As dawn approached, the party shifted entirely into the acorporeal. People took on fancy dress from myth or xenology, or just joked and played with their illusory bodies. It was all very calm and gentle, nothing like the surreal excesses she remembered from her youth, but Leila still felt a tinge of vertigo. When her son Khalid made his ears grow and spin, this amiable silliness carried a hard message: the machinery of the house had ripped her mind from her body, as seamlessly as ever, but this time she would never be returning to the same flesh.
Sunrise brought the first of the goodbyes. Leila forced herself to release each proffered hand, to unwrap her arms from around each non-existent body. She whispered to Jasim, “Are you going mad, too?”
“Of course.”
Gradually the crowd thinned out. The wing grew quiet. Leila found herself pacing from room to room, as if she might yet chance upon someone who’d stayed behind, then she remembered urging the last of them to go, her children and friends tearfully retreating down the hall. She skirted inconsolable sadness, then lifted herself above it and went looking for Jasim.
He was waiting for her outside their room.
“Are you ready to sleep?” he asked her gently.
She said, “For an eon.”

Leila woke in the same bed as she’d lain down in. Jasim was still sleeping beside her. The window showed dawn, but it was not the usual view of the cliffs and the ocean.
Leila had the house brief her. After twenty thousand years – traveling more or less at lightspeed, pausing only for a microsecond or two at various way-stations to be cleaned up and amplified – the package of information bearing the two of them had arrived safely at Nazdeek-be-Beegane. This world was not crowded, and it had been tweaked to render it compatible with a range of metabolic styles. The house had negotiated a site where they could live embodied in comfort if they wished.
Jasim stirred and opened his eyes. “Good morning. How are you feeling?”
“Older.”
“Really?”
Leila paused to consider this seriously. “No. Not even slightly. How about you?”
“I’m fine. I’m just wondering what’s out there.” He raised himself up to peer through the window. The house had been instantiated on a wide, empty plain, covered with low stalks of green and yellow vegetation. They could eat these plants, and the house had already started a spice garden while they slept. He stretched his shoulders. “Let’s go and make breakfast.”
They went downstairs, stepping into freshly minted bodies, then out into the garden. The air was still, the sun already warm. The house had tools prepared to help them with the harvest. It was the nature of travel that they had come empty-handed, and they had no relatives here, no fifteenth cousins, no friends of friends. It was the nature of the Amalgam that they were welcome nonetheless, and the machines that supervised this world on behalf of its inhabitants had done their best to provide for them.
“So this is the afterlife,” Jasim mused, scything the yellow stalks. “Very rustic.”
“Speak for yourself,” Leila retorted. “I’m not dead yet.” She put down her own scythe and bent to pluck one of the plants out by its roots.
The meal they made was filling but bland. Leila resisted the urge to tweak her perceptions of it; she preferred to face the challenge of working out decent recipes, which would make a useful counterpoint to the more daunting task they’d come here to attempt.
They spent the rest of the day just tramping around, exploring their immediate surroundings. The house had tapped into a nearby stream for water, and sunlight, stored, would provide all the power they needed. From some hills about an hour’s walk away they could see into a field with another building, but they decided to wait a little longer before introducing themselves to their neighbors. The air had a slightly odd smell, due to the range of components needed to support other metabolic styles, but it wasn’t too intrusive.
The onset of night took them by surprise. Even before the sun had set a smattering of stars began appearing in the east, and for a moment Leila thought that these white specks against the fading blue were some kind of exotic atmospheric phenomenon, perhaps small clouds forming in the stratosphere as the temperature dropped. When it became clear what was happening, she beckoned to Jasim to sit beside her on the bank of the stream and watch the stars of the bulge come out.
They’d come at a time when Nazdeek lay between its sun and the galactic center. At dusk one half of the Aloof’s dazzling territory stretched from the eastern horizon to the zenith, with the stars’ slow march westward against a darkening sky only revealing more of their splendor.
“You think that was to die for?” Jasim joked as they walked back to the house.
“We could end this now, if you’re feeling unambitious.”
He squeezed her hand. “If this takes ten thousand years, I’m ready.”
It was a mild night, they could have slept outdoors, but the spectacle was too distracting. They stayed downstairs, in the physical wing. Leila watched the strange thicket of shadows cast by the furniture sliding across the walls. These neighbors never sleep, she thought. When we come knocking, they’ll ask what took us so long.

Hundreds of observatories circled Nazdeek, built then abandoned by others who’d come on the same quest. When Leila saw the band of pristine space junk mapped out before her – orbits scrupulously maintained and swept clean by robot sentinels for eons – she felt as if she’d found the graves of their predecessors, stretching out in the field behind the house as far as the eye could see.
Nazdeek was prepared to offer them the resources to loft another package of instruments into the vacuum if they wished, but many of the abandoned observatories were perfectly functional, and most had been left in a compliant state, willing to take instructions from anyone.
Leila and Jasim sat in their living room and woke machine after machine from millennia of hibernation. Some, it turned out, had not been sleeping at all, but had been carrying on systematic observations, accumulating data long after their owners had lost interest.
In the crowded stellar precincts of the bulge, disruptive gravitational effects made planet formation rarer than it was in the disk, and orbits less stable. Nevertheless, planets had been found. A few thousand could be tracked from Nazdeek, and one observatory had been monitoring their atmospheric spectra for the last twelve millennia. In all of those worlds for all of those years, there were no signs of atmospheric composition departing from plausible, purely geochemical models. That meant no wild life, and no crude industries. It didn’t prove that these worlds were uninhabited, but it suggested either that the Aloof went to great lengths to avoid leaving chemical fingerprints, or they lived in an entirely different fashion to any of the civilizations that had formed the Amalgam.
Of the eleven forms of biochemistry that had been found scattered around the galactic disk, all had given rise eventually to hundreds of species with general intelligence. Of the multitude of civilizations that had emerged from those roots, all contained cultures that had granted themselves the flexibility of living as software, but they also all contained cultures that persisted with corporeal existence. Leila would never have willingly given up either mode, herself, but while it was easy to imagine a subculture doing so, for a whole species it seemed extraordinary. In a sense, the intertwined civilization of the Amalgam owed its existence to the fact that there was as much cultural variation within every species as there was between one species and another. In that explosion of diversity, overlapping interests were inevitable.
If the Aloof were the exception, and their material culture had shrunk to nothing but a few discreet processors – each with the energy needs of a gnat, scattered throughout a trillion cubic light years of dust and blazing stars – then finding them would be impossible.
Of course, that worst-case scenario couldn’t quite be true. The sole reason the Aloof were assumed to exist at all was the fact that some component of th
eir material culture was tossing back every probe that was sent into the bulge. However discreet that machinery was, it certainly couldn’t be sparse: given that it had managed to track, intercept and reverse the trajectories of billions of individual probes that had been sent in along thousands of different routes, relativistic constraints on the information flow implied that the Aloof had some kind of presence at more or less every star at the edge of the bulge.
Leila and Jasim had Nazdeek brief them on the most recent attempts to enter the bulge, but even after forty thousand years the basic facts hadn’t changed. There was no crisply delineated barrier marking the Aloof’s territory, but at some point within a border region about fifty light years wide, every single probe that was sent in ceased to function. The signals from those carrying in-flight beacons or transmitters went dead without warning. A century or so later, they would appear again at almost the same point, traveling in the opposite direction: back to where they’d come from. Those that were retrieved and examined were found to be unharmed, but their data logs contained nothing from the missing decades.
Jasim said, “The Aloof could be dead and gone. They built the perfect fence, but now it’s outlasted them. It’s just guarding their ruins.”
Leila rejected this emphatically. “No civilization that’s spread to more than one star system has ever vanished completely. Sometimes they’ve changed beyond recognition, but not one has ever died without descendants.”
“That’s a fact of history, but it’s not a universal law,” Jasim persisted. “If we’re going to argue from the Amalgam all the time, we’ll get nowhere. If the Aloof weren’t exceptional, we wouldn’t be here.”
“That’s true. But I won’t accept that they’re dead until I see some evidence.”
“What would count as evidence? Apart from a million years of silence?”
Leila said, “Silence could mean anything. If they’re really dead, we’ll find something more, something definite.”
“Such as?”
“If we see it, we’ll know.”
They began the project in earnest, reviewing data from the ancient observatories, stopping only to gather food, eat and sleep. They had resisted making detailed plans back on Najib, reasoning that any approach they mapped out in advance was likely to be rendered obsolete once they learned about the latest investigations. Now that they’d arrived and found the state of play utterly unchanged, Leila wished that they’d come armed with some clear options for dealing with the one situation they could have prepared for before they’d left.
In fact, though they might have felt like out-of-touch amateurs back on Najib, now that the Aloof had become their entire raison d’être it was far harder to relax and indulge in the kind of speculation that might actually bear fruit, given that every systematic approach had failed. Having come twenty thousand light years for this, they couldn’t spend their time day-dreaming, turning the problem over in the backs of their minds while they surrendered to the rhythms of Nazdeek’s rural idyll. So they studied everything that had been tried before, searching methodically for a new approach, hoping to see the old ideas with fresh eyes, hoping that – by chance if for no other reason – they might lack some crucial blind spot that had afflicted all of their predecessors.
After seven months without results or inspiration, it was Jasim who finally dragged them out of the rut. “We’re getting nowhere,” he said. “It’s time to accept that, put all this aside, and go visit the neighbors.”
Leila stared at him as if he’d lost his mind. “Go visit them? How? What makes you think that they’re suddenly going to let us in?”
He said, “The neighbors. Remember? Over the hill. The ones who might actually want to talk to us.”

Their neighbors had published a précis stating that they welcomed social contact in principle, but might take a while to respond. Jasim sent them an invitation, asking if they’d like to join them in their house, and waited.
After just three days, a reply came back. The neighbors did not want to put them to the trouble of altering their own house physically, and preferred not to become acorporeal at present. Given the less stringent requirements of Leila and Jasim’s own species when embodied, might they wish to come instead to the neighbors’ house?
Leila said, “Why not?” They set a date and time.
The neighbors’ précis included all the biological and sociological details needed to prepare for the encounter. Their biochemistry was carbon-based and oxygen-breathing, but employed a different replicator to Leila and Jasim’s DNA. Their ancestral phenotype resembled a large furred snake, and when embodied they generally lived in nests of a hundred or so. The minds of the individuals were perfectly autonomous, but solitude was an alien and unsettling concept for them.
Leila and Jasim set out late in the morning, in order to arrive early in the afternoon. There were some low, heavy clouds in the sky, but it was not completely overcast, and Leila noticed that when the sun passed behind the clouds, she could discern some of the brightest stars from the edge of the bulge.
Jasim admonished her sternly, “Stop looking. This is our day off.”
The Snakes’ building was a large squat cylinder resembling a water tank, which turned out to be packed with something mossy and pungent. When they arrived at the entrance, three of their hosts were waiting to greet them, coiled on the ground near the mouth of a large tunnel emerging from the moss. Their bodies were almost as wide as their guests’, and some eight or ten meters long. Their heads bore two front-facing eyes, but their other sense organs were not prominent. Leila could make out their mouths, and knew from the briefing how many rows of teeth lay behind them, but the wide pink gashes stayed closed, almost lost in the gray fur.
The Snakes communicated with a low-frequency thumping, and their system of nomenclature was complex, so Leila just mentally tagged the three of them with randomly chosen, slightly exotic names – Tim, John and Sarah – and tweaked her translator so she’d recognize intuitively who was who, who was addressing her, and the significance of their gestures.
“Welcome to our home,” said Tim enthusiastically.
“Thank you for inviting us,” Jasim replied.
“We’ve had no visitors for quite some time,” explained Sarah. “So we really are delighted to meet you.”
“How long has it been?” Leila asked.
“Twenty years,” said Sarah.
“But we came here for the quiet life,” John added. “So we expected it would be a while.”
Leila pondered the idea of a clan of a hundred ever finding a quiet life, but then, perhaps unwelcome intrusions from outsiders were of a different nature to family dramas.
“Will you come into the nest?” Tim asked. “If you don’t wish to enter we won’t take offense, but everyone would like to see you, and some of us aren’t comfortable coming out into the open.”
Leila glanced at Jasim. He said privately, “We can push our vision to IR. And tweak ourselves to tolerate the smell.”
Leila agreed.
“Okay,” Jasim told Tim.
Tim slithered into the tunnel and vanished in a quick, elegant motion, then John motioned with his head for the guests to follow. Leila went first, propelling herself up the gentle slope with her knees and elbows. The plant the Snakes cultivated for the nest formed a cool, dry, resilient surface. She could see Tim ten meters or so ahead, like a giant glow-worm shining with body heat, slowing down now to let her catch up. She glanced back at Jasim, who looked even weirder than the Snakes now, his face and arms blotched with strange bands of radiance from the exertion.
After a few minutes, they came to a large chamber. The air was humid, but after the confines of the tunnel it felt cool and fresh. Tim led them toward the center, where about a dozen other Snakes were already waiting to greet them. They circled the guests excitedly, thumping out a delighted welcome. Leila felt a surge of adrenaline; she knew that she and Jasim were in no danger, but the sheer size and energy
of the creatures was overwhelming.
“Can you tell us why you’ve come to Nazdeek?” asked Sarah.
“Of course.” For a second or two Leila tried to maintain eye contact with her, but like all the other Snakes she kept moving restlessly, a gesture that Leila’s translator imbued with a sense of warmth and enthusiasm. As for lack of eye contact, the Snakes’ own translators would understand perfectly that some aspects of ordinary, polite human behavior became impractical under the circumstances, and would not mislabel her actions. “We’re here to learn about the Aloof,” she said.
“The Aloof?” At first Sarah just seemed perplexed, then Leila’s translator hinted at a touch of irony. “But they offer us nothing.”
Leila was tongue-tied for a moment. The implication was subtle but unmistakable. Citizens of the Amalgam had a protocol for dealing with each other’s curiosity: they published a précis, which spelled out clearly any information that they wished people in general to know about them, and also specified what, if any, further inquiries would be welcome. However, a citizen was perfectly entitled to publish no précis at all and have that decision respected. When no information was published, and no invitation offered, you simply had no choice but to mind your own business.
“They offer us nothing as far as we can tell,” she said, “but that might be a misunderstanding, a failure to communicate.”
“They send back all the probes,” Tim replied. “Do you really think we’ve misunderstood what that means?”
