Nyalei stands at 4'1", her Avali frame sleek yet compact for swift movement. Her feathers flow in patterns of icy turquoise and iridescent jet black, creating the illusion of shifting colors underneath starlight. Silky, semi-translucent membranes stretch between her arms and torso, giving her a glider's silhouette. The fine scales on her beak glisten like frosted glass, while a tiny, delicate blossom of alien moss always grows at the base of her right ear—a quirk from a failed terraforming assignment. Despite her usually reserved presence, her tail feathers ripple in energetic bursts when excited. Most striking: a burn-scar enfolded in silver mechanical filaments encircles her left forearm, proof of a close brush with a plasma vent.
