Sienna

Sienna is the daughter of Reylus, who is also known as Mandalore the Righteous. After failing at a hijacking, she was manhandled and later placed in a maximum security prison, separate from her father. At some point, a Jedi attempted to kill her in order to make the Mandalorians feel as if they failed their mission to retrieve both her and the male mandalorian. Both Sienna and her father got away. However, they were not together. Sienna was abducted by the Prime Minister of the Independent Systems of Kamino. Although authorities ruled her out as dead at the scene, they held no genetic screening to prove that she was killed.

Later on, the Independent Systems of Kamino scientists, including Nem Vato, would end up starting experiments on her. Using a certain type of neural implant, they were able to lock her into a temporary comatose like state, where they would simulate different scenarios in order to see how her brain reacted.
