A taciturn, dangerous wildling, Craster is considered an abomination by many other wildlings for his practice of wedding his own daughters, of whom Gilly is one. He is unfriendly to Mance Rayder and gives grudging aid to the Nights’ Watch, with rangers occasionally finding shelter at his “keep”. It’s said that Craster’s father was a ranger of the Watch who bedded a wildling woman of the village of Whitetree. He is powerfully built but white-haired with age, with a drooping mouth that gives him a cruel aspect. The actor cast in the role seems a reasonable fit for the character as described.
After the flight from the Fist of the First Men, Craster once more plays a very grudging host to the remanant of the Watch who are gathered there. Angry tensions rise among the men, who swear he has a larder of food he is holding back from them. Matters come to a head when one of the men of the Watch, Karl, takes hold of a daughter/wife of Craster and threatens her. Craster violently rises up, only to be brutally killed. Chaos ensus as Lord Mormont is also attacked and killed, leaving Samwell to flee into the night with Gilly and her newborn child.
