The only members of the house to appear are Ser Aron Santagar, master-at-arms of the Red Keep, and Sylva Santagar, the heir to the Knight of Spottswood, Ser Symon Santagar.
Ser Aron was killed by rioters in King’s Landing, his head crushed. Lady Sylva, a close companion of Arianne Martell, was a part of her conspiracy and was captured with her and most of her other conspirators. She was sent on to Greenstone to wed the elderly Lord Estermont.
