The Dornish Marches, or simply the Marches,[1] are an area of southern Westeros in the border region north of Dorne.[2] The marches are predominantly in the southwestern stormlands and extend east to the Sea of Dorne,[3][4][5] although much of the western marches are within the Reach.[6] People from the region are known as marchers,[7] and they are ruled by marcher lords.[8]
