Sadvo was cast out of the Jedi Order, along with a fellow Padawan, for using the Jedi Archives to practice the Dark Side.
Sadvo took up a life on Alderaan as a Nerf farmer with his wife Lania. The two had twins and named them Epin and Rena. Sadvo acted extremely cruelly toward his son Epin, tasking him with doing both his and his sister Rena's chores. He favored Rena over Epin, and would often beating him, with the justification of teaching Epin how to be a man.
One afternoon, after making a delivery to Aldera Palace, Sadvo questioned Epin as to his interest in Princess Leia. When Epin responded excitedly, stating he liked being around her, Sadvo beat Epin and kicked him down a hill.
