Krath Holy Crusade The Krath Holy Crusade ( 3997 - 3996 BBY ) was a series of battles fought before and during the Great Sith War , and comprised the bulk of that conflict . The crusade was a culmination of events that began with a violent regime change in the Empress Teta system staged by Aleema and Satal Keto , heirs to the Tetan monarchy and also leaders of the Sith - inspired Krath cult . After the war , the Krath order constructed a series of temples on several of the worlds they had seized during the Crusade . This Crusade started as the Mandalorians began their holy crusade against the Basiliskan s on Basilisk , and ended after the defeat of Dark Lord of the Sith Exar Kun on Yavin 4 . Origins . Dark side awakening . In the year 3998 BBY , two young nobles from the Empress Teta system arrived on Coruscant . Satal Keto and his cousin Aleema , the heirs to the Tetan monarchy , were on a vacation of sorts to the Galactic capital . Upon arriving on the capital world in their royal yacht dubbed the " Krath Enchanter " , the Ketos started their trip by visiting Coruscant ' s Galactic Museum . In truth , they had come to Coruscant in search of knowledge of the ancient Sith , and more specifically , for anything related to the dark side . At the time of the Ketos ' arrival , the museum had nearly completed a new dark side - based exhibit , appropriately titled " " Dark Lords of the Sith " " . The Ketos begged to be allowed to explore the incomplete exhibit , but the curator was hesitant due to explicit instructions from the Jedi Order that the hall be off limits until a sufficient security detail was in place . The Ketos continued to beg , and finally the curator relented . They were then allowed access to a hall dedicated to the Sith was filled with ancient and priceless artifacts , books , tomes , and amulets , all radiating with dark side power ; power that Satal and Aleema could feel through the Force . They quickly stole one of the books and fled back to their lodging quarters . Unable to read the book and dejected by that fact , the Ketos ' hope was renewed when they heard a news report about dark side adept s on Onderon who practiced ancient Sith magic . They knew that Onderon was where the secrets of the book had any chance of being revealed to them , and they immediately left Coruscant on a course for the dark side world . Violent political regime change . Returning to their system , the cousins began a coup to overthrow their parents ; they confused everyone with Sith illusions . They then killed their parents by dipping them in molten carbonite . The war . Last stand of Empress Teta . The Krath forces launched an attack at the last free planet , Koros Major . Aleem assisted her forces through use of her Sith powers . Luckily , a detachment of Republic forces jumped into Koros Major ' s space to assist the barely holding planet . But out of nowhere , myths though extinct space grazers appeared . Jedi Knight Nomi Sunrider saw through the illusions and told the Republic forces to ignore them and concentrate on the stations . Satal pulled a trump card against the Republic by sending out the chaos fighters . Nomi assumed all of them were illusions and telepathically attacked Aleema , who was providing some of the illusions , distracting her , not realizing most of them are real . The fighters slammed kamikaze into the Republic forces , forcing them to retreat . Ambush on Deneba . Meanwhile , the Krath were enjoying their recent victory over the Republic . Back in their Iron Citadel stronghold , Satal Keto tended to his loxed out cousin Aleema , who through the power of Nomi Sunrider ' s psychic attack was rendered comatose . When she finally came around , Satal quickly brought Aleema up to speed on the current situation . He told her that the Jedi and Republic fleet had been driven away , thanks to the power of Sith magic . He also told Aleema of the Jedi convocation being held on Deneba . Satal managed to insert one of his Tetan Corsair s in orbit around Deneba for the next stage of his plan . At an appointed time of Lord Keto ' s choosing , the Corsair would deploy its full concomitant of life - pod s , each carrying an assortment of Krath war droid s . The second prong of the attack would be on the planet ' s surface itself ; Satal planned to use the Jedi ' s service droids against them , supplanting their original programing with that of his own Krath war droids . Once the life - pods were deployed , a signal would be transmitted from the Corsair , activating the service droid ' s programming trap . Chiming the Corsair captain via comlink , Lord Keto ordered him to begin the assault . The Jedi were just barely able to escape the ambush , even as Cay ' s servant droid met a swift demise from the blade of Nomi Sunrider ' s lightsaber . But Cay ' s was not the only droid affected by the program trap . All of the Conclave server droids received the Krath transmission , and instantly began attacking their Jedi owners . Cay thanked Nomi while reminding everyone how he warned them of the droids ' suspicious behavior . Much to his horror his notions were validated as he and the other Jedi were forced to dodge heavy blaster fire . On top of that , Krath war droids were emerging from the life - pod wreckage . The Jedi took the battle directly to them , leaving hundreds of lightsaber - cleaved droids lay strewn across the battlefield . Master Jeth demonstrated one of the more subtle uses of the Force ; to reach inside of the droids , and disable their inner - workings . Many more droids fell under Master Arca ' s droid disabling technique , and Ulic complimented the ability . Just as he was speaking , a war droid blindsided him , and prepared to finish him off . But Arca was aware of Ulic ' s peril and again used the Force to destroy the droid . As he diverted his attention to speak to Qel - Droma , one of the downed droids activated its secondary systems , and fired a blaster shot into Jeth ' s back , felling the Jedi Master . Standing behind him was the war droid he just saved Ulic from , blaster still raised and smoking . As the droid mocked them , Qel - Droma gave into his rage and vanquished the droid . He then rushed to his Master ' s side , to hear Arca ' s last words of wisdom and encouragement ; to fight the dark side , not align with it . Arca told his former apprentice that he had a weapon that the darkness could not withstand : the power of the Light . He then became one with the Force , leaving only his Jedi robes behind . Jedi defector . Convinced that the only way to stop the Krath is to get inside them , Ulic proposed he personally infiltrate them . Though the Jedi Masters were appalled at the idea , they reluctantly allowed him to try it out . But before he left , Master Odan - Urr showed him , through a Sith holocron , how the Sith spend their lives — literally . Qel - Droma ' s arrival in Cinnagar did not go unnoticed ; the Krath were well aware of his presence . He was prepared to kill the young Jedi but Aleema just told him to wait . The next day , she was ready to execute a prisoner when the crowd began rioting . Qel - Droma ' s rescue . Worried about Ulic , Nomi spearheaded a mission to Cinnagar to rescue him . She allowed herself to be captured , just as Ulic was helping the Tetans advance their technologies . Suspicious , Satal had Nomi brought before Ulic and was going to execute her , but Qel - Droma said that he would do it himself the next morning to maintain his cover . He sent a service droid with a message still detailing his mission to Nomi ; however , it was intercepted by Satal . Furious at this betrayal , Satal ordered his servant Norgor to kill Ulic and have Nomi brought to him . Ulic was not caught off guard after sleeping with Aleema , though . He learned of Satal planned attack at Deneba . Enraged , he decided to search for Satal as Nomi escaped the dungeons . Death of Lord Keto . Satal merely taunted Ulic as the two fought , only to be slain by Ulic who had submitted to his anger .
