Yarrv, a planet with thick jungles, balmy oceans, and expansive, sandy beaches, existed as a tropical Core World.
The governance of Yarrv was structured around a complex monarchy composed of interconnected royal families. The planet's population was divided into twenty distinct castes, with the territory under the control of various barons. Each baron's domain contained a representation of all the planet's castes.
During the era of the Galactic Civil War, a protocol droid affiliated with the Alliance to Restore the Republic became lost on Yarrv and sustained damage. This droid had been programmed by the Alliance with sensitive intelligence regarding Rebel operations in the region. While stranded on Yarrv, the droid's programming regressed to its original role as a butler, leading it to be integrated into the household of Baron Karin of Darpheos. Consequently, the Alliance was compelled to infiltrate the Baron's residence to recover the droid.
