A line of AG tanks curved from horizon to horizon. Behind it, and above, massed other Polity forces: mobile quadruped rail-guns stamping about impatiently on steel legs, the ends of their huge cylindrical magazines, attached either side of their main bodies, looking like blank eyes; troop transports and swarms of armoured troops, some hovering in AG harnesses, some on platforms mounting particle cannons; atmosphere jets speeding in squadrons overhead, avoiding two massive atmosphere gunships hanging in the sky like city blocks turned sideways; a multitude of drones of all kinds swarming all about like steel insects. This then was the might of the Polity mobilized for ground warfare. Cormac considered it an impressive and sobering sight, but knew the forces assembled here to be only a fraction of a per cent of the whole.

Breaks through the ground line were fenced on either side, the intervening channels leading back to where ECS Rescue and Medical personnel awaited. More of these were arriving from the initial landings beside the arcology. The air ambulances and ships these personnel occupied were also obliged to pass underneath the scanning drones, no exceptions.

‘Would you like to be down there?’ Cormac asked.

Arach, who had been peering for some time over the side of the stripped-down gravcar Cormac guided, turned his nightmare head, opened and closed his pincers, his two large red eyes and other smaller ones gleaming. ‘I would rather be over there.’ Arach gestured with one sharp leg towards the arcology itself. Seemingly on cue, a bright flash from that direction cast long shadows behind the ground forces. Shortly after came a thunderous rumble. Through his gridlink Cormac picked up the news.

‘Another runcible,’ he declared.

Arach grunted, then with a clattering moved up beside Cormac to peer ahead at the arcology. Turquoise fire now stabbed down, again and again, and the thunder became constant. Smoke, fire and debris, carried up in mini tornadoes, became visible.

‘And that?’ asked the drone.

‘Coloron is destroying the coastal edge of the arcology to prevent the Jain tech spreading into the sea,’ he replied. ‘The AI has burnt down to the bedrock for about a mile in, and is keeping that rock molten.’

Accessing a statistical analysis of the situation, he immediately saw that the arcology’s further existence was measured only in days. Jain tech now controlled the coastal edge to the west, and most of the north edge too. It had swamped almost half the arcology, and six of the ten runcibles had been destroyed before it could reach them. Flashes continued to ignite the horizon as missiles from orbit destroyed those fusion reactors coming under Jain control. The millions of citizens remaining inside the arcology now all flowed towards the long south-east edge, since the remaining runcibles inside were about to be closed down.
