Attack on Emperor Fel This attack was the last battle of the Sith – Imperial War . In 127 ABY , following the failure of the Ossus Project — an effort to restore planets damaged during the earlier Yuuzhan Vong War — the Galactic Empire declared war on the Galactic Alliance . A year into the war , the Sith Order emerged , offering to ally with the Empire and help to defeat the Alliance ' s Jedi . With the Empire bolstered by the Sith , the Alliance surrendered in 130 ABY . Following the surrender , the Dark Lord of the Sith , Darth Krayt , arrived on Coruscant , where he confronted a double of Emperor Roan Fel during a meeting with the Moff Council . In the mistaken belief that the decoy was Fel himself , Krayt stated that his Sith Order had helped win the war and now he sought his reward — Fel ' s life . Krayt and his Sith killed the Emperor ' s protectors and the decoy , with Krayt then pronouncing himself emperor . Prelude . Around 127 ABY , the Yuuzhan Vong terraforming project — an effort that sought to restore planets that had been damaged during the Yuuzhan Vong War a century earlier — began . However , many things went wrong , resulting in a number of mutations on the planets where the project was taking place . Angered by this , the Galactic Empire — which had never forgiven the Yuuzhan Vong for the war — declared war on the Galactic Alliance , which had supported the Ossus Project at the urging of the New Jedi Order . The ensuing war began poorly for the Empire , as the Jedi proved to be a tremendous advantage for the Alliance . A year into the war , however the Sith Order emerged , offering to assist the Imperial forces . The Empire accepted their offer , and thanks to the Sith , the tide began to turn . However , unbeknownst to Emperor Roan Fel , the Sith had caused the Ossus Project to fail and had approached Grand Admiral Morlish Veed and Moff Nyna Calixte earlier with an offer of alliance . They had also promised to overthrow Emperor Fel and replace him with someone stronger . Veed assumed that the Sith were referring to him , and he and his lover Calixte accepted their offer , later manipulating the Moff Council into accepting the Sith ' s deal when the time came . Following the Alliance ' s surrender in 130 ABY , Darth Maladi met with Calixte and Veed , who had recently been named High Moff , onboard Veed ' s flagship , the " Imperious " . She explained that the time had come to remove Fel from the throne , and they planned to do so during a meeting that Fel had scheduled with the Moffs in the upcoming days . However , Calixte had second thoughts and feared that the Sith would instead name their leader , Darth Krayt , emperor . She warned Fel in secret , informing him that the Sith intended to kill him . Fel decided to place a double on the throne at the meeting . The attack . The meeting went ahead as scheduled , with Fel and the Moffs discussing the terms of the Alliance ' s surrender . Halfway through the conference , Darths Krayt , Maladi , Nihl , and Wyyrlok arrived . Fel ' s decoy asked what reward the Sith wanted for their assistance in the war , with Krayt responding that he sought the Emperor ' s life . Fel ' s Imperial Knight bodyguards moved to protect Fel ' s double ; however , they were no match for the Sith . Mohrgan Fel and Fel ' s three other protectors were quickly killed . Krayt then killed Fel ' s decoy and declared himself Emperor . With the war now over , Krayt stated , he would put his grand vision into action . Aftermath . Krayt quickly realized that the man he had killed was not Fel , as the former Emperor was skilled in the Force and lightsaber combat and thus surely would have fought back , while the faux Fel had not even tried to resist . Krayt proclaimed Fel to be a fugitive from Imperial justice , and his agents began searching for him . Fel and the faction that remained loyal to him spent the next several years launching hit - and - run attacks on Krayt ' s Empire . Seven years later , Fel still remained at large , much to Krayt ' s displeasure . Meanwhile , a short time after the assassination attempt , Maladi visited Calixte at her apartment and accused her of informing Fel of the imminent attack . Before leaving , Maladi threatened Calixte , telling the Moff that she now served the Sith Lord . Behind the scenes . The attack on Emperor Fel first appears in the first issue of " " , " " . It later appears in a flashback in " " , which depicts part of the attack from Calixte ' s point of view . " The Essential Atlas " incorrectly places the attack in the year 137 ABY .
