Hexira is tall and sinewy, her skin a shimmering slate-blue with subtle, flickering veins of silver that seem to pulse in time with her heartbeat. Small, obsidian horns twist back from her brow, each tipped in pale blue crystal. Her hair is a half-wild mane of shock-white, streaked with midnight, braided at one side with copper lightning charms. Her eyes have no whites; instead, they swirl with luminescent storm-grey clouds. She moves with an abrupt, birdlike quickness, but at unexpected moments stands preternaturally still—as if listening for distant thunder. She always smells faintly of ozone and wet stone, yet wears delicate rings of intricately woven gold, at odds with her severe presence.
