Iridonia / Legends Iridonia was the homeworld of the Zabrak species . Due to the harsh living conditions , the Zabrak were a hardy species . They took to flight and then space travel as soon as they could develop the technology , and by the time the Duros encountered them , they had already colonized five systems . Notable Iridonians included Agen Kolar , Bao - Dur , Drell Kahmf , Sirak , and Maris Brood . History . Wars of the Sith and Mandalorians . As a Mid Rim world situated near important hyperspace lanes , Iridonia was one of the key worlds that connected the Inner Rim to the Outer Rim . As such , it was often one of the first planets to be pulled into a war . When Iridonia increased taxes on imported technology from Duro , Duro ' s officials banned their shipments to Iridonia in retaliation for the tariffs . The Zabrak leaders did not want their populace to know that they would make a deal with the Duros government , so an under - the - table negotiation was planned at a neutral location : Cloud City over the gas giant Bespin . The Duros representative , Belai Kaleeg , was shot , but survived , and his assailant was killed . When he later met with the Iridonian representative , Koon Odan , and was looking over the treaty documents , the documents went blank and Odan tried to run away . It was revealed that the Iridonian government had sent an assassin to kill Kaleeg to stop the treaty . After the plot was revealed , the documents were restored and the Iridonia government denied all involvement . If Odan was killed after the treaty documents went blank , the treaty between Iridonia and Duros was canceled . The disagreements escalated , and a small - scale war between the two planets broke out , and had to be settled by outside entities . During the Old Sith Wars , the planet was the site of numerous battles . A battle at Iridonia , fought during the Great Sith War , was a major victory for the Galactic Republic . It was a turning point in the war which gave the Republic Military and the Jedi Order momentum which would help them to eventually defeat their Sith adversaries . Several of Iridonia ' s colonies along the Outer Rim were conquered by the Mandalorians during the initial stages of the Mandalorian Wars . After learning of the loss of their colonies , many Iridonians , including Bao - Dur , sought revenge by joining the Republic ' s war effort against the Mandalorian invaders . In the same year , 3963 BBY , the Mandalorian Neo - Crusaders launched a major offensive against Iridonia . After a successful campaign , they occupied the planet for a number of months , but Iridonia was eventually liberated by the Republic Military . Iridonia changed hands a number of times during the Jedi Civil War . The Sith Empire and the Republic fought fiercely over the planet , and both sides used it as a staging ground during the conflict . Due to the fact that Iridonia was occupied by the Sith at times , the eight Iridonian colonies became self sufficient . Following the war , they broke away and became independent worlds . Around 1002 BBY , the Brotherhood of Darkness operated a Sith academy on the world that trained Sith Acolyte s and apprentices . The Sith also hired Zabrak mercenaries from the planet ' s high council . Post - Ruusan history . After the Ruusan campaign , the Zabrak established colonies on many far - flung worlds . The Zabrak of Iridonia maintained the most militant culture , and Zabrak youths from the colonies were often sent to the original homeworld for warrior training . During the Clone Wars , Iridonia and its colonies remained loyal to the Republic . Several months after the First Battle of Geonosis , and after the Confederacy of Independent Systems tried to cause political upheaval and insurrections in the colonies , one of Iridonia ' s eight colonies petitioned to secede from the Republic . This caused " The Great Debate , " but ended with Iridonia and all of its colonies continued support of the Republic . The New Republic and beyond . Kaysil Verwood became the first New Republic senator of her people , representing not only Iridonia but all the Zabrak colonies . The Zabrak were founding members of the government , as Verwood attended the Galactic Caucus to form the new government . At some point after the formation of the New Republic , Luke Skywalker visited the world as an ambassador to help with opening new trade routes to the Outer Rim Territories . While staying on the planet , he encountered a solid - state hologram said to be the ghost of the Dathomirian Zabrak Sith Lord , Darth Maul . The ghostly image had terrified the Zabrak government for some time , driving one council representative to the brink of madness . Skywalker tracked the apparition down to a laboratory run by the Zabrak scientist Drell Kahmf , who claimed to have salvaged the brain of Maul and constructed the hologram body for it to wreak havoc on society . The Jedi was appalled at the torment of the disembodied man , and disconnected the device keeping the brain alive . When Darth Krayt ' s Galactic Empire was first established , Iridonia was amongst the first world to pledge its allegiance to the new Emperor . Since Zabraks were traditionally a species that produced many Force - sensitives , Iridonia contributed more apprentices to the One Sith than any other world . However , despite the wishes of Iridonian government , several Zabrak colonies rebelled against the new Empire . Two such colonies were completely wiped out when " Pellaeon " - class Star Destroyers issued Base Delta Zero to reduce their planets to rubble . After the punishment the remaining five colonies surrendered to Imperial forces and one of them , Feldrona , was transformed into a prison planet and placed under tight Imperial control .
