In an effort to steer the conversation back to Star Wars, let's not forget Dr Evezan's special project:
the Decraniated!
We were shown glimpses of these pitiful cyborgs in both
Rogue One and
Solo, but the truth of their sorry state of existence was revealed in books.
Evazan's work is nothing short of a nightmare. His Decraniation process strips a subject of all free will, turning them into living droids carrying out the whims of their owners. It is a crime far worse than slavery, for at least slaves can be freed. The only freedom that awaits the Decraniated is the release of death.
