After helping the Qrephs' hired Mandalorians capture Han Solo, the brothers left her to die aboard their mobile headquarters, the Ormni, by having her wither away from lack of feeding enzymes needed to sustain her. She was saved by Luke Skywalker and Leia Organa Solo, and despite admitting her heinous treachery to the refinery, she was still accepted as an ally against the Qrephs, if only so that she could get her feeding enzymes at Base Prime, where she was created.
Following the deaths of the Qrephs and the destruction of Base Prime, Yus was fated to stand trial before the Jedi Council on the planet Shedu Maad for her crimes.
