Years after the Galactic Empire's rise to power, the mother of Zarro left the planet Andelm IV aboard a starship. Zarro was left with her father, Arrax, and the two worked in the Andelm beetle caverns. Shortly after the Battle of Yavin, Zarro escaped the caverns, encountering the Wookiee Chewbacca. Desperate for the Wookiee's help, Zarro begged him not to leave, bringing up the story of her mother leaving. Eventually the Wookiee complied and helped the girl.
