House Tully
From Asoiaf
House Tully has held the castle of Riverrun for a thousand years though they were never kings. They were first subjects of the River Kings who ruled the land around the Trident. The last River King was slain by the Storm Kings who conquered all the way to the Neck. Three hundred years later Harwyn Hardhand, King of the Isles, took the Trident from King [Arrec]]
