Game of Thrones, based on George R. R. Martin’s A Song of Ice and Fire series, has an extensive cast of characters, each with their distinct backstories and complex relationships. Providing a comprehensive list of all characters in this series could be daunting due to its sheer size. However, I can give you summaries of some of the most influential characters: 1. **Eddard Stark "Ned"** - The Lord of Winterfell and Warden of the North. He is a close friend of King Robert Baratheon. 2. **Catelyn Stark** - Ned's wife, mother to his five children. 3. **Robb Stark** - Eldest son of Ned and Catelyn, assumed Lord of Winterfell. 4. **Sansa Stark** - Elder daughter of Ned and Catelyn, once betrothed to King Joffrey. 5. **Arya Stark** - The rebellious younger daughter of Ned and Catelyn. 6. **Bran Stark** - Second son of Ned and Catelyn, he becomes the Three-Eyed Raven. 7. **Rickon Stark** - Youngest of the Stark children. 8. **Jon Snow** - Ned's alleged illegitimate son, later revealed to be Lyanna Stark and Rhaegar Targaryen's. 9. **Daenerys Targaryen** - Last surviving child of King Aerys II, known as the "Mother of Dragons." 10. **Tyrion Lannister** - Youngest child of Tywin Lannister, often despised due to his dwarfism. 11. **Jaime Lannister** - Eldest son of Tywin Lannister, known as the "Kingslayer". 12. **Cersei Lannister** - Jaime's twin sister, later becomes the Queen Regnant of the Seven Kingdoms.
