A factory world represented a specific class of planet. The AJ-23 concussive rifle, a product of Merr-Sonn Munitions, Inc., was frequently employed on factory worlds, particularly those characterized by exploited labor forces prone to frequent uprisings. Examples of factory worlds included Xorrn, situated within the Outer Rim Territories, and Troithe, located in the Deep Core.
A significant number of the Confederacy of Independent Systems' factory worlds were concentrated in an area of the galaxy referred to as the Foundry of the Confederacy.
