"They made it out! Bola and Uthril and Nug, they escaped in the confusion!"
Uli Zhensi[src]

Uthril was an individual working as a mechanic for the Sith Empire's Project Threshold on Nar Shaddaa during the Cold War. Together with Uli Zhensi, Bola and Nug, Uthril became disgusted with the Empire's torture techniques and tried to sabotage the project. However, their plan was discovered and only Uli managed to escape. He later recruited a Galactic Republic citizen to finish their work and destroy the project, the task that helped Uthril and the others escape in the confusion.
