The Under-Registry was located in the belly of the Aethelgard Municipal Library, three floors below the level where the sunlight died. It was a place of high humidity and low expectations. To the city council, it was a graveyard of clerical errors. To Elara Vance, it was the city's true diary.
She spent her Tuesday mornings here, wearing silk gloves to handle the vellum maps of the "Old City." Aethelgard hadn't been built; it had been secreted, layer by layer, like a pearl.
"You're looking for the ghost-flues again," Marcus, the archivist, wheezed. He was a man who seemed to be composed entirely of tobacco smoke and archival dust.
"The Chancery is breathing wrong, Marcus," Elara said, her eyes tracing a line of copper-plate ink from 1844. "The ventilation system was designed for a building with four floors, but the blueprints show five. There's a lung missing."
Elara's obsession wasn't just academic. She believed that the physical state of a building influenced the souls of its inhabitants. A building with hidden rooms created people with hidden lives.
As she left the library, she felt the familiar itch of being watched—not by a person, but by the city itself. The newly installed Oculus cameras perched on the streetlamps like predatory birds. She tilted her chin down, her wide-brimmed hat casting a shadow that she knew, through Julian's anonymous tips, was exactly the right angle to confuse the facial recognition software.
