The Jusadih System is located in the Core, not far from Coruscant, and is the current home of Clan Plagueis. It contains five planets: Kapsina, Sigil 2 (formerly known as Aerun), Nintura, Shintera, and Morroth. It is a volatile system whose star has caused major environmental shifts in its two innermost planets, Kapsina and Aerun. Yet the system serves the Dark Jedi adequately, providing for their immediate needs, and allowing them to remain hidden from outside interference behind a corporate front, Sistros Acquisitions and Holdings.
During the Eighth Great Jedi War, however, the system was discovered by the Yuuzhan Vong and invaded. The small fleet managed to cause severe damage to Aerun, Nintura, and Shintera, but was this pulled off on another mission before it could move on to the remaining two planets. Nonetheless, the economy of the system was destroyed, and is still undergoing repairs today.
Capital of the Jusadih System and headquarters of Clan Plagueis, Kapsina, once a planet of massive oceans, underwent the devastation of Jusadih’s sun, Sigil, turning the once luscious planet into a dry, desolate landscape. Kapsina is composed of five continents: Kurast, Calimcha, Asinai, Schall, Khanduras. Kapsina possesses two Adegan crystal veins, giving the planet great importance to the Dark Jedi. Kapsina was spared by the invasion of the Yuuzhan Vong, but afterwards housed both Clan Plagueis and House Exar Kun due to the devastation of Aerun.
Sigil 2, once known as Aerun, was the former home of House Exar Kun. It was once engulfed in ice, however, much like Kapsina it underwent massive environmental change and was transformed into a moderately temperate climate. The planet is composed of six continents: Tesh-Relin, Decaria, Erineth, Barridon, Kelimar and Nyo. The various terrain types provided by the continents serve as an excellent training ground for Plagueis' ground forces.
During the Eighth Great Jedi War, Sigil 2 was reduced to little more than a barren wasteland. Bombed by the Yuuzhan Vong, all of the major cities and structures on the surface were destroyed and a quarter was terraformed to the invaders’ liking. The once great symbols of Exar Kun, Ash Citadel and Diadem Fortress, were also destroyed in the attack, forcing House Exar Kun to take refuge on Kapsina.
Nintura is a world of lush jungles and abundant life forms, boasting a rich history and the moniker of an ancient culture’s deity of justice. Before Clan Plagueis inhabited the planet, it was controlled by the Ninturan Preservation Coalition, a group of Wookiees who attempted to transform the jungle world into a second Kashyyyk.
The planet is composed of three major continents and numerous islands, the largest of which is Solace. During the Seventh Great Jedi War, all civilization was wiped out from the planet, bombed constantly by the Yuuzhan Vong for hours until every city was gone. Unlike Aerun though, Nintura was not terraformed, but the damage to the planet turned away tourists, so revenue dropped quickly. Repairs are currently being done to bring back the tourists.
Shintera, twin of Nintura and fourth planet in the system, is the primary trading planet for Jusadih. It also possesses the largest population, having many major metropolitan areas in addition to a multitude of smaller settlements scattered across the planet. Shintera is composed of six continents: Sharr, Tethyr, Chult, Theskel, Khurr, Sancrist Isles. It provides the main corporate front shielding the activities of Clan Plagueis from prying eyes, and acts as a gateway between the Outer Rim and the Core Worlds.
Bombed heavily during the Seventh Great Jedi War, many of Shintera's cities were destroyed entirely, but fortunately the Yuuzhan Vong left the system before the whole planet had been run to the ground, leaving some civilizations still standing. All the same, the planet was not fit to house Sistros Acquisitions and Holdings, which was moved to Kapsina. Like Aerun and Nintura, repairs and currently underway.
The outermost planet, home of House Satal Keto, is primarily utilized by the Jusadih military forces for training. The planet is sparsely populated due to its extremely cold temperatures, excluding the major military installations Plagueis built. During the Invasion of Jusadih, Morroth was spared along with Kapsina.
