He once planned to reveal the truth about the betrothal to Arianne, and was going to send her to the Free City of Tyrosh to serve as a cupbearer to the Archon of Tyrosh and secretly meet with Viserys.However, Doran abandoned that plan due to suicidal threats from Arianne's mother Mellario, who was already deeply upset that Quentyn had been sent away to be fostered.

When Arianne reached the age of marriage, Doran presented her with several suitors, all of whom were elderly lords (including Ben Beesbury, Walder Frey, Gyles Rosby, Eldon Estermont, and Hugh Grandison), while rejecting an offer from Lord Hoster Tully, who had invited Arianne to travel to Riverrun and meet his heir Edmure.

Arianne refused all of the elderly suitors, and asked to travel to Highgarden to meet Willas Tyrell.

While Oberyn showed Tyene the best way to milk a snake's venom, and Sarella went exploring, Arianne sat on a rock, dreaming that a tall, hard robber knight, with black eyes and a widow's peak, had taken her there to have his way with her.

However, when Arianne was fourteen years old, she stumbled across a half-written letter from Doran to her younger brother, Quentyn, who was being fostered at Yronwood.

Princess Arianne Nymeros Martell, better known simply as Arianne Martell, is a member of House Martell and is the eldest daughter of Doran Martell, the ruling Prince of Dorne, and his consort, Lady Mellario of the Free City of Norvos.

According to Dornish customs, she is the heiress of Sunspear, and the future ruling Princess of Dorne.

Arianne spent several years of her early life at the Water Gardens.

She had two younger brothers, but since Quentyn was sent away as a page to Yronwood at an early age and Trystane was eleven years younger than herself, Arianne was never close to them.

Arianne is a POV character in A Feast for Crows and The Winds of Winter.

Now a woman in her early twenties, Arianne is buxom and beautiful, with olive skin, large dark eyes and long, thick black hair that falls in ringlets to the middle of her back.

Prince Doran, who seemingly pursues a conciliatory approach, returns to Sunspear after having spent two years at the Water Gardens.
