Castell / Legends Castell was a terrestrial planet located along the Perlemian Trade Route in the Colonies region of the galaxy . The homeworld of the Gossam , Castell was a major foundry planet for the Commerce Guild . History . A terrestrial world located along the Perlemian Trade Route , the Gossam homeworld was reached by other sentient species during the blazing of that route between 30 , 000 BBY and 25 , 000 BBY . Having begun experimentation with the tumble hyperdrive during the Infinite Empire ' s reign over parts of the galaxy , the Gossam Courivers were able to leave Castell and colonize planets such as Felucia circa 27 , 000 BBY . When the Galactic Republic was born out of the Core Worlds , Castell joined the rapidly expanding government sometime before 22 , 000 BBY . Involvement in galactic history was rare for Castell , remaining within Republic space even during times of conflict . During the Great Sith War , the Krath waged a Holy Crusade along the worlds of the Perlemian in their attempt to conquer Coruscant . Recovering from the war , the Republic would race along the Perlemian and its worlds during the Jedi Civil War to engage the armies of Revan ' s Sith Empire . During the latter half of the Republic ' s Golden Age Castell fell into a decades - long depression , only to find an ally in the Commerce Guild . Upon the Guild ' s intervention , the war and slaughter brought about by starvation and economic crisis ended abruptly as the Guild swept in and funneled money into the economy by buying much of the world . In exchange , many Gossams worked as indentured servants for a portion of their life in order to maintain ownership of their property . One such Gossam was the young , corporate - minded Shu Mai , who rose through the corporate world to become Chief of Property Resources . As Mai became more and more prolific in her career , she managed to repurchase the entire planet from the Commerce Guild and lead her people to prosper . In return for her work , Mai raised rents on the world and demanded that her people give her tribute in thanks for gaining back the planet ' s independence from the Guild . True independence never came , however , as Mai was named Presidente of the Commerce Guild and Castell remained one of its largest powerhouses . Mai would eventually lead her people away from the Republic during the Separatist Crisis , pledging the Commerce Guild ' s clandestine funding in exchange for a place on the governing Council of the Confederacy of Independent Systems . While creating an elite group of Gossam Commandos , Mai and the other Separatists incited the Clone Wars , a bloody war of separatism , against the Republic . As Castell was surrounded by Republic space , the region was patrolled by the 3rd Sector Army of the Grand Army of the Republic . Eventually Castell itself fell to Republic forces , much to Presidente Mai ' s dismay . Retreating to Felucia and denounced by her people , Mai was reassured by her superior , Count Dooku that the loss of her homeworld was all apart of his master plan . In 19 BBY , following Presidente Mai ' s execution along with the rest of the Separatist Council on Mustafar by Darth Vader , the war ended and the Galactic Empire arose from the ashes of the Republic . Because of their former allegiances , the Gossams of Castell were targeted by the Empire for enslavement , and the factories of the world were repurposed to manufacture military goods for the Imperial Navy . Undoing any of the meager good that Shu Mai and the Commerce Guild had managed to achieve , Castell spiraled back into economic turmoil under the Empire and was unable to supply many soldiers to the fledgling Rebel Alliance , though many expressed support for the group . When the Rebel Alliance eventually emerged victorious over the Empire , it took a year for the New Republic to move down the Perlemian , liberating Castell in 5 ABY . Struggling to recover despite their newfound independence , the world suffered greater setbacks during the Yuuzhan Vong invasion of the galaxy . Conquering Castell , the world was ravaged by the invaders until the New Republic forced itself down the Perlemian once again , from Dac to Coruscant . With the rise of the Galactic Alliance , Castell once more began the recovery process . As of 137 ABY , Castell fell within the area controlled by the Empire of Darth Krayt .
