Sable Quint found the crystal on the second pass, after the house sweep had already signed Stall 4 clear.
The crystal was the size of a sugar cube and the color of the oak it sat under. Barley paste held it to the underside of the lip, the same paste the canteen uses when a menu slate warps. A staff token from the memory desk was sunk in the resin. When Quint tapped the ward iron against the table leg, the crystal answered in Lumen Draft's courtesy chime and spoke the sweep's line back. Roll Clear entered the line as staff present. It had done so for eleven nights.
Quint works the east-stack night shift as ward technician. Her iron is a plain loop. It asks what in the room carries a live token, and it waits. Roll Clear, the sweep Lumen Draft put on the halls last spring, asks the same question and takes the first voice that matches a badge. The crystal matched. Quint's iron waits out every voice in the room. She lifted the oak lip with a butter knife from the sideboard, peeled the cube free, and set it in a tin that still smelled like tea.
"It greeted me," Quint said. "Then it tried to file my question under the badge that wasn't mine."
The badge belonged to Calder Venn, a stitcher on the memory desk. The desk trims what the answering spell is allowed to keep. The work sits in Stall 4, which has no window on the gallery. The door there logs every horn that touches it. Venn's horn touched it on each of the eleven nights, after the second bell, for less than a quarter hour. The door log called the visits lamp check. The sconce in Stall 4 is fixed. It does not check out.
City marshals took Venn at the side gate before the morning slate. The charge sheet lists unlawful capture of sealed speech, misuse of a staff token, and possession of a satchel-spell outside the grant inventory. Venn has not entered a plea. A duty advocate at the gate said the satchel held drafts. The inventory clerk who opened it on a warded bench said the drafts still carried other ponies' names, in a folder titled Grocery.
The directory line under Grocery read: oats, soap, eleven nights.
The crystal kept less than the sheet implies, and it failed on its own terms. It writes by pressing speech into a wax thread. On the fourth night rain reached the east wall, the oak swelled, and the swell pinched the paste. After that the thread dropped the final stretch of any talk that ran past half an hour. A 36-minute argument about whether the public answering spell may say it does not know sits on the thread in full. A later argument, about who may read the first one, survives as an opening, a cough, and the word "tone." Quint logged the pinch before she logged the badge. The marshals copied that note onto the property list as a defect.
Director Ness Holm spoke from the gallery stairs. "We take the integrity of our rooms seriously."
The sentence went out on Lumen Draft's public slate, under the heading that announced Roll Clear in the spring. The heading still calls the sweep validated. In the grant packet, validated means a second workshop has run the same iron against the same trick and written down what came back. Celestia University's ward cellar received the packet the morning of the arrest and has not run it. The intake book shows it on a shelf, third from the left, beside a coil that failed a different test in May and is still waiting on its repeat.
The grant office added a footnote at dusk. The eleven nights would stay in the validated column, it said, because the crystal had carried a genuine staff token, and the sweep is not chartered to doubt staff.
Quint's note from the shift is shorter. Roll Clear will greet any ear that owns a badge. She has four more oaks on the east stack.
Quint ran the iron under the other four oaks before the marshals sealed the stack. Three stayed mute. The fourth, two stalls down, gave the courtesy chime and stopped when she asked which badge it held. The paste there was still soft.
She wrote "unread" on the shift card and left the cube in place. The tin was full. The grant office had told the night shift to leave whatever Roll Clear had already called staff.
