Mygeeto / Legends Mygeeto was a wealthy InterGalactic Banking Clan colony between Ord Biniir and Morishim under control of the Confederacy of Independent Systems . Geographic features . Since Mygeeto was locked in an ice age , giant crystallized glaciation and ice covered its surface , as well as huge crystal spurs . Because of this , Mygeeto meant " gem " in the ancient trade language of the Muuns . Mygeeto ' s internal fires long since cooled and had left a colossal deposit of precious stones within its crust and mantle . The immense assets of nova crystals and fields of lasing crystals made Mygeeto one of the wealthiest worlds in the galaxy . It hosted artesian crystal s and relacite . The planet ' s ice shelves were home to a species of huge and aggressive worm - like creatures . In addition , the planet itself was enveloped by an asteroid field . Mygeeto was not composed of a uniform terrain ; instead it was composed of many different kinds of terrain . There was no reported volcanic activity on the planet , meaning that the planet ' s interior was stable . The immense amount of precious metals found in the crust supports the theory that Mygeeto ' s volcanic activities had been dormant for some time . Few cities existed on Mygeeto ' s sunken surface . These cities drew power from synthesized crystals which were constructed in large capacitor towers that stored and distributed the valuable energy drawn from the crystal . These cities were used mainly for administering the surrounding crystal mines , though they also contained vaults which were used by the InterGalactic Banking Clan . Nearly all of the planet ' s surface was covered in thick ice , and the polar climate caused massive snow storms that battered the frigid surface almost continuously . Before the giant ice age , Mygeeto had a climate ranging form polar to temperate — 30 % of Mygeeto was covered in polar ice caps and 70 was either tundra or temperate . Temperature varied between - 47 degrees in polar areas to 17 degrees in equatorial areas . Every 200 years or so , Mygeeto would go through a snow shift meaning snowfall would be persistent and low pressure would dominate the northern hemisphere . This would also mean Mygeeto ' s mean temperature would dip , significantly affecting the whole planet . History . Pre - Republic . The sentient lemur - like Lurmens were indigenous to Mygeeto in times long forgotten during the Pre - Republic era . Around 30 , 000 BBY , an alien species known as the Rakata annexed Mygeeto as part of their Infinite Empire . The Lurmen were forced by the Rakata to shape Mygeeto ' s crystal formations , but with the break - up of their empire after five thousand years of galactic dominance the Rakata abandoned Mygeeto and retreated to their homeworld of Lehon . Dark Age . By 6740 BBY , the planet was rediscovered by smugglers , with Hutts and then Neimoidians taking control of the planet in the following years . InterGalactic Banking Clan . When the Muun controlled InterGalactic Banking Clan discovered Mygeeto , the native Lurmens were reduced to a status little better than slaves . Due to easily mined formations of naturally - occurring , high - quality crystals and jagged rocks present on the planet , the InterGalactic Banking Clan guarded Mygeeto with a fleet of warships including " Munificent " - class star frigates . As a result , access by rivals to the planet was difficult . Even if intruders had bypassed the blockade , they were faced with the harsh , frozen surface of the planet itself . The Jedi had always wanted to explore the planet because of the large supply of natural crystals suitable for lightsaber construction , but the Banking Clan would not allow it . The Banking Clan also constructed several cities on Mygeeto . These cities were used for administering the surrounding crystal mines , though they also contained vaults which were used by the Banking Clan to store its treasures . Mygeeto had even become the sister world of the Muuns ' own homeworld , Muunilinst . During the Banking Clan ’ s rule of Mygeeto , the planet was administered by Caar Damask . The Dark Lord of the Sith Darth Tenebrous , under the guise of starship designer Rugess Nome , brought Caar and a Force - sensitive female Muun together . Their son Hego Damask was born on Mygeeto and would go on to become the Sith lord Darth Plagueis , who would later return to the planet with his apprentice Palpatine at the beginning of his training . Caar owned a residence here on Mygeeto which is where Plagueis grew up . Clone Wars . During the Clone Wars , Mygeeto became a valuable member of the Confederacy of Independent Systems and was as a result named by Supreme Chancellor Palpatine as part of a " Triad of Evil " , alongside Felucia and Saleucami . Later , General Ki - Adi - Mundi led the Republic assault on the world along with Commander Bacara and the elite Galactic Marines . The planet would be the site of many horrific battles during the Clone Wars , beginning in 21 BBY . By the conclusion of the battle in 19 BBY , the vast cityscape lay in burning , ash - filled ruins . The hot ashes mixed with Mygeeto ' s ice crystals to cover the battlegrounds in sleet and snow . Many Republic vehicles , including UT - ATs , were blown apart by Confederate tri - droids . Later , Ki - Adi - Mundi ' s forces were reinforced by troopers from the 501st Legion sent by Palpatine himself . Officially , the 501st Legion had been sent to destroy a droid energy collector , but in reality they were searching for an experimental power source that Palpatine required for a top - secret tributary laser - stream project code - named Hammertong to power the Death Star . Clone Troopers destroyed two turbo laser turrets so that Ki - Adi - Mundi could land . After landing , Ki - Adi - Mundi led an assault on the energy collector , securing the power source that Palpatine had been looking for . Finally , he sent the power source offplanet to Coruscant , and aided the Republic troops in battle . Towards the end of the conflict , Commander Bacara received Order 66 and killed the Jedi General . Following the assassination , the remaining pockets of droids were eliminated , thus ending the two year - long battle and the Confederacy ' s presence on Mygeeto . Galactic Empire . After Mundi ' s death and the resolution of the Clone Wars , the newly established Galactic Empire enslaved the planet , claiming it on behalf of Palpatine , who had now taken on the title of Emperor . The Imperial war - machine would keep strict control in the turbulent times following the Clone Wars ; they extensively strip - mined the planet for a mineral known as durasteel , used in the construction of starship hulls . However , unlike other factions of the CIS , the Empire would not destroy the IGBC , as it would doom the galaxy to a crippling recession , but rather subjugated the government . Galactic Civil War and after . During the Galactic Civil War , Mygeeto fell into the hands of the Alliance to Restore the Republic . Darth Vader led a contingent of TIE / LN starfighter s to the planet to put down the uprising . After the Battle of Endor in 4 ABY , Mygeeto had become a member of the Alliance of Free Planets and subsequently the New Republic . However sometime later during the war , Mygeeto was conquered by the Imperial Remnant . By 25 ABY , however , Mygeeto lay within the New Republic ' s boundaries . It was subsequently attacked by the Yuuzhan Vong during their war with the New Republic , but was not devastated like Muunilinst . When the Second Galactic Civil War broke out in 40 ABY , Mygeeto had remained an Imperial Remnant world , and had become a financial center of that entity . This trend continued with the Fel Empire and the Empire - in - exile but ended with the Galactic Federation Triumvirate .
