The Wendwater is a river located in the southeastern crownlands and northeastern stormlands, marking a border between the two regions within the Seven Kingdoms. It is the largest river in the kingswood.
Beginning at a narrow lake in the southern kingswood, the Wendwater flows northeast to Blackwater Bay. North and west of the Wendwater is the forest of the kingswood, while to the east is Massey's Hook. According to semi-canon sources the seat of House Wendwater is located along the river in the kingswood.
Aegon Targaryen, Lord of Dragonstone, angered the Storm King, Argilac Durrandon, by asking for lands between the Blackwater Rush, the Wendwater, and the Mander. Prior to the Last Storm, the host of Orys Baratheon was attacked by Lords Errol, Fell, and Buckler in an ambush on the Wendwater.
A Clash of Kings
En route to King's Landing, Stannis Baratheon's fleet anchors at the mouth of the Wendwater. Ser Imry Florent, Lord High Captain of Stannis's fleet, calls for a meeting of captains to instruct them in the battle plan once they reach the Blackwater Rush. Three days later they attack King's Landing in the Battle of the Blackwater.
