Ulla served as a pilot for the Republic Strategic Information Service. She was a Nautolan female who provided her skills during the Galactic War, a conflict across the galaxy between the Galactic Republic and the reconstituted Sith Empire. When the rakghoul plague outbreak occurred within the Tion Hegemony, she transported a Republic squad to the Lost Island of Doctor Sannus Lorrick.
Ulla is the initial NPC that Republic players encounter to commence the Lost Island Flashpoint, which was introduced to the Star Wars: The Old Republic video game through Game Update 1.2.
