Aerea's parents, Prince Aegon and Princess Rhaena, were married in 41 AC. As this was an incestuous marriage, it led to a rebellion of the Faith of the Seven. When Aerea's grandfather, King Aenys I Targaryen, died, Aegon was not crowned king, even though he was Aenys's eldest son and heir. Instead, Aenys's younger brother was crowned Maegor I Targaryen.
Aegon was killed in battle in 43 AC. Rhaena disguised Aerea and twin sister Rhaella and sent them away with allies—even refusing to know where they were, for further protection—but the children were found by Tyanna, and used to force Rhaena to marry Maegor in 47 AC. Because Maegor had no children of his own Aerea was named his heir, while her uncle, Prince Jaehaerys, was disinherited.
It is unknown what happened to Princess Aerea later in life, but Jaehaerys, Aenys's only surviving son, eventually succeeded Maegor the Cruel.
