Sunspot Sunspot was a minor planet that was located within the Tython system of the galaxy ' s Deep Core region . The small world experienced violent storms when it passed the planet Malterra in its orbit , and it had an extremely hot climate . More than thirty - six thousand years before the Battle of Yavin , the non – Force - sensitive settlers of the planet Tython colonized Sunspot . Millennia later , mining operations had been established on the planet . Description . Sunspot was a minor planet with no moons that was located within the Tython system of the galaxy ' s Deep Core region . The orbit of the small world was closer to its sun , Tythos , than that of any other planetary body in the star system , coming as close as forty - eight million kilometers at some points . Additionally , Sunspot was near to the orbital path of Malterra , the second planet of the system . The two worlds rotated around their common star in opposite directions , however . Scientists speculated that Sunspot was a rogue planetoid that had been captured by the gravitational pull of Tythos . Sunspot experienced violent space storms and magnetic interference when it passed Malterra in its orbit for four days , and the climate on the small planet was extremely hot . A tectonically active world , Sunspot was considered solid but was a planet in constant flux . Volcanoes erupted constantly around the equator , and groundquakes racked the world every day . Despite the hostile environment of the planetoid , Sunspot ' s crust was filled with exotic elements that could be transformed into fuel , or converted into weaponry . Deeper down , strange crystals that rang with the power of the Force could be found . Scientists also speculated that the rare element known as dark matter could be found , or at least created using material buried in the arid environment . Settlements existed in the polar regions of the world , where the ground was more stable and habitable . Even from its dark side , the violent storms that racked the world were visible from space as the lava and magma illuminated the atmosphere ' s noxious clouds with a pinkish light . History . When the non – Force - sensitive settlers of Tython — the fifth planet of the system — traveled to its neighboring worlds more than a millennium after the year 36 , 453 BBY , they began to turn their thoughts to Sunspot . It wasn ' t until the 29 , 000s BBY that a series of exploratory missions began visiting the world to search for any signs of previous habitation . Believing the planetoid to have originated from outside the star system , the scholars examining the world believed that it might hold clues to its origins but were underwhelmed with the lack of evidence the crust held . The mining operations on Sunspot relied on a rotational crew of miners hoping to earn their fortunes , attracted by legends of great stores of wealth in the planet ' s crust . While 10 % of miners died every year , and a miner might only remain on the world for one or two seasons , the profitability of the mines was no mere myth . At some point before 25 , 800 BBY , the Koorivar Slug had an incident on the planet that left him indebted to Daegen Lok — a member of the mystic Je ' daii Order . By 25 , 793 BBY , mining operations had been established on Sunspot , which were made possible by the use of environment suits . In that year , Ketu — a Temple Master of the Je ' daii Order — told the Padawan learners Harun and Resi the history of the Tython system , and mentioned the colonization of Sunspot , amid other events . Stargazer plot . In the the final years of the Je ' daii Order , rogue Je ' daii Journeyer Dalien Brock led a cabal of Stargazers to Sunspot to arm a device designed to power a Gree hypergate they believed was hidden deep in the Old City of Tython . Tracked to Sunspot by Je ' daii Ranger Lanoree Brock and her comrade , Tre Sana , the rogue Je ' daii had planned his trip to Sunspot to coincide with the orbital crossing of the planet with its neighbor Malterra . Hoping that the space storms would prevent the Order from stopping his plot , Je ' daii Brock managed to land at Ran Dan ' s Folly near the southern pole safely . Hoping to prevent her brother from finding dark matter in the bowels of the abandoned mining complex , she failed to stop the Stargazer Cult but managed to continue after them to prevent them from succeeding on Tython . Behind the scenes . Sunspot was first pictured in the entry for Tython in The Holonet feature of the official website for " " — a 2011 massively multiplayer online roleplaying game developed by BioWare . The planet was depicted in a schematic of the Tython system . Since its establishment in 2008 , " The Old Republic " website has gone through a number of changes , resulting in the removal of some of the features and images that were originally located there , including the aforementioned schematic . The Tython system — and therefore Sunspot — was placed in grid square L - 10 by " The Essential Atlas " — a reference book co - authored by Jason Fry and Daniel Wallace , and published on August 18 , 2009 . Sunspot ' s name and additional information on it were provided in " " , a preview issue of the " " series of comic books . The issue was published on February 1 , 2012 , and was written by John Ostrander and penciled by Jan Duursema . The small world was also mentioned in the and the issue of the series , which were published on February 15 , 2012 and February 27 , 2013 , respectively .
