Nyriaan / Legends Nyriaan was a planet that was located in the Luire system , in the Mid Rim . Description . Nyriaan was rich in madilon , a rare , naturally occurring alloy that could be used to make hyperdrives smaller . It was a habitable world , with an atmosphere that was made up mainly of nitrogen and oxygen , and a mean temperature of 40 °C . The planet was covered by a thick , cloud layer , that blocked communications and made unaided landing almost impossible . Large storms were common and could last for months at a time . They posed a constant threat to settlements , so they were monitored by the Tempest Observation Bureau . The planet surface consisted of plains and low hills , with some valleys , where boggy conditions had formed . In the northern hemisphere , there were many shallow , rocky valleys , which were where most of the planet ' s mining operations took place . An interesting feature of Nyriaan was the effect that its atmosphere had on the Force . While Force - users could use the Force when on the planet surface , they couldn ’ t while traveling though the planetary atmosphere , due to an unidentified interference . Flora and Fauna . Hundreds of thousands of different animal species evolved on Nyriaan and the majority of them were small in stature . One of the few larger species were the lluma , which were herbivorous herd animals . Another species were the omnivorous , frog - like pherin s . Both species were preyed upon by Nyriaan ’ s top predator , the chlovi cat . Nyriaan also had a vast number of different plant species , including many different species of fungi , although only 5 % of the planet ' s plant species had been classified by scientists . One of the more common species was the chlovi , a type of large fungus . Other species included the deadly Falsin ' s rot and the massive Meadlin ' s tree s , which were the largest species of fungi on Nyriaan . Another plant , a small fungal weed , called the mire nettle , could be processed to create Nyriaan spice , a type of powerful narcotic . The parasitic fungus tempest ' s blessing grew on and lived in symbiosis with host organisms and could increase the host ' s visual acuity . History . Discovery and exploration . The Luire system was discovered in 4129 BBY and in 4067 BBY , the exploration ship " Starveil " carried out an extensive study of the system . However , it crash landed on Nyriaan . During the Jedi Civil War , the Sith Lord Darth Glovoc had a vison that there was something of interest on Nyriaan . He took command of the " Interdictor " - class cruiser " Dying Sun " and he traveled with it to the Luire system . However , while the cruiser surveyed Nyriaan , it was attacked by three Republic cruisers . The " Sun " destroyed the cruisers , but was critically damaged and became caught in the planet ' s gravity well , eventually crash landing on Nyriaan . Escape pods from all four ships also landed on the planet ' s surface . In 403 BBY , the Corporate Sector Authority ship " Commerce " went missing while attempting an orbital scan of Nyriaan . More CSA ships were sent to explore the planet , they made no significant discoveries and heard nothing from the " Commerce " . Two Republic - funded vessels , the " Locus " and the " Ardent Virtue " arrived in the Luire system in 90 BBY , to carry out a five - year survey . In 87 BBY , the " Locus " lost power while scanning the atmosphere of Nyriaan and made a controlled landing on the planet . The " Virtue " attempted a rescue , but failed in it ' s initial attempts , losing two shuttles in the process . The following year , with additional Republic support , the crew of the " Ardent Virtue " constructed a gondola , that was tied to the " Virtue " and lowered onto the surface of Nyriaan . The wreckage of the " Locus " was located by the landing party , but they found no sign of the surviving crew members . They then proceeded to carry out a preliminary surveys of the planet from the ground , and also established laser comm array s , so that they could directly communicate with the " Virtue " . In 85 BBY , the crew of the " Ardent Venture " discovered traces of madilon in the soil of Nyriaan . They attempted to keep this secret , but a CSA research station on the nearby planet Caillte intercepted communications and learned of the discovery . Some of the " Venture " ' s crew members attempted to sell the information for personal profit , causing a number of survey ships to travel to the Luire system . Many of them made unsuccessful attempts at landing on Nyriaan . Settlement . The CSA wanted possession of Nyriaan and its madilon deposits , so in 84 BBY the CSA laid claim to the entire Luire system . The Republic rebuffed their claim and for the duration of the resulting legal battle , a quarantine of Nyriaan was enforced . In 81 BBY , a Republic court ruled that the CSA only had jurisdiction over Caillte , not the Nyriaan and the rest of the Luire system . Nyriaan was opened for settlement and a number of new settlements were established , utilising an updated version of the gondola system . The Tapani sector noble houses House Mecetti and House Reena both established settlements of their own . The first laser transport arrays were established on Nyriaan by the CSA in 69 BBY , allowing properly equipped starships to land on the planet . The specific details on how to user laser array technology were leaked two years later , allowing anyone to acquire the technology and land on the surface of Nyriaan . In 66 BBY , the Hyperspace Navigator ' s Guild began to press the Galactic Senate to pass legislation to require bonded navigators to assist with all laser transport array landings on Nyriaan . The CSA protested , but the Senate passed the legislation anyway . Following the CSA - sponsored liquidation of a settlement , in 47 BBY , the Nyriaanan natives staged an uprising and wiped out a number of frontier towns . In 43 BBY , with the assistance of the Jedi Knight Amar Cros , a non - aggression pact was negotiated , restoring peace to the planet . Due to the influence of the Trade Federation , in 39 BBY the Mining Guild attempted to drive up prices on Nyriaan . The CSA attempted to undermine the Guild , so the Guild responded by sabotaging the CSA ' s ore transfer facilities . In 36 BBY , the CSA prospected on land owned by the native Nyriaanans , in breech of a mining agreement . The natives initiated hostilities against the CSA and the Trade Federation and Mining Guild secretly gave support to the insurgency . The Galactic Senate acted to resolve the tensions on Nyriaan once and for all , by passing the Luire Accord . The planet was divided up into a number of regions , each controlled by a different group , while a government , the Nyriaan Concord , was established . A number of reservations were set aside for environmental purposes and the native clans retreated into the planet ' s unexplored regions . The CSA began a large - scale immigration of laborers to Nyriaan in 29 BBY . The majority of the laborers were Pa ' lowicks and by the end of the year , every major settlement on Nyriaan had a Pa ' lowick ghetto . A number of Pa ' lowicks freed themselves from bondage to the CSA and established the settlement New Lowick . The Clone Wars . An inter - galactic conflict known as the Clone Wars broke out in 22 BBY , between the Republic and the Confederacy of Independent Systems . The Confederacy captured Nyriaan during the First Battle of Nyriaan and the Republic ' s holdings on the world were annexed and split between the CSA and the Mining Guild . Without the restrictions that had been placed on them by the Republic , the CSA and the Mining Guild both expanded their operations and began exploiting native land . The natives resisted violently , and were assisted by the remnants of the Republic forces . In 19 BBY , a Republic strike force was dispatched to the Luire system and the CIS was defeated in the Second Battle of Nyriaan and driven from the system . However , shortly afterwards , Supreme Chancellor Palpatine , the leader of the Republic , initiated Order 66 and all of the Jedi in the system were killed . Imperial rule . Following the end of the Clone Wars , the Republic was re - organized to become the Galactic Empire , which became the new ruler of Nyriaan . In 17 BBY , House Melantha of the Tapani sector staked a claim on Nyriaan . The Empire began the construction of a large ion shield ing station in 13 BBY , located just outside Locus , the planetary capital . The station was completed in 8 BBY and was capable of projecting energy shields , to protect starships from the hazards of Nyriaan ’ s atmosphere . This allowed the Empire and the Mining Guild to initiate Operation Cloudfall , the stripping of all of the planet ’ s useful ore . The shield station was sabotaged by agents of the Alliance to Restore the Republic in 1 BBY , bringing it offline for three months . By 2 ABY , an Alliance - affiliated insurgency had stopped Operation Cloudfall . The majority of the operation ' s slave Wookiee and Mon Calamari workers then joined the insurgency . The New Republic and the Yuuzhan Vong . Following the fall of the Empire , in 8 ABY , the New Republic offered to recognize Nyriaan ’ s planetary autonomy , as governed by the Nyriaanan natives . The madilon exporters rallied against the offer and although the native clans were intrigued by it , the exporters were successful . In 10 ABY , the CSA launched a legal challenge against the New Republic ’ s right to offer Nyriaan independence . The resulting court battle was lengthy and was never fully resolved . In 26 ABY , the Yuuzhan Vong , a species of extra - galactic invaders , conquered Nyriaan . Their attack was made easier by the fact that their technology was unaffected by the Nyriaanan atmosphere , and they destroyed all of the mining operations . The Yuuzhan Vong priests proclaimed that the planet was blessed , because of the way its atmosphere resisted the Force . The Vong originally ignored the native clans , but when they began using captured natives for experiments , the natives initiated a guerrilla war , to try and drive the invaders out . Following the defeat of the Vong in 29 ABY , a number of Yuuzhan Vong refugees settled on Nyriaan and were eventually accepted as equals by the native clans . The Galactic Alliance began reconstruction efforts on Nyriaan in 31 ABY and Locus was rebuilt , while the Imperial shielding station was repaired . The CSA resumed mining operations in 38 ABY , after rebuilding their old facilities . Nyriaan later fell under the control of the Fel Empire and its successor government , Darth Krayt ' s Galactic Empire . Some Sith agents heard rumors about the " Dying Sun " , so in 132 ABY , the Sith Lord Darth Vurik was sent to Nyriaan , to investigate . Inhabitants . Nyriaan was home to a number of Nyriaanan native clans , who were descended from the human crew of the " Starveil " and other starships that had crashed on the planet over the years . They had evolved to become adapted to the planet , with pale skin , a stocky stature and eyes that were well suited to the world ’ s dim light . They spoke Nyriaanan , a mixture of Basic and High Galactic . The natives were distrustful of the colonists and prospectors who lived on Nyriaan , seeing them as competition for the planet ’ s resources . Some of the clans were nomadic , while others lived in the groves of Meadlin ' s trees , The planet was also home to the Children of the Tempest , the descendants of the Sith crew of the " Dying Sun " . Over time , they had became twisted and inbred , but retained their devotion to their leader , Darth Glovoc . They only constituted a small part of Nyriaan ' s population and generally remained in seclusion , but on occasion , would encounter the Nyriaanan clans , whom they would attack on sight .
