Uphrades Uphrades was a planet located in the Uphrades system of the Inner Rim . Originally a green and fertile agriworld during the years leading up to the Galactic War between the Galactic Republic and the Sith Empire , Uphrades supplied the Republic capital planet of Coruscant with much of its food supplies . This earned it the nickname " Coruscant ' s Granary " until the Sith Lord Darth Angral targeted the agriworld during his campaign of vengeance in 3643 BBY . As part of his revenge against the Republic and the Jedi Order for the death of his son , Tarnis , Angral tested the Desolator superweapon on Uphrades and devastated its surface , killing millions and trapping the few hundred survivors on the planet by ionizing its atmosphere . Thanks to the efforts of Doctor Senessa and the crew of the Republic medical frigate " Daybreaker " , the survivors endured the several months it took for the ion field to dissipate , but the planet itself remained a desolate and barren world . Description . Located in the Uphrades system , a star system in the slice of the Inner Rim that lay between the Hydian Way and the Perlemian Trade Route hyperlane s , Uphrades was a green agriworld throughout much of its history . Located in the galactic region known as the Northern Dependencies , the terrestrial planet ' s soil was especially rich thanks to a significant amount of volcanic activity some 20 , 000 years before the Cold War between the Galactic Republic and the Sith Empire . Uphrades also possessed a temperate climate with a Type I atmosphere breathable for Humans and significant surface water separating its five continents . However , when the Sith Lord Darth Angral used the Desolator superweapon on the planet , Uphrades ' surface was torn apart , and its atmosphere turned into an enormous ion cannon . Large chunks of the planet ' s crust were ripped away , exposing pockets of magma and forming an asteroid belt around the world , while the missing pieces of the crust left behind craters . The planet ' s oceans were vaporized , and its green surface turned to ash , leaving behind rocky plains and canyons with rivers of lava . History . Approximately 1 , 500 years after the founding of the Republic , Uphrades experienced a large amount of volcanic activity that caused the world ' s soil to become especially rich over the next twenty millennia . The planet fell within the extent of space that the Galactic Republic had explored as of the beginning of the Great Manifest Period by the year 20 , 000 BBY , and the Uphrades system fell within the Republic ' s boundaries throughout the rest of the Republic ' s history until its reorganization into the Galactic Empire . By the end of the Great Galactic War with the Sith Empire , Uphrades was a fertile agriworld that supplied a large portion of the food for the Republic ' s capital planet of Coruscant . This earned it the nickname " Coruscant ' s Granary " by the time of the Cold War , when the Jedi Master Syo Bakarn and the Jedi Restoration Concord worked with the people of Uphrades to quadruple the planet ' s food production in just two years . Sometime between 3645 BBY and 3643 BBY , Jedi Master Bela Kiwiiks visited the planet with her new Padawan , Kira Carsen . However , Uphrades became a target of the Sith Lord Darth Angral during his crusade against the Republic in 3643 BBY . In an attempt to exact revenge on the Jedi Order and the Republic for the death of his son , Tarnis , at the hands of a Jedi Knight , Angral brought the Desolator superweapon to bear on Uphrades . Constructed using stolen Republic weapons technologies , the Desolator ionized Uphrades ' atmosphere , trapping all 16 million inhabitants on the world before destabilizing the planet ' s core through seismic vibrations . The attack devastated Uphrades ' surface , killing millions and leaving only a few hundred survivors on the planet . The Republic medical frigate " Daybreaker " was in the Uphrades system when Angral ' s warship , the dreadnought " Oppressor " , arrived and attacked the planet , and wreckage from Uphrades ' surface damaged the " Daybreaker " . An Imperial boarding party subsequently attacked the disabled frigate , but a Jedi Knight — Tarnis ' s killer and the target of Angral ' s wrath — arrived just in time to stop the assault . After the attack , the " Daybreaker " medical officer , Doctor Senessa , detected survivors on the surface , and she decided to take the frigate down to deliver aid . The ship ' s captain , a Cathar named Dal , objected when he learned that the " Daybreaker " would be disabled and unable to leave the planet if they entered the atmosphere and decided to take an escape pod rather than sacrifice himself for the survivors . With the supplies aboard the " Daybreaker " , Senessa and the ship ' s crew ensured that those on the surface survived the several months that it took for the atmosphere ' s ionization to dissipate . Once Republic aid ships were able to enter the atmosphere safely , the survivors and the " Daybreaker " crew were rescued . Inhabitants . In the days before Angral ' s attack , Uphrades boasted a population of 16 million farmers and food technologists , spread out across Uphrades ' five continents . However , the catastrophic effects of the Desolator killed almost all of those 16 million people , leaving less than a thousand survivors . Behind the scenes . Uphrades first appears in the massively multiplayer online roleplaying game " " , released by BioWare and LucasArts on December 20 , 2011 . The planet appears in the finale of the Act I storyline for the Jedi Knight class , after the player completes the assignments on the planets Tatooine and Alderaan . While its exact location is uncertain , Uphrades ' placement on the in - game map and the Galaxy Map on " The Old Republic " official website corresponds to grid square M - 8 in the Inner Rim , near Mindor in the region of space between the Hydian Way and the Perlemian Trade Route . The devastation of Uphrades and the attack on the " Daybreaker " appear in the Jedi Knight mission " Uphrades " and feature one major alignment choice . Captain Dal presents a dark - side option when he asks the Knight to convince Doctor Senessa that the sensor readings showing signs of life on Uphrades are false and that there are no survivors , as Dal wants to return to his family . As a reward , the captain offers to bribe the player with medical supplies from the " Daybreaker " stock . The light - side option of refusing his offer results in Dal taking an escape pod while Senessa and the crew of the " Daybreaker " travel down to the surface , despite knowing that they will be unable to leave . Senessa will later send a message of thanks to the player , confirming that the people on the surface will be able to survive until the atmosphere becomes safe again and the Republic can launch rescue efforts .
