In 3666 BBY, during the time of the Great Galactic War between the Galactic Republic and the Sith Empire, Rehanna met and fell in love with a Jedi Padawan named Nomar Organa, a member from the House Organa. However, their relationship was short when Nomar broke off his marriage and returned to serve the Jedi Order, leaving Rehanna heart-broken.
Twenty-three years later, during the Cold War, Rehanna remained within the House Rist until she encountered a Sith Inquisitor named Kallig, who was searching for an artifact of Tulak Hord. Rehanna engaged the apprentice, but she proved was no match for the Sith. After contacting her lover into bringing him into a trap, Kallig executed her.
