The hardfield generators rested in transporters heavily constructed of carbide steel laminated with bearing materials and shock-absorbing foamed resins. Designed to bend and twist under huge loads, then return to their original shape, they were low and incredibly heavy, and in this situation not worth the energy expenditure of AG, so they ran on two sets of caterpillar tracks. Two thousand of them guarded the landward perimeter, their anchor spikes driven down through ten yards of earth until they encountered bedrock. The generators themselves were spherical, covered in flexible cooling pipes and bristling with radiator fins. The fields they projected, as well as being impervious to matter, were polarized against radiations outside the human visual spectrum. Those fields also slanted at forty-five degrees, to deflect the Shockwave rather than stop it completely. The tank commander told her it still seemed likely that any generators surviving the blast would be driven, along with their transporters, deep into the ground.

‘Why not wait until everyone is completely clear?’ she asked, once again perching on his tank.

The man himself stood nearby, smoking a cigarette. He told her it was a habit acquired after spending too much time in his youth taking part in VR interactives based on celluloid films that were centuries old. He found it relaxed him.

‘Coloron keeps destroying Jain tech on the surface, but it continues burrowing into the ground. It may be doing so slowly at present, but that’s only because the arcology was necessarily built on solid granite. Once it reaches the softer strata, it’ll speed up. So if we don’t take it out before then, we may lose the planet.’

The arcology was now a silvery line on the horizon from which fires sprouted. Poised like stormclouds over it, atmosphere ships, having hurled down their lightnings, now departed to make way for what was to come. The tank commander tossed her a set of goggles.

‘I thought the hardfields will block the flash?’ she said.

‘They will, but there’s no guarantee they’ll be there all the time.’

Aphran grunted her thanks and pocketed the goggles.
