The Klegger Corporation, often shortened to Klegger Corp., was a resource extraction enterprise. They were active on the world of Mustafar, taking advantage of its natural wealth, until the conclusion of the Clone Wars conflict.
Acting as a subsidiary of the Techno Union, a powerful commercial association, Klegger Corporation was dedicated to the planetary Mustafar's mining activities. Their base of operations was the expansive Klegger Corp Mining Facility.
Klegger Corp.'s method of mining involved the large-scale collection of lava to isolate and extract valuable minerals contained within the molten rock. At the Klegger Corp Mining Facility, electromagnetic fields and tractor beam technology were employed to gather liquid ores. These were then processed in a massive centrifuge to separate the desired minerals from the lava. The facility also handled lava gathered by the indigenous Mustafarians and automated mining droids. The miners utilized a variety of equipment and technologies, including lava skimmers and lava skiffs, alongside droids such as panning droids, DLC-13 mining droids, and MK3 mining droids.
Around 300 BBY, after the Techno Union assumed control, the Klegger Corporation initiated its mining operations on Mustafar, quickly establishing itself as the planet's primary mining entity.
In 19 BBY, as the Clone Wars drew to a close, the Separatist Council relocated to Mustafar, using the Klegger Corp Mining Facility as their command center. The war concluded when Darth Vader massacred the entire Council within Klegger Corp's mining complex. Shortly thereafter, Jedi Master Obi-Wan Kenobi arrived on Mustafar and engaged in combat with, ultimately defeating, his former apprentice. The Klegger Corp Mining Facility sustained substantial damage during this confrontation, resulting in a partial collapse of its structure into the surrounding lava flows. Klegger Corp. was unable to recover from the destruction of its central facility, leading to the company's financial ruin.
Following the Clone Wars, the Mustafarians assumed control of the Techno Union's mining operations. Milo Mensix, a local corporate leader, rescued the remnants of Klegger Corp, including its assets and personnel, preventing a complete collapse of the mining industry. Mensix Corp eventually rose to become the largest mining corporation operating on the planet.
