Princess Rhaena Targaryen was the second daughter of King Aegon III Targaryen and his second wife, Queen Daenaera Velaryon. The sister of both King Daeron I Targaryen and King Baelor I Targaryen, at the age of fourteen, Rhaena became known as one of the Maidens in the Tower when Baelor imprisoned her and her sisters.
At fourteen, two years younger than Daena, Rhaena was just as lovely as her sister, but hers was a softer, sweeter, more feminine beauty. Though by no means plump, her body was more rounded than Daena's. Her breasts were larger, her lips fuller, her hair more gold than silver and always carefully coiffed and combed. She had soft, kind eyes and a shy, sweet smile. Personality wise she differed quite alot from her older sister. Where Daena was wilful, wild, and adventurous, Rhaena was dutiful, meek, and passive. She loved lace and gold trim and often embroidered depictions of faith on her clothing.
Rhaena was the second daughter of King Aegon III Targaryen and Queen Daenaera of House Velaryon. She was born in 147 AC. She had two brothers, Daeron and Baelor, and two sisters, Daena and Elaena. Rhaena, along with her sisters, was one of the infamous sisters of King Baelor I Targaryen. By Baelor, she and her sisters were locked in what would since then be known as the Maidenvault, becoming known as the "Three Maids in the Tower". Baelor imprisoned the sisters in comfortable confinement so the sight of them would not tempt him or others in his court to mortal lusts. Rhaena, unlike her two sisters, never chaffed at her confinement. She was heavily influenced by her brother Baelor and in later life even joined the Faith and became a Septa.
The second daughter and fourth child of King Aegon III Targaryen, Rhaena was the granddaughter of Princess Rhaenyra Targaryen and her uncle-husband, Prince Daemon Targaryen. Rhaena never married, due to joining the faith, and thus did not have any children herself.
