Sifo - Dyas / Legends Sifo - Dyas was a male Human Jedi Master who served the Jedi Order during the last decades of the Galactic Republic . When the Sith were revealed to have returned during the Invasion of Naboo in 32 BBY , Master Sifo - Dyas secretly commissioned the creation of a clone army , placing an order with the Kaminoan government before he was murdered by his friend , Count Dooku . Biography . Jedi Master . A Force - sensitive Human gifted with precognition , Sifo - Dyas hailed from the Cassandran Worlds and was raised in the Jedi Order . Like most of the Jedi of his time , he was inducted into the Order at a very young age and taught the ways of the Force at the Coruscant Jedi Temple . Sifo - Dyas constructed his own blue - bladed lightsaber and eventually attained the rank of Jedi Master . He became a close friend of Master Dooku and the two were often seen in public together . Master Sifo - Dyas was chosen to sit on the Jedi High Council , but was removed from that position at some point prior to the Blockade of Naboo because his ideas were judged to be too extreme by the other members . In 52 BBY , Master Sifo - Dyas accompanied Dooku , Jedi Master Qui - Gon Jinn , and Jedi High Council member Jocasta Nu to a meeting on the world of Serenno . After four hours of rigorous debate , a brief recess was called , and the Jedi were confronted by Damask Holdings magister Hego Damask , in reality , the Dark Lord of the Sith Darth Plagueis . Damask aired his concerns for the future of the Republic , and both Dooku and Sifo - Dyas responded to this with their own concerns . Sifo - Dyas was quite stern with his answers and reluctant to agree with what both Dooku and Damask seemed to agree on . Sometime after , Sifo - Dyas and Dooku were present at the Senate Building and met Senator Palpatine of Naboo , in reality , Damask ' s Sith apprentice ( and Dooku ' s future master ) Darth Sidious . As his friend Dooku grew disillusioned with the Jedi and the Senate , Sifo - Dyas grew concerned . He became convinced that very dark times were ahead , but the Jedi Council paid little heed to his warnings . In 32 BBY , a gathering was hosted by Supreme Chancellor Finis Valorum on Coruscant . Sifo - Dyas was in attendance alongside Jedi Yoda , Mace Windu , Adi Gallia , and Jorus C ' baoth . Once again , Hego Damask approached Sifo - Dyas , and once more he openly admitted that a growing darkness was approaching , as he stated to the Jedi twenty years before on Serenno . Sifo - Dyas agreed to Damask ' s claim and Damask informed him of cloners on Kamino that could grow an army and hold it in reserve until it was needed . The Jedi Master was at first skeptical of this , but was persuaded to think about it . Not long afterwards , Sifo - Dyas approached the Kaminoans and requested a clone army for the Republic . With the funds provided by Damask Holdings , Sifo - Dyas paid the Kaminoans . At around the same time , Sifo - Dyas was contacted by Supreme Chancellor Finis Valorum , who knew of the Jedi Master ' s expertise on the criminal underworld , and given a secret mission to negotiate with the Pyke Syndicate of Oba Diah . Because the Senate committee assigned to the Pyke case wanted to keep negotiations between the galactic government and a criminal organization strictly under the table and away from the public eye , Sifo - Dyas did not inform the Jedi Council of his mission . It was at around that time that Dooku resigned from the Jedi Order and fell to the dark side of the Force , joining the Order of the Sith Lords as Darth Tyranus , apprentice of Darth Sidious . Little did Sifo - Dyas know that Sidious and Dooku had learned of his ordering the clone army and planned the steps to his demise . The first test provided to Dooku was to murder his old friend . In doing so , he would fulfill the ancient covenant that prescribed the murder of one who was close as a measure of commitment to the Sith cause . By executing the man , Dooku would gain full control of the project for the Sith , using Sifo - Dyas as a cover . Seeing that Dooku had embraced the dark side , Sidious awarded him the Sith name and title of Darth Tyranus . Sifo - Dyas arrived on Oba Diah together with Valorum ' s personal assistant Silman , but the secret Pyke - Republic talks were postponed , as the Jedi Council contacted Sifo - Dyas and assigned him a mission to negotiate peace talks between Jungle Felucian tribes on Felucia . However , the two men never reached their destination , as the Pykes were contacted by Tyranus . The Syndicate , wishing to gain an advantage over rival crime families , struck a deal with Tyranus , who paid them a very large sum . At Tyranus ' s behest , the Pykes shot down Sifo - Dyas ' Jedi T - 6 shuttle 775519 over Oba Diah . The ship crashed on the planet ' s small habitable moon . As proof of the fulfillment of their deal , the criminals recovered the Jedi ' s corpse from the wreckage and turned it over to Tyranus , taking Silman — who had survived — prisoner as insurance . Sifo - Dyas had been betrayed and killed by his old friend , but the cloning project still stood , so Dooku carried on where Sifo - Dyas left off . Until he had been silenced , Sifo - Dyas had kept the project a secret . To ensure that it " stayed " a secret , Dooku erased all records of the planet Kamino from the Jedi Archives , along with thirty - seven additional systems , including Dagobah and Dromund , that Sidious had judged to be of potential value to the Sith — this all being done after having publicly renounced and left the Jedi Order . The official records of the Galactic Republic on Sifo - Dyas — classified as " File 127456 " — told a different story . According to the file , Jedi Master Sifo - Dyas perished while trying to negotiate peace between several tribes on Felucia , adding that he was aboard a shuttle that crashed on the planet ' s surface . The records went on to say that his body was eventually removed by the Felucians , who treated it in accordance to their customs , providing an explanation as to why the body was never found . Sifo - Dyas ' file stipulated that " much of the information surrounding his death [ remained ] confidential under the Office of the Chancellor , " although " further investigation in the matter [ might ] be authorized at a future date . " Legacy . Instead of disposing of his old friend ' s body after it was handed over to him by the Pykes , Dooku preserved it in a cryogenic hibernation capsule for years , until the InterGalactic Banking Clan initiated their plan to turn the Kaleesh warlord , General Qymaen jai Sheelal , into a great cyborg supreme strategist . Transfusing Sifo - Dyas ' blood into the veins of the cyborg , Grievous would go on to become the Supreme Commander of the Confederacy of Independent Systems ' droid army . Once Grievous ' transformation into a cyborg had been successfully completed , Dooku gave him the very special gift of Master Sifo - Dyas ' own lightsaber ( presumably a different one than that he carried to Oba Diah , which remained in the shuttle wreckage on the Oba Diah moon ) . In 22 BBY , 10 years after Sifo - Dyas ' s death , Jedi Knight Obi - Wan Kenobi ' s investigations led him to Kamino , the source of the saberdart that silenced Senator Padmé Amidala ' s attempted killer Zam Wesell . There , in Tipoca City , Kaminoan Prime Minister Lama Su told Kenobi that Sifo - Dyas had ordered the creation of a clone army at the request of the Senate , in order to help the Galactic Republic . Su was under the impression that Sifo - Dyas was a member of the Jedi Council at the time he made the order , and did not know of Sifo - Dyas ' s demise . Realizing that a discrepancy in the timeline may exist , Master Kenobi contacted the High Council and revealed the existence of the army . Sifo - Dyas ' army was eventually revealed and used at the behest of the Galactic Republic . The conflict between the Separatists and the Republic was , in fact , named after it . In the third year of said conflict , as part of the Sith illusions created by Darth Sidious and Darth Tyranus ' s dark side ritual , Sifo - Dyas appeared to Yoda on Korriban . His specter was being tortured , bound by electricity , and begging Yoda to release him . However , Yoda saw through him with his Sith eyes , causing him to merge into Sidious . In 19 BBY , Sifo - Dyas ' s army was used by the Chancellor to destroy the Jedi Order in accordance with a Sith plot a millennium in the making . In this way , Sifo - Dyas , manipulated by the Sith Lords , had a hand in the destruction of the Jedi Order in his effort to save it . Behind the scenes . In early drafts of " " , the name of the Jedi who contacted the Kaminoans was Sido - Dyas , pointing to a likely early conceptual connection to Darth Sidious . However , " Sifo - Dyas " appears in one place , apparently as a typing mistake ( as the D and F keys are next to each other on a QWERTY keyboard ) that Lucas later preferred to the original name . In addition , " Sido - Dyas " was originally only a false identity for Sidious — Obi - Wan Kenobi claimed never to have heard of him , and Mace Windu confirmed that there was no Jedi by that name . His backstory was promised by George Lucas to be revealed in " " , but instead was explained in the lead - in novel " Labyrinth of Evil " . The character ' s name was changed to Zaifo - Vias in Brazil . The original name is phonetically similar to a vulgar expletive in Brazilian Portuguese , so this was done to prevent confusion . The first visual appearance of Sifo - Dyas was in " The Eyes of Revolution " comic featured in " " . The story was written and drawn by Industrial Light & Magic concept artist Warren Fu , and as an easter egg , or inside joke , Fu used himself for the face of the Jedi Master . Artist Chris Trevas noticed Fu ' s likeness in the comic while doing research for his own illustration of Sifo - Dyas in " " . For the sake of continuity , and respect for a fellow artist , Trevas contacted Fu to reprise his role for the " Jedi vs . Sith " illustration as well . In 2014 , the episode " The Lost One " of the unveiled more details about Sifo - Dyas ' s last moments and the exact manner of his death .
