Fading afternoon light slanted through the open back kitchen doorway behind Sister Merrow’s kitchen. It mixed with the yellow glow of an animal fat dip to light up the brass frame of the Courtesy Arch. Junior Town Examiner Corvin stood three feet from the brick pier, his academy wool cloak folded neatly over a sawhorse and his bronze-rimmed glasses pushed down his nose. In his left hand he held his open audit ledger. In his right, the brass butt of his dip pen tapped a slow, careful rhythm against the discontinuous rune tracks of the arch.
Pella Rook sat on a three-legged milking stool beside the slate desk, unlacing her mud-stiffened boots after the long walk down from the South Gate. Meanwhile, Foreman Eren Tal stood at the vise truing the edge of an ash firmer chisel. The washroom smelled of roasting chicory root, damp pine shavings, and iron dark oak-ink—the quiet, domestic scent of a workshop winding down for the evening—until Corvin cleared his throat.
‘Your mass limits are checked to a tenth of an ounce, Pella, and your one-to-one clockwork gear catch has zero measurable drift,’ Corvin said, his finger tracing the deliberate three-inch gap in the bronze power-coil loop above the keystone. ‘In a standard academy binding circle, if an external force shatters the stone ring while a spirit is showed up, the holding snaps inward like a parted thick ship rope and shears the entity across the threshold.’
