Adas's holocron

Adas' holocron was the original Sith holocron, made by King Adas around 27,000 BBY. He learned how to crate the holocron from the Rakata who had come to conquer Korriban, and whom he had driven off.

Around 3,990 BBY, it was uncovered by Queen Amanoa of Onderon, who learned all the stored secrets. The holocron was then passed to her apprentice Novar to teach Sith initiates. The Gatekeeper of Adas's holocron, however, had an unique personality that it could turn down the user's request or even threaten its user.

At one point, Palpatine sent Carnor Jax's father to rerieve the holocron, killing him when he failed. It eventually found its way into House Pelagia's holocron library and subsequently liberated by Sir Nevil Tritum of the Mecrosa Order during the Great Jedi Purge. Following the Battle of Endor the Order gave the holocron to Lumiya.
