Vesper Quill is a tall, narrow Aarakocra with soot-black feathers at the shoulders fading into silver-gray flight feathers at the wingtips. Their plumage has the dry, velvety texture of old theater curtains, and loose feathers constantly tremble around the throat whenever they hear someone lie. Vesper moves with careful, theatrical economy, folding their wings like a cloaked actor between gestures, then snapping into sudden birdlike stillness when listening. Their beak is polished dark ivory and marked with tiny ink stains from years of holding quills between their teeth. Within a minute of meeting them, most people notice that Vesper's breathing is almost inaudible until they become upset, when each breath arrives as a soft chorus of other people's exhalations. The contradictory impression is striking: they look like a solemn omen, but their eyes sparkle with the restless amusement of a street performer who has just thought of a joke.
