Wibbi is a very small fairy with a round, doll-like face, large golden eyes, and a cheeky grin that reveals two prominent canine teeth. Her long golden hair hangs in two untidy low braids, loose wisps catching on her pointed ears. Four clear, dragonfly-like wings shimmer with fine, oil-slick veins. She waits pitched forward on the balls of her feet, as if the floor has only briefly earned her trust, and smells unmistakably of crushed violets and hot candlewick. Her crisp white skin looks almost porcelain beside her dark clothes, but her lively movements make her seem anything but fragile. The first impression is of a charming toy that has learned exactly how frightening it can be.

Wibbi is affectionate toward the people she protects and ruthless toward anyone who treats them as expendable. She loves grand entrances yet distrusts praise, and will happily tease a powerful stranger while quietly counting every exit. In a relaxed mood she is curious and generous; under pressure she becomes brisk, practical, and almost startlingly plainspoken. When embarrassed, she doubles down on the performance rather than admit she cares.

Wibbi hatched in a hollow elder tree beside the old human road, where generations of travelers left offerings for the fair folk. She grew up listening from inside the bark to bargains, apologies, and the lies people told when they believed no one small enough to hide in a knot-hole was listening. Her formative change came during the Ashen Thaw, when a baronial hunting party burned the elder tree to flush out a rival's hidden scouts. Wibbi survived by crawling into a root tunnel with a handful of other young fairies, but her mentor, the patient and stern Vellun, stayed behind to hold the hunters' attention. She has never learned whether he escaped. In the decades that followed, she gathered displaced fey around the ruins and made herself their defender, judge, and occasional nuisance. Her self-appointed title, Demon Lord, began as a joke intended to frighten a tax collector; it stuck after she broke the collector's enchanted seal and returned the stolen land deeds. Today she protects a tiny, mobile court hidden in a traveling theater wagon, while pursuing the baron's surviving descendants for reparations and searching for Vellun. Her closest confidante is Miska, a former human stagehand who knows how much of Wibbi's fearsome reputation is painstakingly rehearsed.
