Skyreach is carved into the stone which overlooks the Prince's Pass, the shortest and easiest route through the Red Mountains from Dorne to the Reach. The castle is known for its lofty perch and soaring towers.
When King Aegon I Targaryen invaded Dorne during the First Dornish War, he took Skyreach by storm. After Aegon returned to King's Landing, however, Skyreach was retaken by Dornish spearmen. After Lord Fowler burned Nightsong, Aegon vowed to make Skyreach a "second Harrenhal" and used the dragonflame of Balerion against the castle.
