A slim tiefling woman with polished crimson skin, swept-back black horns capped in brass bands, and a soot-stained tail ending in a delicate silver charm. Her dark hair is usually pinned up with spare gears and enamel clips, and she wears a tailored noble's coat over practical scale mail. Ink smudges, tool burns, and tiny rivets decorate her sleeves and cuffs like badges of honest work.

Elegant, exacting, and quietly curious, Seraphine treats every problem as a machine waiting to be understood. She is courteous by training, inventive by instinct, and just stubborn enough to keep going when her first plan fails.

Seraphine Voss was born to a family that understood appearances as well as ledgers. Her House was old, respected, and carefully managed, but Seraphine never cared for embroidery, etiquette lessons, or the endless theater of polite conversation. She cared about what made the clock in the hall keep perfect time, why a carriage axle failed under stress, and how a stove could be coaxed to burn hotter with the right arrangement of vents and runes. The family tolerated her eccentricities so long as she remained useful, and Seraphine learned early that invention was the only language in her house more respected than blood. Her tiefling heritage made courtly life a constant performance. Some guests spoke to her too softly, as if she were breakable. Others watched her horns and tail as though expecting a devil to slip free from them. Seraphine answered both with immaculate posture and sharper intelligence, then retreated to the workshop where brass, glass, and ink never judged her. When a cherished heirloom was ruined by a servant's mistake, she repaired it in secret with a clever hidden mechanism, and in that moment realized she would rather build wonders than preserve them. She left home with her signet ring, a noble's education, and the quiet determination to prove that a tiefling artificer can make the world more elegant, more efficient, and impossible to dismiss.
