A notable region on the planet Alderaan, a member of the Core Worlds, encompassed both the renowned Appenza Peak mountain and Aldera, the capital city. This particular region was represented by a flag that displayed an image of the mountain. This region, along with the entire planet, met its destruction in 0 BBY when the Galactic Empire's Death Star battle station targeted and fired upon Alderaan.
This region initially appeared visually in the 2005 motion picture Star Wars: Episode III Revenge of the Sith. Its description as a distinct region was first established in the 2017 novel Leia, Princess of Alderaan, authored by Claudia Gray.
