Ralston Ash looks like a travelling scholar who has spent too many nights sleeping beside roads and too many mornings taking notes before breakfast. His dark straw sun hat is softened at the brim and pierced through one side by a quill pen. A black sleeveless coat hangs over a red waistcoat gone shiny at the elbows; its hem carries a faint crust of road dust. His scruff is uneven, his dark hair curls around his ears, and his jaw shifts audibly when he chews, a habit made more noticeable by his broad, slightly crowded teeth. He smells of walnut ink, road-damp wool, and the sharp fennel lozenges he carries to keep his throat working. He knows about the ink and wool, but not the fennel. He walks with a musician's loose sway until he notices something worth recording, then stops so abruptly that whoever follows him nearly walks into his back. People remember the vivid red waistcoat, the smell of ink, and the way his eyes seem to be taking measurements.

Ralston is curious enough to interrupt a dangerous moment to sketch an unfamiliar lock, yet considerate enough to notice when someone has gone quiet and make room for them. He distrusts tidy official explanations but is sentimental about old songs and family rituals. Around strangers he is conversational and disarming; when a vulnerable witness is threatened, his humor vanishes and his questions become blunt. He wants to be a careful recorder, but cannot resist turning a good discovery into a public performance.

Ralston Ash was raised above a cramped bookbinder's shop in the river town of Kettig, where his mother repaired maps and his father played tavern tunes for supper. He learned to read from damaged atlases and learned to perform by watching which songs made exhausted travelers stop arguing. As a young man, he joined the itinerant scholars of the Rookery of Vetch, an informal society named for the weed that grew through its courtyard stones. There he copied local histories and performed ballads that made dry records memorable. His life changed during the winter of the Glass Flood, when a dam failed upstream and swept away the riverside quarter. Ralston spent a night helping survivors find shelter by calling out names and landmarks, only to discover later that the official account erased the poorer district and blamed its residents for the disaster. Since then, he has kept a journal of ordinary witnesses and places that formal histories omit. His old mentor, Tovrek, wants him to stop publishing accusations that could endanger the Rookery. His younger sister, Gitta, runs their mother's struggling shop and resents that Ralston's investigations keep bringing trouble to her door. Now a patron is paying him to locate a missing set of flood records, while a local magistrate is quietly trying to seize his journal.
