Serenity is a tall half-elf with a soot-dark complexion that catches copper highlights beneath bright light. She moves with the careful economy of someone accustomed to carrying delicate mechanisms, placing her weight on the balls of her feet even while standing still. Her pale silver hair is braided with thin brass wire, tiny glass beads, and black thread, but loose strands constantly escape around her temples. Her eyes are sea-green and rarely settle on faces. Instead, they measure exits, ceiling beams, weapon belts, and the hands of anyone speaking. Her hands are broad-palmed and permanently marked with faint metallic freckles from years of working enchanted alloys. She smells faintly of cedar oil, rain, and burned sugar. The unexpected contradiction is her laugh, which is sudden, loud, and wholly undignified for someone whose presence otherwise feels quiet and controlled.
