The Archive of the Thornkeepers occupied a tower so old that the Academy had stopped trying to date its foundation stones. The stones themselves seemed indifferent to the question. They had been there before the Academy. They expected to remain after.
Caelindra arrived at dawn, before the archivists began their daily cataloguing, which meant she had the stacks to herself. She needed primary sources on ward failures — not the theoretical treatises the Academy distributed to first-year students, but the incident reports, the field notes, the hasty marginalia written by Keepers who had stood at a failed threshold and tried to describe what they were seeing before the memory became too frightening to keep precise.
She found what she needed in the seventh sub-basement, in a set of leather folios labeled simply 1601–1612. The decade of the Last Disruption. She had read about it in her training. She had not, until now, read the firsthand accounts.
The entries were spare and technical in the way of people who had learned not to dwell. Ward status, atmospheric readings, personnel present, anomalous observations. But one phrase repeated across six separate reports from three different regions, written by Keepers who could not have communicated with each other in the time between their observations.
The iron remembers nothing.
She sat with that phrase for a long time in the dusty quiet of the Archive. Then she wrote it in her own notebook, pressed her thumb against the ink before it dried, and went to find someone who might explain what it meant.
