The Lack of Sith Lords

Under Palpatine's Galactic Empire, people were discouraged from believing in the Force and the Jedi Order. However, it was not just the Jedi who suffered. All Force-sensitives were targeted. Some examples included the Quermians, who were accused of sending seditious thoughts into the minds of others. The Iktotchi were attacked due to their telepathic abilities, which were said to be drawn from the Force. Despite the established anti-Jediism of the New Order, many in the Imperial government were aware that Emperor Palpatine and Darth Vader were Force users, and a few even knew that they were Sith Lords. Palpatine also commissioned a loose organization of loyal Darksiders called the Dark Side Adepts as a replacement for the now abolished Jedi Order and to make up for the lack of Sith Lords to do his bidding. The lack of Sith Lords is because of Darth Bane, who created the Rule of Two, which says that there can only be two Sith at any one time.
