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.
