Abrion Major droid factory

During the final years of the Clone Wars, the Confederacy of Independent Systems established a massive droid factory inside a large mountain on the planet Abrion Major. The entrance to the factory was located on a cliff of the mountain that led to a cave where the main doors were located. The facility contributed to manufacturing numerous battle droids in service to the Confederacy military during the final stretch of the war. During the Battle of Abrion Major, the 401st Legion destroyed the mountain with the factory inside after defeating the Separatist forces stationed to defend the factory site.
