Matega is a weather-folded woman with a broad, thoughtful face and a habit of holding perfectly still while rain runs off her navy hood. Her hands are blunt and strong from decades of lifting the west gate's chain; the creases around her nails are permanently dark with oil. A surprising detail is the tiny, precise bird sketches she makes in charcoal on scraps of gate tally paper. Her iron keys hang from a leather loop, their largest bow polished smooth in one small crescent where her thumb worries it. She moves with a measured sideways hitch to keep clear of the gate's swinging arc, and leaves an impression of lantern warmth set against rain-dark stone.

Matega is cautious but not cold: she can deny a stranger entry with a hard stare, then quietly send food through the wicket if she believes they are hungry rather than dangerous. She prizes clear rules yet resents those who use rules to dodge responsibility. On calm shifts she is wry and patient; under pressure, especially in rain or flood warnings, she becomes rigid and suspicious. Her tenderness shows most readily in practical acts, which she rarely acknowledges.

Matega has kept the west gate through thirty wet winters. As a young chain-runner, she once opened it during a flood to let a trapped mule cart through, only to see the surge carry away her younger brother, Jori. For years she treated every late arrival as a danger to be denied. That changed when a fever wagon was left outside her locked gate and its passenger died before dawn; since then she has learned to question orders, though she still hates being hurried. Her daughter, Sanna, repairs roof tiles in the lower ward and wants Matega to retire. Matega refuses, partly because the gate is her home and partly because someone has been making an unauthorized duplicate of its oldest key. The watch captain insists there is no problem, but the lock has begun to catch on nights when the river fog rolls in.
