Not every Imperial Intelligence officer is privileged with a designation and number. The tens of thousands of Imperials who serve as the espionage agency's backbone have a variety of ranks and maintain the daily flow of information from hundreds of worlds to the Citadel.
The position of station chief is a vital, if often unrewarding, rank within the Intelligence hierarchy. Station chiefs are posted to planets by Keeper or the Watchers and tasked with maintaining order and monitoring the population. It's a station chief's responsibility to make sure suspicious activity is reported, to use his or her resources to contain local threats, and to support the Sith, the military and the Ministry of Logistics.
