Catelyn married Ned Stark after King Aerys executed Ned's brother, Brandon, to whom Catelyn was betrothed. Though she barely knew Ned at the time of their wedding, their love has grown strong over the years, and as the Lady of Winterfell, Catelyn has raised his five legitimate children. Her husband's bastard, Jon Snow, however, is an embarrassment she has refused to accept.
Eddard "Ned" Stark
A stoic, duty-bound and honorable lord, Ned Stark embodies the values of the northern realm over which he rules. Seventeen years ago, he left his home to rise up against the Mad King Aerys Targaryen , fighting alongside his longtime friend Robert Baratheon, who took control of the throne after the war. As Warden of the North, Ned returned to Winterfell with his bastard son, Jon Snow, who despite joining the household, has never been accepted by Ned's wife, Catelyn Stark.
As the oldest Stark son, Robb is heir to Winterfell, and very aware of the responsibilities that come with his title. Despite being the house's most important son, Robb has a close relationship with his bastard half-brother, Jon Snow, and is on good terms with Theon Greyjoy, his father's ward from the Iron Islands. His direwolf is named Grey Wind.
Sansa has inherited her mother Catelyn's beauty, which should serve her well in the courtly world of knights and princes she dreams of inhabiting. But growing up in the northern reaches, where the only hardship she experiences are taunts from her sister, has left Sansa somewhat sheltered, and her naiveté won't help her in the world outside Winterfell's walls. Her direwolf is named Lady.
A young girl far more interested in wielding a blade than becoming a lady, Arya is constantly at odds with her prim sister, Sansa. Arya is very much her father's daughter, and Ned has a certain level of appreciation for the girl's rebellious attitude... up to a point. Her direwolf is named Nymeria.
Young Bran dreams of becoming a great knight while his brother, Robb, rules over Winterfell. The boy's natural curiosity and infectious humor endear him to all the members of the Stark household, though those same traits can land him in precarious – even dangerous – situations. His direwolf is named Summer.
A ward of House Stark, Theon came to Winterfell when he was 8. His wardship at Winterfell serves to ensure that his birth family will not take arms against the Starks and was initiated after his father, Balon Greyjoy of the Iron Islands, led a failed rebellion for independence against King Robert. Theon has reached a friendly detente with the Starks, but his cavalier actions and swaggering style contrast greatly with the staid ways of the North.
