Roon / Legends Roon was a planet located in the nearly impenetrable Cloak of the Sith . Known for its Roonstone s , the planet was constantly sought after by treasure hunters for years . Location . Located in an impenetrable cosmic dust cloud ominously referred to as the Cloak of the Sith , easily navigable routes to Roon had long been lost . Even the most complete accounts , located in the Baobab Archives on Manda , were sketchy at best , and the lockdown of information following the rise of the Galactic Empire seemed to seal Roon ' s fate as a planet lost to history . This was fine to native Roonians ; the planet was largely self - sufficient and plentiful in resources . Surrounded by a lethal ring of asteroids and meteors , Roon was located in an Outer Rim Territories system of the same name . Other notable planets in the Roon system included the searing rock planet of Kaloo ( which was moonless ) and the barren rock world Iqoon ( which had two moons ) . Like nearby Ryloth , Roon only rotated on its axis once every orbit around the sun , rendering one side constantly bright and the other side constantly dark . Unlike Ryloth , however , the lit side of the world was not scorching , nor was the dark side frigid ; this phenomenon may be due to cloud cover , or an extensive ozone layer . Whatever the reason , Roon long served as a staging point for spice smugglers coming from Ryloth . The way to Roon was rediscovered by explorer and treasure - hunter Mungo Baobab . In a move typical of his derring - do , Baobab followed the mysterious annual rainbow comet , a phenomenon that led him successfully through the Cloak of the Sith and near enough so that liberated prisoner Noop Yeldarb could guide him the remainder of the way . This became the Baobab Merchant Fleet - established Manda - Roon Merchant Route , a replacement for the near - suicidal , Twi ' lek - charted Death Wind Corridor connected to Ryloth . History . After being driven off of Coruscant , the Taung s fled to Roon , where they resided until 7000 BBY . At this point , they immigrated to the planet that came to be known as Mandalore . Ancestors of Roon ' s current inhabitants arrived on - planet near the end of the New Sith Wars , when the Brotherhood of Darkness made its headquarters there . During the prosperous years of the Old Republic , the world had a small but consistent trade with independent interests , importing necessary technologies and exporting flame jewel s , Roon spice , and the occasional Roonstone s . Some time between 42 and 32 BBY , Mahwi Lihnn took a bounty on Roon . Roon remained withdrawn from the New Order until 15 years before the Battle of Yavin , when Koong , governor of the Tawntoom province , contacted Admiral Terrinald Screed . Together , the two officials formed a loose and informal alliance to locate the cache of precious Roonstones . One of these Roonstones , which fell into the hands of Mungo Baobab , contained the text of the the legendary poem , " Dha Werda Verda " , which chronicled an ancient Coruscanti battle between the Taung and the Zhell . It was after Screed ' s interest in Roon that the planet finally began to become drawn into galactic affairs once more . A handful of Rebel groups managed to operate in the system , working with the natives of the Umboo province , a part of the planet known to have long opposed outside authority . It was through great efforts that Governor Koong tried again and again to subjugate this hardy people , but never to any avail . This was largely due to the efforts of Baobab , whose exploits on the world not only led to the discovery of the hidden Roonstone mines , but also to their subsequent destruction at the hands of the governor . Largely thanks to its isolation , Roon remained untouched by the Yuuzhan Vong War . Inhabitants . Roon had a temperate climate and standard gravity , making it a comfortable place to live for many species . Over the years , settlers of various species arrived on Roon ' s surface . Mostly the descendants of stranded smugglers and pirates , Roonians developed into a people who refused to discard archaic technologies if those techniques still worked . Thus , the resultant eclectic society placed starships alongside animal - driven labor and wooden boats . The planet ' s proximity to Ryloth resulted in a large Twi ' lek population . Some of the population , who worked in the wet fields , were known as " the mudmen of Roon . " Their name was occasionally invoked throughout the galaxy when one felt dirty . Fauna . Like its people , the animals of Roon all seemed to be transplanted from other corners of the galaxy . Notable among these introduced species were :
