A fiery volcanic world where lava was mined like a precious natural resource, Mustafar often served as a place to dispose of unwanted evidence, a quality which drew Black Sun to the planet. It also drew the Sith: it was on Mustafar that Darth Maul began his Sith training. Mustafar also served as the last capital of the Confederacy of Independent Systems, and was the site of the Separatists' downfall, an event that shaped galactic history. In a duel that followed, Darth Vader fought his former master, Obi-Wan Kenobi, and lost, as a result of which he was forced to wear dark armor for the rest of his life.
Mustafar was a very young and volatile world, torn apart by opposing gravitational forces of the gas giants Jestefad and Lefrani, with the former being the closer of the two. Astride thick-skinned lava fleas, the native Mustafarians leapt across the lava fields to mine the planet's unique and valuable minerals present in the lava.
The intense geological activity creates natural scanning interference that has kept prying eyes away from Mustafar for most of its history.
The Mustafarians oversaw the mining facilities constructed by the Techno Union on the planet.
Once a lush green world, Mustafar was home to a Jedi Enclave built around 5300 BBY. Jedi Master Chu-Gon Dar, an individual whose mastery of physical Force was unmatched, also lived there. He created a unique Force-sensitive object while on the planet known as the Chu-Gon Dar cube which was used to both channel and manipulate the physical Force to alter the physical properties of an item placed inside it. However, in 3996 BBY, the resurgent Sith wished to exterminate the Jedi, and so a climactic battle took place on the planet. This battle was so intense that one of the nearby gas giants was pulled into its current location by the Force, starting the gravitational tug-of-war. The environmental hazards caused by this forced the Jedi to abandon their temples on the planet. This caused all knowledge of Chu-Gon's cube to be lost. Mustafar would also be the home of the Force organization the Blackguard.
Mustafar was home to two variants of sentient Mustafarians—the northern Mustafarians, who were tall and thin, and the southern Mustafarians, who were short and squat. Centuries ago, a cataclysmic eruption destroyed all Mustafarian settlements except for Fralideja.
At the time of the Clone Wars, the Techno Union had owned Mustafar since c. 300 BBY, harvesting minerals and energy from the 800-degree-hot lava. It was comparatively cool compared to most other lava due to the unusual mineral allotropes that became molten at a lower temperature. Regardless, the lava could only safely be mined when a repulsor field was placed to repress any eruptions and deflect heat away from those harvesting it.
But the Techno Union wasn't the only corporate power interested in Mustafar. Before the Clone Wars started, Damask Holdings maintained a facility on the planet, in a structure previously owned by Boss Cabra, Vigo of Black Sun. There, the Nightbrother child who would become Darth Maul was trained by Darth Sidious so that he could serve the purpose of the Sith Lord and his secret Master, Darth Plagueis.
During the early years of the war, Supreme Chancellor Palpatine, in his guise as Darth Sidious, tasked the Duros bounty hunter Cad Bane with kidnapping Force-sensitive children and taking them to the Damask Holdings facility on the planet, where he could turn them into a cadre of Force–wielding spies for the Galactic Empire. The plot was scuttled by Anakin Skywalker and his Padawan, Ahsoka Tano.
At some point prior to the second year of the war, Black Sun, under the leadership of Xomit Grunseit, moved its headquarters to a fortress on Mustafar. Death Watch, together with their new allies Darth Maul and Savage Oppress, arrived in the Black Sun complex with an offer of allegiance. When Grunseit refused, Oppress murdered all the members of his cabal, making Captain of the Guard Ziton Moj leader of the syndicate.
The main Separatist stronghold was located in a massive industrial complex located on a fiery cliff bracketed by two huge lava flows. Collection arms mined lava from the area, while durable industrial droids worked further afield. Within this facility lay a Separatist command center, one of the most secure bunkers in the galaxy.
Toward the end of the Clone Wars, Palpatine would continue to have a vested interest in the planet, ordering General Grievous to move the Separatist Council there near the end of the war, apparently for their own safety, but in reality to gather them together so that Skywalker, newly anointed as Darth Vader, Palpatine's new apprentice, could kill them all, and deactivate the droid armies, bringing about the end of the war. Shortly afterwards, a duel between Obi-Wan Kenobi and Darth Vader would also take place on the lava planet. During the duel, the controls to the mining complex were destroyed and the repulsor fields dropped, allowing the violent lava eruptions to overwhelm the complex.
Vader suffered grievous injuries, including the loss of his remaining limbs, and the searing of his lungs, when he attempted to jump to higher ground from a platform on the lava river, only to be immobilized by Kenobi. He was later rescued by Emperor Palpatine, who brought him back to Coruscant, where he was rebuilt into the feared cyborg executor of the Emperor at the Emperor Palpatine Surgical Reconstruction Center. It was also on this planet, immediately prior to the Kenobi/Vader confrontation, that Lord Vader, who, unknown to Padmé Amidala, was no longer the man she had married, Force choked the pregnant Senator of Naboo into unconsciousness. This would eventually contribute to the causes of her death, alongside the loss of will she suffered, as well as her broken heart.
After the destruction of the Separatist Council and the Imperialization of the Techno Union, Mustafar was largely forgotten, until a Separatist stalwart, the fugitive Geonosian Gizor Dellso, holed up on Mustafar during the early days of the Galactic Empire and re-activated an independent battle droid factory, intending to rebuild the Confederacy's previous military strength.
From 18 BBY to 12 BBY, he constructed a small army and a flotilla of warships above the planet, and got the support of several fellow Geonosians. One year later, the situation had been required by the attention of the loyal 501st Legion of stormtroopers to storm the planet. At the battle's end, with the droid schematics destroyed and Dellso eliminated, the base was annihilated in a massive orbital strike from Imperial I-class Star Destroyers, which resulted in the fall of the Geonosian Industries, along with the fragmentation of the Separatist holdouts.
At some point, Mensix Corp established the Mensix Mining Facility, built to replace the previously destroyed Klegger Corp Mining Facility complex.
Galactic civil warEdit
Prior the time the Death Star plans were stolen, Twi'lek mercenary Rianna Saren and Zeeo were sent to gather Intel on current Imperial operations and sabotage the Mirkanite Mining Facility.
The mission was successful as the duo narrowly escaped from Imperial soldiers and a squadron of TIE fighters.
After the destruction of the first Death Star, it was rumored that several would-be Jedi found their way to the legendary world of Mustafar, and were apparently guided on their path to Knighthood by the spectral form of Obi-Wan Kenobi. A disturbance caused by a gathering of dark side energy drew Kenobi's spirit to the planet. Other explorers at the time apparently encountered the ancient assassin droid HK-47 along with an ancient Hammerhead-class cruiser, both having ended-up here back in the Cold War.
The Sith Lord X1, formerly a clone trooper, had made Mustafar his base of operations sometime during the New Republic era. X2 found his brother on Mustafar and led New Republic troops in a battle. After a fight over the planet, X2 and his troops descended to the planet's surface. X2 destroyed his brother's cloning lab, and the two brothers dueled, ending with the death of X1.
At sometime during 137 ABY, Mustafar came under the control of Darth Krayt's Galactic Empire.
