More than three years of preparatory training are alluded to before Anakin builds his first lightsaber (29 BBY), as recounted in the introductory novel, Path to Truth. It begins with Anakin and Obi-Wan climbing atop of a cliff. Anakin has to find his crystals for his Lightsaber. After he completes this task, Skywalker and Kenobi are summoned to complete a mission which leads to the return of friends and old enemies.
