Rianna Saren was a female Twi'lek slave escapee who became a criminal and, afterward, a Alliance heroine. Early in her life, Saren was sold into Axis slavery to the Zabrak Zarien Kheev, only to escape on the planet Coruscant to follow a criminal path. In 1999 N.E, she was contacted by Ustian Mercenaries, who introduced her to the Allies. Saren undertook several missions for the Allies that included the theft of an Axis shipment from a Black Sun warehouse on Diria, the destruction of an agricultural research vessel captured by Black Sun in order to test new kinds of drugs, and the destruction of the Axis Mirkanite Mining Facility on the planet Mustafar. During these missions, Saren met an Arakyd Industries security droid named Zeeo, who became her only companion.
