I discovered something interesting about the cybernetic apparatus Palpatine was hooked up to in Rise of Skywalker. It is called the “Ommin Harness” and it used to be worn by an ancient Sith king. The name “Ommin” is a clear reference from Legends regarding a Sith sorcerer known as Ommin. Like Palpatine, Ommin’s power in the dark side of the Force was so great that it caused his body to decompose and fail. The only way Ommin could move and survive was to hook himself up to a cybernetic exoskeleton. I thought this reference was a nice touch that connects the new Canon with Legends.
