It was enough, once. Now, ßehemoth has laid so much to waste that even the electromagnetic spectrum is withering into oblivion.

But it's not as though anything's going to attack us in the space of five minutes, she tells herself—

— and in the next instant realizes that something has.

Little telltales are spiking red at the edge of her vision: an overload on Lubin's channel. She ID's his frequency, ready to join him in battle—but before she can act the intruder crashes her own line. Her eyes fill with static: her ears fill with venom.

"Don't you fucking dare try and cut me out, you miserable cocksucking stumpfuck! I'll shred every channel you try and open. I'll sink your whole priestly setup, you maggot-riddled twat!"

"Here we go again." Lubin's voice seems to come from a great distance, some parallel world where long gentle waves slap harmlessly against flesh and machinery. But Clarke is under assault in this world, a vortex of static and swirling motion and—oh God, please not—the beginnings of a face, some hideous simulacrum distorted just enough to be almost unrecognizable.

Clarke dumps a half-dozen buffers. Gigabytes evaporate at her touch. In her eyephones, the monster screams.

"Good," Lubin's tinny voice remarks from the next dimension. "Now if we can just save—"

"You can't save anything!" the apparition screams. "Not a fucking thing! You miserable fetusfuckers, don't you even know who I am?"

Yes, Clarke doesn't say.

"I'm Lenie Clar—"

The headset goes dark.

For a moment she thinks she's still spinning in the vortex. This time, it's only the waves. She pulls the headset from her skull. A moon-pocked sky rotates peacefully overhead.

Lubin's shutting down the receiver. "That's that," he tells her. "We lost eighty percent of the trawl."

"Maybe we could try again." She knows they won't. Surface time follows an unbreakable protocol; paranoia's just good sense these days. And the thing that downloaded into their receiver is still out there somewhere, cruising the airwaves. The last thing they want to do is open that door again.

She reaches out to reel in the antennae cluster. Her hand trembles in the moonlight.

Lubin pretends not to notice. "Funny," he remarks, "it didn't look like you."

After all these years, he still doesn't know her at all.

They should not exist, these demons that have taken her name. Predators that wipe out their prey don't last long. Parasites that kill their hosts go extinct. It doesn't matter whether wildlife is built from flesh or electrons, Clarke's been told; the same rules apply. They've encountered several such monsters over the past months, all of them far too virulent for evolutionary theory.

Maybe they just followed my lead, she reflects.Maybe they keep going on pure hate.

They leave the moon behind. Lubin dives headfirst, pointing his squid directly into the heart of darkness. Clarke lingers a bit, content to drift down while Luna wriggles and writhes and fades above her. After a while the moonlight loses its coherence, smears across the euphotic zone in a diffuse haze, no longer illuminates the sky but rather becomes it. Clarke nudges the throttle and gives herself back to the depths.

By the time she catches up with Lubin the ambient light has failed entirely; she homes in on a greenish pinpoint glow that resolves into the dashboard of her companion's squid. They continue their descent in silent tandem. Pressure masses about them. Eventually they pass the perimeter checkpoint, an arbitrary delimiter of friendly territory. Clarke trips her LFAM to call in.

No one answers.

It's not that no one's online. The channel's jammed with voices, some vocoded, some airborne, overlapping and interrupting. Something's happened. An accident. Atlantis demands details. Mechanical rifter voices call for medics at the eastern airlock.

Lubin sonars the abyss, gets a reading. He switches on his squidlight and peels down to port. Clarke follows.

A dim constellation traverses the darkness ahead, barely visible, fading. Clarke throttles up to keep pace; the increased drag nearly peels her off the squid. She and Lubin close from above and behind.

Two trailing squids, slaved to a third in the lead, race along just above the seabed. One of the slaves moves riderless. The other drags a pair of interlinked bodies through the water. Clarke recognizes Hannuk Yeager, his left arm stretched almost to dislocation as he grips his towbar one-handed. His other hooks around the chest of a black rag doll, life-size, a thin contrail of ink swirling in the wake of its passage.

Lubin crosses to starboard. The contrail flushes crimson in his squidlight.

Erickson, Clarke realizes. Out on the seabed, a dozen familiar cues of posture and motion distinguish one person from another; rifters only look alike when they're dead. It's not a good sign that she's had to fall back on Erickson's shoulder tag for an ID.

Something's ripped his diveskin from crotch to armpit; something's ripped him, underneath it. It looks bad. Mammalian flesh clamps tight in ice-water, peripheral blood-vessels squeeze down to conserve heat. A surface cut wouldn't bleed at 5 °C. Whatever got Erickson, got him deep.

Grace Nolan's on the lead squid. Lubin takes up position just behind and to the side, a human breakwater to reduce the drag clawing at Erickson and Yeager. Clarke follows his lead. Erickson's vocoder tic-tic-tics with pain or static.

"What happened?" Lubin buzzes.

"Not sure." Nolan keeps her face forward, intent on navigation. "We were checking out an ancillary seep over by the Lake. Gene wandered around an outcropping and we found him like this a few minutes later. Maybe he got careless under an overhang, something tipped over on him."

Clarke turns her head sideways for a better view; the muscles in her neck tighten against the added drag. Erickson's flesh, exposed through the tear in his diveskin, is fish-belly white. It looks like gashed, bleeding plastic. His capped eyes look even deader than the flesh beneath his 'skin. He gibbers. His vocoder cobbles nonsense syllables together as best it can.

An airborne voice takes the channel. "Okay, we're standing by at Four."

The abyss ahead begins to brighten: smudges of blue-gray light emerge from the darkness, their vertices hinting at some sprawled structure in the haze behind. The squids cross a power conduit snaking along the basalt; its blinking telltales fade to black on either side. The lights ahead intensify, expand to diffuse haloes suffusing jumbled Euclidean silhouettes.

Atlantis resolves before them.

A couple of rifters wait at Airlock Four, chaperoned by a pair of corpses lumbering about in the preshmesh armor that drybacks wear when they venture outside. Nolan cuts power to the squids. Erickson raves weakly in the ensuing silence as the convoy coasts to rest. The corpses take custody, maneuver the casualty towards the open hatch. Nolan starts after them.

One of the corpses blocks her with a gauntleted forearm. "Just Erickson."

"What are you talking about?" Nolan buzzes.

"Medbay's crowded enough as it is. You want him to live, give us room to work."

"Like we're going to trust his life to you lot? fuck that." Most of the rifters have long since had their fill of revenge by now, grown almost indifferent to their own grudges. Not Grace Nolan. Five years gone and still the hatred sucks at her tit like some angry, insatiable infant.

The corpse shakes his head behind the faceplate. "Look, you have to—"

"No sweat," Clarke cuts in. "We can watch on the monitor."

Nolan, countermanded, looks at Clarke. Clarke ignores her. "Go on," she buzzes at the corpses. "Get him inside."
