Cassandra Baratheon was a noblewoman from House Baratheon during the reign of kings Viserys I, Aegon II and Aegon III Targaryen. She was the eldest of the four daughters of Lord Borros Baratheon of Storm's End. She and her sisters were known as the Four Storms.
At the start of the Dance of the Dragons, Prince Aemond Targaryen arrived at Storm's End. Lord Borros offered the hand of any of his daughters, noting that Cassandra would be the first to flower. Prince Aemond agreed, though the identity of the daughter is not known, save it was not Maris. The lord and prince were haggling over dates and dowries the morning Prince Lucerys arrived, and claiming he could not marry Cassandra or her sisters due to his betrothal to Rhaena Targaryen, and was sent away by Lord Borros.
Later, in return for the support of Ser Perkin the Flea and the stormlords in restoring King Aegon II to the Iron Throne, Queen Alicent Hightower agreed that the king would marry Cassandra Baratheon. As the king's sons, Prince Jaehaerys and Prince Maelor had both died, Aegon II wished to marry Cassandra Baratheon at once after retaking the Iron Throne, and have sons on her.
It is said that Lady Cassandra wept when she learned that Aegon II had died and that she would not be a queen.
Lady Elenda sent Cassandra, Ellyn, and Floris to represent House Baratheon at the coronation of Aegon III Targaryen and his wedding to Princess Jaehaera. Cassandra became a lady companion to the new queen after the wedding. When Jaehaera was found dead on the moat of spikes below Maegor's Holdfast, some blamed Lady Cassandra. Her detractors claimed that the disappointment at not being a queen had turned her sour, and bitterly resented having to care for a weepy and feeble-witted queen whom she blamed for all her woes. After Jaehaera's death, Lady Elenda put Cassandra and Ellyn forward as potential queens for Aegon III. The rumor that she had murdered Jaehaera was heard again before the Maiden's Day Cattle Show, likely due to the actions of Lord Unwin Peake, who hoped to further his own daughter as a marriage candidate for the king.
When Aegon III married again to Queen Daenaera Velaryon, Cassandra became her companion. When the king and queen suffered an attempted poisoning, she confessed that she had often shared her bed with Ser Mervyn Flowers, and sometimes with Tessario the Tiger at Ser Mervyn's behest. When Willam Stackspear suggested Cassandra was a reward Tessario was promised for killing Jaehaera, Cassandra burst into tears.
Lady Elenda had sent three Baratheon bannermen to speak for Cassandra during her trial. Through them, and Lord Lorent Grandison, Cassandra was spared the harsher punishments of Lucinda Penrose and Priscella Hogg due to her high birth. Instead, she was arranged to marry the minor knight Ser Walter Brownhill, thirty years her elder and who had fathered sixteen children in total upon three previous wives. Through caring for Ser Walter's thirteen living children and the additional sons or daughters she might give him, Lady Elenda thought Cassandra's plotting would cease, and it did.
