Seylin is a compact halfling with a dancer's balance and a pickpocket's stillness, always seeming to shift her weight as if standing on an invisible rope. Her bright orange hair is a wild, ember-bright cloud that refuses pins and ties alike, but she has braided thin silver threads into it so it flashes like coins in a firelight gust. Her green eyes are quick, amused, and a little too observant, as if she is forever cataloging exits, pockets, and lies. Her skin is warm beige with faint freckles across her nose and forearms, and her hands are narrow, elegant, and scarred by old harness burns and lockpicks. She dresses in layered traveling silks over soft leather gear, but the sleeves and hems are reinforced with hidden stitching and weighted thread. The contradictory detail is that she carries herself with stage-trained grace while keeping her boots dust-caked and practical, like a performer who hates being mistaken for one.
