Sater was the captain of the Suncurl despite seemingly having little nautical knowledge. She relied on first mate Ably Druther to know "which end of a ship points where we're going" and insisted her crew keep quiet about their port of origin and destination. Earlier in her life she had served as a captain in the Toll's City palace guards and as a bodyguard to the Factor of Swamp Thick. Sater had grey eyes and hair prone to tangling and knotting.
