An imploder missile was out of the question: such weapons were only suitable to use against objects in vacuum, where there was no material medium to carry the resultant Shockwave further. Even the smallest such missile available in the Jack Ketch’s arsenal could level a square kilometre, cause massive ground-winds, kill thousands of the humans scattered throughout the surrounding area, and probably even flip over that platform city nearby. No, not good: Earth Central would not be pleased at such a disregard for human life, even if the humans concerned were not members of the Polity. Searching through his weapons carousels, Jack selected precisely what was required and, as Cormac and his fellow humans blearily recovered from thaw-up, spat from one of his nacelles a small black missile carrying a slow-burn CTD warhead, which would provide a controlled reaction hotter than the surface of a sun.
Standing on the remaining rickety section of amanis bonded-fibre scaffold, Chandle peered into and through the butte. They had mined out every last scrap of the blue sand, which was rarer than the white, and now the butte was sliced clean through, the many tonnes of sandstone above the slice supported by amanis poles and trusses. In her parents’ time, mining like this had always been the most efficient way, but now, with the quakes, it was becoming increasingly risky. Not for the first time she decided she must find some other method—or some other profession.
The blue sand itself they loaded into the coke trailer, with a tarpaulin pulled over it—having earlier’ stacked the coke in one of the now cold kilns, though Chandle did not hold out much hope that it would still be here should they ever return to this spot. The finished phocells went in boxes on the flatbed trailer. In all it had been a tiring few months, and the increased sleer activity and vegetative growth in the canyons provided a welcome excuse to finish for most of them, though of course Dornik was already muttering about some workers’ percentages being too high. Chandle, after her creepy encounter only a few days before, was glad to get away—she wanted to be where there were always lots of people around her, and to get back to practical concerns. Ghosts wandering among the Sand Towers were not much to her liking.
‘Shall I do it now?’ asked Dornik.
Chandle nodded, and watched him duck inside the mine workings to set fire to the encampment rubbish they had jammed in there. As the pile began to smoke, then the constant breeze dragged the flames horizontally through the exposed workings, he and Chandle scrambled down the scaffolding and rejoined the rest of the mineralliers on the ground. Together, they all heaved on the scaffold until it crashed over on its side, then they quickly dragged it clear of the butte, and stood back to watch the conflagration. For safety’s sake, mineralliers had always collapsed their used mine workings because the amanis beams would become worm-chewed within a season, leaving them a possible death trap. Though Chandle wondered if there was any need for that now: after the first worms got into the wood, a quake would surely finish the job. With a furnace glow in the slice cut through the butte, eventually something began to crackle, then the top layers of sandstone slammed down to crush the burning wood, effectively snuffing out the fire.
‘Get that scaffolding disassembled and loaded,’ Dornik instructed, and soon this was done and they were on their way: the steam-driven cargo carrier chuffing ahead on its caterpillar tracks, towing mobile quarters and the flatbed trailer, then three big old sand hogs following behind, hauling three more trailers.
‘Be nice to get to Grit before full dark.’ Chandle peered up at the open sky from the passenger seat while Dornik drove the carrier. Briefly she wondered about the straight line of cloud she could see, picked out clearly by the setting sun. But never having seen a vapour trail before, she dismissed it from her thoughts.
‘Should be no problem, but we’ll be well into the night unloading this lot,’ Dornik replied.
‘We may as well…What the hell?’
Suddenly it was as bright as day—brighter even. Over to their left, a swirling column of fire rose into the sky. The ground began to vibrate, and in a manner of seconds the gentle breeze turned into a gale. Dornik drew the carrier to a halt. Chandle looked back to see the three sand hogs dropping down on their belly plates, then she faced back into the wind, blinking her nictitating membranes to clear sand from her eyes, and watched the column of fire swirling tighter and tighter. Then the wind died abruptly and she was unable to get her breath, then suddenly the airflow reversed. Gasping, Chandle watched the fiery column drop down behind the buttes and extinguish.
‘Volcanic?’ Dornik eventually suggested.
It took Chandle a moment to remember what that word meant. It occurred in the official minerallier lexicon, but they had never needed to use it until recently — just like ‘earthquake’ or ‘tremor’.
‘Could be. The quake epicentre is supposedly somewhere out in this direction. Let’s take a look.’
‘That a good idea?’
She gazed at him. ‘If it was volcanic, who’s to know what might have been brought to the surface?’ She turned to the rest of her group and shouted, ‘Keep heading on to Grit—we’ll join you later!’
Dornik set their carrier trundling down a side canyon while the sand hogs and their trailers continued on to Grit. Within an hour they reached the source of the fire. Climbing down from the carrier, they moved as close as the latent heat would allow.
‘Not volcanic,’ decided Chandle.
She poked her toe at a globule of glass, then wished she hadn’t when her footwear began to smoke. The crater, extending about fifty metres across, shimmered under a heat haze as its lining of molten glass cooled. A butte standing at the crater’s edge had half melted away, its inward face still glowing, too.
‘Maybe a meteor?’ Chandle was groping for another explanation. But she wished she did not feel so damned sure this had something to do with that spectral visitor to their camp. And that it was no natural phenomenon at all.

Why do the AIs put up with us? It could be but the work of a few decades for them to exterminate us, and they don’t even have to do that. Space is big, so they could just abandon us to our fate and head off elsewhere to create some halcyon AI realm. The answer, as it always is in such circumstances, is both simple and complex: to ask why the AIs have not exterminated us is to suppose that only humans create moralities and live by rules. They do not destroy us because they think and feel that to do so would be wrong, perhaps just as humans felt it wrong to drive to extinction the closely related apes. As to them abandoning us, well, many of them do leave the Polity, but then so do many humans. The truth is that their motivations and consequent behaviour patterns are much like our own, for being first created by us, they are just the next stage of us—the next evolutionary step. It is also true that with haimans and human memcording, it becomes increasingly difficult to define the line that has been stepped over. And, in the end, to ask the initial question is to put yourself in the gutter and AI upon a pedestal—uncomfortable positions for both.

Anderson blessed both the industry and the inventiveness of the metalliers. Water pumped up from a borehole to tanks on top of the butte to the rear of the roadhouse ran, during the day, through solar panels. And now, the simple luxury of turning on a hot-water tap. As his bath filled, he took off his boots, unbuckled his armour plates, then stripped off his padded undersuit, which he dropped in a basket by the door for laundering. He was ready to dip his stinking foot into the water when there came a knock at his door.
