Brienne of Tarth

Ser Brienne of Tarth was a knight of House Tarth the only daughter of Lord Selwyn Tarth. From a young age, Brienne distanced herself from the societal norms expected of a girl of noble birth, and trained to become a skilled warrior. At the outset of the War of the Five Kings, Brienne pledged herself to King Renly Baratheon and was eventually named to his Kingsguard. After Renly's death, Brienne pledged herself to Catelyn Stark, and was soon after commanded to return a hostage Jaime Lannister to King's Landing in exchange for Catelyn's daughters, Sansa and Arya Stark. Brienne succeeded in returning Jaime only to learn that Arya was missing and Catelyn had been killed. Sansa soon after fled King's Landing during the Purple Wedding, but Jaime outfitted Brienne so she could find Sansa and take her somewhere safe. Brienne ultimately succeeded in doing so and served as Sansa's advisor and bodyguard during her campaign to retake Winterfell, as well as the Great War. On the eve of the Fall of Winterfell, Brienne was knighted by Jaime Lannister, making her the first female knight in the history of the Seven Kingdoms. After the Battle of King's Landing, Brienne was released from her oath to the Starks and named to King Gendry's Kingsguard as the Lord Commander.
