In the moonlight the antenna was a single dark flower rising from the broad back of the bladder. Naqi started moving along the railed catwalk that led to it, steadying herself as she went but feeling much less vertigo than would have been the case in daylight.
Then she froze, certain that she was being watched.
Just within Naqi’s peripheral vision appeared a messenger sprite. It had flown to the height of the airship and was now shadowing it from a distance of ten or twelve metres. Naqi gasped, delighted and unnerved at the same time. Apart from dead specimens this was the first time Naqi had ever seen a sprite this close. The organism had the approximate size and morphology of a terrestrial hummingbird, yet it glowed like a lantern. Naqi recognised it immediately as a long-range packet carrier. Its belly would be stuffed with data coded into tightly packed wads of RNA, locked within microscopic protein capsomeres. The packet carrier’s head was a smooth teardrop, patterned with luminous pastel markings, but lacking any other detail save for two black eyes positioned above the midline. Inside the head was a cluster of neurones, which encoded the positions of the brightest circumpolar stars. Other than that, sprites had only the most rudimentary kind of intelligence. They existed to shift information between nodal points in the ocean when the usual chemical signalling pathways were deemed too slow or imprecise. The sprite would die when it reached its destination, consumed by microscopic organisms that would unravel and process the information stored in the capsomeres.
And yet Naqi had the acute impression that it was watching her: not just the airship, but her, with a kind of watchful curiosity that made the hairs on the back of her neck bristle. And then — just at the point when the feeling of scrutiny had become unsettling — the sprite whipped sharply away from the airship. Naqi watched it descend back towards the ocean and then coast above the surface, bobbing now and then like a skipping stone. She remained still for several more minutes, convinced that something of significance had happened, though aware too of how subjective the experience had been; how unimpressive it would seem if she tried to explain it to Mina tomorrow. Anyway, Mina was the one with the special bond with the ocean, wasn’t she? Mina was the one who scratched her arms at night; Mina was the one who had too high a conformal index to be allowed into the swimmer corps. It was always Mina.
It was never Naqi.
The antenna’s metre-wide dish was anchored to a squat plinth inset with weatherproofed controls and readouts. It was century-old Pelican technology, like the airship and the fan. Many of the controls and displays were dead, but the unit was still able to lock onto the functioning satellites. Naqi flicked open the fan and copied the latest feeds into the fan’s remaining memory. Then she knelt down next to the plinth, propped the fan on her knees and sifted through the messages and news summaries of the last day. A handful of reports had arrived from friends in Prachuap-Pangnirtung and Umingmaktok snowflake cities, another from an old boyfriend in the swimmer corps station on Narathiwat atoll. He had sent her a list of jokes that were already in wide circulation. She scrolled down the list, grimacing more than grinning, before finally managing a half-hearted chuckle at one that had previously escaped her. Then there were a dozen digests from various special interest groups related to the Jugglers, along with a request from a journal editor that she critique a paper. Naqi skimmed the paper’s abstract and thought that she was probably capable of reviewing it.
She checked through the remaining messages. There was a note from Dr Sivaraksa saying that her formal application to work on the Moat project had been received and was now under consideration. There had been no official interview, but Naqi had met Sivaraksa a few weeks earlier when both of them happened to be in Umingmaktok. Sivaraksa had been in an encouraging mood during the meeting, though Naqi couldn’t say whether that was because she’d given a good impression or because Sivaraksa had just had his tapeworm swapped for a nice new one. But Sivaraksa’s message said she could expect to hear the result in a day or two. Naqi wondered idly how she would break the news to Mina if she was offered the job. Mina was critical of the whole idea of the Moat and would probably take a dim view of her sister having anything to do with it.
Scrolling down further, she read another message from a scientist in Qaanaaq requesting access to some calibration data she had obtained earlier in the summer. Then there were four or five automatic weather advisories, drafts of two papers she was contributing to, and an invitation to attend the amicable divorce of Kugluktuk and Gjoa, scheduled to take place in three weeks’ time. Following that there was a summary of the latest worldwide news — an unusually bulky file — and then there was nothing. No further messages had arrived for eight hours.
There was nothing particularly unusual about that — the ailing network was always going down — but for the second time that night the back of Naqi’s neck tingled. Something must have happened, she thought.
She opened the news summary and started reading. Five minutes later she was waking Mina.
‘I don’t think I want to believe it,’ Mina Okpik said.
Naqi scanned the heavens, dredging childhood knowledge of the stars. With some minor adjustment to allow for parallax, the old constellations were still more or less valid when seen from Turquoise.
‘That’s it, I think.’
‘What?’ Mina said, still sleepy.
Naqi waved her hand at a vague area of the sky, pinned between Scorpius and Hercules. ‘Ophiuchus. If our eyes were sensitive enough, we’d be able to see it now: a little prick of blue light.’
‘I’ve had enough of little pricks for one lifetime,’ Mina said, tucking her arms around her knees. Her hair was the same pure black as Naqi’s, but trimmed into a severe, spiked crop which made her look younger or older depending on the light. She wore black shorts and a shirt that left her arms bare. Luminous tattoos in emerald and indigo spiralled around the piebald marks of random fungal invasion that covered her arms, thighs, neck and cheeks. The fullness of the moons caused the fungal patterns to glow a little themselves, shimmering with the same emerald and indigo hues. Naqi had no tattoos and scarcely any fungal patterns of her own; she couldn’t help but feel slightly envious of her sister’s adornments.
Mina continued, ‘But seriously, you don’t think it might be a mistake?’
‘I don’t think so, no. See what it says there? They detected it weeks ago, but they kept quiet until now so that they could make more measurements.’
‘I’m surprised there wasn’t a rumour.’
Naqi nodded. ‘They kept the lid on it pretty well. Which doesn’t mean there isn’t going to be a lot of trouble.’
‘Mm. And they think this blackout is going to help?’
‘My guess is official traffic’s still getting through. They just don’t want the rest of us clogging up the network with endless speculation. ’
‘Can’t blame us for that, can we? I mean, everyone’s going to be guessing, aren’t they?’
‘Maybe they’ll announce themselves before very long,’ Naqi said doubtfully.
While they had been speaking the airship had passed into a zone of the sea largely devoid of bioluminescent surface life. Such zones were almost as common as the nodal regions where the network was thickest, like the gaping voids between clusters of galaxies. The wake of the sensor pod was almost impossible to pick out, and the darkness around them was absolute, relieved only by the occasional mindless errand of a solitary messenger sprite.
Mina said: ‘And if they don’t?’
‘Then I guess we’re all in a lot more trouble than we’d like.’
