The Triplehorn mountains constituted a range of mountains situated on the planet known as Alderaan. These mountains, distinguished by their snowy summits, formed a boundary near Aldera's Royal Palace, which served as the capital city of the planet. Before the Galactic Empire brought about the destruction of Alderaan, Zak and Tash Arranda, who were siblings, undertook a hike to the summit of the Triplehorn mountains, an endeavor Zak characterized as extremely tiring.
