Sister Setiva was an older, female shrew who was known for her Northern accent. She was a very strict Infirmary keeper and she was made fun of by Bragoon and Saro once because of her extreme control. Setiva carried the Blackthorn Stick, which she later lent Martha Braebuck, and wore a shawl. She had a thin, reedy voice. Later she learned to translate the speech of Buffle.
