Mara smells unmistakably of crushed fennel, wet wool, and the faint mineral tang of iron-rich creek water; she knows about the fennel, but not the rest. She moves with a careful, heel-first tread learned from crossing the Sickwood's soft ground, and when she stops, her head tilts as if listening for something beneath the floorboards. Her most unexpected feature for a village herbalist is a perfectly maintained set of tiny brass surveyor's calipers, which she uses to measure seed pods and splinters with the solemnity of a magistrate.

Mara is compassionate but guarded: she will treat a stranger's fever without charge, then ask who sent them and why they came by the river road. In calm company she is wry and patient; under pressure she becomes brisk, exact, and hard to distract. She wants people to trust one another, yet hides the very evidence that could help them decide what to do.

Mara was born in Candosville to a family of reed-cutters and learned remedies from her grandmother, who taught her to test every folk cure on herself before trusting it to a neighbor. At twenty-six, Mara joined a survey party sent into the Sickwood to find why the settlement's wells had begun tasting of pennies. She returned alone after a night of green rain, carrying a bundle of notes and refusing to explain why the party's leader had vanished. That ordeal changed her: she became meticulous about evidence, but now hesitates whenever a choice might put another person in the woods. Her husband, Sef, repairs eel traps and wants her to stop taking risks; their daughter, Tavi, quietly helps copy Mara's plant sketches. The settlement's reeve, Jorren, suspects Mara knows more about the woods' sickness than she admits. Lately, medicinal herbs near the old boundary have developed dark, glassy veins, while patients in Candosville dream of roots pressing against their bedroom walls.
