Queen o' whores
Appearance and Character
The prostitute has large, heavy breasts, ample hips, and blond hair. She is crudely spoken.
A Feast for Crows
Ser Jaime Lannister visits the captive Edmure Tully on the gallows during the siege of Riverrun. When Ser Ryman Frey arrives with his whore, both are drunk and the woman's breasts are exposed. Ryman has crowned her with the crown of Robb Stark, taken by House Frey after the Red Wedding. While dismissing Ryman from the siege, Jaime tells him he may take his whore, but not her crown.
Ryman is hanged by outlaws while returning to the Twins. After being captured by the brotherhood without banners, Brienne of Tarth sees Lady Stoneheart holding Robb's crown. The fate of Ryman's prostitute is unknown.
Prostitute: Who in seven hells is this one?Ryman crowned me his very self. I'm the queen o' whores.
