Coloron knew of some, either Separatist related or suffering from severe troglodytism, who were not obeying the evacuation order. Many of them remained inside the infested area, within reach of Jain tentacles, and many had already been taken over. Little could be done for any of those. From cameras on the particle weapon geostationary above, the AI studied the circular chunk of arcology it had initially excised in the hope of containing the Jain tech. The cavity near the centre of this, made by the Coloron’s first satellite strike, looked like a bullethole filled with steel maggots. The trench cut to separate out the piece of arcology in which this hole lay also squirmed with movement as Jain tech increasingly bridged the gap.

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.
