After dissolving his marriage with his sister-wife, Daena Targaryen, King Baelor the Blessed confined Daena and her younger sisters, Rhaena and Elaena, into their own "Court of Beauty" to avoid them tempting him with carnal thoughts.
The sisters were comfortably confined in what has become known as the Maidenvault. On one occasion Elaena cut her beautiful hair in an entreaty to be freed, hoping that she would now be considered ugly. Daena escaped three times while dressed as a servant or smallfolk, and she became pregnant with a child, Daemon Waters, who was secretly fathered by her cousin, Prince Aegon. Barba Bracken was one of the noble companions for the sisters during their decade of confinement. Unlike her sisters, Rhaena did not mind the confinement. The princesses were released from the Maidenvault after Baelor's death.

Margaery stays in the Maidenvault even after her wedding to King Tommen I Baratheon. The Blue Bard performs for the young queen in the keep. Margaery and her cousins—Megga, Alla, and Elinor—attempt to learn a new game from Volantis, presumably cyvasse.
