The Non-Canon Expert looks at how Palpatine never once wavered in his confidence that the Sith and dark side would ultimately gain power over the Jedi and light side, nor that the Galactic Republic could be weakened through the influence of the Sith, but then explains how a third necessary element envision by Darth Plagueis and Darth Sidious to achieve the Sith Grand Plan would cause difficulty for Palpatine to envision the successful completion of the Grand Plan in his lifetime. This is a Legends story for Darth Plagueis and Palpatine, as well as the political lineage of the Galactic Republic, with information primarily found within the Legends novel «Star Wars: Darth Plagueis.»
