is coming fast. And Carlotta thinks of what she saw when she raided Dan-Oâs ditty bag, the blue metal barrel with a black gnurled grip, a thing she had stared at, hefted, but ultimately disdained.
Â
We dropped back down the curve of that elliptic, girl, and suddenly the Fleet began to vanish like drops of water on a hot griddle. Erasmus saw it first, because of what he was, and he set up a display so I could see it too: Fleet-swarms set as ghostly dots against a schema of the galaxy, the ghost-dots dimming perilously and some of them blinking out altogether. It was a graph of a massacre. âCanât anyone stop it?â I asked.
âThey would if they could,â he said, putting an arm (now that he had grown a pair of arms) around me. âThey will if they can, Carlotta.â
âCan we help?â
âWe are helping, in a way. Existing the way we do means they donât have to use much mentation to sustain us. To the Fleet, weâre code that runs a calculation for a few seconds out of every year. Not a heavy burden to carry.â
Which was important, because the Fleet could only sustain so much computation, the upper limit being set by the finite number of linked nodes. And that number was diminishing as Fleet vessels were devoured wholesale.
âLast I checked,â Erasmus said (which would have been about a thousand years ago, realtime), âthe Fleet theorized that the Enemy is made of dark matter.â (Strange stuff that hovers around galaxies, invisiblyâit doesnât matter, girl, take my word for it; youâll understand it one day.) âTheyâre not material objects so much as processes âparasitical protocols played out in dark matter clouds. Apparently, they can manipulate quantum events we donât even see.â
âSo we canât defend ourselves against them?â
âNot yet. No. And you and I might have more company soon, Carlotta. As long-timers, I mean.â
That was because the Fleet continued to rapture up dying civilizations, nearly more than their shrinking numbers could contain. One solution was to shunt survivors into the Long Now along with us, in order to free up computation for battlefield maneuvers and such.
âCould get crowded,â he warned.
âIf a lot of strangers need to go Longâ¦â I saidâ¦
He gave me a carefully neutral look. âFinish the thought.â
âWellâ¦canât we justâ¦go Longer?â
Â
Fire a pistol in a tin box like this ratty trailer and the sound is ridiculously loud. Like being spanked on the ear with a two-by-four. Itâs the pistol shot that finally wakes the young Carlotta. Her eyelids fly open like window shades on a haunted house.
This isnât how the elder Carlotta remembers it. Gunshot? No, there was no gunshot ; she just came awake and saw the ghostâ
And no ghost, either. Carlotta tries desperately to speak to her younger self, wills herself to succeed, and fails yet again. So who fired that shot, and where did the bullet go, and why canât she remember any of this?
The shouting in the next room has yielded up a silence. The silence becomes an eternity. Then Carlotta hears the sound of footstepsâshe canât tell whoseâapproaching her bedroom door.
Â
In the end, almost every conscious function of the Fleet went Long, just to survive the attrition of the war with the dark-matter beings. The next loop through the galactic core pared us down to a fraction of what we used to be. When I got raptured up, the Fleet was a distributed cloud of baseball-sized objects running quantum computations on the state of their own dense constituent atomsâ millions and millions of such objects, all linked together in a nested hierarchy. By the time we orbited back up our ellipsis, you could have counted us in the thousands, and our remaining links were carefully narrowbanded to give us maximum stealth.
So us wild timesliders
