He subsequently received a doctorate , and following the breakout of the Great Galactic War , he was present on the Imperial dreadnaught " Warhammer " and was one of two individuals aboard who evaded capture when Republic soldier s boarded . Lokin was first identified as Fixer Fifteen during , which saw the Republic Strategic Information Service keeping a dossier on his activities . Lokin was apparently well - acquainted with the former Imperial agent known as Keeper that went on to become the Minister of Intelligence , noting that the Minister had his eternal respect . During the pre - war years he was also a friend and technical adviser to Cipher Twelve whom he had met in the Old Guard before the agent ' s assassination , and expressed their shared interest in Mirialan cuisine , during a conversation with the agent known as Cipher Nine in the war that followed over a decade after the Treaty of Coruscant . He was known for conducting extensive research on the Rakghoul plague and created a custom variant , unique to his DNA , that allowed him to switch between Human and Rakghoul forms at will , while retaining the same personality and intelligence . Cipher Nine encountered Lokin on Taris in Nasan Godera ' s laboratory . While Cipher Nine ' s mission was to investigate a Jedi called Ki Sazen , Doctor Lokin falsely claimed he was sent by Watcher Four for a clean up operation , and to catalogue the contents of Godera ' s lab . The two decided to pool resources to complete their missions . Cipher Nine eventually discovered Sazen was searching for Nasan Godera ' s Ultrawave Transmitter , a device that she hoped to use to control the rakghoul s and make them into her own personal army . Since Sazen was also hunting Doctor Ianna Cel , Lokin offered to be captured by Sazen in her stead by posing as Doctor Cel ' s assistant . Once taken to the Ultrawave Transmitter , he signalled his location to Cipher Nine . After Cipher Nine dealt with Sazen , the agent then discovered a Rakghoul savagely killing some armed Nikto , which soon transformed back into Doctor Lokin who explained that he freed himself to examine Sazen ' s laboratory . After handing the Ultrawave Transmitter to Cipher Nine , he promised to provide further explanation of his history once they had regrouped at the Imperial Command Center . Lokin explained that he was studying the Rakghouls for some time and his true goal on Taris was to review Sazen ' s stolen research .

While travelling with the agent , he scavenged data on the Rakghoul plague and conducted experiments on himself to further his research . Agents from Project Protean were scouting the safe houses of Doctor Lokin in order to eliminate him . This was because he was conducting his own research on the Rakghoul virus . One of their operatives and two genetically enhanced human agents were killed on such a mission by the safe house ' s booby traps and died in an explosion . This led to a period of investigation by Lokin who discovered the existence of the project and their involvement in Vector ' s Joining . Thus , he departed with Hyllus to deal with the matter . Both Lokin and Vector assaulted Project Protean ' s HQ and " interviewed " the woman in charge to gain answers . Lokin discovered why they desired his demise and how his research was used to further Project Protean and Vector had his files deleted and stopped further Killik experiments . In return for sparing their laboratory , Lokin became the new head of Project Protean . During the Eternal Empire ' s Conquest , the Agent went missing . Soon afterward , Lokin retired to a small plantation on Alderaan with his tamed rakghouls . Soon he got sick from his rakghoul disease , leaving him close to death , until he received aid from the Outlander and was recruited into their Alliance , dedicated to bringing an end to the Eternal Throne .
