Lord of Winterfell and Warden of the North. The childhood friend of Robert Baratheon, he was a key player in Robert's rebellion, helping him win the throne from the Targaryens. He is married to Catelyn Tully.
Called 'The Imp' because of his small stature, he is the youngest son of Tywin Lannister, the richest lord in the Seven Kingdoms and younger brother to Queen Cersei and Ser Jaime Lannister. What he lacks in height, he makes up in wit.
Queen of the Seven Kingdoms and wife of King Robert. Fiercely protective of her three children, she also has an unusually tight connection to her twin brother, Jaime.
