The Carbonite Sith Army holocron represents a Sith holocron, having been pilfered from Jabba the Hutt by both Tyber Zann and Urai Fen. Fen speculated that the holocron was approximately 4000 years in age, suggesting that it originated around the time of the Great Sith War. To gain a deeper understanding of the artifact, they needed someone strong with the Force, leading them to seek out the Nightsister named Silri. At first, Silri only managed to reveal archaic star maps. Zann became dissatisfied and instructed Bossk to return the holocron to Thrawn, an act that enraged Silri. Later, when the Consortium's commanders arrived on Coruscant to obtain the access codes for the Emperor's vault, Silri, along with her [rancor](/article/rancor/legends] companion, Cuddles, managed to retrieve the lost artifact. Once Zann had successfully accessed the vaults, Silri decided to investigate the device independently, ultimately utilizing it to locate the Carbonite Sith Army.
