The ensuing communication with the HK program was nonverbal, and Coloron’s analysis dissected it on many levels. The AI immediately began constructing a virtual map of the substructure overlaid on a map of the arcology. Further analysis revealed stashes of materials behind the line of advance, currently being made ready for easy conversion; energy being bled from fusion reactors and stored in laminar structures, both capacitors and batteries; sneaky mycelial extensions heretofore undetected; and subsumed humans armed and massing for advance. Coloron now checked the disposition of its own defences, and issued orders.

‘Azroc, that’s close enough, pull your forces out.’

The Golem was presently accompanying those of his forces busy incinerating the Jain tech spreading along the walls and through the floor of a long hydroponics chamber. Smoke layered the air from burning vegetation, and fluids pouring from broken tanks onto hot metal boiled up in dirty clouds. Within sight, figures still human in shape but no longer entirely human tried to work their way through. Squatting beside a small proton cannon standing on four insectile legs, Azroc glanced back towards the drone through which Coloron spoke.

‘You’re going to blow it?’ he asked.

Coloron replied, ‘Thellant has been captured, and now new tactical intelligence has become available. The substructure is massing for a push very near your current position and it could reach Runcible 5 within half an hour.’

‘Where do you want us now, then?’

Coloron transmitted directly into the Golem’s mind a simple map of the present situation. The infestation had started thirty miles in from the shore, and fifty miles in from the northern edge of the arcology. Runcible 5 lay the nearest to it, with 4 and 3 spaced evenly along the shore to the south and the same distance in from the sea. The AI did not want to send any more inhabitants to those runcibles as there were crowds enough there already, and Jain tentacles moved faster along the shore wall than elsewhere. Forty miles in from that row of three runcibles, again evenly spaced, lay 6, 7, 8 and 9. Another fifty miles further in lay 1 and 2. Runcible 10 was located well out of the way, in the recent north-eastern extension. On the map the Jain tech had completely taken over the north-west corner, and now lay only three miles from 5 and twice that distance from 6. Azroc’s forces were currently arrayed in a line cutting off that entire section—those last two runcibles at their backs.

‘Pull back to seven now. I will destroy five and six the moment the substructure reaches them. You have a minimum of thirty-four minutes.’

‘Okay.’ Azroc began signalling to his section commanders.

‘And, Azroc’

‘Yes?’

‘I am about to begin some sterilization.’

‘Understood.’
