Wyatt turns from the door. "Say that again."
"Bracken and the water folk and your pack are all drinking from the same well," I tell him. "It's why nothing they harvested worked in a lab. It isn't in the blood. It's in the ground, and you're all standing on the same ground."
The third sheet is the one that decides my future. It's a process diagram for the extraction sequence, and I read it the way you'd read a post-mortem report. There's a note block in the corner, and note four says: Horizon is a closed pressure system. No identified recharge mechanism. Design assumes single-pass depletion.
"Single-pass depletion," Nash repeats.
"They're not harvesting a crop. They're pulling a plug." My voice doesn't sound like mine. "Nash, I'd assumed they'd take some, damage it, and it would recover in decades, that's how everything I've ever studied works. It doesn't recover. There's no recharge. Whatever's down there took whatever time it took to be there, and they intend to draw it in one pass, and the sequence diagram has an end state, and that is empty."
"And when it's empty?"
"Then the pressure differential reverses and the water goes down into the void. Two hundred feet of water into a nine-hundred-meter cavity through fractured rock. It won't be a lake anymore. It'll be a sink. And the fracture system carries that all the way out to Bracken, so the drawdown doesn't stop at the shoreline, it propagates along every one of those arrows."
Wyatt has gone white. "The whole…"
"Everything on that map. All, at once, permanently, with no version where anybody comes back in a hundred years and finds it healing." I start folding sheets into the dry bag. "This isn't a wound. It's an amputation, and they've drawn the diagram."
The gallery starts filling. Wyatt hears it first, a shudder in the pipework, then a valve actuator running somewhere above us. The panel by the door lights up on its own and a pump starts, and cold water begins hitting the sump grating.
"They're filling the loop," I say, already moving. "That's a commissioning fill. Nash, they're charging the cooling system, and you don't charge cooling until the thing it cools is about to run."
The fire door has gone magnetic on lockdown, and the riser hatch is eighty feet up a ladder in a tube that is now taking overflow down its walls. We climb it anyway. My hands slip twice. Wyatt goes ahead and hauls the hatch, and Nash climbs directly beneath me the whole way with a hand braced under my boot at every rung, saying nothing, being exactly where he needs to be.
We come out onto the crib deck into a spotlight sweeping from a patrol boat a quarter mile off, and Caleb has us off the ladder and under a tarp in the bottom of the skiff before the beam reaches us.
I brief them in the yard just before dawn with the drawings weighted down under stones.
"Nine hundred and forty feet, under the drop-off, coil cradled and the cooling loop now charging," I say. "Here's the section. Here's the fracture map, and I'll explain to each of you privately what it means for your own ground, because it isn't only Stillwater. And here's the note that matters."
I read note four aloud. Then I read it again, and the yard goes so quiet I can hear the water. Loon River sits down slowly on the chopping block. Marrow Creek's Alpha puts her hand over her mouth.
"So it's every one of us," Loon River says. "Not neighbors helping neighbors. One body."
"One body," I say.
Nash steps up beside the drawings and puts both hands on the table, and when he speaks the yard turns toward him as a single animal.
"Then nobody's coming as a favor," he says. "Move everything tonight. Boats in the water by ten, the tunnel party staged by midnight, and every person who can fight on this shore by dark."

NASH
At eleven at night I stand at my father's truck and look out to over two hundred people who all know what a fracture map means now.
"Three efforts," I say. "Loon River and Bracken take the tunnel. You're not getting in, you're making them believe the war is ahead of them, and you hold that belief for as long as your people can stand it. Marrow Creek and the Ketterings take the lake-bank vent and hold it open, because that's the road home for everyone who goes under. The water folk take the crib and the patrol boats."
"And you?" Loon River asks.
"Down the riser with Caleb and Erin and four."
"That's seven people between that machine and everything."
"Seven people they won't be looking for, if you're loud enough."
Owen's at the back with his arms folded. He steps up and says the thing an old Alpha is allowed to say and a serving one isn't.
"Anybody wants out, walk now, and there's no shame carried and nobody remembers it."
