Metalorn / Legends Metalorn was an industrial world in the Talcene sector of the Mid Rim , between Anzat and Roche . Once a hot jungle planet , its rich veins of ore attracted heavy industry , and by the time of the Clone Wars Metalorn had become a polluted factory world covered with industrial plants , mines and ore refineries . Metalorn was one of the Confederacy of Independent System ' s most productive industrial planets during the Clone Wars , and under the Galactic Empire became a penal colony for dissidents . The planet was occupied during the Yuuzhan Vong War and was heavily Vongformed , reversing many centuries of pollution and turning it into a prime recruiting ground for the Peace Brigade . Description . At one point , Metalorn was a sun - beaten jungle world where , in the upper atmosphere , it was almost impossible for weaker ships to land because the intense heat would melt them . At the surface however , there were lush tropical forests separated by shallow seas . Metalorn ' s rich veins of ore attracted heavy industry in the decades before the Clone Wars , in particular Baktoid and the Techno Union . Metalorn was remade as a factory world covered in plants , refineries and ore - processing centers making everything from security droids for the Trade Federation to industrial goods for the Core and Colonies . The surface became a barren wasteland of rock , ash , and industrial magma pits created by underground city - factories , the rainforests withered and burned , and the planet ' s shallow seas became irreversibly polluted . A large area of the planet was dominated by a gigantic refuse pile known as the Wasteland , which held large amounts of trash and junk . Among the only native species that survived industrialization were the chitin - armored daggerflies , which fed on the vermin that infested the factory refuse heaps . History . Old Republic era . Techno Union foreman Wat Tambor built a factory on Metalorn which manufactured B1 battle droids for the Techno Union ' s security forces , and later C - B3 cortosis battle droid s for the Confederacy of Independent Systems ' army . Under the Techno Union , river s were converted into canyons so they could move the materials to the factories more easily . During the Clone Wars , the planet was part of the Foundry of the Confederacy , a swath of industrial planets loyal to the Confederacy of Independent Systems , supplying it with weapons and warships . Because of that it was a constant target of attacks by the Galactic Republic and changed hands several times during the war . Later on Anakin Skywalker foiled the creation of the cortosis droids and captured Wat Tambor on Metalorn in 21 BBY . In 19 BBY , the Techno Union captured Jedi Master Shaak Ti and were holding her in a high security prison , which no one had ever escaped from . After finding out about this , senator Bail Prestor Organa of Alderaan came up with a desperate mission to save the imprisoned Jedi by convincing Wat Tambor that Alderaan wanted to join the Confederacy of Independent Systems and convert Alderaan into a factory world like Metalorn . Tambor was deceived and allowed Organa to land the " Tantive IV " on Metalorn so that he could give the Alderaanian a tour of the factories . During the tour Bail asked to see the Techno Union ' s prison facilities . Tambor brought the group to Unreal City , the prison complex of Metalorn that was so big it could hold twice the population of a normal planet and was visible from orbit . While touring the complex , Bail was able to locate Shaak Ti ' s holding cell and free her using her lightsaber . During the battle that ensued , they were then able to escape in the " Tantive IV " and leave the planet for good , saying that they had to notify the Galactic Republic and the Jedi High Council about the atrocities that were going on on Metalorn . Later history . Soon after the Declaration of a New Order , a campaign was fought when the Galactic Empire attempted to drive out the holdout forces of the CIS led by ex - Senator Toonbuck Toora from the region of the " Foundry of the Confederacy " . At Metalorn , the Separatists were defeated by the Imperial 12th Sector Army , under the command of Admiral Adar Tallon and General Jan Dodonna . Under the New Order , Metalorn was a primary industrial world of the Galactic Empire under Governor Corwyth . Human laborers wore identical uniforms and were allowed to do little other than work . They were little more than slaves . In 0 ABY , Leia Organa infiltrated the world and planted the seed of Rebellion in the heart of a young native girl named Tammia Hollusen . Tammi rebelled against the oppressive Empire by planting a single flower on Metalorn . After the Battle of Endor in 4 ABY , Metalorn was integrated into the Greater Maldrood , an Imperial faction established by High Admiral Treuten Teradoc . It was later freed by the New Republic . Metalorn was conquered and vongformed by the invaders during the Yuuzhan Vong War . The planet thus became a recruiting place for the Peace Brigade . After the war , former Peace Brigadier Tammia Hollusen became Metalorn ’ s leader . In 32 ABY , Leia Organa Solo returned on the planet to discuss a truce with Hollusen .
