QT-KT was present during the briefing of the Mission to steal a Separatist encryption module alongside her master. She was upgraded by the Parwan doctor Gubacher to have a controlled, hovering super magnet to use. In the vault she used the magnet to gather and disarm the swarm mines.
After Aayla Secura was killed during Order 66, QT went to Ryloth to live with Loris Cona, a friend of her previous master.
