Three days later, Catelyn's body is washed ashore downstream along with hundreds of other corpses, and a wolf pack led by Arya Stark's stray direwolf Nymeria is drawn to scavenge upon the dead. However, Arya is skinchanging into Nymeria at the time during her sleep, recognizes her mother's body, controls Nymeria to pull it out of the river and guards it against other wolves until the outlaw band Brotherhood Without Banners passes by to repel the wolves. Catelyn is then resurrected by Lord Beric Dondarrion, who sacrifices his life force to revive her in repayment to her husband Eddard's honoring. However, the period of time she spent deceased has caused Catelyn's body to partly decay, disfiguring her looks; furthermore, upon her reanimation she loses most of her previous kind personality, except for her hatred of the Lannisters and the Freys. Catelyn then assumes command of the Brotherhood, and changes their aim to terrorizing anyone related to House Frey and Lannister. Her uncompromising brutality earns her the moniker "Lady Stoneheart".
