The Lambda sector was a sector located in the galaxy's Mid Rim, and contained the Ando system, home of the Aqualish species, as well as the planet Rintonne. During the Clone Wars, about half of the sector defected to the Confederacy of Independent Systems, led by Senator Po Nudo and the Hyper-Communications Cartel. However, most of the Andoan Free Colonies and Rintonne remained loyal to the Galactic Republic.
