Darth Revan ' s Sith Holocron Constructed by the Dark Lord of the Sith Revan during the Jedi Civil War , Darth Revan ' s Sith Holocron , also referred to as the Holocron of Darth Revan , 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 Rakata Prime . 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 . Properties . Darth Revan ' s Sith Holocron , also known as the Holocron of Darth Revan , was created by Dark Lord of the Sith Revan in the shape of a four - sided pyramid . The Holocron resembled the Temple of the Ancients , an ancient Rakata n structure on the planet Rakata Prime . The Sith Lord ' s Holocron was slightly larger than a Human ' s hand and , unlike most Sith holocrons , was adorned with only a few Sith symbols . The Holocron ' s gatekeeper was an avatar of Darth Revan , and the artifact was powered by a crystal that channeled energy from the Force . However , the crystal was unstable , and the more the Holocron was used , the less stable the crystal became . Contents . Darth Revan ' s Holocron contained the Sith Lord ' s teachings and beliefs on both Sith philosophy and the dark side of the Force . The Holocron also explained the purpose and nature of ancient Sith rituals , some of which were considered dangerous for even a Sith Master to attempt . One of the rituals taught by Darth Revan ' s Holocron was the thought bomb ; the ancient Sith used the Force to create a power sphere , and when the thought bomb was detonated , the bodies of Force - sensitive individuals were destroyed , with their spirits trapped inside a vacuum created at the detonation ' s focal point . In addition , the Holocron detailed the teachings of the individual Zelashiel the Blasphemer , which related to the use of the power drain life . The Holocron also instructed a student how to counter and nullify poisons with the Force . Darth Revan ' s instructions in the Holocron taught that an individual who used the dark side was also obligated to serve it , and that understanding this principle meant that the person comprehended the inherent philosophy of the Sith . The Holocron stated that the dark side offered a person power for its own sake and encouraged the learner to covet power and seek the dark side ' s strength with no reservations . It further taught that the Force would transform the user and recommended that the user embrace the change that came with accepting the dark side ' s power , arguing that the Jedi were limited in their accomplishments due to the fact that they focused on controlling the Force ' s transformation of the individual . Darth Revan ' s teachings maintained that true power came only to people who fully accepted the Force ' s transformation of them , claiming that traits such as loyalty , mercy , and compassion prevented an individual from claiming what was theirs . The Holocron taught that an individual who accepted the dark side ' s power also had to accept the challenge in retaining their hold on that power . It stated that the dark side ' s nature of rivalry and strife was not only the Sith ' s strength , but that these traits were also the Order ' s weakness . Darth Revan ' s avatar opined that a Sith Master who trained more than one apprentice in the dark side was a fool , stating that multiple students would combine their efforts and overthrow the Master . As such , the teachings advised a Master to instruct only one apprentice at a time , lest the Master become overwhelmed by the weaker students who allied to defeat the Master . Darth Revan taught that the Sith should only have one Dark Lord of the Sith , who embodied the dark side ' s strength and power , and that when the Dark Lord grew weak a challenger needed to seize the mantle from the reigning Dark Lord . The Holocron theorized that the weak were meant to serve under the rule of stronger individuals . After the Holocron ' s user went through all of its teachings , Darth Revan informed the learner that the lessons were finished and instructed the individual to take the instructions he had imparted to the student and use them well . History . In 3959 BBY , the former Jedi Knight Revan declared himself the new Dark Lord of the Sith , with his friend and fellow former Jedi Knight Malak becoming Revan ' s Sith apprentice . The two Sith Lords , who both had taken the " Darth " title , returned from the Unknown Regions at the head of a new Sith Empire and declared war on the Jedi Council and the Galactic Republic , initiating the Jedi Civil War . During Darth Revan ' s reign as the Dark Lord , he constructed a holocron and recorded his views on Sith philosophy and the dark side . Darth Revan hid the Holocron behind a stone in a wall located behind a Rakatan computer in the Temple of the Ancients on Rakata Prime , a world he and Malak discovered during their search for the ancient Rakatan space station called the Star Forge . Two years into the war , Revan was captured by the Jedi Order , and after being retrained in the Jedi ways , redeemed himself by vanquishing Malak and ending the war . After the war ' s final battle , Jedi and Republic forces went through the temple and removed all of the Sith artifacts except for Darth Revan ' s Holocron , which remained hidden in the Temple ' s lower levels . Almost three millennia later , near the end of the New Sith Wars , the Sith Lord Darth Bane traveled to Rakata Prime , which had since been renamed Lehon , in search of teachings with which he could destroy the existing Sith regime , the Brotherhood of Darkness . Bane explored the lower levels of the Temple of the Ancients for any dark side artifact s , eventually coming to the room where the Holocron was hidden . While in the room , he sensed the power of the Holocron , which was still hidden behind the stone in the wall behind the computer . After using the Force to remove the stone , Bane retrieved the Holocron and activated it , revealing an avatar of Darth Revan . As Darth Revan ' s image instructed Bane , the Sith Lord copied the artifact ' s lessons on sheaves of flimsi so that he could study the teachings at a later time . Eventually the Holocron ' s power crystal began to fail due to Bane ' s continued use of the device . After Darth Revan ' s image imparted the Holocron ' s final lessons to Bane , the device ceased to work . Bane used the Force to destroy the device , discarding the object as Darth Revan had taught him . Bane then purged the Brotherhood of Darkness and created his own Sith Order using the teachings from Darth Revan ' s Holocron . After establishing the Rule of Two , Darth Bane transferred Darth Revan ' s teachings that he copied on Lehon into the Telos Holocron . Darth Revan ' s lessons on the dark side of the Force remained in the Telos Holocron and were eventually studied by the Dark Lord of the Sith Darth Sidious . Both the Telos Holocron and Darth Revan ' s teachings were later recovered and examined by the New Jedi Order in 40 ABY . Behind the scenes . Darth Revan ' s Sith Holocron was introduced in the novel " " , written by Drew Karpyshyn , and was used as a major plot device for the titular character to destroy the Brotherhood of Darkness and establish the Sith Order ' s Rule of Two . The device was first identified as Darth Revan ' s Sith Holocron in " " . According to the guide , Darth Bane discovered and studied the Holocron on the Sith tombworld Korriban , which contradicts the information given in " Path of Destruction " . The Holocron was later mentioned in Darth Bane ' s entry in " The Complete Star Wars Encyclopedia " and was also featured in the reference guide " " .
