Skytop Station / Legends Skytop Station was a Confederate listening post during the Clone Wars . A modified core ship , the station was designed to monitor Republic communications , thereby providing the Confederate Droid Army with vital intelligence on the movement of enemy fleets . Skytop Station was built and crewed by the Hyper - Communications Cartel , a business group formed by Confederate leader Po Nudo . It was stationed in the upper atmosphere of one of the moons of Ruusan . Once construction was completed , Skytop Station began to intercept Republic HoloNet transmissions , providing the Confederacy with intelligence on the movement of Republic fleets . Following the Battle of Bothawui , High Jedi General Obi - Wan Kenobi tasked Jedi General Anakin Skywalker and his Padawan , Jedi Commander Ahsoka Tano , with finding and destroying the station . The two discovered Skytop Station ' s location after receiving a distress call from the captured Republic droid R2 - D2 , who was being taken to the station to be delivered to the Confederate General Grievous . Skywalker and Tano traveled to the station and infiltrated it alongside members of the Grand Army of the Republic ' s 501st Legion with the intent to rescue R2 - D2 and destroy the listening post . Despite Grievous ' s efforts to thwart the Republic forces , Skywalker and his companions were able to disable Skytop Station ' s reactor and repulsorlift generators , causing the core ship to fall from the sky . Description . Originally a Trade Federation core ship , Skytop Station was heavily modified by the time it was utilized as a listening post . Unlike a standard core ship , the station possessed large antennae protruding from both the top and bottom of the vessel . Additionally , massive sensor dishes crowned the station ' s upper hemisphere . Its interception range spanned the entire galaxy , being able to eavesdrop on HoloNet messages as well as monitor long - range movements of starships . Internally , the station contained a disassembly chamber for the dismantling of droids , as well as landing bays that possessed enough space to accommodate Vulture droid starfighters and " Rogue " - class starfighters . The doors to the landing bays were controlled by astromech droid interface terminals , both within the bays and on the exterior of the station . Skytop Station also had at least one room filled with battle droid components for storage . Aqualish technicians monitored the information collected by Skytop Station in darkened rooms near the disassembly chamber . The station was kept afloat by repulsorlift generators that were powered by reactors ; the reactors themselves were protected by a ray shielded door . Skytop Station ' s complement of Vulture droid starfighters and " Rogue " - class starfighters provided more than adequate defense for the facility . When General Grievous took command of the listening post , he added B2 super battle droids and IG - 100 MagnaGuards to its defenses . B1 battle droids also helped to maintain the station . History . Confederate service . Skytop Station was brought online in 22 BBY in the upper atmosphere of the moon Ruusan 2 after the Separatist organization known as the Hyper - Communications Cartel completed extensive modifications to its original core ship frame . The moon was chosen as the ideal location for the spy station , as it possessed an electrically - charged atmosphere that disrupted scanner s and prevented the detection of objects within it . Shortly after the station was fully activated , the Confederate Head of State , Count Dooku , traveled to it alongside his Dark Acolyte apprentice , Asajj Ventress . Dooku and Ventress were given a tour of the new station by Cartel leader Po Nudo , who proclaimed that Skytop Station would be capable of picking up countless Republic transmissions throughout the quadrant . Although Ventress detested the principals of covert eavesdropping that were embodied in the listening post , Dooku was impressed with the station . The technicians at Skytop Station later intercepted a communication between Supreme Chancellor Palpatine of the Republic and King Katuunko of Toydaria . The two discussed a possible alliance between the Republic and Toydaria , and planned for negotiations to take place on Rugosa . With this information , Dooku was able to dispatch Ventress to Rugosa in order to make an offer of alliance to Katuunko on behalf of the Confederacy . The station later came under the command of the Confederate General Grievous , who used the intercepted transmissions in order to ambush Republic fleets . Shortly after the Battle of Bothawui — during which Jedi General Anakin Skywalker lost his astromech droid , R2 - D2 — Republic Intelligence was able to confirm that a Confederate listening post was the source of the ambushes . High Jedi General Obi - Wan Kenobi charged Skywalker and his Padawan , Jedi Commander Ahsoka Tano , with locating the station and destroying it . During a scouting mission in an area of suspected Confederate - held space , Skywalker was attacked by two Confederate frigates after his location was revealed by the Confederate spy droid R3 - S6 , who was serving as Skywalker ' s astromech droid after the loss of R2 - D2 . R2 - D2 had in fact been captured by the Trandoshan scavenger Gha Nachkt after the conflict at Bothawui , and the scavenger had arranged for the Republic droid to be sold to General Grievous . Nachkt traveled to Skytop Station in his ship , the " Vulture ' s Claw " , to deliver R2 - D2 and collect his fee . En route to Skytop Station , R2 - D2 was able to alert Skywalker to his position by connecting to the " Vulture ' s Claw " communication system . Skywalker , who had been rescued from the Confederate frigates by Tano and Clone Captain CT - 7567 , was still searching for both Skytop Station and his astromech droid . He followed R2 - D2 ' s signal to the Hoth ' s Brand system where the listening post was located . Destruction . After the " Vulture ' s Claw " landed on Skytop Station , Nachkt led R2 - D2 to a room filled with surveillance posts manned by Aqualish technicians . There , Nachkt met with Grievous , who demanded that R2 - D2 be taken to the disassembly chamber to be dismantled and searched for information . While Nachkt dissected the astromech , Skywalker , Tano , and a contingent of clone troopers from the Grand Army of the Republic ' s 501st Legion arrived above Ruusan in their ship , the " Twilight " , and followed R2 - D2 ' s signal into the upper atmosphere of one of the planet ' s three moons . The group , along with R3 - S6 , free fell from the " Twilight " onto the station , where Skywalker used his lightsaber to cut an opening in the station ' s roof . The Republic forces entered Skytop Station and split up ; Skywalker searched for R2 - D2 , while Tano and the clones set off to plant explosives in the station ' s reactors . In the disassembly chamber , Nachkt was able to crack R2 - D2 ' s memory banks , revealing that the droid had never had its mission memory erased . The Trandoshan expected extra payment for the discovery ; however , Grievous opted to kill him and simply forgo payment . The general was then informed by his spy , R3 - S6 , that Republic forces had infiltrated the station . Grievous put Skytop Station on high alert and ordered several IG - 100 MagnaGuards to move the dismantled R2 unit to his ship while he confronted the intruders himself . The alert status triggered a ray - shielded security door to be lowered over the entrance to the reactor room , preventing Tano and the clones from planting the explosives . R3 - S6 appeared to be attempting to lower the shield ; in actuality , the droid was stalling until battle droids arrived to combat the Republic forces . Although Clone Captain CT - 7567 , nicknamed Rex , was able to disable the droids , all but two of the clones were killed by Grievous when he arrived . In order to save Rex and Denal , the two surviving clones , Tano engaged Grievous and led him into a storage room filled with spare battle droid parts . Elsewhere within the station , Skywalker caught up with the MagnaGuards that were escorting R2 - D2 to Grievous ' s ship . Skywalker defeated the droids , and together with R2 - D2 , he escaped to the south landing bay , where he contacted the " Twilight " for an immediate evacuation from the station . Meanwhile , Rex and Denal completed the mission ' s primary objective and planted explosives within the reactor room before rendezvousing with Skywalker in the landing bay . As Skywalker attempted to leave the bay to locate Tano , R3 - S6 , who had been sent by Grievous to delay the Republic forces , sealed all exits from the bay and activated several Vulture droids that had been hanging from ceiling - mounted recharge racks . The droids opened fire , forcing Skywalker and the clones to take cover near several docked " Rogue " - class starfighters , while R2 - D2 attempted to open the hangar bay doors from an external control port on a maintenance catwalk . As the fight in the hangar continued , Skywalker ordered Captain Rex to activate the explosives , despite the fact that the Republic squad was still in the station . Rex complied , and the resulting explosion crippled the repulsorlift generators and shook the entire structure as flames erupted from Skytop Station ' s lower hemisphere . Tano , who had been captured by Grievous , used the explosion as a distraction and escaped by entering one of Skytop Station ' s air ducts . She joined the Republic forces in the hangar bay while Grievous fled the doomed battlesphere in his starship , " Soulless One " . As Skytop Station plummeted from the upper atmosphere of the Ruusan moon , R2 - D2 was able to open the hangar doors for the south docking bay , allowing Tano , Rex , Denal , Skywalker , and their clone pilot to escape the station in the " Twilight " . Skywalker briefly returned to the crumbling station in his starfighter to rescue R2 - D2 from the external maintenance catwalk , shortly before Skytop Station met its end . Commanders and crew . As a Confederate listening post , Skytop Station was heavily staffed and protected by droids . Several different models of battle droids served as guards aboard the battlesphere , and it was noted that the 631 model B1 battle droid s that served aboard the station were less intelligent than other droid models . The droids also suffered from servomotor corrosion as a result of the atmospheric moisture on the Ruusan moon . The station ' s extensive sensor systems were monitored and controlled by Aqualish technicians . At some point during the war , the station was placed under the command of General Grievous , the Supreme Commander of the Droid Armies . Utilizing the information gathered by the station for surprise attacks , Grievous was able to repeatedly ambush Republic forces . However , Skytop Station was destroyed while under the command of the cyborg general . This , in conjunction with Grievous ' s loss of the " Malevolence " , greatly shook Count Dooku ' s faith in the general . Behind the scenes . Skytop Station was designed and created for the 2008 . The station first appeared in the " " , and was referenced to in the series ' episode " Downfall of a Droid . " It finally made its series debut in the following episode , " Duel of the Droids , " where it served as both the episode ' s setting and a major plot point . From a production standpoint , the station ' s interior actually consists of one primary hallway , re - shot from several different angles to give the appearance of multiple hallways within an immense structure . Aside from the corridors , " The Clone Wars " design team only had to create two new sets — the supply room and the hangar . The station also appeared in the Nintendo DS version of the 2009 video game " " ; however , this appearance introduced numerous continuity errors in Skytop Station ' s history . In the game , General Grievous is not in command of the station during the Republic ' s assault , which is performed by Skywalker , Tano , Rex , and Denal . When Skywalker and Tano reach Sector AA - 23 of the station , all of its systems are shut down , including the repulsorlifts . The systems are reactivated shortly afterward when Rex and Denal turn them on via a control panel . The two are then able to destroy Skytop Station ' s reactor ; however this triggers a fail - safe lockdown , sealing the clones and Jedi within the crippled station . In order to open the hangar doors and escape aboard the " Twilight " , R2 - D2 and Tano deactivate a control terminal in the station ' s hangar while Skywalker deactivates one on the station ' s exterior hull . Skywalker , Tano , R2 , Rex , and Denal all return to the " Twilight " and make it off Skytop Station . In this version of events , the station is protected by regular battle droids , in addition to BX - series droid commandos and IG - 86 sentinel droids .
