Sorin was a Human female Moff of the resurgent Sith Empire during the Galactic War. In 3642 BBY she was with fellow Moffs Ganthus and Talor onboard the treasury ship King's Ransom when it was boarded by a group of thiefs including the Voidhound. The smuggler found the Moffs conversing in the vaults on the ship, when Admiral Harridax Kirill opened fire on the ship with the intention to kill everyone on board. Sorin and other Moffs perished, but the thiefs escaped.
