  ====Riverrun====
  Riverrun is the ancestral stronghold of House Tully. The castle is located along one of the "forks" of the Trident and controls access to the interior of Westeros. The castle is bordered on two sides by the Tumblestone River and the Red Fork. The third side fronts on a massive manmade ditch. It was built by Ser Axel Tully on land he received from the Andal King Armistead Vance.
  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.
