The AI checked all the systems of the toroidal satellite, finding it was up to power, with plenty of fuel available for the fusion reactor of which most of the satellite consisted. Even at that moment, a tanker craft was approaching from a recently arrived cargo carrier. One of its three tanks contained hugely compressed deuterium in the metallic state—further fuel for the reactor—the other two were filled with cupronickel dust to provide the particulate matter for the cannon itself.
I am procrastinating.
That system check had been an unnecessary delay.
‘Firing particle cannon,’ Coloron announced.
The turquoise beam stabbed down through atmosphere and struck the already fire-blackened chunk of arcology just off centre. The beam cut through its various levels like a thermic lance through a beehive. Fire and smoke fountained half a mile into the sky. The cannon satellite, adjusted by the gravplate ring on the fusion-reactor torus, incrementally tilted and began to revolve. Down below, the beam began to cut spirally outwards from its initial strike point. Viewing the scene in infrared, Coloron estimated the extent of the firestorm now exploding through the levels below. Within minutes the beam reduced the originally excised piece of arcology to glowing slag at the bottom of a huge pit. Shutting off the cannon the AI then contemplated what it had done. It had just obliterated about ten cubic miles of arcology and killed thousands of inhabitants, and that seemed likely to be only the beginning. Now checking the map relayed by the HK program, Coloron saw energy flowing away from that same area, and Jain tech material resources being transferred. The substructure, Coloron realized, could be herded.
‘I suggest you cut a line down to bedrock,’ sent Brutus the AI controlling the dreadnought above, which, unusually, bore a different name: the Brutal Blade.
‘That is my intention,’ Coloron replied. ‘With what happens next, such a division will certainly be required.’ The AI viewed the dreadnought through various sateyes arrayed above the particle cannon. It was a utile vessel looking nothing like a blade. Two miles across at its widest point, it bore some resemblance to a gigantic lump of metallized liver, with many organic tubes opening to space—heavy armour gave it its shape and those tubes were its weapons systems. ‘CTD imploder, lowest yield, take out this fusion reactor,’ Coloron ordered, sending the location of the mentioned reactor.
One of the tubes, a linear accelerator, spat out a black sphere that hurtled down into atmosphere, glowed red, then white, and began to ablate. Ten miles up it shed two burning hemispheres. The missile it contained slammed down through a wheat field, igniting a small fire around the surface puncture. A microsecond later, the field bulged up into a hill; it started smoking, then abruptly combusted. Flame jetted from arcology vents within a mile of this, then smoke from those lying beyond them. Crowds of people still moving away along the north-west shore gazed back at debris blasted from the numerous exits in the arcology’s edge. Coloron measured the spread of heat, observed the substructure’s reaction to this latest strike, then sent a map selecting the positions of other reactors, and locations of those enemy materials and energy stores.
‘Interesting,’ commented Brutus.
‘After I have cut the division,’ the Coloron instructed, ‘you must take out all those targets at once.’ The AI knew that, on some level of awareness, the Jain substructure would realize the disposition of its forces had been discovered. It would probably find the HK, but by then the damage would be done.
Incrementally again, the particle cannon tilted. The turquoise beam hit the sea this time, evaporating billions of cubic yards of brine. It sliced into the arcology wall then began to burn across. From orbit a cloud mass could be seen forming in its trail. While still metaphorically holding a finger on the firing button, Coloron noted monitors and Rescue staff loading into AG ambulances those injured by the departure of the crowds at Runcible 5. On the map updated by the HK program, the AI saw that the Jain substructure now lay only a mile away from there. The immediate blast radius around 6 was clear of people, though there were still some stragglers within areas likely to be devastated by the Shockwave. The Jain tech lay a mile and a half away from Runcible 6. Coloron waited.
Half an hour passed, then an access panel for an optical junction sprang away from the wall on the furthest edge of one of Runcible 5’s lounges. Something like a long-fingered stainless steel hand groped out, and began to extend its fingers down the wall. On another wall steel buds grew through sheet bubble metal and squeezed out grey tendrils. The last three ambulances departed, whereupon some other ambulances tried returning, because there were still people alive in here. Too late, because Coloron began closing blast doors behind the departing ambulances. Now humanoid figures began appearing, their clothing burnt and hanging in tatters, their bodies blackened, and pinkish slithing movement visible through their wounds. The AI began shutting down systems as soon as it felt informational intrusion—as it had been doing all along throughout the advance of this feral technology. Soon its total perception of the area became limited to a few scattered cameras. Then came the expected intrusion into the systems of the runcible itself.
The runcible buffers held a huge charge, permanently topped up by the fusion reactor located on the floor below the runcible itself. With safety circuits offline, Coloron released this entire charge into the runcible. A warp generated, tuned out of U-space, tried to create space of its own, bounced out into realspace, then collapsed. It sucked in the horns of the runcible, the dais, the fusion reactor, several bodies—some still alive—and much of the surrounding complex, crunching everything down into a spherical superdense mass. At the centre of this mass: fusion.
From the cannon satellite Coloron observed the subsequent explosion flinging millions of tons of debris into the air. A briefly stabilized fusion reaction dropped a yard-wide white sun straight down to the bedrock. As the smoke cleared, the AI observed a glowing two mile-wide crater cut into the top half of the arcology. Eight minutes later a similar crater appeared in place of Runcible 6.Twenty minutes after that, the particle beam cut its way out from the north wall of the arcology.
‘Now,’ Coloron sent to Brutus.
Missile after missile departed the Brutal Blade; a vicious insect swarm hurtling down towards the planet. Coloron almost flinched. The harsh reality of its mind did not permit ignorance of how many had died during the last hour, and of how many were about to die. Yes, Jain technology controlled most of them, but they were people nevertheless. No fewer than 110,000 of them. And even then the advance would continue, for the AI only slowed it down, inconvenienced it.
The planetary system consisted of an immense green gas giant the size of Jupiter, but half as far again from the sun as that Jovian. Further from the sun than it lay a ring of icy planetoids and asteroidal debris, while around it orbited more still. Within its orbit were four planets: one icy world three times the size of Earth and bearing its own ring system, one orbiting close around the sun, and two that lay within the sun’s green belt. The inner of the two green-belt planets was a hot world similar to the one where Erebus had destroyed its rebel faction. King dropped telefactors to study this living planet, for it seemed perfect for a base, yet already King guessed this place to be empty of intelligent life.
