Daan, a Human woman, held the rank of Lieutenant in the Confederate Navy, serving during the era of the Clone Wars; her gender was female.
In approximately 21 BBY, Daan served as a member of the Starcrusher's personnel. During the operation involving the mock-Starcrusher, her fellow crew members abandoned her on the booby-trapped vessel, compelling Daan to collaborate with the Jedi to ensure her survival.
Daan provided assistance to the Jedi warriors by finding spacesuits and figuring out the coordinates for the real battleship's reactor core. Although the other crew members perished when the Starcrusher crashed into a star, Daan, along with the Jedi, managed to live through the disaster.
