The Crownlands are the lands in Westeros surrounding King's Landing, ruled directly by the crown of the Iron Throne. The Targaryen kings consolidated this as one of the nine regions of Westeros, after their conquest of the Seven Kingdoms, from sparsely populated pieces of the Riverlands and Stormlands. The Crownlands form the entire coastline of Blackwater Bay, and include the original Targaryen homeland on the island of Dragonstone, at the Narrow Sea entrance to Blackwater Bay. Besides King's Landing, which is the largest city in Westeros, the Crownlands include many towns and castles. The illegitimate children born in the Crownlands are given the surname Waters.
