Captain Wallace Fisk was a charismatic Imperial Security Bureau agent with the Investigations branch, and had also served in the Surveillance branch. Toward the end of the Galactic Civil War he was assigned to Demophon, an assignment he hoped would net him a promotion to lead a sector Investigations office. During the evacuation of Demophon prior to its sun going supernova, Fisk was the highest ranking Investigations officer remaining at the ISB Headquarters Office in Selkren. He took personal charge of seeing all prisoners off the planet and overseeing the evacuation of critical files from the ISB headquarters.
