Concordia / Legends Concordia was one of two moons orbiting the Outer Rim world of Mandalore . A verdant moon possessing dense forests , the Mandalorians originally settled Concordia as an agricultural colony . However , during the time of war , the Mandalorians established a vast number of mining camps on the moon in search of " beskar " iron , a nearly indestructible metal ore unique to Mandalore and its orbiting satellite . The excessive strip - mining operation almost destroyed Concordia ' s forests , though by 22 BBY , they were making a recovery . Centuries after the rise of the pacifistic New Mandalorian faction , the violent renegade sect of Mandalorians known as the Death Watch incited numerous Mandalorian clan leaders to war against their peaceful regime in a conflict that became known as the Great Clan Wars . The Death Watch - backed warlords were eventually defeated , reluctantly accepting exile to Concordia , an independent Mandalorian province the rule of which was turned over to Clan Vizsla . By the beginning of the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems , Concordia was governed by Pre Vizsla , a public supporter of New Mandalorian leader Duchess Satine Kryze , but secretly the leader of a reborn faction of Death Watch . Vizsla established a Death Watch base in the moon ' s abandoned mines , where he worked in secret to rebuild the Death Watch . His base was discovered by Jedi Master Obi - Wan Kenobi during an investigation of the Death Watch ' s presence in current Mandalorian affairs , and his efforts to turn the New Mandalorians against the Republic were thwarted by the combined actions of Kenobi and Duchess Kryze . With Vizsla ' s ties to Death Watch were exposed to all , he lost his position as governor of Concordia , and was eventually forced to abandon the Mandalorian moon to join Death Watch in a nomadic existence wandering the galaxy , until he led a coup against the New Mandalorians to take power . Description . Concordia was a terrestrial moon , one of two satellites that orbited the planet Mandalore , the cultural homeworld of the Mandalorian people , located in the Mandalore sector of the galaxy ' s Outer Rim Territories . One of several habitable locations in the Mandalore system , Concordia was a lush , temperate moon , with chains of mountains dotting its surface . As the system ' s sun set , Concordia could be seen from the surface of Mandalore as a green sphere in the evening sky . A verdant moon where dense forests grew , Concordia became an agricultural colony after being settled by the Mandalorians . The Mandalorian moon was home to a number of animals , including carnivorous predators who were known to chance attacking sentient prey at night . Individuals who ventured out into the Concordian plains in the dark could ward off the moon ' s predators with fire . During the period when Mandalore continued to engage in large - scale warfare , Concordia became the target of " beskar " iron miners , who scoured the moon for the nearly indestructible metal . Unsightly mines marred much of Concordia ' s surface , almost destroying the moon ' s forests in the process . Even after the Mandalorians ' wars came to an end , it was only around the time of the Clone Wars that the Concordian forests began to make a recovery . The old mines were abandoned to fall into disrepair , a symbol of the mining industry left behind , only be revitalized by the radical Death Watch splinter sect to serve as hidden bases for their operations on Concordia and a place to manufacture armor and munitions in secret . History . The early Mandalorian Taung conquered the uninhabited world that would become Mandalore around 7000 BBY , naming the world for their leader , Mandalore the First . As they set out to capture the surrounding worlds of the Mandalore system , the Mandalorians eventually turned their sights on the lush and forested moon of Concordia . Over time , the verdant moon became an agricultural settlement , inhabited and tended by Mandalorian farmers . During the Galactic War , the Mandalorian soldier Galron made camp on Concordia with his twin daughters Mari and Tayn . Around the fire , they spoke of the famed warrior Shae Vizla and the ancient Mandalore the Conqueror , before the girls drifted off to sleep under their father ' s watchful eye . Eventually , interest in Concordia turned away from agriculture and in the direction of mining . As the Mandalorians continued to wage war centuries prior to rise of the Galactic Empire , they sought " beskar " iron ore from beneath the surface of Concordia . The metal was a galactic rarity , found only on Mandalore and its moon , and was prized for its nigh invulnerability , capable of withstanding the blows of a lightsaber . Ugly mines came to scar the surface of Concordia , and the Mandalorians ' strip - mining efforts were so extensive that the moon ' s native forests were nearly destroyed . Following the Mandalorian Excision — a brief but overwhelming conflict between the Mandalorians and the Galactic Republic that transformed portions of Mandalore into barren deserts of white sand — a reformist political faction of Mandalorians was born : the New Mandalorians . The New Mandalorians believed in pacifism , and sought to establish a peaceful society isolated from the traditional warrior clans . Rogue elements within the warrior clans worked to see the New Mandalorians ' downfall for centuries , eventually culminating with the foundation of the Death Watch splinter group under Tor Vizsla around 60 BBY . In an attempt to see the New Mandalorians ' downfall , Death Watch incited a number of clan chieftains to war against the pacifists , though other clan leaders rose to defend them . In the end , the Great Clan Wars resulted in a defeat for Death Watch , and the beaten but unrepentant clan warlords accepted exile to Concordia . Control of the Mandalorian moon was turned over to Clan Vizsla , to act as a province independent of the New Mandalorian state . By the start of the Clone Wars in 22 BBY , more than a decade after the end of the Great Clan Wars , it was the position of the New Mandalorian government that the warriors that had been exiled to Concordia had died since out . During this time , Concordia was ruled by Governor Pre Vizsla , an outward supporter of the New Mandalorians and friend to their leader , Duchess Satine Kryze . In secret , however , Vizsla was the leader of the Death Watch , rebuilding the sect in the wake of the Great Clan Wars . Vizsla established a base of operations in the abandoned " beskar " mines of Concordia , using the facilities to manufacture Mandalorian armor and armament , and as a staging ground for his Death Watch forces . Vizsla ' s plans and the Death Watch ' s secret base were uncovered by Jedi Master Obi - Wan Kenobi and Duchess Kryze during a visit to Concordia in the early months of the Clone Wars . Discovered , Vizsla fought Kenobi to a draw , and a trio of his Death Watch troops forced the Jedi Master to retreat with the Duchess back to Mandalore . Even still , Vizsla continued to use Concordia and his base there as a staging ground for a planned Death Watch takeover of Mandalore . There , he amassed an army of soldiers , but before an attack could be made , Count Dooku — Vizsla ' s ally in the Confederacy of Independent Systems — ordered his men to stand down due to the veto of a Republic defense initiative that would have sent a contingent of clone troopers to Mandalore . Vizsla and Dooku had planned to use the Republic occupation to sway the Mandalorian populace to support Death Watch as would - be liberators against an oppressive offworld force . Without the backing of Mandalore ' s people , Death Watch did not have the strength to take control of the planet . Death Watch was later driven from Concordia and the surrounding Mandalore system , eventually establishing a camp on the far away world of Carlac . By the Clone Wars ' end , Concordia had acquired a reputation for doing business with a number of pirates and smugglers that operated in and around Mandalorian space . Areas of the moon were known to host an ostensible presence of the Black Sun crime syndicate , operating under the oversight of Vigo Xizor ' s lieutenant , Tyno Fabris . Non - Mandalorian offworlders with business on the Mandalorian homeworld would occasionally make planetfall on Concordia to fulfill their needs , rather than journeying down to the surface of Mandalore itself . Inhabitants . Concordia was first inhabited by members of the Mandalorian culture as an agricultural settlement , becoming a home to a number of Mandalorian farmers . Later , the moon was transformed into a mining base , and Concordia became a haven for " beskar " miners , operating the numerous mines littered across the moon ' s surface . The people of Concordia were collectively known as Concordians , and spoke a dialect of " Mando ' a " — the traditional Mandalorian language — also known as Concordian , a dialect shared by the nearby world of Concord Dawn . In the aftermath of the Great Clan Wars , several unrepentant warrior clan chieftains who had sided with Death Watch to dethrone the New Mandalorians went into exile on Concordia upon their defeat . The rule of the Mandalorian moon was entrusted to the members of Clan Vizsla , and by the time of the Clone Wars , Concordia was recognized as an independent province , separate from the New Mandalorian state and ruled by its own governor . Behind the scenes . The moon of Concordia was first introduced to the " Star Wars " universe in the twelfth episode of the , entitled " The Mandalore Plot . " The Mandalorian moon made subsequent appearances in the following episodes " Voyage of Temptation " and " Duchess of Mandalore , " before receiving a mention in the episode " Shades of Reason . " The novels " " and " The Last Jedi " made additional mentions of Concordia , as did the young reader book " " , and the " " web short " Bedtime on Concordia . " Although " The Essential Atlas " — a galactic geography reference book author ed by Jason Fry and Daniel Wallace , and published August 18 , 2009 — was the first source to state Mandalore was orbited by two moons , Concordia was the first to be introduced by name . Fry ' s later sourcebooks " " and " " featured additional information on the Concordian moon , and " The Essential Guide to Warfare " Fry co - wrote with Paul R . Urquhart gave further mention and information of Concordia .
