Keth moves with the poised, forward-leaning balance of someone always feeling for the next gust. Her fine, pebbled scales lie close across her face and neck, while the larger scales on her shoulders catch the light like overlapping roof tiles. A stiff scarlet crest sweeps back from her skull in uneven vanes, trembling whenever she tests the air. Her jaw is long and narrow, crowded with small recurved teeth; when she laughs, the corners of her mouth pull wide before the sound arrives. Her breathing is a quick, dry rasp through the nose, usually measured into short bursts. Under pressure, those breaths click sharply against her teeth, and she clamps her jaw as if biting down on the wind. An unexpected habit for a cliff-runner: she keeps a tiny clay pot of sprouting greens clipped inside her harness and checks its leaves before every flight.

Keth is bold in motion but conservative in planning. She enjoys a sharp contest and will take a difficult route when the odds are honestly understood, yet she cannot tolerate someone gambling with another person's life for applause. Among trusted pilots she is teasing and physically demonstrative; with strangers she is brisk, watchful, and hard to impress. When ashamed, she becomes more exacting rather than more withdrawn.

Keth grew up among the Sunlit Reach's rope bridges and freight platforms, where one missed knot could send a week of food spinning into the mist. As a young courier, she trusted instinct more than instruments and once pushed a glider into a gap-wind that tore its wing spars apart. Her mentor, Seli, survived the crash but lost the use of one leg. Keth changed after that: she began mapping gusts, teaching apprentices to call out what they saw, and insisting that every escort plan include a retreat route. During the Long Squall, she helped coordinate the Wind-Rider Brotherhood's warning flights that turned freight gliders away from a storm funnel. The work made her second-in-command, but her methods bring her into conflict with older pilots who prize daring over caution. Now she oversees cliff-face scouting posts near High-Arch Spire, while trying to keep Seli's small courier station solvent and prevent a powerful freight concern from pressuring the Brotherhood into unsafe schedules.
