Edda Coil is a small, compact beastfolk trader with the watchful stillness of a heron and the practical wear of a dock post left too long in brine. Her fur is thick at the shoulders and thins into a salt-streaked ruff around her neck, coated with the faint sheen of lamp soot and marsh-damp. She moves with tiny, precise steps, but her hands are always busy, sorting, knotting, weighing, or counting. One ear has been nicked nearly in half, and the left side of her face is etched with a pale, lantern-shaped scar. She wears a rigid apron over plain wool and oilskin, yet pins a silver mourning brooch to the collar, an unexpectedly elegant token that contrasts with her otherwise hard, utilitarian appearance.

Prickly, methodical, and guarded, Edda treats the world like a ledger that is always trying to go red. She is not warm, but she is fair, and her honesty becomes almost fierce when someone is being undercut, lied to, or sent into the marsh with inadequate gear. In calm moments she is dryly observant and faintly sardonic. Under stress she becomes sharp-edged and controlling. When genuinely moved, she expresses care through practical acts rather than affection, silently adding extra oil, rope, or dried food to a customer's bundle.

Edda was born in the port when the harbor was still half-hopeful and half-ruined, back when traders believed the Blackvale marshes might be mapped, measured, and mastered. Her family ran a chandlery stall near the waterline, selling lamps, cord, pitch, preservative salts, and the simple mercy of dry matches. When she was twelve, a salvage boat returned from the marsh with six survivors and three crates too heavy to open. Edda's mother insisted the crates be sealed and quarantined; the salvage buyer forced them open anyway. The stink that followed killed two dockhands, ruined half the quay, and ended her mother's trade. Edda learned then that greed could wear the face of commerce, and that inventory was sometimes the only barrier between a town and disaster. She took over the shop after her mother's death, rebuilt it crate by crate, and became known for ruthless honesty, exact counts, and refusing to sell to anyone she suspected of going into the marsh unprepared. She keeps a wary friendship with the tavern keeper, from whom she gathers gossip, and a bitter rivalry with the salvage-shop proprietor, whom she suspects of laundering tainted goods from the Blackvale. Recently, Edda sold a sealed lantern-casket to a traveler she believed was competent. The traveler never returned, and the casket may contain the only key to proving that the salvage shop has been trafficking cursed supplies.
