Trefaren, an Imperial Admiral, found himself stationed on Corellia around 3 BBY. The admiral requested that Bria Tharen join him at a Corellian government reception for Imperial officers. Little did Trefaren realize, Bria was actually a Rebel operative who had successfully infiltrated the Imperial base; she was exploiting the admiral to uncover details about the Galactic Empire's latest acquisitions in weaponry and starships.
