The Inyusu Tor mineral processing facility, which is also referred to as the Inyusu Tor refinery complex, existed on the summit of the volcanic mountain known as Inyusu Tor located on the planet of Sullust. In the year 3 ABY, the Alliance to Restore the Republic's 61st Mobile Infantry seized control of this facility; however, they found themselves stranded on Sullust when their transport was destroyed. They successfully protected the complex from the Imperial forces stationed on Sullust, ultimately achieving a victory.
