A leader in the Left Hand of the Jhereg. Caola is the sorceress in charge of a group that was attempting to gain control of the Jhereg activities in South Adrilankha after the Jhereg boss in the area lost authority over her businesses while trying to subdue them. Her group's activities were centered in a private house in the Six Corners district on Number Eleven Strangers Road, which was formerly owned by an old woman called Coletti who died a year before. Their project also aimed to position Terion in the Right Hand Council because of his connection with Triesco.
