The holocron was built by members of the Sith Empire and contained three gatekeepers: Dargous Tanmoul, a Sith battlemaster; Sansin Koriss, a Sith apprentice; and Bavik Vannor, a fallen Human Jedi. During the Great Hyperspace War, the Sith Valik Kodank took it with her to the Temple of Pain in the Tascollan Nebula. She kept it inside a small room, where it was suspended in a repulsorfield. A group of New Republic agents traveled to the temple during the Galactic Civil War and they found and examined the holocron.
