The Stormlands are the Westerosi areas between King's Landing and the Sea of Dorne. In the east they are bordered by Shipbreaker Bay and the Dornish Sea to the south. Before Aegon's conquest they were ruled by the Storm Kings, and afterwards by House Baratheon, bastard relatives to the Targaryens. The Dornish Marches are located within this region, and were common battlegrounds between the Stormlands and Dorne until Aegon joined the Seven Kingdoms. Illegitimate children born in the Stormlands are given the surname Storm.
