Senex - Juvex / Legends The Senex - Juvex was a region on the edge of the Mid Rim of the galaxy that comprised the Senex sector and the Juvex sector . Though the region was nominally split into the two sectors , in practice the Senex - Juvex formed a single cultural region , ruled by wealthy Human noble houses that rejected centralized government and supported themselves through an active slave trade . Formed by a group of Core Worlds nobles led by Thull Vandron around 1000 BBY , the Senex - Juvex fiercely guarded its independence and only joined the Galactic Republic shortly before the Clone Wars . Description . The Senex - Juvex was a dense cluster of star systems distributed around the nebula Thull ' s Shroud . Formed as a rejection of centralized power , there was no government in the region beyond that of the noble houses , which controlled their own planetary fiefdoms . Of the seventeen families that originally set out from the Core , nine settled the systems in the eastern reaches of Thull ' s Shroud , forming the Senex , while eight families settled the western systems , forming the Juvex . The Senex - Juvex became a region of vast agricultural worlds ruled by aristocrats , pleasure planets , and wilderness worlds reserved for nobles ' safaris . The region ' s native species were almost totally enslaved to the Human aristocrats . On the rare occasions when a region - wide policy was required , the noble houses would meet for councils or synods on the pleasure planet Nantama . Neelanon and Juvex were the nominal capitals of the respective sectors , though within the Senex - Juvex this meant little . More important in the Senex were Karfeddion , the homeworld of House Vandron and a major agriworld ; Atron , a major urban , industrial and commercial center controlled by House Garonnin ; Doreen , a waterworld controlled by House Petro and the source of Doreenian ambergris , a traditional perfume ingredient ; and Suliana , a cotton - producing tradeworld controlled by House Hax that served the Tangles . In the Juvex sector , Kassido was an urban world that controlled Coreward trade , making it one of the most - populated and wealthiest planets in the region ; Deminol was a bustling port world known for its universities ; Resti Kel was an industrial world controlled by House Kellermin , known for its athletic competitions ; and Loovria was a world infamous for its gladiatorial fights . Under the Galactic Empire , the Senex - Juvex bordered the Ninth Quadrant , the Agarix sector , the D ' Aelgoth sector , and the Hadar sector . The Senex Trace stretched east to connect Karfeddion with the Rimma Trade Route near Sullust . Other routes in and out of the region were the Veron Route , the Anturi Reach , the Velga Route , the Agarix Trade Route , and the D ' Aelgoth Trade Route . The main route within the Senex - Juvex was the Senex - Juvex Loop . History . Formation . Following the defeat of the Brotherhood of Darkness during the New Sith Wars , the war hero and hyperspace explorer Thull Vandron was elected to the Galactic Senate . A great opponent of centralized government power , Vandron helped craft the Ruusan Reformation s that decentralized the Galactic Republic . Vandron felt that the reforms ultimately did not go far enough , however , and he gathered a group of like - minded , wealthy Core World families and headed into the outer reaches of the galaxy . Following secret hyperspace routes that Vandron had discovered , they settled the systems around a nebula on the edge of the Mid Rim that was later named Thull ' s Shroud in Vandron ' s honor . Vandron and his followers rejected any government beyond that of their own noble houses , which numbered seventeen . Nine houses — Vandron , Garonnin , Elegin , Anturi , Taneel , Petro , Araba , Hax and Viholn — settled the eastern reaches of Thull ' s Shroud , forming the Senex . The western systems became the Juvex , divided among Houses Sreethyn , Carbinol , Halliikeenovich , Sisemon , Kassido , Kellermin Pilor and Mekuun . The settlers ' technology was far ahead of the region ' s native species . Conquering world after world , the seventeen houses took control of all of the habitable planets they could reach and by 900 BBY , had consigned virtually all the region ' s species to slavery and were the unquestioned masters of the region . Early in its history , the Senex and the Juvex were divided into four quadrants each . Conflict with the Republic . For nearly two centuries , the Senex and Juvex Lords were secure on their plantation worlds , doing little more than conducting aristocratic , dynastic plots against each other . Republic scouts soon began penetrating the Mid and Outer Rims , however , and the Senex - Juvex faced a powerful new rival in Eriadu , dominating the crossroads of the Hydian Way and Rimma Trade Route in the southern Outer Rim . In 700 BBY , the Houses annexed a a swath of adjacent systems as a buffer zone against Eriadu , establishing the Ninth Quadrant . The Senex - Juvex and the Galactic Republic coexisted uneasily . The Houses rejected the Republic ' s entreaties , sometimes going as far as to mine the hyperspace routes into the region . The Senex - Juvex ' s isolationism and aristocratic rule made it the subject of many wild spacer tales , many of which were on the whole true . In the Republic ' s last centuries , traders and merchants forged new routes into the Senex - Juvex and the Houses realized that they had fallen behind the wider galaxy technologically . The Crimson Days . The Senex - Juvex ' s backwardness was brought home to the Houses in 553 BBY , when the warlord Osted Picutorion married Farasa Anturi , the mad princess of House Anturi , the weakest of the Senex houses . Picutorion then began a war known as the Crimson Days , defeating the combined forces of Houses Vandron and Petro , freeing the Hutlarian s from slavery , and occupying Karfeddion . The Crimson Days came to an end with the Third Nantama Synod , which accepted the independence of Hutlar and the marriage of Picutorion and Anturi . Within a century , House Anturi had become House Picutorion , and the rebellious Juxex House Mekuun had dissolved its holdings and sought recognition as a Republic sector . Meanwhile , the Republic forcibly annexed the Ninth Quadrant as part of the Bozhnee sector . The Rise of the Empire . At the Fourth Nantama Synod , the Houses of the Senex - Juvex accepted political realities and agreed to seek peace with the Republic . The Republic split the region into the Senex sector and the Juvex sector , though the Houses generally did not recognise the division . They did , however , return two Senators to Coruscant and began negotiations with various megacorporations to open up the Senex - Juvex ' s commerce . The Senex - Juvex ' s active slave trade fell afoul of the Rights of Sentience clause of the Galactic Constitution however , and the Houses ' refusal to abandon something they considered an integral part of their culture meant that the Galactic Senate imposed serious restrictions on trade with the region . The Houses were forced to do business through front companies and criminal groups . Around 33 BBY , the terrorist group known as the Nebula Front operated out of the Asmeru system in the Senex - Juvex . The Houses ' assistance in suppressing the Nebula Front meant that the Republic relaxed trade restrictions somewhat . After the Declaration of a New Order in 19 BBY , the Senex - Juvex Lords benefited from the Galactic Empire ' s abolition of the Rights of Sentience clause and Emperor Palpatine ' s legalisation of slavery as a punishment for " crimes against the civil order " . This allowed the Houses to continue their slave trade on the basis that their rule constituted the civil order in the Senex - Juvex . Later history . The Senex - Juvex Lords were able to continue their activities undisturbed in the chaos that followed the Battle of Endor in 4 ABY . Neither Grand Admiral Thrawn nor the New Republic made significant inroads there during the Galactic Civil War . In 12 ABY the former Emperor ' s Hand Roganda Ismaren approached the Senex - Juvex Houses for financial support for her scheme to proclaim her son Irek a new Emperor . New Republic agents disrupted the meeting of nobles on nearby Belsavis , however , forcing Roganda Ismaren into hiding . The Senex - Juvex accepted refugees during the early Yuuzhan Vong War , though many saw this as a cynical attempt to gain a new influx of slaves . Droma intended to take the Ryn to the region in 26 ABY .
