Bane's training in and ascension to the Sith is detailed in both "Path of Destruction" and "Jedi vs. Sith". As a student, he meets a new apprentice (and former Jedi) named Githany, who secretly plans to use him to bring down Sirak. Githany reestablishes his connection to the dark side by showing him in secret what the Sith Lords are teaching her. Most importantly, and to the dismay of the instructors, Bane studies tomes from the Golden Age of the Sith. He soon realizes that the Brotherhood's teachings are incomplete.
