Jeyne Arryn

Lady Jeyne Arryn was the Lady of the Eyrie and head of House Arryn during the Dance of the Dragons.

Biography
When Prince Jacaerys Velaryon flew to the Vale on his dragon Vermax to seek allies for his mother Rhaenyra, Jeyne upheld her house's oath to support Rhaenyra's claim to the Iron Throne. The armies of the Vale were thus sworn to her in the civil war against her brother Aegon II Targaryen.

In the books
Lady Jeyne became Lady of the Eyrie during the late reign of King Jaehaerys I Targaryen, while still in her minority, and Lord Yorbert Royce ruled as Lord Protector, attending the Great Council of 101 AC in her stead. When Lady Rhea Royce died, her husband Prince Daemon Targaryen appealed to Jeyne to be granted House Royce's seat of Runestone, but Jeyne rejected him and ordered him to leave the Vale.

Apart from the fact that House Arryn had already sworn to support Rhaenyra's claim, Lady Jeyne also supported Rhaenyra due to the fact that she was part Arryn herself, being the daughter of Aemma Arryn. While the snows closed the passes in the Mountains of the Moon, Jeyne sent her troops south by way of ship from Gulltown. After being driven from King's Landing, Rhaenyra was counselled to take refuge with Jeyne in the Vale by Ser Harrold Darke, but she refused this advice.

After the war, Lady Jeyne served as one of the original seven regents for Rhaenyra's son and the new king, Aegon III Targaryen. She died of an illness in Gulltown in 134 AC.
