara materialized from a shadow behind him. No warning. No footsteps. Just suddenly there, like she'd been part of the wall and decided to stop pretending.
"We have a problem."
"Good morning to you too."
"It is not a good morning." Her violet eyes were flat. Battle-mode flat. "My scouts just returned from the southern approach. Baron Graves has hired the Crimson Fang."
Ethan set down the trowel. Mortar dripped from his fingers onto the stone. "The what?"
"Mercenary company. Professional killers. Not border thugs with rusty swords -- trained soldiers who fight for coin and kill for fun." She paused. The wind caught her hair and she didn't bother pushing it back. That's how Ethan knew it was serious. Nyxara only ignored her hair when she was calculating kill orders. "Two hundred of them. With cavalry. And a siege wagon."
The mortar on his hands dried in the wind. He didn't notice.
"Two hundred."
"Two hundred."
"We beat thirty and he sends two hundred."
"He is spending real money to erase us. Whatever we are sitting on -- his smuggling route, his territory, his pride -- it is worth more to him than the cost of an army."
Ethan wiped his hands on his shirt and walked toward the command shelter. Nyxara followed. She didn't have to ask where he was going.

He unrolled the blueprints on the table. Rowan was already there, eating something that might have been bread. Lena sat in the corner, reviewing her medical supplies with the expression of someone counting bullets before a siege.
Greta leaned against the doorframe. She hadn't been invited. She showed up anyway. Her bandaged hand rested at her side, Lena's neat stitching hidden beneath clean linen.
"Two hundred soldiers," Ethan said. "Cavalry. Siege equipment. Professional mercenaries."
Rowan stopped chewing. "Come again?"
"Baron Graves hired the Crimson Fang."
"The Crimson--" Rowan put down the bread. "Boss. The Crimson Fang wiped out a fortified town of six hundred last spring. With half those numbers."
"Good. That means they're confident. Confident people get sloppy."
Rowan stared at him. Then at Nyxara. Then back at Ethan. "I know that face. That's his 'I'm about to do something insane' face."
"I don't have a face."
"You absolutely have a face. It's the face you made right before you collapsed a wall on thirty soldiers."
Ethan ignored him and turned to Greta. "You know the terrain south and west better than anyone. I need eyes on their column. Speed, formation, supply lines. Can you scout without being seen?"
Greta straightened. Her ears went forward. "I'm a Fenrir. I was tracking prey before I could walk."
"I'll take that as a yes."
"I'm not one of your people," she said. But she was already moving toward the door. "I owe you a debt. Fenrir always pay."
She was gone before anyone could respond. Her tail brushed the doorframe on the way out.
Rowan watched her leave. "She's terrifying and I love her."
"You love everyone who scares you."
"That's because scary women are the only honest ones."
"Focus, Rowan."

Lena spoke up from her corner. Her voice was calm, but her hands had stopped sorting bandages.
"Ethan. We have fifty-two people. Twenty can hold a spear. Most of them learned which end is the pointy one last week." She looked at him. "They have two hundred trained soldiers."
"I know."
"We have wounded from the last fight. Limited medicine. Twelve children, six elderly, and three pregnant women who cannot fight and should not be anywhere near a battlefield."
"I know, Lena."
"So what's the plan? Because 'collapse a wall on them' doesn't scale to two hundred."
He pulled out a second sheet. A topographic sketch of the valley -- every ridge, every water channel, every elevation change within two kilometers of Ashenmere.
"We don't fight two hundred. We fight twenty at a time."
Nyxara leaned forward. Her silver hair caught the firelight. "Explain."
"Three defensive rings." He drew circles on the map with charcoal. "Outer ring: funnels. Everything that looks like a path leads to where I want them. The approaches that look clear are the ones with traps. The ones that look dangerous are actually safe -- for us."
He drew the second ring. "Middle ring: delays. Mud zones, pit lines, barricades that force them to bunch up and slow down. Heavy cavalry can't charge through three feet of saturated soil. Infantry can't hold formation in a maze."
Third ring. "Inner ring: the kill zone. By the time they reach our walls, they're exhausted, disorganized, and in groups of twenty or less. That's a fight we can win."
Rowan scratched his chin. "Boss. That's a lot of digging."
"It's four days of digging."
"We have four days?"
Nyxara nodded. "My scouts estimate the Crimson Fang is assembling at Baron Graves' estate. Four days' march from here, at their pace with the siege wagon."
[QUEST ACTIVATED]
[Defend Ashenmere: Phase 2]
[Enemy force: ~200 (Crimson Fang
mercenary company + cavalry + siege)]
[Estimated survival probability: 22%]
[Recommendation: Strategic withdrawal.
Current domain can be rebuilt
elsewhere with reduced losses.]
[Note: This recommendation has been
generated 14 times for previous
Contractors. It was accepted 12 times.
The 2 who refused both died.]
Ethan read it. Read it again. Dismissed it with a flick of his eyes.
"We're not running. I didn't build a drainage system and a clinic and a wall just to abandon them."
Lena looked at him. Something shifted in her expression. Not relief. Something deeper.
"You're crazy," Rowan said.
"I'm an engineer. We don't abandon infrastructure."

Greta came back at dusk. She moved through the gate without a sound, which was impressive for someone her size. Ash dust in her hair, mud on her boots, and a grin that showed too many teeth.
"Four days," she confirmed. "Moving slow. The siege wagon has a broken axle they keep repairing. Cavalry's spread wide -- scouts on the flanks, main body in a column."
"Formation?"
"Loose. They're not expecting a fight until they get here. Officers ride in the middle. Lazy." She pulled a stick from her belt and scratched lines in the dirt floor. "But I found something better. West of here, maybe two kilometers. A canyon."
Everyone looked at the crude map she was drawing.
"Narrow. Stone walls on both sides, fifty meters high. A river runs through the bottom. One way in from the north, one way out to the south. The cavalry can't fit more than four abreast."
Ethan was already calculating. Canyon walls at fifty meters. River at the base. One-way flow. Narrow passage. His brain lit up like a switchboard.
"How wide at the narrowest point?"
"Maybe ten meters. Twelve at most."
"And the river?"
"Shallow right now. Ankle deep. But there's a bend upstream where the water pools before it drops into the canyon. Big pool. Deep."
Ethan stared at the scratched lines. Then he looked up. The grin on his face made Rowan take a step back.
"We need to dam the river."
Silence.
Nyxara's eyes narrowed. "You want to flood a canyon."
"I want to flood a canyon full of mercenaries. There's a difference."
"How much water?"
"If the upstream pool is as deep as she says -- three thousand cubic meters, give or take. That's three million liters dropping through a ten-meter-wide channel." He looked at his own sketch and his grin widened. "That's enough to turn a canyon into a river in about forty-five seconds."
Rowan's face went through several expressions. Horror. Disbelief. A grudging sort of awe. Then it settled on the one Ethan was used to seeing.
"Boss. That's evil."
"It's hydraulic engineering."
Rowan looked at Nyxara. "He's getting worse."
Nyxara studied the map. Her violet eyes traced the canyon, the river, the upstream pool. She was seeing what Ethan saw -- the geometry of destruction mapped onto terrain like a blueprint.
"It could work," she said. "If you can build a dam in four days."
"Three days for the dam. One day for everything else."
"And if the dam fails?"
"Then we're back to fighting two hundred soldiers with twenty farmers." He rolled up his sketches. "So let's make sure the dam doesn't fail."
Greta was watching him. Her amber eyes had that look again -- the same one from the kill box tour. Evaluation. Reassessment. Like she kept having to update her file on what a human was capable of.
"You're small," she said. "You're weak. You can't track, you can't hunt, and I could snap you in half without trying."
"Thanks for the summary."
"But you think like a predator." Her tail moved. Once. "I'll help build your dam."
Ethan met her eyes. "Welcome to the construction crew."

That night, Ethan sat alone with his blueprints and a stub of charcoal. The dam design took shape under his hands -- a timber-and-earth structure across the river's narrowing point, with a release mechanism built into the base. One lever. One chain. One log holding back a lake.
Simple. The best engineering always was. His old professor used to say that -- Dr. Mercer, structural dynamics, Tuesday and Thursday mornings. "If your design needs a paragraph to explain, redesign it." Ethan hadn't thought about Dr. Mercer in years. Funny what came back to you when you were planning mass casualties.
He sketched the funnel approaches. The pit lines. The oil channels he'd dig along the canyon entrance to light when the mercenaries were halfway through. The barricades that would force them into the canyon like cattle into a chute.
He thought about three thousand cubic meters of water dropping on a hundred men in a stone corridor. The math was clean. The physics was simple. Gravity didn't negotiate. Water didn't care about mercy or morality or the fact that some of those men probably had families.
He thought about it for a long time. His charcoal hovered over the page, leaving a small dark spot where his hand had stopped.
Then he kept drawing.
