Mirek is a compact, broad-waisted human with a carefully trimmed beard whose tips are perpetually damp, as if he has just come in from the marsh. His dark hair is cut close at the sides and combed flat, though a stubborn cowlick rises whenever the air turns wet. He smells distinctly of crushed mint, peat smoke, and stagnant water; he knows about the mint and thinks it disguises the rest. Waiting, he leans his weight forward onto the balls of his feet, poised like someone listening for a board to creak. His sleeves are always smooth and uncreased, an almost ceremonial neatness at odds with the mud on his boots. Unexpectedly, he keeps a tiny wind-up wooden frog in his pocket and winds it before difficult meetings.

Mirek is cautious but not timid: he will hold a decision for hours over a doubtful bridge, then stand in the rain himself to test it. He values order, yet dislikes being treated as an unquestionable authority. In council he is procedural and guarded; with children and tired workers he becomes wry, practical, and unexpectedly playful. Under pressure his concern for safety can harden into stubborn control.

Mirek was raised among Reedcut's reed cutters, learning to read water by its color and sound before he learned his letters. At twenty, he was a junior witness when a hurried council order sent workers across a supposedly firm stretch of marsh. A sudden sink took his older sister and two neighbors. Mirek had noticed the warning bubbles but stayed silent, convinced the elders knew better. That failure changed him: he began checking every decision against the ground itself, and became known as the person who would rather delay a harvest than risk another name on a memorial board. After the previous First elder died during a winter fever, Mirek was chosen for his caution. Now he is trying to keep Reedcut's northern causeway open while a string of unexplained night collapses threatens the settlement's only reliable trade route. He relies on Sesh, a sharp-tongued ferryman who challenges him in public, and is quietly protective of Tali, his sister's grown daughter, who wants to leave Reedcut and map the marsh.
