He was reassigned to Alderaan due to diplomatic manpower needs with House of Thul . He served ably until his encounter with the Killik species and subsequent " Joiner " transformation . According to Doctor Eckard Lokin , Project Protean arranged Vector ' s meeting with the Killiks so they could study the Joining . As a joiner , he serves as the Oroboro Nest ' s Dawn Herald : a warrior and emissary of the nest , one who confronts the unknown . As Herald , Vector was more than a typical joiner and retains a sense of individuality . Funding for the Eagle ’ s terrorist network was traced to Alderaan ; Cipher Nine was sent to identify and eliminate the source . The Imperial Agent met the Joiner contact Vector Hyllus and gained entry into House Cortess despite the initial hostile actions of Baroness Chay Cortess .

During this time , it was discovered that Baroness Cortess herself was also aiding the terrorists . The Imperial attempted to confront Chay Cortess , however , she instructed her guards to bar entry to the agent . This led to Vector Hyllus bringing in Killik support where they damaged the Cortess shield generator in the Glarus Valley .

When he returned , he reported he was unable to find any of the lost Killiks and could only infer that they eventually separated into a thousand nests ; each going their own way . A few moments later , he was contacted by another Dawn Herald : Daizanna of the Iesei Nest . Both Killik Nests rejoiced at finding their lost kin and invited the Agent to join in their celebration . Having discovered the resources and benefits of the vast Killik civilizations across the galaxy , Vector proposed to the Imperial Diplomatic Service a Killik - Imperial Alliance . Unfortunately , the Diplomatic Service ignored his report . An old colleague , Falner Oeth , reached out to Vector and proposed an alliance . In exchange for Falner ' s promise of future support for his Killik alliance proposal , Vector and his Killiks would use their resources to do dirty jobs for him and expand his influence .

After conferring with various ambassadors of the Sith Empire , the Diplomatic Service had finally agreed to an official treaty with the Killiks . At the summit to legitimize the treaty , the proceedings were sabotaged with a bomb that led to the death of Daizanna . Falnar Oeth takes responsibility for the bomb and released a public speech decrying the Killik - Imperial Alliance . Even so , the Imperials continued to legitimize the Killik - Imperial treaty and the Imperial - Killik alliance was made official . The Killik Nests offered Vector the position of Dawn Herald of all Killik Nests but refused the position as he felt his priority was being the Agent ' s companion and covert assault operative .
