Immortality/Legends

Immortality is the state of a biological being living indefientely for a seemingly infinite or indeterminant amount if time. This state was the goal of many Sith Lords throughout history, and at least one Jedi; though the former was more interested due to the Sith's tendancies to fear death and the unknown, and the ultimate sith goals of power, control and glorification of self.

History

 * The Emperor Vitiate was the first Sith Lord to have successfully gained immortality by draining the life forces of an entire world to ensure his immortality.


 * Darth Andeddu created the Transfer essence which essentially is a form of immortality, and was able to return to life in 137 ABY when he drained his servant's spirit back into his corpse.


 * Darth Sion achieved the ability to rise from near-fatal injuries through sheer hatred. However, it left him a broken shell of accumulated injuries and wounds.


 * Darth Drear thought to cheat death by infecting himself with the sickness and then feasting on the heart of a Jedi, having the midi-chlorians stabilize his condition. This method failed, but only because, Drear could not find a victim strong enough in the Force, so it is possible that this method might've worked, if executed correctly.


 * Darth Tenebrous achieved a form of immortality that backfired horribly on him. By converting his consciousness into midi-chlorians, he was forced to live his final moments for all eternity in a time loop.


 * Darth Plagueis supposedly discovered immortality through Midi-chlorian manipulation, but this is unconfirmed.


 * Qui-Gon Jinn learned to manifest as a Force ghost after death and retain consciousness in the Force.


 * Palpatine cheated death by creating clones of himself.


 * Darth Simi kept herself alive for thousands of years by sacrificing young Jedi to the dark side of the Force.


 * Dr. Cornelius Evazan invented a successful Reanimation Serum.


 * Darth Krayt possibly could be immortal due to bringing himself back to life once.
