The Ductavis Holocron represented a holocron created by Biel Ductavis, the Grand Master who headed the Jedi Order and also held the position of Supreme Chancellor within the Galactic Republic after the Pius Dea Crusades. After Ductavis' death, this holocron was placed on the planet of Ossus, but was subsequently lost during the evacuation of Ossus due to the Cron Supernova.
Contained within the holocron were historical records detailing the early days of the Galactic Republic. Subsequent scholars speculated that the information within the holocron had the potential to reshape the understanding of galactic history and facilitate the recovery of the lost planets Had Abbadon, Lettow, and Tython.
