Shortly after abandoning Sandor Clegane, Arya Stark arrives in Saltpans on horseback, and seeks out Ternesio Terys, captain of the merchant galley, the Titan's Daughter. Once she shows him Jaqen H'ghar's iron coin and utters the code phrase "valar morghulis", she is allowed aboard the ship and leaves Westeros.
In the books
In the A Song of Ice and Fire novels, Saltpans is a town in the Riverlands that sits on the Bay of Crabs and is the seat of House Cox. Saltpans has never been an important trading port but ships do call there from time to time. A small castle dominates the town, overlooking the harbor.
When Arya arrives at Saltpans, she sees that most of the shops and inns and alehouses around the harbor have been plundered or burned, though some still look inhabited.
In A Feast of Crows, it is revealed that Rorge, Biter and five more members of the Brave Companions formed a gang that sacked Saltpans. The atrocities they have committed were exceptionally savage, far worse than anything The Mountain and Amory Lorch and their men ever committed: women were raped and mutilated, children were butchered in their mothers' arms, half the town was put to torch. Among the victims were: a twelve-year-old girl promised to the Faith who was raped by Rorge, then was mutilated by the other gang members who cut her nose and nipples off; a woman who had been raped a dozen times, before she was given to Biter, who ripped her breasts apart with his teeth. Moreover, Rorge had previously been castrated as punishment for past rapes he had committed, but he nonetheless raped large numbers of women in Saltpans with sticks: not even for sexual pleasure, but simply because he sadistically enjoyed the brutality. Since Rorge wore the Hound's helm, it led to false rumors that the Hound led the attack.
The sack of Saltpans is mentioned repeatedly throughout the fourth novel. The High Sparrow relates it to Cersei in order to emphasize the need to restore the Faith Militant. He implies the Lannisters are responsible, for the Hound was their soldier. Cersei has no sympathy for the victims of the sack, and is angered by the implicit accusation. She offers that King Maegor's laws disbanding the Faith Militant will be cancelled by royal decree, and in return the High Septon will acknowledge Tommen as king and forgive the Crown's debt to the Faith, and he agrees.
