From A Wiki of Ice and Fire
In the Age of the Hundred Kingdoms, the kingdom of the western marches extended from Horn Hill to Nightsong. House Gardener of Highgarden united the western marches to the Reach proper, along with the Kingdom of the High Tower and the Kingdom of the Arbor, to form the Kingdom of the Reach.
Horn Hill and Nightsong are now part of the Dornish Marches within the Seven Kingdoms. Although Horn Hill remains part of the Reach, Nightsong is within the stormlands.
