Senex Sector
an area of the galaxy found in the Outer Rim Territories, it had been ruled by a number of familial houses since it was first settled. It was located near the Juvex Sector and the Ninth Quadrant, and was connected to the rest of the galaxy by the Rimma Trade Route. During the Old Republic, Senex Sector was an independent entity that maintained its autonomous stance with the agreement of the Republic. The open acceptance of slavery by the many Houses that controlled the Senex Sector, especially Houses Vandron and Elegin, was what prevented the Republic from accepting Senex Sector as a full member of the Republic.
