Yavin IV is one of many moons orbiting the Gas Giant Yavin Prime, the only planet of the Yavin Star System. It is a lush habitable world covered entirely by jungle and rainforest. Despite being remote and unpopulated, it has been the site of many a notable galactic event including being the refuge of Naga Shadow whose army actually built the Massassi temples which were later used by the Rebel Alliance during the Galactic Civil War as strongholds from where they launched the famed assault on the First Death Star.
