High Chunah was a planet on the Corellian Trade Spine in the Greater Javin region of the Outer Rim Territories. Once an outlying colony world of the Mugaari species, High Chunah became a profitable speeder-manufacturing planet once the Galactic Republic capitalized on the region's economic potential. High Chunah was best known for the phosphorescent rocks littering its surface, which gave the planet an unusual green glow when seen from space.
