Deerna held the position of Rodno's female romantic partner when Darth Vader tried to seize control of Kadril in the year 1 ABY.
Deerna, a member of the Kadrillian species, chose to live separately from the main Kadrillian population. A youthful scientist, Rodno, was responsible for Deerna's creation. Despite Rodno abandoning the traditional non-Nociv lifestyle, Deerna harbored significant skepticism regarding his capabilities.
During Father's final assault utilizing the Pacifog, Rodno risked his own well-being and sustained injuries to save Deerna's life.
Simultaneously, Leia, Del Quirz, and Chewbacca realized the immense value of Rodno's Vibro-crystal, which even provided protection against Father's Pacifog. After Rodno healed from his wounds, Deerna came to view him as a suitable companion.
