Ductavis Holocron

The Ductavis Holocron was a holocron that was constructed by Grand Master Biel Ductavis, a leader of the Jedi Order who served as the Supreme Chancellor of the Galactic Republic in the aftermath of the Pius Dea Crusades. Following Ductavis' death, the holocron was stored on the planet Ossus, where it was lost following the evacuation of Ossus as a result of the Cron Supernova.

The holocron contained accounts of the ancient history of the Galactic Republic. Later researchers believed that the contents of the holocron could re-write galactic history and lead to the rediscovery of the lost worlds of Had Abbadon, Lettow and Tython.
