East-1 was the designation, or callsign, for a human operative within the Corporate Tactical Forces of Preox-Morlana. During the time of the Imperial Era, East-1 was involved in an ambush on Ferrix that targeted Cassian Jeron Andor. East-1 attempted to eliminate Cassian Andor and Luthen Rael with a sniper rifle, but they evaded him amidst the urban environment. Subsequently, he saved Deputy Inspector Syril Karn following his capture by Andor, and also aided in the retrieval of the North Team after a landspeeder was detonated by Luthen Rael.
