Rhaena was born in Pentos in 116 AC. When she was half a year old, she sailed from Pentos to Driftmark with her mother and twin sister. In 117 AC, she was presented at court by her father, Prince Daemon Targaryen. In 118 AC, with the blessing of King Viserys I Targaryen, Rhaena was betrothed, at the age of two, to Prince Lucerys Velaryon, her cousin. Rhaena and her twin sister, Baela, each had a dragon egg. When Rhaena’s egg hatched the hatchling was unhealthy and died within hours of emerging from the egg. Baela’s hatchling dragon was healthy, however. Before the civil war an egg from another clutch, laid by Syrax, was given to Rhaena, and it was said that she slept with it every night and prayed for a dragon to match her sister’s.
