Juno is the homeworld of the EDEN civilization and one of the most heavily defended Val-Fasq entrenchments prior to its liberation. Thanks to the efforts of Tact Mayers and the Moon Angel Wing, they were able to free Juno from the Val-Fasq after centuries of bondage. Juno housed the Library, an enormous databank of accumulated knowledge gathered by the EDEN culture. The Library was targeted by the Val-Fasq to delay the Transbaal Empire's involvement in stopping the creation of the Chrono Quake Bomb.

The EDEN universe's Chrono Gate is located near the planet.
