Sebille is a tall and slender female elf assassin with pale skin, sharp features, and long pointed ears, her hair tied back. She wears a fitted dark leather fantasy outfit with a corset-like front and layered armor pieces. She is sneaking behind a wooden cargo, kneeling and holding a dagger in hand. The image is from side, and the art style is digital concept art with heavy brushwork. The background is in a dark medieval warehouse.
