Vu Nin, originally from Alderaan, served as a trooper for the Rebel Alliance. However, she was not on Alderaan when the first Death Star obliterated it. Upon learning of her homeworld's demise, she sought a role within the Special Forces. After finishing her Infiltrator training, she asked to be moved to the Alderaanian Death Legion. However, she was instead placed in Taskforce Shen. Ultimately, she rose to the rank of First Lieutenant, functioning as second-in-command to Mart Stevez.
