The Seswenna sector was a sector in the Outer Rim territories situated at the intersection of the Rimma Trade Route and the trans-galactic Hydian Way. The sector was where the Seswenna Security Crisis originated, with its roots in the rivalry between then-capital Seswenna and Eriadu. The sector was put on alert 705 BBY when the B'Rhea-led Mint Revolution swept the Arrain Makila into exile and reorganized the government into an authoritarian complex. The actions of Eriaduans Avar Zranik and Torrik Samit became a focal point in the crisis that spread throughout the galaxy.
