Chronicle of Theramus

The Chronicle of Theramus, also known as the Theramusite Holocron, was an ancient holocron created by a Jedi Master known as Theramus, who lived during the time of Darth Desolous' war with the Galactic Republic. Theramus' holocron contained various pieces of information including lightsaber combat forms, profiles of various historic Jedi High Council members, and a crude record of the Sith Order's history. Sensing the end of his lifetime, Theramus constructed a vault on Sarapin which was protected by dormant security droids. Thousands of years later around the time of the Separatist Crisis, a Mandalorian treasure named Naastau traveled to the vault on Sarapin, who after defeating the security droids managed to acquire the holocron and turn it over to one of his employers.
