- "To cheat death is a power only one has achieved, but, if we work together, I know we can discover the secret."
- ―Darth Sidious, to Anakin Skywalker
Immortality was a state in which a living being could live without ever dying. Darth Plagueis, a Sith Lord in the years prior to the Clone Wars, lusted for immortality. According to his apprentice, Darth Sidious, Plagueis manipulated the midi-chlorians to both create life and seek immortality. Those who followed the light side of the Force and had the appropriate training could achieve a form of immortality by retaining their consciousness after their physical deaths.
