Jeyne became Lady of the Eyrie at some point late in the reign of King Jaehaerys I Targaryen, while she was still in her minority. During the Great Council of 101 AC, she did not attend. In her stead went Lord Yorbert Royce, who served as Lord Protector during this time.
On the death of Lady Rhea Royce in 115 AC, her husband Prince Daemon Targaryen appealed to Lady Jeyne in the hopes of claiming Runestone for himself. Jeyne not only rejected his claim, but also ordered him to leave the Vale.
At the start of the civil war called the Dance of the Dragons, Prince Jacaerys Velaryon flew north on his dragon Vermax, to foster allies for the cause of his mother, Rhaenyra Targaryen, herself the daughter of Aemma Arryn. One of the places he went to was the Eyrie. There, he treated with Lady Jeyne and made a promise to her. Jeyne brought the Eyrie to the side of the blacks during the civil war. Though snows closed the passes through the Mountains of the Moon, Jeyne sent men by sea by way of Gulltown to join the queen's hosts. When Rhaenyra fled King's Landing following the riot of King's Landing and the storming of the Dragonpit, Ser Harrold Darke of the Queensguard urged her to seek refuge with Lady Jeyne in the Vale. Rhaenyra, however, was determined to return to Dragonstone and refused his council.
Lady Jeyne served as one of the original seven regents to Rhaenyra's eldest surviving son, King Aegon III Targaryen, following the conclusion of the civil war. She died in 134 AC of an illness while in Gulltown.
