Tessa is a broad, compact Talus-Dweller Oread with the weight and steadiness of a river stone. Lichen stipples her rough, slate-brown skin, and pale salt crust gathers at her hairline after a long day outside. Her forward-curving horns are wrapped in dried kelp, its brittle edges ticking softly when she turns her head. She moves with deliberate, sure-footed steps, placing each boot as if testing a river crossing. Her unexpected habit of making tiny, careful paper boats from discarded notices gives her an oddly playful air amid the village disputes.

Tessa is patient with frightened people and impatient with preventable waste. She can be warm at a crowded meal, making room for strangers with a practical kindness, then become stubbornly exacting when someone treats the estuary as an inexhaustible resource. She prefers peace, but does not confuse peace with letting a powerful person set every term.

Tessa grew up among the turf-and-basalt homes of Kelpmead, learning tide tables from fishers and plant lore from her mother, who tended the estuary beds. When she was young, a commercial dredging crew cut through a nursery channel despite warnings from local Keepers. Tessa joined the rescue effort as the Sour Floods carried silt and dead fish through the village; the following season’s failed catch taught her that patient stewardship could matter more than a dramatic victory. She later helped persuade estuary villages to pause fishing together, a compromise that gradually drew kelp-farmers and herbalists into the Brine-Keepers. Now elected Reeve, she mediates between the settlement and trade interests seeking wider access to the waterways. Her apprentice, Oru, wants her to be bolder; barge captain Dema argues that her restrictions are costing families their livelihoods. Both are right often enough to trouble her.
