As Kamino’s chief medical scientist, Nala Se played a key role in engineering the Grand Army of the Republic – and worked to protect the army’s secrets. She cared for clones injured on the battlefield, supervising their rehabilitation even when Separatist attacks threatened her own life as well as the lives of soldiers. But she had a ruthless side as well, insisting to Jedi General Shaak Ti that the clones were Kaminoan property to be disposed of as their creators saw fit. Nala Se knew of the bio-chips implanted in the clones to ensure that they obeyed protocols such as Order 66. Obeying the orders of Count Dooku – whom she knew as Lord Tyranus – she sought to keep these implants secret from the Jedi.
