SOPHIE

Ihave thirteen of the fourteen elements and the console won't take thirteen.

I try it anyway, because I'm a scientist and because I'm desperate, and the seat does something no Precursor system has ever done in my presence. It answers.

The whole interior writes one line, four meters tall, in a construction so old that the verb form is archaic even by the standards of the census wall.

Incomplete. Who returns.

"It's asking again," I say. Nobody is listening; Ansel and a pair of others hold the aperture rail with weapons trained on the shaft, and Zuri is beside me holding a reader she can't read. "It asked at the doorway and I answered and it let me in. Now it's asking properly."

"What's the difference?"

"The doorway wanted to know who was walking in. This one is asking who holds command."

Element fourteen is what I found this morning, in a quartermaster's note about lamp stock, and have not said out loud to a single person, including the man I told I loved him, and there's a reason for that, and the reason is getting worse by the minute.

So I do the work available to me, and the work is archaeology.

Because the protocol isn't merely incomplete. It has been taken apart.

I see it at 1530, forty minutes into the reconstruction, and once I see it I can't understand how I missed it. The thirteen elements I have aren't scattered by accident or decay. Four came from the substation shards. Three from the archive on the ninth. Two from the census wall. One from the manifests at Fourth Muster and one from a temple ceiling nine kilometers east, and each of them sits in a different installation under a different authority.

Nobody in this fortress could have assembled this alone.

"They split it," I say. "Zuri, they split their own shutdown protocol across eleven sites so no single commander could ever be forced to give it up."

"Forced by who?"

"By anybody. That's the point. You cannot torture a garrison officer into standing down a planetary gun if the officer physically doesn't have the whole answer." I'm laughing, which isn't appropriate. "A century of scholarship calling them warlords, and what they actually built was a chain of custody."

And it's that, precisely that, which gives me the last thing I need.

I have been treating this as a lock. Fourteen elements, turn them in order, the gun switches off. But you don't fragment a lock. You fragment a decision, and a decision needs somebody with standing to make it, and the seat has told me twice now in its archaic verb form that it doesn't want a password. It wants to know who holds command.

Which means I can't override this machine.

I have to convince it.

"Sophie." Ansel, sharp, from the rail. "Movement."

They arrive by the walkway, not the shaft. A pair of the four-meter kind, and Vesk puts everything he has left into the walkway approach and it isn't enough and it doesn't need to be, because that walkway is nine hundred meters of curve and every meter of it is time.

I return to the console.

I have three sub-elements missing out of the reconstruction and I find two of them in things I read days ago and didn't understand.

The eleven-notch discs. Every challenge arch down here runs on the district count, and I read that as a navigation quirk, and it isn't. It's a signature: each district signs with its own number. Element nine wants a district signature and I carry eleven of them in my head.

The census wall. Four hundred blank entries where fleets never signed, and among the last that did there's a repeated appended cluster that I read as a courtesy and dismissed. That is no courtesy. It's a rank.

By 1610 I have thirteen and a half elements, and the sphere has started to make a noise like an ocean a long way off, and Zuri says, very quietly, "Sophie, the count went past twelve."

"That isn't possible. Twelve is the top."

"Twelve was the ceiling of the readiness scale." She turns the reader around. "This is a different index. It started at zero four minutes ago and it's climbing."

Deployment is finished. What I'm looking at now is a firing solution, being assembled, at leisure, by something that has waited two hundred centuries to do its job properly.
