Hazeen was a spy of the Neimoidian species, working for the Imperial Intelligence of the Imperial regime during the Galactic War that pitted the Sith Empire, which had returned to power, against the Galactic Republic.
Hazeen successfully infiltrated the rebel forces of Corellia as they plotted an attack on the occupying forces during the invasion of Corellia by the Empire. Hazeen then used the probe droid known as G-05, which was located near Coronet Spaceport, to inform the Imperial forces. A strike team was dispatched as a result to prevent the assault.
