Sky Ridge Island, a mountainous landmass, was situated to the north of Horizon Island on the planet Rishi. It served as the location of a village inhabited by the indigenous Rishii species. During the Galactic War, the Order of Revan constructed a stronghold on this island. The diverse ecosystem of Sky Ridge Island's valleys and rivers included creatures such as Grophets, skar'klas, mud crabs, and krak'jyas, and it also contained deposits of the precious mineral exonium.
