- "Curse that fool Dreypa and his blasted Oubliette! What use is it to live through the millennia if one is trapped inside a box?"
- ―Karness Muur
An oubliette was a type of stasis casket that was used by the Sith. Oubliettes had an ability to keep those inside them alive for thousands of years.
The Sith Lord Remulus Dreypa created an oubliette in order to imprison and torture his rival Karness Muur, and to contain the hypnotic influence of the Muur Talisman. In 3963 BBY, this oubliette came into the possession of Mandalorian researcher Pulsipher, who transported it to his laboratories on the ice world of Jebble. During the Rakghoul plague, Pulsipher threatened to inter Zayne Carrick in the Oubliette in order to coerce him into revealing the powers of the Muur Talisman. After Pulsipher's death, Zayne Carrick suggested that Celeste Morne could be imprisoned in the Oubliette until the Jedi Covenant determined some means to nullify the Talisman's interference with her mind. When the walls of the Oubliette cut off the Talisman's contact with the outside world, the Rakghouls were freed from Morne's control and turned upon each other.
Even as Carrick and his allies fled Jebble in the Moomo Williwaw, Cassus Fett arrived at Jebble with a Mandalorian fleet. (Carrick had previously alerted Fett to the danger of the Talisman via a transmitter on Jebble.) Over Carrick's desperate pleas, Fett bombarded Jebble with nuclear missiles. Carrick and company were forced to assume that Celeste Morne had perished, and they departed for Odryn. Unbeknownst to the Jedi or the Mandalorians, the Oubliette had, in fact, survived intact. It settled to the bottom of Jebble's newly-melted seas.
Several years later, in 3956 BBY, Darth Glovoc carried an oubliette aboard his flagship, the Dying Sun, when he traveled in it to the Luire system, to investigate the planet Nyriaan. However, the Dying Sun was attacked and crashed onto the world, leaving Glovoc and his surviving crew members stranded there. Through the use of his oubliette, the Dark Lord placed himself into suspended animation. Initially, Glovoc would limit these slumbers to around one hundred years, awaking briefly to gauge the progress of his people before returning to the oubliette. While in perpetual stasis, his depraved followers began to idolize him as a sleeping god, labeling him "the Dying Sun". To show their devotion, Glovoc's followers would often sacrifice inhabitants of the planet at the feet of his oubliette.
Roughly fourteen hundred years before the Battle of Yavin—nearly three thousand years after its submersion in the seas of Jebble—Dreypa's Oubliette was discovered by ice miners. Although the miners were unable to open the casket or even ascertain its contents, they assumed that such a well-protected treasure must be extremely valuable. One miner killed his companions and stole the artifact for himself.
Over the following centuries, the Oubliette changed ownership many times and became known to Galactic antique dealers as the Jebble Box. According to legend, the Box contained a secret treasure of the Jedi Order. As a result, the Oubliette was generally sold quickly and furtively, lest the Jedi interfere with the transactions in their quest to reclaim their valuables. The mystery of the Box's contents increased its price during each successive purchase. Several years before Palpatine's declaration of the Galactic Empire, the Chubbits of Aridus fought a war for possession of the Jebble Box.
In 19 BBY, the crew of the Uhumele located the Jebble Box on a battlefield on Aridus. Ishi Tib crime lord Haka Hai agreed to Captain Schurk-Heren's requested price for the Jebble Box. Before departing to Mimban for the sale, Heren took the precaution of secreting the Box in the ice rings of a gas planet. As Heren had expected, Hai attempted to steal the Box without paying. The result was a three-ways firefight between Hai's enforcers, the crew of the Uhumele, and Lumbra, a traitor within Hai's own organization. Lumbra ultimately acquired the Jebble Box, only to discover that it was, in fact, a counterfeit containing an armed bomb. The explosion of the bomb killed Lumbra's ally Gamy and crippled his vessel.
After escaping the prisons of Haka Hai, Schurk-Heren located another, more reputable buyer: historian Fane Peturri. Although Heren was confident that Peturri had no criminal ties, the scholar betrayed the crew of the Uhumele to Darth Vader.
Peturri analyzed the Jebble Box and located a recording made by Marn Hierogryph some four thousand years earlier. Unable to corroborate Hierogryph's reference to "Lord Dreypa's Oubliette" with any contemporary archaeological sources, Peturri concluded that the Box was a pre-Republic artifact.
Peturri remained skeptical of the Oubliette's ability to preserve life for thousands of years, but despite his request to study the casket further, Vader opened it—revealing a perfectly healthy Celeste Morne. Upon Celeste's revival she and Vader engaged in a duel in which Celeste gained the upper hand when she gave into the power of the Muur Talisman and transformed the surrounding Humans into Rakghouls. After Vader retreated she ordered the Rakghouls to destroy the Oubliette.
In 137 ABY, the Sith Lord Darth Vurik attempted to locate the sleeping Darth Glovoc and the oubliette in which he was contained. However, while Vurik was being distracted by a group of Jedi, Glovoc's Sith followers moved the casket to a hidden location.
