Starfish

She wriggles forward. There's a sudden roaring, and for one paralyzed moment she thinks the smoker is starting to blow. But the roar is in her head; something's plugging her electrolyser intake, depriving her of oxygen. It's only Lenie Clarke, passing out.

She shakes back and forth, a spasm centimeters in amplitude. It's enough; her intake is clear again. And as an added bonus, she's gotten far enough to see around the corner.

Acton's boiled skeleton clogs the passageway, crusty with mineral deposits. Blobs of melted copolymer stick to the remains like old candle wax. Somewhere in there, at least one piece of human technology is still working, screaming back to Beebe's deafened sensors.

She can't reach him. She can barely even touch him. But somehow, even through the encrustations, she can see that his neck has been neatly snapped.

Reptile

It has forgotten what it was.

Not that that matters, down here. What good is a name when there's nothing around to use it? This one doesn't remember where it comes from. It doesn't remember the ones that drove it out so long ago. It doesn't remember the overlord that once sat atop its spinal cord, that gelatinous veneer of language and culture and denied origins. It doesn't even remember the slow deterioration of that oppressor, its final dissolution into dozens of autonomous, squabbling subroutines. Now even those have fallen silent.

Not much comes down from the cortex any more. Low-level impulses flicker in from the parietal and occipital lobes. The motor strip hums in the background. Occasionally, Broca's area mutters to itself. The rest is mostly dead and dark, worn smooth by a black ocean hot and mercurial as live steam, cold and sluggish as antifreeze. All that's left now is pure reptile.

It pushes on, blind and unthinking, oblivious to the weight of four hundred liquid atmospheres. It eats whatever it can find, somehow knowing what to avoid and what to consume. Desalinators and recyclers keep it hydrated. Sometimes, old mammalian skin grows sticky with secreted residues; newer skin, laid on top, opens pores to the ocean and washes everything clean with aliquots of distilled sea water.

It's dying, of course, but slowly. It wouldn't care much about that, even if it knew.

Like all living things, it has a purpose. It is a guardian. It forgets, sometimes, exactly what it is supposed to be protecting. No matter. It knows it when it sees it.

It sees her now, crawling from a hole in the bottom of the world. She looks much like the others, but it has always been able to tell the difference. Why protect her, and not the others? It doesn't care. Reptiles never question motives. They only act on them.

She doesn't seem to know that it is here, watching.

The reptile is privy to certain insights that should, by rights, be denied it. It was exiled before the others tweaked their neurochemistry into more sensitive modes. And yet all that those changes did, in the end, was to make certain weak signals more easily discernible against a loud and chaotic background. Since the reptile's cortex shut down, background noise has been all but silenced. The signals are as weak as ever, but the static has disappeared. And so the reptile has, without realizing it, absorbed a certain muddy awareness of distant attitudes.

It feels, somehow, that this place has become dangerous, although it doesn't know how. It feels that the other creatures have disappeared. And yet, the one it protects is still here. With far less comprehension than a mother cat relocating her endangered kittens, the reptile tries to take its charge to safety.

It's easier when she stops struggling. Eventually she even allows it to pull her away from the bright lights, back towards the place she belongs. She makes sounds, strange and familiar; the reptile listens at first, but they make its head hurt. After a while she stops. Silently, the reptile draws her through sightless nightscapes.

Dim light dawns ahead. And sound; faint at first, but growing. A soft whine. Gurgles. And something else, a pinging noise — metallic, Broca murmurs, although it doesn't know what that means.

A copper beacon glares out from the darkness ahead — too coarse, too steady, far brighter than the bioluminescent embers that usually light the way. It turns the rest of the world stark black. The reptile usually avoids this place. But this is where she comes from. This is safety for her, even though to the reptile, it represents something completely —

From the cortex, a shiver of remembrance.

The beacon shines down from several meters above the sea bed. At closer range it resolves into a string of smaller lights stretched in an arc, like photophores on the flank of some enormous fish.

Broca sends down more noise: Sodium floods.
