Without a doubt, the Sith Empire is the most secretive of the two galactic powers present in The Old Republic, certainly more so than its counterpart, the Galactic Republic. This is most evident with the establishment of the Imperial Intelligence agency and the deployment of its various agents around the galaxy, keeping tabs on its enemies and allies alike. While the Imperial Intelligence is shrouded in secrets and shadow, there is one man known to be a prevalent figure within Intelligence. But even still, the man known as Keeper is still a mystery. 

The only things known about Keeper is his codename and his secrecy. Most of his past and his true identity are unknown. But it is known that Keeper is the ultimate spymaster within the Empire, and the head of the Operations Division within Imperial Intelligence. He had knowledge of, and approved of, every infiltration into enemy territory, every agent deployed by Intelligence, and every execution of any enemies to the state. Keeper was reputed to be merciless as well as ruthless, easily approving executions of both enemies of the state and Intelligence agents he deemed weak or inefficient. Knowing he could be easily replaced if he failed, Keeper knew when to obey orders and when to seize the initiative for himself.
