Tarr Seirr Tarr Seirr was a male Cerean Jedi Knight who fought in the Clone Wars against the Separatists . Raised by the Jedi Order , he became a Jedi Watchman for his home system Cerea , and helped advise the planet ' s government during the Separatist Crisis . When the Clone Wars broke out , he was transferred from Cerea to fight alongside his long - time idol , Jedi Master Ki - Adi - Mundi . In 22 BBY , he was selected to be a part of the elite task force sent to destroy a droid factory of the Confederacy of Independent Systems in planet Hypori . However , the Republic fleet , which carried the Jedi and their clone troopers , were blasted out of the sky before they could even land . Only Seirr and five other Jedi managed to survive the crash landing , but they were quickly surrounded by a droid army under the command of General Grievous . After the remaining Jedi took a shelter from one of the crushed assault ships , Grievous ordered the droid forces to stop , and personally entered hand - to - hand combat with the trapped Jedi warriors . During the fight , Seirr tried to strike Grievous from behind , but he was grabbed by the cyborg general ' s clawed foot and crushed to death . Biography . Early life . Born on the planet Cerea and raised by the Jedi Order , the Cerean male Tarr Seirr always idolized Ki - Adi - Mundi , a Cerean Jedi Master and a member of the Jedi High Council who served as the Watchman for the Cerean Quadrant for decades . After passing his Trials of Knighthood , Seirr was elevated to the rank of Jedi Knight . During the growing Separatist Crisis , members of the Council found themselves too occupied , and Mundi relinquished his position as Watchman to Seirr . Shortly before the Clone Wars , when Cerean government indicated the planet ' s uncertainty to officially side with the Galactic Republic , Seirr advised the Cerean government to join the Republic to prevent the planet from falling to the Separatists of the Confederacy of Independent Systems . However , Cerea ultimately chose neutrality during the war . Attack on Hypori . When the Clone Wars broke out in 22 BBY , the Jedi Watchmen were scattered to different battlefront locations , and Seirr was reassigned from Cerea to a strategic battlefront location . He was secretly reluctant to depart from his homeworld , as the planet was left susceptible to danger of the Separatist invasion , but nevertheless obeyed the order and left Cerea . As the Clone Wars raged on , Seirr had a chance to fight alongside his role model , General Ki - Adi - Mundi . Around 22 BBY , Jedi General Daakman Barrek uncovered a massive CIS droid factory on planet Hypori . An elite task force , consisting of Barrek and his Padawan Sha ' a Gi , along with Seirr , and Jedi Generals Ki - Adi - Mundi , Aayla Secura , Shaak Ti and K ' Kruhk were dispatched to the planet to destroy the factory , reinforced by an army of clone troopers of the Grand Army of the Republic . However , the mission turned out to be a disaster ; as the Republic ships emerged from hyperspace , Confederacy ' s orbital mines caused the majority of the transports to crash to the planet , and straight behind the Separatist ' s lines . Seirr and the other Jedi survived the landing , but nearly all clone troopers were killed . The situation rapidly grew worse when the survived troopers were surrounded by a massive droid army that was stationed on the planet under the command of the Supreme Commander of the Droid Armies , General Grievous . During the ensuing fight , Seirr received a wound on his left arm , Barrek was killed by Grievous , and all remaining clone troopers were shot by droid forces . Separated from other survivors and chased by B2 super battle droids and OG - 9 homing spider droids , Seirr and Ki - Adi - Mundi tried to retreat on one of the crashed cruisers . Grievous , who wanted to slay the Jedi personally , ordered the droid army to halt , while Seirr and Mundi ran inside the wrecked ship , where they reunited with the other Jedi . Moments later , Grievous told the survivors to prepare to meet a " warrior ' s death " , and started to move toward the wreckage . Final duel . Inside the ruined ship , the Jedi activated their lightsabers , preparing to face off against the cyborg general . However , scared by the approaching threat , Padawan Sha ' a Gi mentally broke , and rushed out of the ruins . Grievous quickly crushed him on earth , killing him , and hid inside the ship . The remaining Jedi backed off in the center of the cruiser , but were suddenly attacked by the reemerging Grievous , who leaped from shadows in the middle of the Jedi . Although the Jedi hunter was surrounded , he managed to hold his own during the duel . Grievous soon gained the upper hand , and after striking Seirr and the rest of the Jedi away , he severely wounded K ' Kruhk , who fell unconscious . Shaak Ti then used telekinesis to throw scrap metal against Grievous , while Seirr tried to defeat the general by striking him in the back . However , Grievous blocked the metal with his lightsabers , and after noticing Seirr , grabbed the Jedi Knight ' s head with his cybernetic foot , and crushed Seirr ' s head against the ground , killing him . He then threw the lifeless body of Seirr against the roof along with injured Aayla Secura . Only Ki - Adi - Mundi and a severely wounded Shaak Ti , Secura , and K ' Kruhk survived the engagement . Later on , Seirr ' s fears transpired to be reality when unprotected Cerea became a battleground as Republic and Separatist forces fought to claim its allegiance . As a result , much of the serene wilderness of the planet was despoiled in the fighting , and many Cereans were killed . Personality and traits . Raised by the Jedi Order , Tarr Seirr strongly believed in the Jedi cause . He respected the Jedi Code , even when it meant to leave something important behind ; when he was assigned to a more tactical location from his homeworld Cerea , he hid his reluctance of leaving the planet to a danger and obeyed the assign . He was very fond for Cerea , and didn ' t want it to join the Separatist cause . Seirr greatly revered Jedi Master Ki - Adi - Mundi , and when he relinquished his position as Watchman to Seirr , the young Cerean took the role very seriously , and helped advise the ruling Cerean government during the Separatist threat . During the Battle of Hypori , Seirr asked Mundi ' s advice during their retreating , and stayed close to the Jedi Master even inside the shelter ; when Mundi tried to stop Padawan Sha ' a Gi for bolting , Seirr was the first Jedi who followed the Cerean Jedi Master . Seirr was seemingly nervous when General Grievous approached , but didn ' t later hesitate to attack the cyborg . Powers and abilities . A Jedi Knight , Seirr was an accomplished swordsman , his skill with a blade rivaling many Jedi Masters . Favoring Form 4 , Ataru , Seirr proved to be an adept duelist , and because of this , as well as his Cerean heritage , he was selected to succeed Ki Adi Mundi as the Jedi Watchman of the Cerea System . Even with the combined strength of him and the four Jedi generals , however , he was unable to defeat Grievous , who blocked and dodged the lightsaber strikes of the Jedi and ultimately killed him .
