Princess Daenerys was born in 172 AC to Queen Naerys and King Aegon IV and was the younger sister of King Daeron II Targaryen. Prince Maron Nymeros Martell was the ruling Prince of Dorne and younger brother of Myriah Martell, the wife of Daeron II.
The wedding between Daenerys and Maron was held in King's Landing in 187 AC and formally made Dorne part of the Seven Kingdoms. After the ceremony, Maron kneeled before the Iron Throne and togehter, Maron and Daeron II went to pay their respects to the statue of the late King Baelor the Blessed at the Great Sept, who had once brokered the peace between the Iron Throne and Dorne via the marriage of Daeron II and Myriah. To celebrate the wedding, a tourney was held in the capital. Daenerys and Maron had multiple children and the eldest child, a son, presumably succeeded Maron as ruling Prince of Dorne.
In Dorne, Maron built his bride the Water Gardens three leagues to the west of Sunspear. It was a place of beauty made of colored marble with pools and trees to free her from the heat and dust of Sunspear. Their children played in the pools along with the children of other highborn lords and ladies. One day, when the sun was hot, Daenerys took pity on the children of the servants and guards and allowed them to play in the pools with the highborn children, starting a tradition that is still kept in Dorne to this day.
