Book of Sith: Secrets from the Dark Side (Star Wars)

The Sith have existed in the galaxy for centuries, lurking, waiting for their chance to seize control. In his quest for domination, Darth Sidious tracked down five pivotal Sith texts written by his most powerful predecessors. Then, drawing on the knowledge within the compiled pages, he wrote a sixth text - his own manifesto. Together, these documents shed light on the philosophy, achievements, and failures of the Sith Order.
