The Orbital’s Hub had been the first thing to go, blitzed in an instant by a staggeringly bright CAM burst before there had been any warning whatsoever. Then the hundred or so major ships moored beneath the O’s outer surface, contained within Bulkhead Range docks or approaching or leaving the Orbital, had been destroyed in a single synchronised scatter-gun blaze, Minds precisely obliterated by exquisitely focused Line-gun loci, their already cram-packed substrates collapsing into particles more dense than neutron star material, all that prized wit, intelligence and knowledge-almost-beyond-measuring snuffed in every case to a barely visible ultra-dense cinder almost before they had time to realise what was happening to them.
While the shock waves from the gravity-point collapses were still propagating through the victim vessels’ internal structures and hulls, they were slammed with meticulously graded degrees of further destruction, the craft within or very close to the O targeted with small nukes and thermonuclear charges sufficient to destroy the ships themselves without compromising the strategic structure of the Orbital itself, while those further out were simply smithereened with anti-matter warheads, their megatonne bodies slashed across the outboard skies in blinding pulses of energy that threw jagged shadows across the vast internal surfaces of the world.
All of this in a handful of seconds. A heartbeat later the independent high-AI Defensive Nodes overseeing each of the O’s original Plates had been knocked out with pinpoint plasma displacements and simultaneously the few thousand nearby Interstellar-class ships were attacked, meeting their fates in a grotesque parody of size seniority; first the larger, more capable craft vanishing in nuclear or thermonuclear explosions, then the second-rank ships moments later, followed by smaller and smaller vessels until all those were gone and the blossoming waves of annihilation moved on to target the slowest, in-system craft.
Finally the semi-slaved AIs, dotted at random throughout the fabric of the entire bracelet world, had stopped communicating all at once, the weapon systems that they had fallen heir to as the higher-level control processes had been destroyed either subsiding to dormancy or actively starting to attack whatever defensive capability there was left.
Drones and humans taking command of independently controllable weapon and munition delivery systems made up what was left, the few machines and people in the right place at the right time scrabbling to take over from the blitzed machines even as they were struggling to comprehend what was happening to their world.
