Rifthold is the capital city of Adarlan. Much of the conflict in the Throne of Glass series happens in Rifthold.
The city is protected by large, white walls and floored with cobblestone streets. The Avery River flows through Rifthold, with the harbor opening into the Great Ocean. The harbor contains warships, merchant vessels, and fishing boats. A large, lower class occupies the slums, giving the city a constantly dirty and spoiled odor. It also contains a shopping district. The glass castle is its crowning achievement, housing the royal family. Built above the original stone castle, it is an enormous crystalline structure with numerous towers, bridges, and turrets in addition to large, domed ballrooms and various wings.[1] It contains 600 rooms, military and servants' quarters, three gardens, a game park, and two stables.[2]
