Intro. Princess Daenerys Targaryen was the daughter of King Aegon IV Targaryen and his sister wife, Queen Naerys Targaryen, was born in 172 AD in King's Landing, her stillborn twin. Daenerys came into the world fifteen days after her paternal half-brother, Aegor Rios, and long after her brother Daeron, to the point that by that time Daeron was already married and had a son, Baelor, older than her. The birth left her mother almost dying, but she eventually recovered. She was the younger sister of King Daeron II Targaryen and wife of the Prince of Dorne Maron Martell, Lord of Sunspear.
