John Snow

Jon Snow, born Aegon Targaryen, is the son of Lyanna Stark and Rhaegar Targaryen, the late Prince of Dragonstone. From infancy, Jon is presented as the bastard son of Lord Eddard Stark, Lyanna's brother, and raised alongside Eddard's lawful children at Winterfell. Jon's true parentage is kept secret from everyone, including Jon himself, in order to protect him from those that sought the complete annihilation of House Targaryen.

Jorah Mormont

Ser Jorah Mormont was an exiled Northern lord from Westeros, previously living in Essos. He had sworn fealty to his fellow exile Daenerys Targaryen, the Targaryen claimant to the Iron Throne, and was the first to help her adapt to life as a khaleesi of the Dothraki.

Originally, Jorah was working as a spy for Varys, King Robert Baratheon's spymaster, sending him information about Viserys Targaryen's efforts to reclaim the throne. However, he grows to respect and admire Daenerys, serving her in earnest. After preventing an assassination attempt on Daenerys, he stops sending reports to Varys, ignoring an official royal pardon that would allow him to return to Westeros. He also developed strong, but unrequited, feelings for his queen.

Sandor Clegane

Sandor Clegane, popularly known as the Hound, was the younger brother of Ser Gregor Clegane and the personal bodyguard of Prince Joffrey Baratheon. When Joffrey ascended the Iron Throne, Sandor was named into his Kingsguard (despite not being a knight), but deserted his post at the Battle of the Blackwater. After traveling as a fugitive with Arya Stark, having a close brush with death following an altercation with Brienne of Tarth, and the mass murder of a congregation he attempted to find peace with, he reluctantly joined the Brotherhood Without Banners in hopes of having a greater purpose

Theon Greyjoy

Theon Greyjoy was the youngest son of King Balon Greyjoy of the Iron Islands and the younger brother of Rodrik, Maron, and Yara Greyjoy. Following his father's failed rebellion against the Iron Throne, Theon is taken as a ward (initially hostage) to Lord Eddard Stark of Winterfell. After Eddard's execution in King's Landing, Theon pledges his loyalty to Eddard's eldest son, King Robb Stark, in the subsequent War of the Five Kings, but ultimately betrays Robb and sides with his father in invading the North. Theon takes Winterfell from Robb's brother, Bran, but eventually is betrayed by his own men, which leads to his capture by House Bolton. He is tortured and forced into servitude by Ramsay Snow, who turns him into a broken pet named Reek. Theon, however, redeems himself by helping Ramsay's wife (and Robb's sister), Sansa Stark, escape from Winterfell and find refuge with her "half-brother" Jon Snow. The two later retake Winterfell, defeating Ramsay and House Bolton.

Jaime Lannister

Ser Jaime Lannister was the elder son of Lord Tywin Lannister, younger twin brother of Queen Cersei Lannister, and older brother of Tyrion Lannister. He was involved in an incestuous relationship with Cersei, and unknown to most, he was the biological father of her three bastard children, Joffrey, Myrcella, and Tommen, as well as her unborn child. During Robert's Rebellion, Jaime killed Aerys Targaryen, earning the derogatory nickname "Kingslayer." He was pardoned by Robert and allowed to serve in his Kingsguard. Following King Robert's death, he was appointed as the Lord Commander of the Kingsguard to his son, Joffrey.

Robin Arryn

Lord Robin Arryn, called "Sweetrobin" by his mother, is the only surviving child and heir of Lord Jon Arryn by his wife, Lysa of House Tully, who served as Robin's regent during his minority. He is the Lord of the Eyrie, the head of House Arryn, the Warden of the East and Defender of the Vale.

Margaery Tyrell

Queen Margaery Tyrell was the only daughter of Lord Mace Tyrell and Lady Alerie Tyrell, granddaughter of Lady Olenna Tyrell and sister of Ser Loras Tyrell. Margaery became Queen Consort through her marriage to King Joffrey Baratheon, and later his younger brother, King Tommen Baratheon, following Joffrey's death. However, a charge of perjury and a false dedication to the Sparrow movement led to her downfall as she was eventually killed along with her brother and father when the Great Sept of Baelor was destroyed with wildfire as orchestrated by Cersei Lannister to reclaim her lost power.

Robert Baratheon

King Robert I Baratheon was the seventeenth ruler of the Seven Kingdoms and the first king of the Baratheon dynasty. Robert also had two younger brothers, Stannis and Renly. He and Cersei had three children: Joffrey, Myrcella, and Tommen. However, unbeknownst to Robert and most of the realm, all three were actually fathered by Cersei's twin brother, Jaime Lannister. On the other hand, Robert had many bastards from other women, including Gendry and Barra.
