- "That's it, your highness... Metalorn! Just one in hundreds of Imperial factory planets."
- ―Rebel Captain
At one point, Metalorn was a sun-beaten forest world where, in the upper atmosphere, it was almost impossible for weaker ships to land because the intense heat would melt them. In the lower surface however, there was a lush tropical forest. The surface was a barren wasteland of rock, ash, and industrial magma pits created by underground city-factories. There was a gigantic wasteland that held large amounts of trash and junk.
Old Republic eraEdit
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 droids for the Confederacy of Independent Systems' army. Under the Techno Union, rivers 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.
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.
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.
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.
