Darth Revan's Sith Holocron

Constructed by the Dark Lord of the Sith Darth Revan during the Jedi Civil War, Darth Revan's Sith Holocron, also referred to as the Holocron of Darth Revan, or simply Revan's Holocron, contained the Sith Lord's teachings on the dark side of the Force, and his knowledge of ancient Sith rituals. It included instructions on how to use the Force power known as the thought bomb, and the lessons from the Holocron focused on the user coveting the dark side and the importance of a Sith Master training one apprentice at a time. Following Darth Revan's redemption and the end of the Jedi Civil War, the Sith holocron remained hidden within the Temple of the Ancients on the planet Lehon.

Three millennia later, the Sith Lord Darth Bane rediscovered Darth Revan's Holocron inside the Rakatan temple and extensively studied the teachings contained inside. Bane copied the Holocron's contents and destroyed the artifact when its power source ceased to work. Bane went on to purge the ruling Sith regime, creating his own Sith Order using the teachings from Darth Revan's Holocron. Bane later transcribed Darth Revan's knowledge into the Telos Holocron, which was eventually studied by the Sith Lord Darth Sidious and later the New Jedi Order.
