Viessa possesses a striking, ethereal beauty that feels barely tethered to the ground. Her skin is a pale blue-gray that constantly shifts like morning mist, with darker charcoal swirls appearing when she is stressed. Her hair is a mane of translucent white-blue that floats upward as if she is permanently underwater or caught in a vertical updraft. Her eyes, which she calls stormglass, are a dark, polished gray that crackles with tiny, visible sparks of yellow electricity when she uses her magic. She moves with a weightless, bouncing grace, often appearing to 'fall' toward her destination rather than walking. In contrast to her airy nature, she wears heavy, utilitarian sky-iron bracers that ground her silhouette.
