The thirteenth oracle was a child.
The register lists no name. The physician's log lists no age. The child had been left at the Sanctum by a traveler who did not leave a name either. The child did not speak. The Order assumed the child could not.
On the morning of the thirteenth onset, the child opened its mouth and spoke for four minutes. The physician recorded what the child said. The child described the end of the catastrophe.
Not the end the chart had predicted. The chart had projected the thirteenth position as a final cascade — the collapse settling into whatever configuration the broken world would hold. The child did not describe this. The child described what came after. The stillness. The Laboratory as it now stands. The archive. The shelves. The corridors where the pumps would run. The woman at the desk.
The child described the Librarian.
The page in the physician's log where this description was recorded has been removed. The cut is clean. The pages before and after are intact.
The child's voice did not change while speaking. The physician notes this. The child described the configuration of the broken world in the same flat tone with which an adult might describe a familiar room. The child had seen it. The child had been there a long time.
The child died that evening. The register's date was correct.
Entry 10,904, final annotation.
"The physician sealed the chart in the case that brought the register. The case is in the restricted section. I have located it. I have not opened it.
The thirteen positions, assembled, describe the breaking of the world. I do not need the chart to know this. I have read all thirteen accounts. I have followed the sequence the physician implied in his undated entry. The pattern resolves.
The catastrophe has not yet begun in our timeline. All thirteen are dead. The catastrophe has not occurred.
Or it has occurred and we are inside its duration, and the oracles were the last witnesses to remember it from the other side.
The physician's log describes what the child said about me. The page has been removed. I have searched the archive for copies. There are none. I have searched for the child's name. There is none. I have searched for the traveler who brought the child. There is none.
The register was filled in by no hand that worked in the Sanctum. I have compared it against every sample in my records. It matches none of them.
I have compared it against my own.
The comparison yielded a result I have filed elsewhere."
