When in the form of a woman or "girl", she has petite features with "enormous", black, lustrous eyes, and thin, pale lips which cover "white spiky fangs". Her skin is so pale that her hands seem "transparent". Her shoulder-length, black hair is "dishevelled", "tangled", and "windblown". She wears a flowing, white dress that trails behind her. She moves over the ground so lightly as to barely touch it, and leaves no tracks. When she runs it is like a "white streak" and her dress never snags on anything or slows her down. As she glides toward Geralt during the final moments of their battle, she is "white and black, windblown, terrible".
