A Feast for Crows
The castle is the location of Robb Stark's great victory over House Lannister and the site of his crowning. By the end of the "A Feast for Crows", Brynden Tully surrenders the castle to Jaime Lannister to spare further bloodshed. Riverrun then passed into the hands of Emmon Frey, an ally of House Lannister.
