Craster's wives are a group of about a dozen women married to the wildling Craster and who dwell with him in his homestead in the Haunted Forest. Some (if not all) of Craster's wives are also his own daughters, whom he "marries" once they have flowered. Boys born from these couplings are sacrificed by Craster to the White Walkers, while daughters are kept to serve him and marry him once they are of age - to produce more daughters to marry.
