- "All of us chose to follow Yara. We left the Iron Islands for Yara. She would never leave one of us behind. We're not leaving her behind."
- ―Theon Greyjoy
The Rescue of Yara Greyjoy took place during the Great War and Daenerys Targaryen's invasion of Westeros when Theon Greyjoy set out to rescue his sister Yara, self-proclaimed Queen of the Iron Islands, from their uncle Euron, the King of the Iron Islands and an ally of Cersei Lannister.
- "Not for me. For Yara!"
- ―Theon, after rallying Yara's remaining loyalists
During Daenerys Targaryen's invasion of Westeros, while Yara and Theon were sailing the Dornish back to Dorne, their fleet was suddenly assaulted by the Iron Fleet led by Euron Greyjoy, who had made a marital pact with Cersei Lannister. Euron's ironborn quickly overcame Yara's and Theon's, and while Theon was able to escape by jumping overboard, Yara was captured by Euron and later paraded through the streets of King's Landing.
Theon was rescued by the few survivors of Euron's attack and they returned to Dragonstone. Yara's remaining followers had lost total respect for Theon, seeing him as a coward for running. However, Theon was able to regain their respect after he beat Harrag, one of Yara's captains, to unconsciousness and declared that they would rescue Yara from Euron.
Yara, meanwhile, is held captive by Euron on his flagship, the Silence. When Yara asks why he hasn't killed her yet, Euron says it's because she's family (despite being a kinslayer) and because he enjoys talking to her rather than his tongueless, mute crew.
While Euron Greyjoy is in the Red Keep with Cersei Lannister, Theon Greyjoy sneaks aboard the Silence docked in Blackwater Bay outside King's Landing with his men. They take out some of Euron's men with bow as they make their way to where Yara is being held captive, tied to a post. Theon kills the guard at the door with an axe and cuts her free. Yara knocks him to the ground for abandoning her before, but helps him back up for rescuing her. Together with their men, they escape the Silence.
Yara Greyjoy consolidates what remains of her fleet: three ships. She wants to sail to the Iron Islands and take them back from Euron, as this will give Daenerys somewhere to retreat to should the North fall, but Theon decides to go to Winterfell in the North instead, to help House Stark. Yara, as Theon's older sister and queen, consents to this, and the two exchange the saying "what is dead may never die" before embracing.
In the books
In the A Song of Ice and Fire books by George R.R. Martin, no equivalent event has occurred. Season 8 of Game of Thrones has surpassed the published books, so it is unclear if any similar event will occur in either of the remaining two books, The Winds of Winter and A Dream of Spring.
