Jebble

Jebble, a frozen planet with at least one moon, was situated along the Mandalorian Road in the Ojoster sector of the Outer Rim, within the system bearing the same name. The planet's surface was almost entirely covered in ice, forming immense peaks interspersed with expansive, frozen plains. Consequently, Jebble's climate was extremely cold. However, the planet experienced a rapid environmental shift following the bombing by Cassus Fett, the Mandalorian strategist, in 3963 BBY. Fett's bombardment caused widespread flooding, leaving only the tallest peaks visible above the planet-wide sea. Nevertheless, the world gradually regained its original icy terrain over several millennia following the bombings.

Jebble, together with Tarnith, Vanquo, and Suurja, functioned as a resource provider for Taris, the nearby ecumenopolis, a densely populated planet and a business hub in that region of the Outer Rim. In 3964 BBY, this proximity became a threat to Jebble as it found itself on the front lines of the emerging war between the Galactic Republic and the Mandalorian Neo-Crusaders. After a lengthy campaign to conquer unaligned worlds in the Outer Rim, the Mandalorians began to encroach upon Republic territory, specifically threatening Taris, which had become a full Republic member, and its resource worlds, including Jebble. The Republic Navy responded by organizing a security cordon known as the Jebble-Vanquo-Tarnith line, with Jebble as one of the key worlds. This line saw intense combat in the early stages of the war. The constant battles led many of Jebble's inhabitants to flee to nearby planets, including the mining world of Vanquo. The stalemate was broken when a massacre on Taris caused social order to collapse and the Jedi presence to be removed. Mandalore the Ultimate interpreted this as a signal to launch a full-scale attack on the planet. The Jebble-Vanquo-Tarnith line quickly proved indefensible, and the Mandalorians besieged and conquered Taris without significant Republic resistance in 3963 BBY.

Shortly after, the Mandalorians turned their attention to Jebble, which they also conquered and transformed into a regional power center in the Outer Rim. The Mandalorians repurposed Jebble's Ice Citadel into a war forge and a laboratory for Pulsipher, a leading Mandalorian scientist studying the source of the Jedi's powers. In addition to being a site for Mandalorian ice mining, Jebble gained importance as a staging area for thousands of Mandalorian recruits being organized and prepared for a planned raid on Alderaan, a pillar of the Republic. However, events on Jebble took a dramatic turn when Pulsipher returned from an expedition on Mandalorian-held Taris with the Muur Talisman, an ancient Sith artifact. Pulsipher was unaware of the Talisman's true power: created by Karness Muur, an ancient Sith Lord, to control nearby beings, the Talisman was the source of the rakghoul plague, which transformed those infected into mindless, mutated rakghouls. When the Talisman bonded with Pulsipher upon his return to Jebble, it turned warriors who came into contact with him into Mando-Raks under his command. Influenced by the Talisman, Pulsipher envisioned a future where he used it to unify all living beings under the Mandalorian banner.

The rakghouls, acting on Pulsipher's commands, ravaged the thousands of Mandalorian warriors and recruits gathered on Jebble, quickly killing or infecting nearly everyone near the Ice Citadel with the mutating plague. Two of the few survivors were Celeste Morne and Zayne Carrick, two Jedi who had stowed away on Pulsipher's shuttle from Taris. Fearing the disease could spread galactically, Carrick used the complex's communications dome to warn Cassus Fett, the chief Mandalorian strategist, to keep his forces away. He was then captured and taken back to Pulsipher. When Morne tried to rescue him, the Talisman moved independently, abandoning Pulsipher (who was subsequently torn apart by the beasts he once controlled) and bonding with her instead. Although Morne was almost seduced by the Talisman's power, she recognized its immense destructive potential and willingly entered the stasis casket known as Dreypa's Oubliette, which Pulsipher kept in his laboratory. The oubliette contained the Talisman's power, briefly causing the rakghouls to revert into mindless, rampaging beasts. Carrick and his Snivvian friend Marn Hierogryph narrowly escaped death when friends arrived in time to rescue them aboard the starship Moomo Williwaw.

Almost immediately after Carrick and the Williwaw reached orbit, Cassus Fett arrived with a Mandalorian armada. After assessing the situation, Fett confirmed Carrick's claims about the rakghoul infestation and promptly ordered a massive nuclear bombardment that destroyed all life on the planet and drastically altered its environment. Following the bombardment, Jebble was no longer covered in ice; much of the world was flooded, with only some icy crags remaining above a steaming, radioactive sea. However, Celeste Morne survived, her oubliette remaining intact beneath the waves. Despite the devastation, Jebble continued to receive visitors in the years that followed. Several months after the bombardment, Carrick and Hierogryph tricked Nunk Plaarvin, a Chevin criminal, into visiting Jebble alone, believing he had an important meeting with the Raff Syndicate, a pirate group. Although Jebble's nuclear destruction was widely known, the Chevin was unaware of the planet's fate. By approximately 1419 BBY, Jebble had returned to its former icy state and became a target for ice miners who discovered Dreypa's Oubliette under a kilometer of ice. Unable to open it or determine its contents, the miners assumed it contained something valuable, leading one miner to kill the others and take the casket offworld. The Oubliette, known as the "Jebble Box," changed hands many times over the centuries, and blood was spilled more than once in the pursuit of the mysterious object.

Despite its frozen conditions, Jebble was inhabited by Humans, some of whom fled during the fighting in the early stages of the Mandalorian Wars. After the Mandalorians captured the planet, Jebble became home to hundreds of Mandalorian warriors and scientists who used it as a staging area for recruits from the Outer Rim. Almost all the Mandalorians on the world were transformed into rakghouls after the Muur Talisman was introduced in 3963 BBY, before Cassus Fett's nuclear bombardment killed them and any remaining life. The only survivor of the nuclear attack was Celeste Morne, safely enclosed in Dreypa's Oubliette. She remained in stasis on Jebble for over 2500 years until the planet became habitable again and she was discovered.

The Ice Citadel was a prominent structure on Jebble, a fortress carved into one of its icy peaks that became the center of Mandalorian power after the Neo-Crusaders conquered the world. The Citadel was accessed through igloo-like structures on the icy ground below and overlooked vast ice fields used as training grounds for Mandalorian recruits. Pulsipher's laboratory, where the Neo-Crusader scientist researched Force artifacts and where the rakghoul infestation originated, was located at the top of the Citadel. Following the Mandalorian seizure of the planet, the Citadel also housed a large war forge where armor was made for the various species of the thousands of new recruits joining the Neo-Crusader forces. The Ice Citadel was surrounded by ice mines used by the Mandalorians, which remained intact for centuries after the Mandalorian bombardment and were eventually put back into use around 1419 BBY.

Jebble first appeared in Knights of the Old Republic 26, an issue of the Knights of the Old Republic comic series written by John Jackson Miller and released in 2008. Jebble served as the main setting for the Vector arc and later reappeared in a flashback in Dark Times 11, a continuation of the Vector story that crossed all of Dark Horse Comics' Star Wars comic series at the time. Artists Scott Hepburn and Doug Wheatley provided the illustrations for Jebble in its appearances.
