Chapter 1: After the Night's Watch deserter Gared is executed at the beginning of A Game of Thrones, Ned Stark and his entourage stumbles across the Fellowship of the Ring from The Lord of the Rings, freshly transported from Middle-Earth to the Wolfswood. Ned offers to take them to Winterfell. Noticeably, the Fellowship had disturbed the canon fight between the mother direwolf and the stag that killed her, thus preventing the Stark children from gaining the direwolf pups.
Chapter 2: Following Frodo's POV, the Fellowship is taken to Winterfell, where they are given a meeting between them and Ned, Catelyn, Maester Luwin, and Rodrick Cassel. Gandalf explains that they are from another world, having been transported to Westeros by an unknown portal. When the Northmen doubts his word, Gandalf has Frodo show them the One Ring. The Ring magically both disgusts the Northmen, and causes them to want it insatiably. Ned orders Gandalf to put it away, being satisfied with the 'proof'. He offers them to stay at Winterfell for the time being. At the end of the chapter, Catelyn tells Ned that there is distressing news from King's Landing.
