Mount Corvast Mount Corvast was a volcanic mountain , and capital of the planet Sarapin . Situated amidst a series of islands , it was a mineral - rich location filled with abundant natural resources . It was also the center of operations for the planet - wide energy mining facilities , and was also the only known established city on the planet . It provided power to the majority of the Core Worlds . During the Clone Wars , it became the key point of contention during the Hunt for the Decimator . Jedi General Jor Drakas was sent by the Galactic Republic to defend the vital location , but his forces were defeated by the Dark Acolyte General Sev ' rance Tann . Tann instated Zian Finnis as the caretaker of both the city and the planet while she continued fighting across the galaxy , but the Confederate occupation did not last long . General Echuu Shen - Jon reclaimed the city shortly after Tann ' s attack , restoring power to the Core Worlds . Description . Bordered on at least one side by a river of lava , Mount Corvast was pockmarked with deposits of natural resources . Surrounding it was a series of small islands amid the cobweb of lava streams . It was ringed with smaller ranges of carbon reserves which were constantly harvested to provide for the settlement . To a lesser extent , there were both nova crystal and ore deposits . However , there were no known food resources on the mountain , although banthas were known to reside in the vicinity . In order to make the location suitable for settlement , metal plates were arranged across the top of the lava pool at the peak of the mountain , creating an artificial plateau . Gaps were left in the plates , possibly for cooling purposes . The largest structure on the plateau was the Mount Corvast Citadel , the center of operations for the planet - wide mining facilities . With the advent of the Clone Wars , however , the Republic installed fortresses , defensive turrets , factories , and research centers . The city was also walled , although whether the wall was installed for defensive purposes during the Clone Wars , or existed prior , is unknown . After the outbreak of the Clone Wars , Sev ' rance Tann ' s forces took the volcanic capital , and much of the Republic architecture and infrastructure was destroyed in the process . It was quickly replaced by Geonosian defensive structures , the construction of which was overseen by Zian Finnis . These defensive structures , in turn , were swept away by the troops of General Echuu Shen - Jon . The slopes of Corvast were supposedly difficult to traverse , a problem likely encountered by both Republic and Confederacy forces when they scaled the mountain in 22 BBY . There was at least one bridge that led to the mountain , and at least one track that was usually well - covered by the defender ' s turrets , making an assault difficult . Most of the mountain was surrounded by sheer cliff faces , making beaten tracks the only ones worth considering for transit . The surface at the base was also highly unstable , and lava often burst through to the surface , due to pressure build - ups . History . Early history . At an undetermined time , settlers established a city atop the volcanic mountain of Mount Corvast . Built above the pool of lava at the summit , it became both the capital city of Sarapin and the headquarters for the mining facilities across the planet . In addition to the location serving as a perfect vantage point for observing mining operations , the plethora of carbon deposits that ringed the city provided a rich stream of natural resources . Clone Wars . In the first few months of the galaxy - wide Clone Wars , Republic High Command suspected that the Confederacy of Independent Systems might try to secure Sarapin ' s natural energy reserves , providing them with a cheap source of power . Such an occurrence would also cause an enduring blackout on many critical Core Worlds ; so , naturally , High Command sought to fortify it . Jedi General Jor Drakas was dispatched to the volcanic world , where he established a base at Mount Corvast . Not only could he keep a watchful eye on the mining process so as to deter any sabotage attempt , but it was a perfect vantage point , should the Confederacy invade . He also had an orbital defense grid put in place , should they try to bombard Corvast from space . First Battle of Sarapin . General Sev ' rance Tann — an acolyte of the Confederacy Head of State — was dispatched to Sarapin to claim the world for the Confederacy . Utilizing the new Decimator technology , her troops fought through the orbital grid and landed in the vicinity of Corvast . Drakas watched as Tann ' s forces plowed through his defenses , battering aside the clone troopers dispatched to halt her advance . During her ascension to the pinnacle of Mount Corvast , her troops destroyed many of the laser drills lining the road , permanently damaging the intricate mining operation . Tann ' s forces eventually made it to the top of the mountain and into the city , but to the Chiss general ' s surprise , Drakas had kept his best troops in reserve . His heavy turrets rained down upon the Confederacy troops , who fought back with the extremely powerful Decimators . When the battle reached its peak , both generals entered the fray , golden lightsabers flashing and carving their way through opposing troops . Nevertheless , Tann ' s forces were able to overcome the Republic ' s defenses , obliterating the turrets and wiping out the troops . Drakas perished in the chaos , though whether it was by Tann ' s hand or by some other means is not known . Confederacy forces swept into the Mount Corvast Citadel , damaging it heavily , and Tann knocked out the power supplies of approximately eighty percent of the Core worlds . Zian Finnis was brought in to oversee the repairs to the Mount Corvast defenses , and to make sure the Confederacy was reaping the benefits of Sarapin . Second Battle of Sarapin . Unfortunately for the Confederacy , the Republic response was swift . The Jedi Council dispatched General Echuu Shen - Jon and his new Padawan , Naat Reath , to reclaim the energy planet for the Republic . Finnis had barely even been given the opportunity to install his own Geonosian - based defensive structures , and had certainly not begun repairs to the existing Corvast buildings that had been heavily damaged during Tann ' s attack . Due to this , Shen - Jon ' s advance was far easier than Tann ' s , and he was able to successfully reclaim Mount Corvast , restoring power to the Core worlds . Inhabitants . Sarapin did not have any known native sentient species , but Mount Corvast was inhabited by Humans and other employees once the mining system was installed . With the advent of the Clone Wars , a substantial garrison of clone troopers lived in the barracks set up within the city walls . When Zian Finnis took control of the city , it was home to a small defensive force of droids and Geonosian builders . Locations . Mount Corvast Citadel . The largest structure in Mount Corvast was the Mount Corvast citadel , the center of operations for the planet wide mining operation . Located in the center of the city , the building was almost razed by Sev ' rance Tann during her conquest of the world , but was presumably restored by the Republic when Echuu Shen - Jon reclaimed it . Mount Corvast Spaceport . Mount Corvast was home to a small spaceport that was the transport hub of the planet . It is possible that this structure was razed by Sev ' rance Tann during her attack on the mountain . At any rate , the Confederacy did not install their own spaceport upon occupation . Republic defenses . During the Clone Wars , the Republic installed a variety of defenses to ward off attacking forces . These included at least two fortresses and several turrets , both anti - infantry and anti - air . A series of factories and training facilities were also installed along the outskirts of the city . Behind the scenes . Mount Corvast first appeared in the LucasArts expansion pack to " " , " " . It was also mentioned in passing in Daniel Wallace ' s " The New Essential Chronology " .
