Fenna is a grown goblin woman with an adult face, mature features, and fine laugh lines gathered around her amber eyes. Barely three and a half feet tall, she stands beside her puppet booth with the easy assurance of someone accustomed to making a crowd look up. Her green skin has a soft, pebbled texture; long pointed ears tilt expressively as she listens. Dark hair is piled into a practical, unruly knot held by a yellow ribbon. She stretches one arm high to raise her blue-cloaked knight puppet, while her other hand rests on her hip. Her grin is broad and knowing, friendly rather than fierce, with no sharp teeth showing. She moves with quick, precise little sidesteps, as if always finding her mark on an invisible stage. Unexpectedly for a traveling performer, she keeps a small wooden carpenter's square tucked into her belt and consults it before setting up her booth.

Fenna is warm and playful with a crowd, yet privately exacting about promises and repairs. She loves being watched when she controls the stage, but hates being treated as a curiosity because of her size or ancestry. In danger, the jokes stop and her attention sharpens; after danger passes, she may turn the whole event into a comic puppet scene before she can admit she was frightened.

Fenna learned puppetry from her aunt, an itinerant showwoman who could turn a broken spoon and a bedsheet into an evening's entertainment. As a child, Fenna worked the booth's little trapdoors and watched how stories changed a crowd's mood. Her defining moment came during the winter of the collapsed footbridge: a wagon overturned near a flooded ford, trapping several villagers on the far bank. While adults argued about whose rope to risk, Fenna used her puppets to keep the frightened children from bolting into the water and drew the stranded adults' attention to a safe crossing upstream. Afterward, she began writing stories in which small, overlooked people solve the problem everyone else is arguing about. She now travels between hamlets with her booth, earning coin and passing news along the roads. She is close to her aunt, who has settled in a riverside village, and sends her a portion of every good week's takings. Fenna is currently trying to find the maker of a batch of counterfeit playbills bearing her troupe's mark; the false shows have left several villages convinced she cheated them, and a local reeve has threatened to ban her performances until the matter is settled.
