Sefa is a small, sturdy halfling with sun-browned skin, dark hazel eyes, and thick black hair braided close to the scalp so it cannot catch in rigging. She keeps her clothing meticulously mended, with colored stitches marking the cuffs and collar. Her hands are callused from rope, canvas, and weapon drills, and she wears a sailor's coat reinforced with narrow strips of leather. Within a minute of meeting her, most people notice her soft, deliberate voice and the way her eyes immediately inspect every knot, buckle, and loose thread nearby.

Sefa is observant, patient, and quietly practical. She speaks gently enough that people often lean closer to hear her, then discover that she has noticed every detail they hoped to conceal. She dislikes boastfulness, values competent preparation, and shows affection by repairing equipment without being asked. In danger, her voice becomes even softer and her instructions become precise.

Sefa grew up among sail lofts and crowded docks, where a halfling's height made the high rigging seem impossibly distant and the work below deck seem endless. Her mother taught her to cut canvas, her uncle taught her to splice rope, and an old boatswain taught her that every knot tells the truth about the person who tied it. Sefa became a sailmaker and rigger, working from the foredeck with a bone needle, waxed thread, and an uncanny memory for every patched seam on a vessel. She learned to hear trouble in the creak of a line and to spot tampering where others saw only weather damage. When a merchant vessel lost its mainsail during a storm, Sefa climbed the rigging with a coil of spare canvas strapped to her back and held the torn sail together long enough for the crew to reach shelter. The captain afterward gave her a place in the ship's fighting drills, saying that anyone who could keep a vessel alive in a gale deserved to know how to defend it in harbor. Sefa took naturally to the disciplined rhythm of the fighter's life, though she still prefers a quiet deck, a sharp needle, and a well-tied line to any grand display of heroics. She now travels wherever honest work and suspicious rigging can be found, quietly correcting knots and loudly objecting to anyone who endangers a crew for profit.
