Kay Tallon was a Human woman and the spouse of Adar Tallon.
The famed Clone Wars hero and subsequent fugitive from the Galactic Empire, Adar Tallon, staged his demise and sought refuge on Tatooine. It was there that he encountered Kay, whom he later wed. Tallon's accumulated savings enabled him to employ two servants, Morr and Cala Wenn, along with a majordomo droid identified as LN-26.
Following a period of cohabitation with Adar, a contingent of bounty hunters arrived, seeking his capture. Despite receiving assistance from allies like Vytor Shrike, Jungen, and Quist in his defense, the veteran commander determined that his safety on Tatooine was compromised, particularly after Quist's betrayal and the presence of Rebel operatives assigned to safeguard him. Consequently, Adar Tallon resolved to depart Tatooine and enlist in the Rebel Alliance. Kay and LN-26 accompanied him on this journey.
Subsequently, Tallon assumed the role of commanding officer over a small fleet, with the cruiser Silent Water serving as its flagship.
