Lord of Riverrun
After having supported King Tristifer IV Mudd in many of his battles, Ser Edmure Tully went over to the Andal Armistead Vance. Vance granted Edmure's son Axel lands at the juncture of the Red Fork and the Tumblestone, where Axel build his seat of Riverrun.
A Storm of Swords
After years of illness, Lord Hoster Tully dies, and his son Edmure inherits Riverrun. Edmure travels to the Twins to marry Roslin Frey, but the wedding turns out to be a trap, as Edmure is taken captive after the bedding, and his sister Catelyn and king Robb Stark are slain.
A Feast for Crows
Edmure's wife Roslin Frey is pregnant, and prays for a daughter, since giving birth to a son could mean Edmure's execution. Riverrun is still being held by Edmure's uncle, Ser Brynden Tully, and soon finds itself besieged. Ser Ryman Frey threatens to hang Edmure if Riverrun is not surrendered, and makes Edmure stand at the gallows every day, but fails to make good on his threats. After months of siege, Ser Jaime Lannister of the Kingsguard arrives, giving Edmure the chance to peacefully surrender the castle, which he eventually does.
