Iain Banks - The Algebraist

So quite why the Dwellers would ever have bothered building a secret wormhole network was something of a mystery, as was how they had managed to keep it secret all these hundreds of millions of years, not to mention how this fitted in with the rather obvious nature of each different Dweller community’s isolation from each other.

Nevertheless, the myth of the Dweller List continued to excite people in general and conspiracy theorists in particular, especially in times of threat and desperation, when it would be really, really great if a secret wormhole network did exist.

Fassin agreed with the textbooks that it had been no coincidence the List had first turned up during the Burster War, when the whole galactic community had seemed to be falling apart, and people were looking for salvation, for hope, anywhere. Then, the arteria total had been falling from its earlier — and then all-time — high of nearly 39,000 to under a thousand. At the nadir of the Third Chaos there had been less than a hundred “holes in the whole galaxy, and the Dwellers hadn’t stepped in then with an offer to let everybody else use this secret system. If not then, when the light of civilisation seemed to be fading from the great lens entirely, then when? When and why would they ever come galloping to the rescue?

Part of the seductive attraction of the List was its sheer size. It contained over two million sets of alleged portal coordinates, implying more than one million arteria, presumably linked in a single enormous network. At the height of the Third Complex, eight thousand years earlier, there had been exactly 217,390 established wormholes threading the galaxy together, and that was as good, as far as was known, as it had ever got. If the Dweller List genuinely enumerated existing portals and arteria, it would represent the promise of instigating the single greatest change in the history of the galaxy; the sudden linking-up of two million systems, many of which had never had any connection before, the bringing together of almost everybody everywhere — the very furthest, most utterly isolated star would likely be a mere decade or two away from the nearest portal — and the near-instant revitalising, on a scale unheard of in nearly twelve billion years of tenacious, sporadically stuttering civilisation, of the entire galactic community.

It was, Fassin and almost all his fellow Seers had long thought, a forlorn hope. The Dwellers didn’t need or show any sign of using wormholes. Being Dwellers, they naturally claimed they were experts at arteria and portal technology, and certainly they were not afraid of using wormholes, it was just that they didn’t see the need for them… but if they ever had been seriously involved with wormhole production, those days were long gone. In any case, the List itself, which had been lying around in libraries and data reservoirs, multitudinously copied for hundreds of millions of years, accessible to anybody with a link, was not the end of the story; it just gave the rough coordinates of two million gas-giants in two million systems. What was needed was a more precise location.

The obvious places to look were the relevant Trojan or Lagrange points, the gravitationally stable locations dotted around and between the orbits of the various planets in the named systems. However, these had all long since been eliminated. After that it got much more tricky. In theory a worm-hole mouth could be left in any stable orbit anywhere in a system and never be found unless you practically tripped over it. Working portals were anything up to a kilometre wide and had an effective mass of several hundred thousand tonnes, whereas a portal shrunk and stabilised and set up to keep itself that way with relatively simple automatics systems could lie in an orbit as far out as a system’s Oort cloud with a gravitational footprint of less than a kilogramme more or less indefinitely. The problem was how to describe where it was.

Allegedly there was some extra set of coordinates, or even a single mathematical operation, a transform, which, when applied to any given set of coordinates in the original list, somehow magically derived the exact position of that system’s portal. The obvious objection to this was that after four hundred million years, minimum, there was no known coordinate system ever devised capable of reliably determining where something as small as a portal was. (Unless the holes had all somehow automatically kept themselves in the same relative position all that time. Given the haphazard and cavalier attitude that Dwellers tended to display towards anything especially high-tech, this was regarded as highly unlikely.)

“So,” the image hovering above the dark device in the centre of the audience chamber said, “if I may assume we are all happy we know what we’re talking about…’ It looked around them again. Nobody demurred.

“The Dweller List,” the hologram said, “supposedly giving the approximate location of two million ancient portals dating from the time of the Third Diasporian Age, has been dismissed as an irrelevance, a lie or a myth for over a quarter of a billion years. The so-called Transform, supposed to complete the information required to access this secret network, has proved as elusive as it is unlikely to work if it does exist. Nevertheless. Some new information has come to light, thanks to Seer, now Major, Taak.” Fassin was aware that he was being looked at again. He just kept staring at the hologram.

“A little under four hundred years ago,” the hologram said, “Seer Taak took part in an extended expedition — a ‘delve’ as it is known — which took him amongst the Dwellers of Nasqueron, and specifically into the company of a group of Dweller youngsters called the Dimajrian Tribe. While with them, he encountered an antique Dweller who — in a fit of generosity unusual in his kind — granted Seer Taak access to a small library of information, part of a still larger hoard.”

(This was the wrong way round — the myth, not the fact. Fassin had been with Valseir for centuries and the Dimajrian Tribe for less than a year. He hoped that the rest of the Admiral’s information was more reliable. All the same, he had a sudden, vivid memory of choal Valseir, huge and ancient, accoutred with rags, draped in life-charms, floating absently within his vast nest-bowl of a study, deep in the lost section of abandoned CloudTunnel on the rim of a giant, dying storm which had long since broken up and dissipated. “Clouds. You are like clouds,” Valseir had told Fassin. At the time he hadn’t understood what the ancient Dweller had meant.)

“The raw data containing this information was passed on to the Shrievalty for analysis,” the image hovering above the black device said. “Twenty years later, after the usual analysis and interpretation and, you’d imagine, with plenty of time for second thoughts, re-evaluations and sudden inspirations, it was shared with the Jeltick under the terms of an infotrade agreement.”

The Jeltick were an arachnoid species, eight-limbed — 8ar, in the conventional shorthand of the galactic community. Obsessive cataloguers, they were one of the galaxy’s two most convincing self-appointed historian species. Timid, cautious, deliberate and very inquisitive (at a safe remove), they had been around for much longer than Quick species usually lasted.

“Somehow, the Jeltick contrived to notice something the Shrievalty had missed,” the hologram continued. (Now, Fassin noticed, it was Colonel Somjomion’s turn to look awkward and aggrieved.) “Heads have rolled due to this incompetence,” the image told them. It smiled. “Ido not speak figuratively”

Colonel Somjomion compressed her lips and rechecked something on the machine she was in charge of.

“Within months,” the hologram said, “the Jeltick sent their best excuse for a battle fleet to the Zateki system — unexplored for millennia — which lies about eighteen years from the portal at Rijom; they got there in twenty years, so they were not exactly dawdling. It ought to be pointed out that the Jeltick would never normally try anything so dynamic, or risky.
