Now Desjardins walked across the landing pad to the edge of the roof. The sun rose from the lip of the precipice as he pissed into space. So many changes, he reflected. So many fold catastrophes in pursuit of new equilibria. His domain had shrunk from a planet to a continent, cauterised at the edges. Eyesight once focused on infinity now ended at the coast. Arms which once encircled the world had been amputated at the elbow. Even N'Am's portion of the Net had been cut from the electronic commons like a tumor; Achilles Desjardins got to deal with the necrotising mess left behind.

And yet, in many ways he had more power than ever. Smaller territory, yes, but so few left to share it with. He was less of a team player these days, more of an emporer. Not that that was widely known…

But some things hadn't changed. He was still technically in the employ of the Complex Systems Instability Response Authority, or whatever vestiges of that organization persisted across the globe. The world had long since fallen on its side—this part of it, anyway—but he was still duty-bound to minimise the damage. Yesterday's brush fires were today's infernos, and Desjardins seriously doubted that anyone could extinguish them at this point; but he was one of the few that might at least be able to keep them contained a little longer. He was still a 'lawbreaker—a lighthouse keepr, as he'd described himself the day they'd finally relented and let him stay behind—and today would be a day like any other. There would be attacks to repel, and enemies to surveil. Some lives would be ended to spare others, more numerous or more valuable. There were virulent microbes to destroy, and appearances to maintain.

He turned his back on the rising sun and stepped over the naked, gutted body of the woman at his feet. Her name had been Alice, too.

He tried to remember if that was only coincidence.

First there is only the sound, in darkness. Drifting on the slope of an undersea mountain, Lenie Clarke resigns herself to the imminent loss of solitude.

She's far enough out for total blindness. Atlantis, with its gantries and beacons and portholes bleeding washed-out light into the abyss, is hundreds of meters behind her. No winking telltales, no conduits or parts caches pollute the darkness this far out. The caps on her eyes can coax light enough to see from the merest sparkle, but they can't create light where none exists. Here, none does. Three thousand meters, three hundred atmospheres, three million kilograms per square meter have squeezed every last photon out of creation. Lenie Clarke is as blind as any dryback.

After five years on the Mid Atlantic Ridge, she still likes it this way.

But now the soft mosquito whine of hydraulics and electricity rises around her. Sonar patters softly against her implants. The whine shifts subtly in pitch, then fades. Faint surge as something coasts to a stop overhead.

"Shit." The machinery in her throat turns the epithet into a soft buzz. "Already?"

"I gave you an extra half-hour." Lubin's voice. His words are fuzzed by the same technology that affects hers; by now the distortion is more familiar than the baseline.

She'd sigh, if breath were possible out here.

Clarke trips her headlamp. Lubin is caught in the ignited beam, a black silhouette studded with subtle implementation. The intake on his chest is a slotted disk, chrome on black. Corneal caps turn his eyes into featureless translucent ovals. He looks like a creature built exclusively from shadow and hardware; Clarke knows of the humanity behind the façade, although she doesn't spread it around.

A pair of squids hover at his side. A nylon bag hangs from one of the meter-long vehicles, lumpy with electronics. Clarke fins over to the other, flips a toggle from slave to manual. The little machine twitches and unfolds its towbar.

On impulse, she kills her headlight. Darkness swallows everything again. Nothing stirs. Nothing twinkles. Nothing attacks.

It's just not the same.

"Something wrong?" Lubin buzzes.

She remembers a whole different ocean, on the other side of the world. Back on Channer Vent you'd turn your lights off and the stars would come out, a thousand bioluminescent constellations: fish lit up like runways at night; glowing arthropods; little grape-sized ctenophores flashing with complex iridescence. Channer sang like a siren, lured all those extravagant midwater exotics down deeper than they swam anywhere else, fed them strange chemicals and turned them monstrously beautiful. Back at Beebe Station, it was only dark when your lights were on.

But Atlantis is no Beebe Station, and this place is no Channer Vent. Here, the only light shines from indelicate, ham-fisted machinery. Headlamps carve arid tunnels through the blackness, stark and ugly as burning sodium. Turn them off, and…nothing.

Which is, of course, the whole point.

"It was so beautiful," she says.

He doesn’t have to ask. "It was. Just don't forget why."

She grabs her towbar. "It's just—it's not the same, you know? Sometimes I almost wish one of those big toothy fuckers would charge out of the dark and try to take a bite out of me…"

She hears the sound of Lubin's squid throttling up, invisibly close. She squeezes her own throttle, prepares to follow him.

The signal reaches her LFAM and her skeleton at the same time. Her bones react with a vibration deep in the jaw: the modem just beeps at her.

She trips her receiver. "Clarke."

"Ken find you okay?" It's an airborne voice, unmutilated by the contrivances necessary for underwater speech.

"Yeah." Clarke's own words sound ugly and mechanical in contrast. "We're on our way up now."

"Okay. Just checking." The voice falls silent for a moment. "Lenie?"

"Still here."

"Just…well, be careful, okay?" Patricia Rowan tells her. "You know how I worry."

The water lightens indiscernibly as they ascend. Somehow their world has changed from black to blue when she wasn't looking; Clarke can never pinpoint the moment when that happens.

Lubin hasn't spoken since Rowan signed off. Now, as navy segues into azure, Clarke says it aloud. "You still don't like her."

"I don't trust her," Lubin buzzes. "I like her fine."

"Because she's a corpse." Nobody has called them corporate executives for years.

"Was a corpse." The machinery in his throat can't mask the grim satisfaction in that emphasis.

"Was a corpse," Clarke repeats.

"No."

"Why, then?"

"You know the list."

She does. Lubin doesn't trust Rowan because once upon a time, Rowan called shots. It was at her command that they were all recruited so long ago, damaged goods damaged further: memories rewritten, motives rewired, conscience itself refitted in the service of some indefinable, indefensible greater good.

"Because she was a corpse," Clarke repeats.

Lubin's vocoder emits something that passes for a grunt.

She knows where he's coming from. To this day, she still isn't certain what parts of her own childhood were real and which were mere inserts, installed after the fact. And she's one of the lucky ones; at least she survived the blast that turned Channer Vent into thirty square kilometers of radioactive glass. At least she wasn't smashed to pulp by the resulting tsunami, or incinerated along with the millions on N'AmPac's refugee strip.

Not that she shouldn't have been, of course. If you want to get technical about it, all those other millions were nothing but collateral. Not their fault—not even Rowan's, really—that Lenie Clarke wouldn't sit still enough to present a decent target.
