Chapter Twenty-Nine Blue Vault
CHAPTER TWENTY-NINE
Blue Vault
Blue Vault was not blue.
It was gray concrete built into a canyon wall so completely the entrance looked like a shadow.
Sabra had reached it first.
Two Tollhouse trucks blocked the road.
A third sat at the gate.
Riders had dragged steel barricades across the canyon.
Eden stopped the convoy behind a bend.
Pressure clock: nine hours.
Distance to gate: half a mile.
Rhett studied the canyon through binoculars.
"Fifteen people."
"More in the vault."
"Probably."
Eden did not tease him.
"Other exits?" Mina asked.
Eden unfolded her hand-drawn copy of Caro's west line.
"Maintenance shaft on top."
"Climb?"
"Two hundred feet."
Esme looked up at the cliff.
"No."
Pax said, "I can."
Everyone ignored him.
Rhett traced the road.
"Tollhouse expects a convoy assault."
"Yes."
"What don't they expect?"
Eden stared at the canyon.
Water infrastructure.
Blue Vault's relief gate sat behind the wall.
The road itself crossed an old flood channel.
If the reservoir pressure could be vented early, even partially, the dry channel would become water.
But controls were inside.
Unless.
Eden looked at Pax.
"You still have the pump rig?"
"Captured Tollhouse one?"
"Yes."
"On cargo six."
"Can it reverse?"
Pax frowned.
"Pump water backward?"
"Pressure air."
His face brightened.
Rhett saw it and groaned.
"Never make that face around machinery."
Pax ran toward the rear vehicles.
Eden explained.
The pump rig could feed compressed air into an old inspection line exposed three hundred yards east. If the pneumatic relief system still connected to Blue Vault, pressure might move the emergency gate a fraction.
Not enough to stabilize the reservoir.
Enough to send water into the dry flood channel.
Enough to cut the road between Tollhouse positions.
Mina smiled.
"I like her."
Rhett looked at Eden.
"Already knew."
They moved quietly.
Pax and three mechanics dragged hose to the inspection cap.
Eden found the correct line by its blue ceramic ring.
They connected.
The pump engine started behind rock.
Tollhouse heard.
Shots came over the bend.
Everyone took cover.
"Pressure!" Eden shouted.
Pax increased throttle.
The hose jumped.
Nothing.
"More."
"Line may burst!"
"More."
Rhett watched the canyon mouth.
Tollhouse riders advanced.
Mina fired.
Glass Road answered.
The old factions' gunfire overlapped.
No one cared who covered whom.
Pax pushed the pump.
A deep thud came from inside the canyon wall.
Then another.
Eden smiled.
"Again!"
He pushed.
The ground vibrated.
Far ahead, something opened.
Water appeared under the barricade.
Not a river.
A dark line.
Then a surge.
Cold reservoir water rushed into the dry channel, spreading across the road.
Tollhouse shouted.
A bike toppled.
The advancing riders scrambled back.
The road between front and rear Tollhouse positions became three feet of moving water.
"Now," Rhett said.
Dustline and Glass Road vehicles surged around the bend.
Not through the flood.
To the near barricade.
They hit the isolated Tollhouse front line together.
The fight lasted six minutes.
Rhett hated every second.
No glory.
No clean choreography.
People slipped in water, fired too close, shouted names, and tried not to hit the wrong bodies.
Sabra's front guards surrendered when they realized the rear force could not cross.
Eden did not wait.
She took the blue key and ran for the vault's side stair.
Rhett followed.
"Shoulder," she shouted.
"Shut up."
"Ribs."
"Later."
They climbed.
At the top, a narrow maintenance door waited.
The real key turned.
Blue Vault opened.
Inside, the sound of water was enormous.
Gauges lined the wall.
Every pressure needle sat in red.
Nine hours had become less.
Eden found the relief gate wheel.
Locked.
A chain ran through it.
New chain.
Sabra.
Rhett raised the captured rifle.
"No."
Eden pointed to the lock.
"Ricochet."
He lowered it.
"Tool?"
They had none.
Eden looked at the blue key.
Then the chain.
Then a maintenance lever mounted on the wall.
She pulled the lever free.
Rhett smiled.
"Everything is a machine."
"Disrespectfully."
They wedged the lever through the chain.
Together they pulled.
Metal strained.
The chain held.
Below, a gunshot echoed.
Then Sabra's voice came through the vault intercom.
"Eden."
Of course there was an intercom.
Eden looked at the speaker.
Sabra continued.
"You open that gate, you flood the west channel."
"That's the purpose."
"You flood three Tollhouse camps."
Eden froze.
Rhett stared at the speaker.
"People?"
"Seventy-four."
Sabra's voice remained calm.
"Families too."
The lever in Eden's hands suddenly weighed more.
Rhett closed his eyes.
Of course.
Nothing simple.
Never.
Sabra said, "Close Saint Mercy instead. Let the reservoir equalize naturally."
Eden looked at the gauges.
"How long?"
"Two days."
"The gorge wall fails first."
"Maybe."
Sabra used the word like a knife.
Rhett stepped to the intercom.
"Evacuate the camps."
"Nine hours."
"Less."
"Vehicles are here."
Eden understood.
Sabra had brought the Tollhouse trucks to Blue Vault.
Her camps had limited transport.
If they opened the gate fully, the flood channel became lethal downstream.
If they did not, Reservoir Three could rupture.
Not a villain's trick.
A real consequence.
Rhett looked at Eden.
"Can we stage it?"
Her mind moved.
Gate opening.
Flow rate.
Channel distance.
Old spill diagram.
"Partial."
"Enough?"
"Maybe."
He almost smiled.
She didn't.
"We open ten percent. Pressure drops slowly. Tollhouse radios evacuation."
Sabra's voice came through.
"And if ten isn't enough?"
"Then we increase after camps clear."
Silence.
Sabra asked, "Why should I trust you?"
Eden looked at the chain.
"You shouldn't."
She wedged the lever again.
"You should watch the gauge."
Rhett pulled with her.
The chain snapped.
