During the time of the Cold War, the operation titled Operation Silverplate revealed that the planet of Alderaan was the source of finances for Eagle's terrorist organization, which was an anti-Sith Empire cell. Subsequently, Agent Cipher Nine was dispatched to find and neutralize the funding origin. Vector Hyllus, a member of the Imperial Diplomatic Service, was selected to aid the agent in this task.
Cipher Nine, along with Hyllus, determined that the primary financial backers of the terrorist network were the local negotiator Denri Ayl and Baroness Chay Cortess. Nevertheless, House Cortess itself was not implicated, although the Sith Empire implemented necessary reactions and safeguards. Following the successful completion of the operation, Vector Hyllus transitioned into an Imperial asset, receiving a transfer from the Diplomatic Service.
