Eventually, however, around 0 BBY, the secondary holocron that started off the series of clues was discovered by an archaeological team on Thule. Palpatine, intrigued by this new discovery, ordered Darth Vader himself to study this, aroused by the possibility of locating the legendary Atrum. However, before he could arrive, agents from the Rebel Alliance and Black Sun turned up the site of the discovery, both intent on getting away with the holocron. After a fierce battle, the rebels made off with the holocron, with the Black Sun minions in hot pursuit. Unbeknownst to both of them, the archaeologists had made copies of the etchings on the Holocron, so Vader had something to work from when he arrived.
