Stoneheart
Lady Catelyn Stark was killed by the Frey’s at the Red Wedding and then brought back to life by Baeric Dondarrian. It seems that death has changed Catelyn. She is less gracious and forgiving than in life and is consumed with a desire for vengeance on anyone she thinks betrayed her and her son, Robb. She hangs any men associated with the Freys, Boltons, or Lannisters, even if they had nothing to do with the “Red Wedding”.
Her appearance has been altered as well, with her flesh becoming soft and the color of curdled milk due to her corpse being submerged in river water for days. Half of her hair is gone and the rest is white and brittle. In addition, her wounds have not healed with her face covered in scratch marks and her throat still slit open. To speak she must cover the wound on her throat and even then she is difficult to understand.
