  ===The North===
  The detachment of the Night's Watch under Lord Commander Jeor Mormont are attacked by undead wights and the Others, hostile inhuman creatures from the far north. The Watch suffer heavy casualties, although the steward Samwell Tarly kills one of the Others with a blade of obsidian. Soon some of the Watch mutiny and kill Mormont, but Sam escapes with the help of a wildling girl, Gilly. Sam, Gilly, and Gilly's newborn child approach the Wall, assisted by a strange figure riding an elk, whom Sam calls Coldhands. Among the dead are most of the Watch's senior leadership.
  Robb's brother Bran and his friends, having escaped the Boltons' attack on the Stark castle Winterfell, are guided north by Bran's dreams of a three-eyed crow. At the Wall, Sam guides them to Coldhands and returns to the Night Watch's headquarters at Castle Black, having sworn to keep Bran's survival secret even from Jon Snow, Bran's bastard brother and Sam's fellow Watchman.
  Jon, on a mission to infiltrate the wildlings, convinces Mance that he is a deserter from the Night's Watch, and learns that the Others are driving the wildlings south towards the Wall. Jon and his captor Ygritte also begin a sexual relationship. After crossing the Wall, Jon escapes the wildlings and returns to Castle Black. The approaching wildling army attacks Castle Black; but Jon takes command of the defenses and repels several assaults, during which Ygritte is slain. After that, the Watch's surviving leaders Janos Slynt and Alliser Thorne falsely accuse Jon of treachery, and send him north of the Wall to kill Mance under a pretense of parley. As Jon is talking with Mance in the wildling camp, Stannis' army arrives, routing the Wildlings, and Mance is imprisoned. Stannis offers to legitimize Jon and make him Lord of Winterfell in exchange for his support, but Jon decides to decline Stannis' offer, and is elected by the Night's Watch as its new Lord Commander.
