Thule was an arid mountainous planet within the in the Esstran sector of the Outer Rim Territories. The planet shared its name with a mercenary gang known as Thugs of Thule.
Millennia prior to the Clone Wars, Thule was ruled by the ancient Sith. The planet contained Sith ruins and artifacts, including a large temple.
Thule was a planet occupied by the Separatist Alliance during the Clone Wars to develop a Separatist droid factory. The Jedi Council sent Jedi Knights Iskat Akaris and Tualon Yaluna, as well as Jedi General Josk Nivar and a company of clone troopers led by Captain Spider on a mission to destroy said factory after getting the intel on where other droid factories were throughout the galaxy itself. During the trek, Iskat was in awe of a crystal from the Sith temple on the planet, but secretly pocketed it to avoid suspicion from Nivar.
Doctor Chelli Lona Aphra owned a certificate from the Imperial Institute for Archaeological Exploitation that gave her limited clearance to access Thule, a site of historical importance to the Galactic Empire, according to bylaws 22.750-23.018 of the Harvester Accords.
