Zeta Magnus Zeta Magnus , also known as K ' am ' ir Zaarin , Saturna the Garu , and Eon Null was a male Arkanian mutant and a master geneticist and an enemy of the Galactic Republic . Believed to have orchestrated several terrorist attacks across the galaxy , Magnus was affiliated with the Confederacy of Independent Systems during the Clone Wars . Declaring himself Magister of Skye , Magnus unleashed a pathogen on the planet and oversaw the Battle of Skye . Biography . Born as an experiment by the Arkanian Dominion , the male Arkanian mutant named Zeta Magnus was created to serve as the prime clone of the Accelerated Transgenic Heuristic Abhorer s . These Abhorers , an answer to the Arkanian Renegades ' Assimilator s , were created from the DNA of Yaka , rakghoul s , Amorphiian android s , dianoga , and other horrors to serve the Dominion . Unleashed during the Arkanian Revolution , Magnus slaughtered countless enemies of the Dominion with his accelerated strength . After the Revolution was ended , the Dominion destroyed its Abhorers but failed to kill Magnus , who escaped his hunters and fled captivity . After eating his creators , Magnus began his search for new ways to quench his desires for violence and mental stimulation . A killing machine , Magnus learned the languages of each of his victims as well as teaching himself to play instruments such as the Mawanese vioflute , the drumheller harp , the B ' omarr pipe nalargon , and the Zeltronian lute . A savant thanks to the noological implants in his brain , Magnus was a genius . Traveling the Unknown Regions , Magnus interacted with a schizophrenic bio - ship , the Vagaari , N ' Gai , and Ebruchi species , as well as the Chiss Ascendancy and the Ssi - ruuvi Imperium before establishing a kingdom of Dark Worlds which would come to be blessed by the Sorcerers of Rhand . Upon the realization that he was genetically programmed to die , Magnus sought immortality and was thus approached by Darth Sidious , Dark Lord of the Sith . Sidious promised to help Magnus live forever in exchange for fealty . While Magnus intended to eat the Sith Lord , he agreed to meet with him and see what he had to offer . To this end , Magnus became known as a terrorist to the Galactic Republic . Orchestrating an infestation of stone mites in the Core Worlds , creating and unleashing the blue virus , gifting General Grievous samples of 3L41UH7 serum , and allowing Count Dooku and the Confederacy of Independent Systems to use Wayland as a base and lab wherein the dashta tissue samples and Morgukai Shadow Army might be experimented with . Magnus also operated a GeNode facility hidden deep on Dantooine that persistently eluded Jedi Master Mace Windu . When he assisted in reviving Grievous and making him into the robotic monstrosity he became , Magnus requested a payment of a doublenecked , eight - string quetarra . During the early stages of the Clone Wars , infamous terrorist Zeta Magnus was wanted by the Republic for several of these notable crimes . A geneticist , Magnus was believed by Senate Bureau of Intelligence to have orchestrated a slew of murders on Anaxes and the hive virus which crippled the Katana fleet . A clone of Magnus invaded the planet Marat V in the Marat system and subjugated the native S ' kytri people . When the Jedi Order learned of his involvement on Marat V , the Jedi High Council dispatched Jedi Knight Obi - Wan Kenobi and Padawans Halagad Ventor and Anakin Skywalker to apprehend him and bring him into custody . While they were joined by Captain Brisha Shard and her MedStar frigate called the " Golandras " , Captain Shard ' s ship was ambushed and destroyed over Marat V . Evacuating the ship via three escape pods , the Jedi crash - landed on the planet accompanied by four clone commandos : Nilo , Xoni , Quo , and Kupe formed Tark Squad . While Magnus joined forces with the Outland Clan far from the main population centers where his pathogen had taken hold , the Jedi met with Patriarch Klarymére of the S ' kytri and prepared to hunt him down . Having established a citadel upon the sacred Canaitith Mountain , Magnus ' Outlanders led assaults on the S ' kytri and continued to spread the pathogen he introduced to their environment . As the Jedi met with the Supreme Council of the Highland Clans , the Magnus clone released a HoloNet News transmission accusing the Jedi of interfering in his sovereignty over Marat V and ordered them to be recalled lest he unleash a plague upon the world of the Republic . Unknown to Magnus , the Jedi planned an attack on his citadel by navigating the perilous labyrinth of the Entyrmion ' s subterranean tunnels . During their travels , the Jedi began to wonder at the identity of Magnus and his true nature . Ventor wondered if he might be Force - sensitive and the title , Saturna the Garu was any relation to the ancient Sith Lord Garu . Additionally , as Master Windu was interested in the arrest of the geneticist , the possibility of a connection with the Dantooine Garoo seemed plausible especially in light of Windu ' s recent exploits on that world . Ventor also pointed out that Magnus was an ancient Sith title meaning " Lord of Lords . " These questions led the Jedi to consider that Magnus could be the rumored and mysterious Second Sith . Interrupting their musings , the Jedi and S ' kytri warriors were attacked by an Oskan blood eater , a concoction of Magnus which attacked them in the sweltering crystalline caverns . Despite this , the Jedi forced their way into the citadel at the summit of Canaitith just as the S ' kytri launched into battle against Magnus ' Outlanders . As the Jedi searched for their target , the three were betrayed by their clone commandos , who were in actuality thralls of Magnus himself . The four faux - clones were revealed to be Sun Guard s when the Jedi awoke in the laboratory of Magnus himself . Standing over them , he relished in their deception and taunted Ventor as he recounted orchestrating the event which saw his parents consumed by a hive - virus . Magnus planned to scan the brains of the Jedi and implant them in clones which he could grow in a matter of hours . Displaying the Jedi clones already forming at the other end of the chamber , Magnus was interrupted by the S ' kytri warrior Kharys , who blasted away the restraints from the Jedi and freed them . Fleeing with his droid , Blue Tark , Magnus was pursued by Ventor as Kenobi and Skywalker dealt with the Sun Guard . Heading for the hangar , Magnus ' ship , the " Skyriver Invader " was not primed for take off which allowed Ventor to keep up with him . Struck in the back by a liquid cable spike , Magnus was dragged to the ground by a furious Ventor . The battle went ill for Ventor , who lost several fingers and chunks of his flesh to the monstrous being , but was able to get the upper hand when the " Skyriver " ' s engines ignited and irradiated Magnus . Using his lightsaber , Ventor bisected the man , killing him . This however was not the original Magnus . For he remained far away within his Dark Worlds , on the throne world of Rennek . From here he released the first plague into the Republic as he had promised . At some point after the Battle of Endor , TriNebulon News reporter Andor Javin filed a report claiming that K ' am ' ir Zaarin was the real identity behind the Imperial agent Cronal / Blackhole , known at the time as the rogue warlord Shadowspawn . Javin stated that the Arkanian had an army of clone warriors and worked alongside a clone of the then - deceased Grand Moff Wilhuff Tarkin . Personality and traits . A craven Arkanian , Zeta Magnus was fond of dressing in the garb of the ancient Magi Sentinels of Onderon . Behind the scenes . Author Abel G . Peña had stated that he intended the genetic terrorist to be Atha Prime , but the mention was cut before final release . The description of K ' am ' ir Zaarin working in league with a " resurrected " Grand Moff Tarkin as well as having an army of Clone Warrior s , mirrors that of the description of the character Atha Prime . Prime was described as a " genetics master " and an " architect of the Clone Wars " and was to be the primary antagonist , along with Tarkin , of the cancelled " The Epic Continues " storyline developed by Kenner Products . Kenner invented the character as a primary antagonist to further their SW toy line following . Abel G . Pena , the co - writer of " The Imperial Warlords : Despoilers of an Empire " , has several times attempted to canonize Atha Prime and make references to the cancelled storyline , making this connection deliberate .
