Helm of Ieldis The Helm of Ieldis was a Sith Lord Ieldis creation in the years prior to the Great Hyperspace War . It was a helmet imbued with the powers of the dark side . When worn by a Force - sensitive Dark Sider , the Helm was capable of converting negative emotions like grief , anger and misery into Dark Side energies capable of driving sentient beings into a homicidal frenzy . History . It was a Sith artifact crafted after years of study by Ieldis into the nature of conflict between people and what drove them into throwing their lives away . The Helm was capable of manipulating negative emotions like grief , anger and misery and channeling into Dark Side energies which drove entire armies into a homicidal frenzy . At some point after the destruction of the Sith Empire , the Helm was hidden on the world of Sarrassia by the Grumani Hierophant s . They hid it in an underground temple beneath Mount Diligence . Later , it was moved to Skarpos , a bleak desert world where the Grumani had a temple in the Morbollon Mesa . During the Republic Dark Age , a University of Sanbra research team began a preparations for a scientific expedition to locate the Helm with the cooperation of the Jedi Order . The Sith Lord Odion raided Sanbra , and learnt about the existence of the Helm . He then captured the researchers on Aquilaris Minor and conscripted them into his top - secret Project Pandemonium which aim to seize the relic before his Sith compatriots could lay their hands on it . This research team included the archaeologist Mercia Holt and her husband Aron Holt , the parents of Jedi Knight Kerra Holt . In 1038 BBY , their last recorded trail stopped at Sarrassia . It was later revealed that the Holts had sacrificed themselves in an attempt to destroy the Helm by triggering an explosion . While the surrounding Grumani temple chamber was badly damaged , the Helm survived since it was a Sith artifact . In 1032 BBY , Kerra infiltrated the Novitiate s , Odion ' s elite Force - sensitive corps of acolytes , using the alias " Mercy . " During the Invasion of Sarrassia , she learnt from Aunt Zoojoo that the Helm of Ieldis had been relocated earlier to Skarpos , a war - torn planet in Lord Malakite ' s realm known as the Menagerie . During the Second Battle of Skarpos , the Helm was located by Odion himself who had taken a shuttle to the planet . He found the Helm of Ieldis within a cave excavated by Grumani Hierophant s , beating his own team of hunters . Meanwhile , Kerra located the cave , damaging the airspeeder carrying her fellow hunters so that they could not follow her . Within the interior chambers , she located her mother Mercia ' s satchel but found no sign of her parents . Kerra was then attacked with Force lightning by Odion himself , who praised Kerra for leading him to the Helm before acknowledging her true identity . He then announced that she would be the first to witness it in action . Odion would then used a captive Kerra to activate the Helm of Ieldis ; she had succumbed to grief after learning about the deaths of her parents . Odion would use the Helm to annihilate three entire armies on Skarpos , forcing his rivals Daiman and Malakite to flee into hyperspace . A jubilant Odion then took the Helm to Vanahame , which was home to a planet - sized orphanage known as a cloister . There , he would used the misery and anxieties of the captive children to unleash the Helm on a galactic level to destroy all sentient life in the galaxy to fulfill his desire to be the only sentient being . During the Battle of Vanahame , Odion shut down the lights in the cloister , bringing about panic and dismay in the children , and thus obtaining the energies to power the Helm . He then started to use it to bring about a wave of mass murder throughout the Grumani sector ; however , he was thwarted when his General Beld Yulan , who had been convinced by Kerra to turn against him , freed the captive children , and the rush of positive emotions such as joy and happiness caused the Helm to malfunction and explode , destroying it and killing Odion .
