The Riverlands

The riverlands is a central region of the Seven Kingdoms of Westeros, consisting of the rich, fertile, and populous areas around the three forks of the Trident and the northern Blackwater Rush. At the time of Aegon's Conquest the riverlands and the Iron Islands were ruled by House Hoare, the Kings of the Isles and the Rivers, although native river kings ruled centuries earlier.

Because of their central position in Westeros and lack of natural boundaries, the riverlands have been a frequent battleground. The people of the riverlands are known as "rivermen" or occasionally "riverlanders", and they are a mixture of hardy warriors, peaceful fisherfolk and devout smallfolk. Their lords have a reputation for being notoriously quarrelsome, and are referred to as "river lords". Noble bastards born in the riverlands are given the surname Rivers.

The riverlands are ruled from Riverrun by House Tully, the Lords Paramount of the Trident. Notable houses of the region include Blackwood, Bracken, Brune of Darry, Frey, Mallister, Mooton, Piper, and Vance.
