ERIN
Ihave ten screens, a stolen binder, and a technician with his hands raised, and I need about four hours of study time, but I've got minutes.
The console is laid out sensibly, which is the only mercy.
Left screen is the draw sequence. Center is the plant mimic, pumps, valves, temperatures, all live and mostly green.
Right is the coil itself: current, field strength, and a bar labeled horizon pressure that is falling in visible increments while I watch.
That bar is what stops my heart. It isn't a rate of production. It's a tank emptying.
"Talk to me," Nash says at my shoulder. He's bleeding from the flank and pretending he isn't.
"Stage two of three. Eighty-one minutes elapsed, and the pressure's down eleven percent already.
" I pull the process diagram out of my jacket and flatten it beside the keyboard.
"Nash, there's no abort. I've been through every menu.
There's a stage advance and there's a hold, and hold just parks it.
It doesn't close the shaft, because they never built a way to close the shaft.
Note four. Single-pass depletion. They designed a thing that has one direction. "
Caleb's at the doorframe, blood down his face. "Then what's on the table?"
"Two options and I hate both." I turn to face them because they deserve it said to their faces. "Option one is I hold the sequence and we spend the next six hours defending this room, and the moment we lose it somebody hits resume. Option two is I break something they can't replace."
The technician says, "You can't overload the coil. It's got a quench protection circuit. It'll trip and dump before you get anywhere near it."
Everyone glances at him. He's about twenty-five and terrified and, I realize, has just given me the answer without meaning to.
"Say that again."
"The… the magnet's superconducting, it's got to be, at that field strength. If it goes normal it dumps its energy and the protection resistors take it. That's why you can't hurt it." He swallows. "It's designed to survive a quench."
"Designed to survive one. Not to survive one badly." I'm already back at the mimic screen, hunting the cryogenics. "Where's the helium plant?"
"Two-forty. Same gallery as the heat rejection."
Three lines on a schematic I have literally stood beside.
"Nash." I put my finger on screen. "The coil's cold because a compressor above our heads keeps it that way, and it dumps its quench energy into a resistor bank cooled by the same chilled-water loop that's running the whole plant.
It survives a quench because two support systems catch it.
Take both away at the same instant and the quench has nowhere to go. "
Caleb says, "What's that mean?"
"It means the coil cooks itself. Windings go, cradle goes, and the field collapses across a twenty-meter opening. And they cannot rebuild it, because that coil came in on a lowboy through a mine tunnel, and it is going to be underneath a considerable amount of lake."
Nash goes very still. "Explain that last part."
"The chamber is so many feet of granite below feet of water, and it's been under stress since they opened the ring.
" I point through the glass. Water is running off the dome in long dark streaks and pooling on the deck.
"That's not condensation, that's inflow.
The rock's already talking. When the field collapses I don't know precisely what the pressure differential does, but I know it does something, and my honest professional opinion is that this chamber floods. "
"How long would we have?"
"Minutes. Maybe. I can't give you a number and I won't pretend to."
Nash doesn't argue and doesn't flinch. He turns to Caleb.
"Get everybody who isn't essential onto the stairwell now. Wyatt, the wounded first, and the technicians go up with them, they're coming out with us."
The kid on the floor starts crying, which I don't have time for. I do the transmission before I do the sabotage, because evidence that never leaves the mountain isn't evidence.
There's a satellite terminal in the corner of the control room and it's live, because these people needed to talk to somebody in a boardroom.
I plug in the drives from the raise and the photographs from the crib and I scan the binder pages on a flatbed that some poor administrator installed down here.
Amelia gets everything. So does the regional EPA criminal enforcement inbox, and the Corps, and two federal addresses Amelia gave me years ago and told me never to use unless I had something real.
I write four lines and nothing more, because the documents do the work.
Unpermitted subsurface excavation beneath a protected waterbody.
Unpermitted industrial extraction, 940 ft below Stillwater Lake.
Falsified geological consignments. Attached: operator's own ecological assessment, their haulage records, and their process diagrams. Their assessment predicts irreversible destruction of the waterbody. Erin Lawson, contract 4471.
The bar crawls. Eleven percent, then forty, then eighty-eight, and the whole time the horizon pressure on the right screen keeps stepping down, and I stand there watching two counters race each other with my hands flat. Sent at 2:41. Nash comes back with the room emptying behind him.
"Everyone's moving. Caleb's got the stairwell." He looks at the displays, then at me. "Tell me what you need."
"Two things at once, or it doesn't work.
" I sketch it behind the process diagram.
"The helium compressor and the chilled-water supply to the resistor bank.
Both on two-forty, both in that gallery, and both have to fail inside the same few seconds or the protection catches it.
Isolate the water first, then kill the compressor, then get out of that room, because the pipework in there will be at operating temperature and it will let go.
That's a plant room job, and it needs somebody who can read a valve tag and somebody strong enough to shut a twelve-inch gate valve fast. I can't do the second part.
You can't do the first. So we do it together, which is, I believe the entire point of the last six weeks. "
Nash actually laughs, which is deranged and exactly right.
"What holds the sequence while we're gone?"
"Nothing. It keeps running." I place my hand on the console. "That's the cost. The draw continues for however long it takes us to reach the two-forty level and do the work. I've thought about it and there's no way around it, because there's nobody left down here I'd trust with either half."
He takes my face in both hands, filthy and bleeding, with a machine turning over a cavity in this world just forty feet away.
"I love you." My voice holds, barely. "And I'm not doing this because I'm brave, and I'm not doing it for science, and I'm certainly not doing it for the state of New York.
There are people up there who are all standing on the same well, and I got to find that out, and now I have to do something about it. That's all it is."
"That's everything it is." He kisses my forehead. "Then we go up, we break it, and we keep going for the riser."
I look one last time at the right-hand display. Horizon pressure, eighty-three percent and stepping down, and stage three flagged to begin in fifty-one minutes.
"Fifty-one minutes," I say. "After that there's no version of where the water stays a lake."
We run for the stairwell together.
