Mission to Vassek ' s third moon Jedi Master Kit Fisto , Jedi Knight Nahdar Vebb , and a squad of clone troopers undertook a mission in 22 BBY during the Clone Wars to recapture Trade Federation Viceroy Nute Gunray , who had recently escaped from Republic custody . However , Confederate Head of State Count Dooku , displeased with General Grievous ' s recent failures in the war , used a Republic homing beacon to lure the Jedi and clones to the general ' s castle on the third moon of Vassek as a test for Grievous . Gunray deceived the Jedi and troopers through a holotransmission , and once they uncovered the ploy , Dooku contacted the Republic agents and put them on the trail of the " alternative prize " of Grievous . The Jedi and their troops set a trap for Grievous and confronted the cyborg general once he arrived . However , Grievous was able to eliminate several clone troopers , and after sustaining injuries , escape to the castle ' s secret command center . Sealing off the exits , the Confederate general trapped the Jedi and clones inside his castle . While Grievous was repaired by his caretaker droid , the general pitted the Jedi and the remaining clones against the castle ' s defenses — a molten incinerator pit and the general ' s pet roggwart , Gor . The clones were killed , but the Jedi were able to eliminate Gor . As Grievous resolved to personally confront the Jedi , Fisto and Vebb infiltrated the castle ' s command center . Vebb remained outside , however , and fought Grievous himself , but was killed by the general . After Fisto dueled Grievous on the castle ' s outer platform , the Jedi Master was able to escape . Prelude . In 22 BBY during the Clone Wars , Trade Federation Viceroy Nute Gunray — who had been captured by Republic forces on Rodia — was to be transferred aboard the Star Destroyer " Tranquility " to Coruscant for trial . The viceroy was kept under heavy guard by Jedi Master Luminara Unduli and Padawan Ahsoka Tano ; however , Gunray was able to escape with the help of Dark Acolyte Asajj Ventress and turncoat Senate Commando Captain Faro Argyus . The Confederate agents stole a Republic frigate to make their getaway , and the ship ' s homing beacon allowed the Republic to track the stolen cruiser . Since Jedi General Kit Fisto and his fleet were near Gunray ' s last known position , Unduli contacted the Nautolan Jedi Master to follow and recapture Gunray . Meanwhile , the Confederate Head of State , Count Dooku , had become displeased with the ongoing stalemate in the war between his best general , Grievous , and the Republic and Jedi Order . Grievous had failed in several recent operations , resulting in Confederate defeats at the Battle of the Kaliida Nebula and the Battle of Bothawui , as well as the loss of the listening post Skytop Station . As Dooku ' s Sith Master , Darth Sidious , demanded more dead Jedi , Dooku decided to arrange a trap for Grievous in order to reassess the cyborg ' s abilities . The Sith Lord remotely deactivated the general ' s personal IG - 100 MagnaGuard bodyguards in his castle on the third moon of Vassek and deployed the Republic tracking beacon from Gunray ' s stolen ship to the general ' s lair , seeking to lure the Jedi to the castle so that Grievous would be able to hunt them for sport . The mission . Bait for the Jedi . Fisto took his Delta - 7B starfighter and his astromech droid , R6 - H5 , and followed the signal of the Republic beacon to the Vassek system , deep in Confederate - held space . The Jedi Master contacted Unduli and Tano at the Outer Rim Command Center , and they reported that Fisto ' s former Padawan , Nahdar Vebb , had also tracked the beacon to the system . Vebb had already arrived on Vassek ' s third moon — where the beacon had been located — with a shuttle and several clone troopers . Fisto detached his starfighter from its hyperspace docking ring , and proceeded to the moon to rendezvous with Vebb . Once Fisto had landed and left R6 - H5 to look after his fighter , the Jedi Master met with Vebb . Clone Commander Fil had tracked the beacon to the south end of the gorge , and , leaving troopers Bel and Niner to guard the shuttle , the group proceeded to the castle . While Vebb and Fil intended to use lightsabers and thermal detonators , respectively , to forcefully open the entrance to the building , Fisto was able to find a secret switch that activated a mechanism that opened the castle ' s door . Approaching the sanctum overlook chamber of the castle , the Jedi and clones overheard a hologram of Gunray giving orders to a squad of B1 battle droids , led by a Lieutenant , from behind a high - backed chair . Unaware that Gunray was not actually present , Fisto and Vebb led the attack on the droids and were able to eliminate their opponents . However , when Vebb turned the chair around with the Force , the group discovered Gunray ' s hologram , and the viceroy taunted the Jedi before severing the connection . Count Dooku contacted the Jedi and directed them toward an " alternative prize " to compensate for their failed attempt to recapture Gunray . The Jedi were uncertain of who their offered quarry was , and Vebb activated a mechanism through the chair that revealed another hallway . As the Jedi and clones walked through the castle , rooms opened along the way ; inside the rooms were statues of Kaleesh warrior s — some featuring cybernetics — that resembled Grievous himself . The group finally entered Grievous ' s secret armory and workshop , and deduced that the castle belonged to the general . While inspecting Grievous ' s trophy room , home to a collection of trophies from the Jedi that the general had murdered , Fisto received a report from Bel and Niner that Grievous ' s personal starfighter , " Soulless One " , was approaching the castle . Fisto ordered the two clones protecting the shuttle to keep out of sight , while the Republic infiltrators decided to capture Grievous in an attempt to satisfy the " dead or alive " warrant on the Confederate general . Capturing a cyborg . As Grievous entered his castle , the Jedi and clones appeared and surrounded the cyborg general . Grievous activated two of his stolen Jedi lightsabers , and engaged Fisto and Vebb in combat . However , as the two Jedi saberlocked with the general , Grievous split his arms and activated two more of his lightsabers . The two Jedi were forced to break the bladelock as they avoided being slashed by the extra weapons , and Fisto ordered the clones to fire their blaster rifles ' cables at Grievous . The clones aimed their grappling hooks at the general ' s legs , and as Grievous engaged the Jedi in another saberlock , Fisto used his lightsaber to sever the cyborg ' s legs . Although crippled , Grievous was able to jump up and hold onto one of the beams attached to the roof . The clones ' grappling hooks were still attached to the general , and the troops were able to pull Grievous to the ground . As Vebb crossed blades with the cyborg , the lightsaber that Grievous was holding spun out of his hand . The general jumped back up , and one of the clones holding the grappling hooks was thrown backward , while the other was pulled toward Grievous . The general batted the dead clone against Fisto , forcing the Jedi Master backward , before throwing the trooper on top of Vebb . Grievous ' s faceplate was damaged from one of the clones ' laser shots , and as the general escaped , Vebb and several of the troopers gave pursuit . However , Grievous killed two more of the clones before entering the castle ' s secret command center ; of the clone troopers , only Fil and another trooper remained alive . The Confederate general discovered from his personal caretaker droid , EV - A4 - D , that his IG - 100 MagnaGuards had been remotely turned off for recharge . Grievous reactivated his droid bodyguards and ordered them to lock down the perimeter . As Fisto , Vebb , and the clones headed to escape from the castle , the general sealed off the building ' s exits , trapping the Jedi and clones inside his lair . Commander Fil contacted Niner and Bel back with the shuttle and ordered the two clones to signal the Republic outpost at Bestine that they required reinforcements . However , as Niner and Bel entered the shuttle , Grievous ' s MagnaGuards fired a rocket at the craft , causing the shuttle to explode . The droids closed in on R6 - H5 and Fisto ' s fighter , and the astromech droid escaped with the Jedi starfighter , spinning the ship and throwing off a MagnaGuard clinging to the fighter ' s hull . Hunted . Grievous opened a hololink and contacted the Jedi and clones , encouraging them to " experience all his home had to offer , " before severing the connection . The general then opened up a molten incinerator pit , and while Fisto and Vebb were able to jump to safer ground , the two clones fell into the pit . Fil fired a grappling hook to the ceiling , and the Jedi were able to rescue him , but the other trooper plunged into the incinerator . Fisto then destroyed a holocam that Grievous was using to watch his opponents , and the Confederate general signaled his ravenous pet roggwart , Gor , to " entertain their guests . " EV - A4 - D began to repair Grievous from the injuries he had sustained . As the Jedi and the clone trooper grouped together in the middle of a hallway junction , Gor appeared and approached the group . Fil opened fire on the roggwart , but Fisto ' s lightsaber was knocked out of his hand . Gor lunged at Fil and the two Jedi and the three quickly split up , surrounding the creature while Fisto retrieved his weapon . The clone commander directed blaster fire at Gor ' s neck and Vebb jumped onto the roggwart , plunging his lightsaber into Gor ' s back until he was bucked off . The roggwart swung its tail and seized Fil , batting Vebb with the captured clone . Fisto slashed the roggwart in the head , and Fil was slammed against the ground before Vebb severed Gor ' s tail . The Jedi Master cut off the roggwart ' s arms , and as Gor fell to the ground , Fisto killed the roggwart by driving his lightsaber into the back of the creature ' s neck . Vebb was shaken by Fil ' s death , but left the fallen clone and followed Fisto to the castle ' s command center . A repaired Grievous was angered upon learning of Gor ' s death , and the general soon discovered from Count Dooku that the Sith Lord himself had set the trap for him as a test . Resolving to personally eliminate the Jedi , Grievous left the command center with three MagnaGuards , despite EV - A4 - D ' s admonition that he required rest . As Grievous started to head away , Fisto and Vebb sneaked up to the entrance to the command center and the Jedi Master tried to figure out the secret mechanism that opened the door . However , EV - A4 - D was watching the events from inside the chamber and alerted Grievous to the Jedi ' s presence . As the general spun around and headed over to confront the intruders , Vebb decided to remain outside of the command center and fight Grievous himself , despite Fisto ' s protest . Before the Jedi Master could convince Vebb otherwise , EV - A4 - D remotely closed the door , separating Fisto from his former Padawan . Vebb quickly eliminated the three MagnaGuards , but turned to see Grievous with two more of his droid bodyguards . After eliminating the remaining MagnaGuards , Vebb engaged the general in lightsaber combat . EV - A4 - D meanwhile spectated the duel from the command center ; however , Fisto entered the room and eliminated the caretaker droid . Unable to help his former Padawan , Fisto watched as Vebb and Grievous engaged in a saberlock . The general took out a blaster with one of his extra arms and killed Vebb , stealing the fallen Jedi ' s lightsaber to add to his collection . R6 - H5 soon contacted Fisto , and the Jedi Master told his astromech droid to meet him at the castle ' s south landing platform . Knowing that Fisto was watching from the command center , Grievous stated that the Jedi Master was his next target ; however , Fisto damaged the command center ' s controls before escaping . Duel outside the castle . Fisto exited the castle and walked out onto the outer platform . However , Grievous climbed onto the platform from below to confront the Jedi Master , and as both duelists activated their lightsabers , Fisto saberlocked with the cyborg general . Taking advantage of the moon ' s foggy atmosphere , the Jedi Master deactivated his lightsaber and disappeared into the mist . A confused Grievous spun his lightsabers in a defensive maneuver , and Fisto attacked the general from behind . The two bladelocked once more , and Grievous pushed Fisto backward , slashing at the Jedi Master . Fisto was able to avoid the blow , and as he ran forward he severed the hand of the cyborg that held Vebb ' s lightsaber . Catching the weapon of his former Padawan , the Jedi Master used the two lightsabers in combat against his opponent . The Jedi Master was able to land a blow on the general and Force - pushed Grievous to the ground . However , as the cyborg got to his feet and continued the duel , three of the general ' s MagnaGuards appeared and advanced toward the Jedi , forcing Fisto to break off from fighting Grievous and confront the droids . With the Jedi Master surrounded and outnumbered , the general ordered Fisto to surrender . However , as the Jedi deactivated his lightsabers , R6 - H5 piloted Fisto ' s fighter to rise up to the platform . The MagnaGuards slashed at the Jedi , but Fisto backflipped onto his fighter and , once they were heading away from the castle , the Jedi Master entered the ship ' s cockpit and escaped the moon of Vassek . Aftermath . Returning to his castle , Grievous proceeded to the sanctum overlook chamber , where Count Dooku awaited a report via hololink . Grievous stated that the Jedi had been defeated , and while Dooku revealed that victory over Vebb and the clones had been expected , the Sith Lord was pleased , believing that the general had bested the Jedi Master Fisto . However , Dooku was disappointed when he learned that Fisto had escaped and stated that there was " room for improvement " before severing the connection . Fisto himself returned to the Jedi Temple on Coruscant and reported his mission to Masters Yoda and Mace Windu of the Jedi High Council . Upon learning of Vebb ' s intent to answer Grievous ' s power with that of himself and his deviation from the Jedi way in doing so , Yoda stated that the war presented the Jedi with a danger of " losing who they were . " Behind the scenes . The mission first appeared in " Lair of Grievous , " an episode in the 2008 of the , and was also featured in the young readers ' book " " It introduced the character of Nahdar Vebb as well as General Grievous ' s castle and featured the series introduction of Jedi Master Kit Fisto . The episode also completed a three - episode story arc centered around the capture of Viceroy Nute Gunray that began with the episodes " Bombad Jedi " and " Cloak of Darkness . " There has been much controversy regarding whether the mission took place on the third moon of Vassek or the world of Vassek itself . Both the series ' " " and " " state that it was on Vassek , while the online guide for " Lair of Grievous " states that it was on the third moon . Because of the online guide ' s closer relations to the episode , this article assumes that the mission was to Vassek ' s third moon . Different portrayals . The non - canon computer game " Path of the Jedi " , released on Cartoon Network ' s official site , depicts an alternate storyline with either the Jedi Ahsoka Tano , Anakin Skywalker , or Yoda being sent to aid Fisto . The Nintendo DS version of the 2009 video game " " presents a different portrayal of the mission . Nahdar Vebb is completely absent from the story ; instead , Kit Fisto is assisted only by Clone Captain CT - 7567 — nicknamed " Rex " — and two clone troopers . While the two troopers remain outside , Fisto and Rex infiltrate Grievous ' s castle , and , after navigating through its mazes and fighting numerous B1 battle droids and B2 super battle droids , confront the general himself . After a brief duel with Fisto , Grievous retreats further into the castle , and Rex tells the troopers outside to contact the Republic fleet at the planet Bestine and ask for reinforcements . The troopers , however , fail their mission as the only means to contact Bestine — their " Nu " - class attack shuttle — is destroyed by a Vulture droid . Fisto and Rex continue their pursuit of Grievous , but are forced to split up . Fisto then defeats an IG - 100 MagnaGuard and faces the Separatist general for the second time . After a lengthy battle with Grievous and the droids that assist him , Fisto escapes aboard his interceptor . Following this encounter , Grievous leaves the base , but increases the security inside it . Later , when the Republic faces the need to obtain recent Confederate clearance codes in order to bypass the defensive perimeter of the Separatist - controlled space station Juma 9 , Kit Fisto remembers that during the mission to Vassek his starfighter ' s scanners had picked up an energy reading coming from within the castle . Believing that such energy levels could only mean the presence of a Separatist archive containing the codes , the Jedi dispatch Jedi Master Luminara Unduli and Clone Commander CC - 1004 to retrieve them . Because of such a confusing storyline that would take too much speculation to implement into the pre - existing story , this article assumes that the video game ' s mission is non - canon . The 2011 non - canonical video game " " features the mission in its humorous depiction of " Lair of Grievous . " In the game , Fisto and Vebb engage Grievous ' s forces — several MagnaGuards — before even fighting Grievous himself .
