Ramiro was silent; he had nothing to bargain with. If he went to the Council and helped them mount a defence against the occulters, he’d only be risking a far greater loss of life from a meteor strike.

‘Why?’ he asked, dropping any pretence that there was still some doubt about Giacomo’s plans. ‘The disruption is enough. The Council will be humiliated, they’ll fall at the next election. The system will never be restarted. What more could you want?’

Giacomo embarked on a long, loud story about someone’s feud with someone else in their student days. Ramiro began to think that the meeting was over; he finished his meal and began picking up crumbs from the plate.

But then the story ended and Giacomo spoke.

‘This is the fulcrum,’ he whispered. ‘This is our one chance. Or how many generations will be forced to bear the same ruthless people holding power? Prisoners locked up without trial? Men treated as lesser beings, made for one purpose alone? The disruption is not enough; there needs to be damage and chaos. The Council needs to fail the people so badly that they don’t dare set foot on the mountain again. Let them run away to Esilio or die in their private fortresses. In two days everything will change for ever. There’s nothing to lament in that. But if we want our time to come, there has to be a price.’

Ramiro lay sleepless in his sand bed, staring out into the moss-lit room. If the messaging system’s tubes were breached, their walls might still hold against the pressure. The Council would have known all along that this kind of damage was possible; they must have taken steps to minimise the consequences.

But all the earlier construction along the axis had been carried out with no conception that it would ever be exposed to the void. Walls could be strengthened after the fact, seals could be laid down. But nothing would ever render the resulting patchwork the same as the solid rock of the hull that had been kept intact for that purpose from the start.

If the tubes gave way, whole precincts would crumble. People would be battered by the winds and debris, even if they didn’t end up out in the void. Before the breach could be repaired there would be all the damage and chaos that Giacomo could desire.

But what other possibilities remained? Ramiro could still summon up a slender hope that if he went to the Council promising to reveal the details of the attack, they would agree to a voluntary shutdown. Maybe all the stubbornness Greta had displayed in public had only been for show.
