Cesi "Doc" Eirriss was a female Twi'lek pilot who served in the Alliance to Restore the Republic's Red Squadron prior to the Battle of Yavin. Around 0 BBY she accompanied Wedge Antilles, Biggs Darklighter and Jek Tono Porkins to Commenor to escort Nera Dantels and her badly-needed cargo of astromech droids to Yavin 4. Pursued by TIE Fighters shortly after leaving Commenor, Eirriss's ship was hit by debris from an exploding TIE solar panel, damaging her deflector shield generator and hyperdrive. Antilles ordered her to abandon ship, but Eirriss knew that a recovery would take away precious time from their escape and directed her X-wing into a collision course with the pursuing TIEs. Eirriss was killed when her ship was destroyed in the resulting collision, though the explosion eliminated a number of the Imperial starfighters and gave the other Rebels a chance to escape to hyperspace.
