Darth Plagueis (Powerstaark)

Darth Plagueis was a dark lord of the Sith and the master of Darth Sidious. Plagueis was obsessed with finding a way to cheat death and in addition he was the only known practitioner of Midi-chlorian manipulation which he used to create Anakin Skywalker. It is unconfirmed it he created Anakin intentionally or if it was an accidental result of one of his experiments. Plagueis was eventually killed in a duel with his apprentice Darth Sidious who replaced him as dark lord of the Sith.

Training Darth Sidious

 * "Tell me what you regard as your greatest strength, so I will know how best to undermine you; tell me your greatest fear, so I will know what I must force you to face; tell me what you cherish most, so I will know what to take from you; and tell me what you crave, so that I might deny you."


 * ―Darth Plagueis to Darth Sidious

Nothing about Darth Plagueis' early life is known. Suffice it to say, Plagueis became a very powerful Sith Lord with immense knowledge of the dark side of the Force. He eventually discovered Palpatine on Naboo and trained him in the ways of the Sith.

Palpatine learned from Plagueis over the course of decades, during which Plagueis taught his apprentice almost everything he knew to prevent the power he had amassed from being lost forever. During Sidious' training, Plagueis gave his apprentice access to his Sith holocrons. Plagueis' lessons involved forcing Sidious to face his fears, denying him pleasures, and taking from him the things he loved. He taught Sidious that emotions such as envy and hatred, though necessary to master the dark side, were simply means to the end of casting aside usual notions of morality for a greater goal. Plagueis also lectured his apprentice on the means of taking power, with the eventual goal of control over the galaxy.
