But he had been in worse situations, and at least this time there was a distinct hope of success. The bridge on Hela was still there; it had not turned out to be a mirage of the sensors or his own desperate yearning to find something, and the closer he got the less likely it was that the bridge would turn out to be anything other than a genuine technological artefact. Quaiche had seen some deceptive things in his time - geology that looked as if it had been designed, lovingly sculpted or mass-produced - but he had never seen anything remotely like this. His instincts said that geology had not been the culprit, but he was having serious trouble with the question of who - or what - had created it, because the fact remained that 107 Piscium system appeared not to have been visited by anyone else. He shivered in awe, and fear, and reckless expectation.

He felt the indoctrinal virus awaken in his blood, a monster turning over in its sleep, opening one dreamy eye. It was always there, always within him, but for much of the time it slept, disturbing neither his dreams nor his waking moments. When it engorged him, when it roared in his veins like a distant report of thunder, he would see and hear things. He would glimpse stained-glass windows in the sky; he would hear organ music beneath the subsonic growl of each burst of correctional thrust from his tiny jewel-like exploration ship.

Quaiche forced calm. The last thing he needed now was the indoctrinal virus having its way with him. Let it come to him later, when he was safe and sound back aboard the
Dominatrix
. Then it could turn him into any kind of drooling, mumbling idiot it wished. But not here, not now. Not while he needed total clarity of mind.

The monster yawned, returned to sleep.

Quaiche was relieved. His faltering control over the virus was still there.

He let his thoughts creep back to the bridge, cautiously this time, trying to avoid succumbing to the reverential cosmic chill that had wakened the virus.

Could he really rule out human builders? Wherever they went, humans left junk. Their ships spewed out radioisotopes, leaving twinkling smears across the faces of moons and worlds. Their pressure suits and habitats leaked atoms, leaving ghost atmospheres around otherwise airless bodies. The partial pressures of the constituent gases were always a dead giveaway. They left navigation transponders, servitors, fuel cells and waste products. You found their frozen piss - little yellow snowballs - forming miniature ring systems around planets. You found corpses and, now and then - more often than Quaiche would have expected - they were murder victims.

It was not always easy, but Quaiche had developed a nose for the signs: he knew the right places to look. And he wasn’t finding much evidence for prior human presence around 107 Piscium.

But someone had built that bridge.

It might have been put there hundreds of years ago, he thought; some of the usual signs of human presence would have been erased by now. But
something
would have remained, unless the bridge builders had been extraordinarily careful to clean up after themselves. He had never heard of anyone doing such a thing on this scale. And why bury it so far from the usual centres of commerce? Even if people did occasionally visit the 107 Piscium system, it was definitely not on the usual trade routes. Didn’t these artists want anyone to see what they had created?

Perhaps that had always been the intention: just to leave it here, twinkling under the starlight of 107 Piscium until someone found it by accident. Perhaps even now Quaiche was an unwilling participant in a century-spanning cosmic jest.

But he didn’t think so.

What he
was
certain of was that it would have been a dreadful mistake to tell Jasmina more than he had. He had, fortunately, resisted the huge temptation to prove his worth. Now, when he did report back with something remarkable, he would appear to have behaved with the utmost restraint. No; his final message had been exquisite in its brevity. He was quite proud of himself.

The virus woke now, stirred perhaps by that fatal pride. He should have kept his emotions in check. But it was too late: it had simmered beyond the point where it would damp down naturally. However, it was too early to tell if this was going to be a major attack. Just to placate it, he mumbled a little Latin. Sometimes if he anticipated the virus’s demands the attack would be less serious.

He forced his attention back to Haldora, like a drunkard trying to maintain a clear line of thought. It was strange to be falling towards a world he had named himself.

Nomenclature was a difficult business in an interstellar culture limited by speed-of-light links. All major craft carried databases of the worlds and minor bodies orbiting different stars. In the core systems - those within a dozen or so light-years of Earth - it was easy enough to stick to the names assigned centuries earlier, during the first wave of interstellar exploration. But once you got further out into virgin territory the whole business became complicated and messy. The
Dominatrix
said the worlds around 107 Piscium had never been named, but all that meant was that there were no assigned names in the ship’s database. That database, however, might not have been seriously updated for decades; rather than relying on transmissions to and from some central authority, the anarchistic Ultras preferred direct ship-to-ship contact. When two or more of their lighthuggers met, they would compare and update their respective nomenclature tables. If the first ship had assigned names to a group of worlds and their associated geographical features, and the second ship had no current entries for those bodies, it was usual for the second ship to amend its database with the new names. They might be flagged as provisional, unless a third ship confirmed that they were still unallocated. If two ships had conflicting entries, their databases would be updated simultaneously, listing two equally likely names for each entry. If three or more ships had conflicting entries, the various entries would be compared in case two or more had precedence over a third. In that case, the deprecated entry would be erased or stored in a secondary field reserved for questionable or unofficial designations. If a system had truly been named for the first time, then the newly assigned names would gradually colonise the databases of most ships, though it might take decades for that to happen. Quaiche’s tables were only as accurate as the
Gnostic Ascension
’s; Jasmina was not a gregarious Ultra, so it was possible that this system had been named already. If that were the case, his own lovingly assigned names would be gradually weeded out of existence until they remained only as ghost entries at the lowest level of deprecation in ship databases - or were erased entirely.

But for now, and perhaps for years to come, the system was his. Haldora was the name he had given this world, and until he learned otherwise, it was as official as any other - except that, as Morwenna had pointed out, all he had really done was grab unallocated names from the nomenclature tables and flung them at anything that looked vaguely appropriate. If the system did indeed turn out to be important, did it not behove him to take a little more care over the process?

Who knew what pilgrimages might end here, if his bridge turned out to be real?

Quaiche smiled. The names were good enough for now; if he decided he wanted to change them, he still had plenty of time.

He checked his range to Hela: just over one hundred and fifty thousand kilometres. From a distance, the illuminated face of the moon had been a flat disc the colour of dirty ice, streaked here and there with pastel shades of pumice, ochre, pale blue and faint turquoise. Now that he was closer, the disc had taken on a distinct three-dimensionality, bulging out to meet him like a blind human eye.

Hela was small only by the standards of terrestrial worlds. For a moon it was respectable enough: three thousand kilometres from pole to pole, with a mean density that put it at the upper range of the moons that Quaiche had encountered. It was spherical and largely devoid of impact craters. No atmosphere to speak of, but plenty of surface topology hinting at recent geological processes. At first glance it had appeared to be tidally locked to Haldora, always presenting the same face to its mother world, but the mapping software had quickly detected a tiny residual rotation. Had it been tidally locked, the moon’s rotation period would have been exactly the same as the time it took to make one orbit: forty hours. Earth’s moon was like that, and so were many of the moons Quaiche had spent time on: if you stood at a given spot on their surface, then the larger world around which they orbited - be it Earth or a gas giant like Haldora - always hung at about the same place in the sky.

But Hela wasn’t like that. Even if you found a spot on Hela’s equator where Haldora was sitting directly overhead, swallowing twenty degrees of sky, Haldora would drift. In one forty-hour orbit it would move by nearly two degrees. In eighty standard days - just over two standard months - Haldora would be sinking below Hela’s horizon. One hundred and sixty days later it would begin to peep over the opposite horizon. After three hundred and twenty days it would be back at the beginning of the cycle, directly overhead.

The error in Hela’s rotation - the deviation away from a true tidally locked period - was only one part in two hundred. Tidal locking was an inevitable result of frictional forces between two nearby orbiting bodies, but it was a grindingly slow process. It might be that Hela was still slowing down, not yet having reached its locked configuration. Or it might be that something had jolted it in the recent past - a glancing collision from another body, perhaps. Still another possibility was that the orbit had been perturbed by a gravitational interaction with a massive third body.

All these possibilities were reasonable, given Quaiche’s ignorance of the system’s history. But at the same time the imperfection affronted him. It was as annoying as a clock that kept
almost
perfect time. It was the kind of thing he would have imagined pointing to if anyone had ever argued that the cosmos must be the result of divine conception. Would a Creator have permitted such a thing, when all it would have taken was a tiny nudge to set the world to rights?

The virus simmered, boiling higher in his blood. It didn’t like that kind of thinking.

He snapped his thoughts back to the safe subject of Hela’s topography, wondering if he might make some sense of the bridge from its context. The bridge was aligned more or less east-to-west, as defined by Hela’s rotation. It was situated very near the equator, spanning the gash that was the world’s most immediately obvious geographic feature. The gash began near the northern pole, cutting diagonally from north to south across the equator. It was at its widest and deepest near the equator, but it was still fearfully impressive many hundreds of kilometres north or south of that point.

Ginnungagap Rift, he had named it.

The rift sloped from north-east to south-west. To its west in the northern hemisphere was an upraised geologically complex region that he had named the Western Hyrrokkin Uplands. The Eastern Hyrrokkin Uplands curled around the pole to flank the rift on its other side. South of the western range, but still above the equator, was the zone that Quaiche had elected to call Glistenheath Ridge. South of the equator was another upraised area named the Gullveig Range. To the west, straddling the tropics, Quaiche identified Mount Gudbrand, the Kelda Flats, the Vigrid badlands, Mount Jord . . . to Quaiche, these names conveyed a dizzying sense of antiquity, a feeling that this world already had a richly textured past, a frontier history of epic expeditions and harrowing crossings, a history populated by the brave and the bold.

Inevitably, however, his attention returned to Ginnungagap Rift and the bridge that spanned it. The details were still unclear, but the bridge was obviously too complicated, too artful and delicate, to be just a tongue of land left behind by some erosive process. It had been built there, and it did not appear as if humans had had much to do with it.

It was not that it was beyond human ingenuity. Humans had achieved many things in the last thousand years, and throwing a bridge across a forty-kilometre-wide abyss - even a bridge as cleanly elegant as the one that spanned Ginnungagap Rift - would not be amongst the most audacious of those achievements. But just because humans
could
have done it did not mean that they
had
.

This was Hela. This was as far out in the sticks as it was possible to be. No human had any business building bridges here.

But aliens? Now that was a different matter.

It was true that in six hundred years of space travel, nothing remotely resembling an intelligent, tool-using technological culture had ever been encountered by humankind. But they had been out there once. Their ruins dotted dozens of worlds. Not just one culture either, but eight or nine of them - and that was only the tally in the little huddle of systems within a few dozen light-years of the First System. There was no guessing how many hundreds or thousands of dead cultures had left their mark across the wider galaxy. What kind of culture might have lived on Hela? Had they evolved on this icy moon, or had it just been a stopover point in some ancient, forgotten diaspora?

What were they like? Were they one of the known cultures?

He was getting ahead of himself. These were questions for later, when he had surveyed the bridge and determined its composition and age. Closer in, he might well find other things that the sensors were missing at this range. There might be artefacts that unequivocally linked the Hela culture to one that had already been studied elsewhere. Or the artefacts might cinch the case the other way: an utterly new culture, never encountered before.
