[Source] An ancient Sith tome was kept at the academy on the ancestral Sith homeworld of Dromund Kaas. The manuscript was more than 10,000 years old by 3954 BBY, and was dated to the time of the arrival of the first Dark Jedi on Dromund Kaas and their interactions with the native Sith species. Considered one of the academy's greatest treasures, the tome was the only physical artifact the Sith Lord Scourge had seen during his time there as an apprentice.
