He was the most powerful Sith lord who ever lived. But could he be the only one who never died?  “Did you ever hear the Tragedy of Darth Plagueis the Wise? It’s a Sith legend. Darth Plagueis was a Dark Lord of the Sith, so powerful and so wise that he could use the Force to influence the midi-chlorians to create life. He had such a knowledge of the dark side that he could even keep the ones he cared about from dying.” —Supreme Chancellor Palpatine, Star Wars: Episode III Revenge of the Sith  Darth Plagueis: one of the most brilliant Sith Lords who ever lived.

For like no other disciple of the dark side, Darth Plagueis learns to command the ultimate power . . . over life and death.  Darth Sidious: Plagueis’s chosen apprentice. Under the guidance of his Master, he secretly studies the ways of the Sith, while publicly rising to power in the galactic government, first as Senator, then as Chancellor, and eventually as Emperor.  Darth Plagueis and Darth Sidious, Master and acolyte, target the galaxy for domination—and the Jedi Order for annihilation.
