Fau-Kes was a Cathar male agent in the Republic Strategic Information Service, the intelligence branch of the Galactic Republic, during the Cold War against the Sith Empire. Fau-Kes was one of several SIS agents sent to the planet Taris to help a young Jedi Knight locate the missing scientist Nasan Godera. Although the agents were unable to locate Godera or the Jedi in the field, the Knight was successful in retrieving the doctor, and Fau-Kes escorted Godera back to the Republic's capital of Coruscant.
