The Sith book of offerings and rituals was allegedly a book detailing the religious ceremonies of the Sith. During his search for details regarding his mother, Padmé Amidala, between 16 ABY and 17 ABY, Jedi Master Luke Skywalker noticed an ad for it. This ad was located within a courtesy cab that was run by the Galactic Archives, a small store situated in Trader's Plaza, Talos spaceport, on the planet Atzerri. This cab transported passengers to the primary distribution center for merchant's. The advertisement also featured the H'kig book of laws, Principles of Power, and a publication claiming to reveal the secrets of creating group minds similar to those of the Bilar species. The shop offered a discount for buying three or more books. Skywalker believed these advertised books were likely fake.
Shield of Lies, the second book in The Black Fleet Crisis trilogy, mentions the Sith book of offerings and rituals. Michael P. Kube-McDowell wrote the novel, which came out in 1996.
