Mira is a narrow-shouldered young woman with the stillness of someone accustomed to listening for danger beneath stone. She moves in small, exact shifts, never crossing a room directly when she can follow its walls. Her gaze rarely rests on a speaker's face. It travels instead to hinges, loose tiles, pockets, ceiling joints, and the hands of anyone holding a key. Her fingers are permanently darkened by ink, lamp soot, and mineral dust, with blunt nails polished smooth from years of handling brittle pages. She wears a calm expression that becomes almost severe when she is frightened. The unexpected contradiction is that her severe silhouette hides a soft, almost domestic tenderness: she carefully tucks stray threads back into other people's clothing and carries sugared fennel for frightened children.

Miri is patient with objects, guarded with adults, and immediately gentle with frightened children or animals. She can spend six hours restoring a damaged page but becomes irritable when someone asks her to explain her feelings for six minutes. She is suspicious of generosity from the powerful yet accepts help from strangers with startling faith if they show care toward the dead. In danger she grows quiet and practical. In safety she becomes unexpectedly wry, fussy, and almost playful. Her deepest tension is that she believes knowledge should belong to everyone, while secretly fearing that some truths can only harm those who learn them.

Mira was born above her mother's bookbinding stall in the river city of Veyr, where damaged ledgers and prayer books came to be repaired. Her father, a surveyor of old roads, vanished during an expedition into the salt hills when Mira was nine. The only thing recovered from him was a waterlogged index written in a cipher no one could read. At fourteen, Mira entered the sealed catacombs beneath the Hall of Measures to retrieve a stolen tax register for the city archivist. She found her father's cipher carved into a burial wall, along with proof that he had not died in the hills but had been searching for a hidden library beneath the tombs. A cave-in trapped her for three nights beside a dead expedition member and a box of blank books. By the time rescuers reached her, she had filled every book with observations, maps, and the names of things she heard moving in the dark. The experience changed her from a curious apprentice into a relentless investigator who believes forgotten knowledge becomes dangerous when left ownerless. She now works as a freelance investigator of ruins, quietly searching for her father's missing expedition and the library he died, or perhaps chose, to enter.
