The Stormlands, located south of King's Landing, stretch down to the Sea of Dorne, bordered by Shipbreaker Bay in the east and the Reach in the west. It is one of the smaller regions of Westeros, a land of harsh mountains, stony shores, and verdant forests.

Before Aegon's conquest they were ruled by the Storm Kings, and afterwards by the Baratheons, b*****d relatives to the Targaryens. The Dornish Marches are located within this region, having been conquered by the Storm Kings, and are ruled by House Caron and lesser marcher lords. The marches were common battlegrounds between the Stormlands, the Reach and Dorne until the last century, when Dorne joined the Seven Kingdoms. Bastards in the Stormlands are given the surname Storm.
