A Fire Upon the Deep

by Vernor Vinge

  Note 975

  The crew of the Out of Band II brought weapons into a habitat, kill several local sophonts, and escaped before our musicians [harmonizers? police?] were properly notified. We have good reason to wish them ill.

  Yet our misfortune is a small thing compared to the unmasking of this secret mission. We are very grateful that the Alliance is willing to risk so much in following this lead.

  Note 976

  There’s more than the usual number of unsubstantiated assertions floating around on this news thread. We hope our facts will wake some people up. In particular, consider what “Hanse” may really be. The Perversion is very visible in the High Beyond, where it has great power and can speak with its own voice. Down here, it is more likely that deception and covert propaganda will be its tools. Think on this when you read postings from unidentified entities such as “Hanse”!

  Note 977

  Ravna gritted her teeth. The hell of it was, the facts in the posting were correct. It was the inferences that were vicious and false. And she couldn’t guess if this were some shade of black propaganda or simply Saint Rihndell expressing honest conclusions (though Rihndell had never seemed so trusting of the butterflies).

  Note 978

  One thing all the News seemed to agree on: Much more than the Alliance fleet was chasing the OOB. The swarm of ultradrive traces could be seen by anyone within a thousand light-years. The best guess was that three fleets pursued the OOB. Three! The Alliance for the Defense, still loud and boastful, even though suspected (by some) of being opportunistic genocides. Behind them, Sjandra Kei … and what was left of Ravna’s motherland; in all the universe perhaps the only folk she could trust. And just behind them, the silent fleet. Diverse news posters claimed it was from the High Beyond. That fleet might have problems at the Bottom, but for now it was gaining. Few doubted that it was the Perversion’s child. More than anything, it convinced the universe that the OOB or its destination was cosmically important. Just why it was important was the big question. Speculation was drifting in at the rate of five thousand messages per hour. A million different viewpoints were considering the mystery. Some of those viewpoints were so alien that they made Skroderiders and Humans look like the same species. At least five participants on this News thread were gaseous inhabitants of stellar coronas. There were one or two others that Ravna suspected were uncataloged races, beings so shy that this might be their first active use of the Net ever.

  Note 979

  The OOB‘s computer was a lot dumber than it had been in the Middle Beyond. She couldn’t ask it to sift through the messages looking for nuance and insight. In fact, if an incoming message didn’t have a Triskweline text, it was often unreadable. The ship’s translator programs still worked fairly well with the major trade languages, but even there the translation was slow and full of alternative meanings and jabberwocky. It was just another sign that they were approaching the Bottom of the Beyond. Effective translation of natural languages comes awfully close to requiring a sentient translator program.

  Nevertheless, with proper design, things might have been better. The automation might have degraded gracefully under the restrictions imposed by their depth. Instead, gear just stopped working; what remained was slow and error-prone. If only the refitting had been completed before the Fall of Relay. And just how many times have I wished for that? She hoped things were as bad aboard the pursuing ships.

  So Ravna used the ship to do light culling on the Threats newsgroup. Much of what was left was inane, as from people who see “portents in the weather” —

  Apologies first if I am repeating obvious conclusions. My only gateway onto the Net is very expensive, and I miss many important postings. I think that anyone following both Great Secrets of Creation and Threat of the Blight would see an important pattern. Since the events reported by Harmonious Repose information service, most agree that something important to the Perversion exists at the Bottom of the Beyond in region […]. I see a possible connection here with the Great Secrets. During the last two hundred and twenty days, there have been increasing reports of zone interface instability in the region below Harmonious Repose. As the Blight threat has grown and its attacks against advanced races and other Powers continued, this instability has increased. Could there not be some connection? I urge all to consult their information on the Great Secrets (or the nearest archive maintained by that group). Events such as this prove once again that the universe is all ronzelle between.

Cricketsong has been on the Net for more than ten thousand years. Apparently it is a fanatical studier of paths to Transcendence. For eight thousand years it has been the heaviest poster on “Where are they now” and related groups. There is no evidence that any Cricketsong settlement has itself Transcended. Cricketsong is sufficiently peculiar that there is a large news group for speculation concerning the race itself. Consensus is that Cricketsong was designed by High Willow as a probe back into the Beyond, that the race is somehow incapable of attempting its own Transcendence.]

  Text of message:

  Note 988

  Contrary to other postings, there are a number of reasons why a Power might install artifacts at the Bottom of the Beyond. The Abselor’s message on this thread cites some: some Powers have documented curiosity about the Slow Zone and, even more, about the Unthinking Depths. In rare cases, expeditions have been dispatched (though any return from the Depths would occur long after the dispatching Power lost interest in all local questions).

  However, none of these motives are likely here. To those who are familiar with Fast Burn transcendence, it is clear that the Blight is a creature seeking stasis. Its interest in the Bottom is very sudden, provoked, we think, by the revelations at Harmonious Repose. There is something at the Bottom that is critical to the Perversion’s welfare.

  Consider the notion of ablative dissonance (see the Where Are They Now group archive): No one knows what set-up procedures the humans of Straumli Realm were using. The Fast Burn may itself have had Transcendent intelligence. What if it became dissatisfied with the direction of the channedring? In that case it might try to hide the jumpoff birthinghel. The Bottom would not be a place where the algorithm itself could normally execute, but avatars might still be created from it and briefly run.

  Note 989

  Up to a point, Ravna could almost make sense of
it; ablative dissonance was a commonplace of Applied Theology. But then, like one of those dreams where the secret of life is about to be revealed, the posting just drifted into nonsense.

  There were postings that were neither asinine nor obscure. As usual, Sandor at the Zoo had a lot of things dead right:

  In case you don’t know, Sandor Intelligence has a number of different Net feeds. We can collect messages on paths that have no intermediate nodes in common. Thus we can be fairly confident that news we receive has not been tampered with en route. (There remain the lies and misunderstandings that were present to begin with, but that’s something that makes the intelligence business interesting.)

  The Blight has been our top priority since its instantiation a year ago. This is not just because of the Blight’s obvious strength, the destruction and the deicides it has committed. We fear that all this is the lesser part of the Threat. There have been perversions almost as powerful in the recorded past. What truly distinguishes this one is its stability. We see no evidence of internal evolution; in some ways it is less than a Power. It may never lose interest in controlling the High Beyond. We may be witnessing a massive and permanent change in the nature of things. Imagine: a stable necrosis, where the only sentience in the High Beyond is the Blight.

  Thus, studying the Blight has been a matter of life and death for us (even though we are powerful and widely distributed). We’ve reached a number of conclusions. Some of these may be obvious to you, others may sound like flagrant speculation. All take on a new coloring with the events reported from Harmonious Repose:

  Almost from the beginning, the Blight has been searching for something. This search has extended far beyond its aggressive physical expansion. Its automatic agents have tried to penetrate virtually every node in the Top of the Beyond; the High Network is in shambles, reduced to protocols scarcely more efficient than those known below. At the same time, the Blight has physically stolen several archives. We have evidence of very large fleets searching for off-Net archives at the Top and in the Low Transcend. At least three Powers have been murdered in this rampage.

  And now, suddenly, this assault has ended. The Blight’s physical expansion continues, with no end in sight, but it no longer searches the High Beyond. As near as we can tell, the change occurred about two thousand seconds before the escape of the human vessel from Harmonious Repose. Less than six hours later, we saw the beginnings of the silent fleet that so many are now speculating about. That fleet is indeed the creature of the Blight.

  In other times, the destruction of Sjandra Kei and the motives of the Alliance for the Defense would all be important issues (and our organization might have interest in doing business with those affected). But all that is dwarfed by the fact of this fleet and the ship it pursues. And we disagree with the analysis [implication?] from Harmonious Repose: it is obvious to us that the Blight did not know of the Out of Band II until its discovery at Harmonious Repose.

  That ship is not a tool of the Blight, but it contains or is bound for something of enormous importance to the Blight. And what might that be? Here we begin frank speculation. And since we are speculating, we’ll use those powerful pseudo-laws, the Principles of Mediocrity and Minimal Assumption. If the Blight has the potential for taking over all the Top in a permanent stability, then why has this not happened before? Our guess is that the Blight has been instantiated before (with such dire consequence that the event marks the beginning of recorded time), but it has its own peculiar natural enemy.

  The order of events even suggests a particular scenario, one familiar from network security. Once upon a time (very long ago), there was another instance of the Blight. A successful defense was mounted, and all known copies of the Blight’s recipe were destroyed. Of course, on a wide net, one can never be sure that all copies of a badness are gone. No doubt, the defense was distributed in enormous numbers. But even if a harboring archive were reached by such a distribution, there might be no effect if the Blight were not currently active there.

  The luckless humans of Straumli Realm chanced on such an archive, no doubt a ruin long off the Net. They instantiated the Blight and incidentally — perhaps a little later — the defense program. Somehow that Blight’s enemy escaped destruction. And the Blight has been searching for it ever since —in all the wrong places. In its weakness, the new instance of the defense retreated to depths no Power would think of penetrating, whence it could never return without outside help. Speculation on top of speculation: we can’t guess the nature of this defense, except that its retreat is a discouraging sign. And now even that sacrifice has gone for naught, since the Blight has seen through the deception.

  The Blight’s fleet is clearly an ad hoc thing, hastily thrown together from forces that happened to be closest to the discovery. Without such haste, the quarry might have been lost to it. Thus the chase equipment is probably ill-suited to the depths, and its performance will degrade as the descent progresses. However, we estimate that it will remain stronger than any force that can reach the scene in the near future.

  We may learn more after the Blight reaches the Out of Band II‘s destination. If it destroys that destination immediately, we’ll know that something truly dangerous to the Blight existed there (and may exist elsewhere, at least in recipe form). If it does not, then perhaps the Blight was looking for something that will make it even more dangerous than before.

  Note 994

  Ravna sat back, stared at the display for some time. Sandor Arbitration Intelligence was one of the sharpest posters in this newsgroup…. But now even their predictions were just different flavors of doom. And all so damn cool they were, so analytical. She knew that Sandor was polyspecific, with branch offices scattered through the High Beyond. But they were no Power. If the Perversion could knock over Relay and kill Old One, then all of Sandor’s resources wouldn’t help it if the enemy decided to gobble them up. Their analysis had the tone of the pilot of a crashing ship, intent on understanding the danger, not taking time out for terror.

  Note 995

  Oh Pham, how I wish I could talk to you like before! She curled gently in on herself, the way you can in zero gee. The sobs came softly, but without hope. They had not exchanged a hundred words in the last five days. They lived as if with guns at each others’ heads. And that was the literal truth —she had made it so. When she and he and the Skroderiders had been together, at least the danger had been a shared burden. Now they were split apart and their enemies were slowly gaining on them. What good could Pham’s godshatter be against a thousand enemy ships and the Blight behind them?

  Note 996

  She floated for a timeless while, the sobs fading into despairing silence. And again she wondered if what she’d done could possibly be right. She had threatened Pham’s life to protect Blueshell and Greenstalk and their kind. In doing so, she had kept secret what might be the greatest treachery in the history of the Known Net. Can one person make such a decision? Pham had asked her that, and she had answered yes but….

  The question toyed with her every day. And every day she tried to see some way out. She wiped her face silently. She didn’t doubt what Pham had discovered.

  Note 997

  There were some smug posters on the Net wh
o argued that something as vast as the Blight was simply a tragic disaster, and not an evil. Evil, they argued, could only have meaning on smaller scales, in the hurt that one sophont does to another. Before RIP, the argument had seemed a frivolous playing with words. Now she saw that it was meaningful — and dead wrong. The Blight had created the Riders, a marvelous and peaceful race. Their presence on a billion worlds had been a good. And behind it all was the potential for converting the sovereign minds of friends into monsters. When she thought of Blueshell and Greenstalk, and the fear welled up and she knew the poison that was there —even though they were good people— then she knew she’d glimpsed evil on the Transcendent scale.

  She had gotten Blueshell and Greenstalk into this mission; they had not asked for it. They were friends and allies, and she would not harm them because of what they could become.

  Note 998

  Maybe it was the latest news items. Maybe it was confronting the same impossibilities for the n’th time: Ravna gradually straightened, looking at those last messages. So. She believed Pham about the Skroderider threat. She also believed these two were only enemies in potential. She had thrown away everything to save them and their kind. Maybe it was a mistake, but take what advantage there is in it. If they are to be saved because you think they are allies, then treat them as allies. Treat them as the friends they are. We are all pawns together.

  Ravna pushed gently toward her cabin’s doorway.

  Note 999

  The Skroderiders’ cabin was just behind the command deck. Since the debacle at RIP, the two had not left it. As she drifted down the passage toward their door, Ravna half-expected to see Pham’s handiwork lurking in the shadows. She knew he was doing his best to “protect himself”. Yet there was nothing unusual. What will he think of my visiting them?

  She announced herself. After a moment Blueshell appeared. His skrode was wiped clean of cosmetic stripes, and the room behind him was a jumble. He waved her in with quick jerks of his fronds.
