The United American Starzone (UAS), commonly known as the American Starzone or American Arm, is a collection of systems located in the north 'western' area of the Sundula Starzone. The core of this civilization consists of four star systems with ancient marii 'fast' jump gates and three outer colonies with human manufactured jump gates. The UAS also controls numerous 'unlinked' colonies along its frontier with varying degrees of development and population sizes.
