Chronicle of a Lost Tradition

The Chronicle of a Lost Tradition was a Jedi holocron created during the Imperial era by members of the Order of the Old Tradition (also known as the "Remnantists"). This holocron contained the history and philosophies of the Order of the Old Tradition and also contained plans for the formation of a new Jedi Order.

History
A Remnantist elder created this holocron and stored it in a vault near their stronghold on Kashyyyk. A Mandalorian treasure hunter named Naastau, who had a history of hunting and selling Jedi artifacts, learned of the holocron's existence and traveled to Kashyyyk to infiltrate the vault. After overcoming some of the Wookiees and Jedi present, Naastau stole the holocron and left Kashyyyk. The holocron was eventually sold to members of the Invisible Market, who kept the holocron in storage for many years until it was sold to a Jedi who was disguised as an artifact dealer. This Jedi then turned the holocron over to Luke Skywalker, who drew inspiration from the holocron's contents while forming the New Jedi Order.
