Most of what I recognized as the starboard quadrant of the city was gone. That was bad, because what lay beneath that part of the visible city was some of Vox Core’s essential infrastructure. Vox was complexly interconnected, and in the past it had sustained major damage without loss of function. But even the most decentralized network will fail if it loses too much connectivity, and that was what must have happened when the nuke penetrated our defenses. It was as if Vox’s brain had suffered a massive stroke, the damage spreading and compounding itself until the whole organism lost function. Tendrils of smoke still wafted up from the impact point. A hole had been punched in the starboard wall of the city, which might have provided an entry point for Farmer forces, except that radioactive and still-smoldering rubble had barred the gap.

Treya had spent the whole of her life in this city, and her shock welled up in me and made my eyes water.

Turk—once he made sure Digger Choi was out of earshot—said, “Tell me about the people who did this.”

“Built the city or dropped the bomb?”

“Dropped the bomb.”

“An alliance of cortical democracies and radical bionormatives. They were determined not to let us cross the Arch. Scared we’ll call down some kind of doom by attracting the attention of the Hypotheticals.”

“You think that might happen?”

It was a question Treya would never have entertained. Treya had been a good Voxish citizen, blithely convinced that the Hypotheticals were benevolent and that human beings could aspire to some kind of intercourse with them. But as Allison I could be agnostic about it. “I don’t actually know.”

“Sooner or later we might have to pick sides in one of these fights.”

That would be a luxury, I thought, to pick a side.

But for now the question was moot. We ate the pea-green gunk we had been given and stood up for a last look around before Digger Choi came to tie us up for the night. The sky had gotten darker and the peak of the Arch shimmered almost directly overhead. Vox Core itself had filled with shadows.

That was the saddest thing of all, it seemed to me: the darkness of Vox Core. All my life (Treya’s life) the Core had been ablaze with light. It leaked light like a glorious sieve. Its light was its heartbeat. And now it was gone. Not even a twinkle.
