Ssi - ruuvi invasions The Ssi - ruuvi invasions were a series of incursions into the known galaxy and the Chiss Ascendancy by the Ssi - ruuvi Imperium between 1 BBY to 28 ABY . The Imperium sought to expand its territory beyond the Ssi - ruuk Star Cluster into the surrounding space due to the dwindling resources in their region . The saurian Ssi - ruu k powered and controlled their technology through a process called entechment ; a means of electronically transferring the life - energy of a person into a power source for a mechanical construct . Between 2 BBY to 4 ABY , the Ssi - ruuk launched expeditionary forces against several Rimward worlds including G ' rho , Cattamascar and Bakura . The former two were marginally successfully whereas the latter ended in disaster and exposed the presence of the Ssi - ruuk to the rest of the galaxy . A further campaign into the Chiss Ascendancy brought even more disaster on the Imperium . This was followed by a second punitive raid by a New Republic task force . So great was the devastation of the Chiss attack that it was not until many years later that the Ssi - ruuvi contemplated renewing their expansion . Two major events occurred in that time . One was the birth of the Keeramak — a mutant Ssi - ruu of mixed ancestry with all the colors of the different castes — an event of major significance in the Ssi - ruuvi religion . The Keeramak himself was a master strategist and politician . The Imperium ' s leadership organized a faux P ' w ' eck slave uprising by the P ' w ' eck Emancipation Movement under Lwothin , positing the Keeramak as its leader in 23 ABY . The other event was the secret takeover of the Imperium by the extragalactic Yuuzhan Vong , who secretly placed made one of their own , E ' thinaa , a ranking general . In 28 ABY , the Ssi - ruuvi launched a second invasion of Bakura which failed due to an uprising by the P ' w ' ecks and a counter - attack by the Galactic Alliance . The Imperium itself appeared to have been invaded by the extra - galactic Yuuzhan Vong who had already launched a massive campaign of conquest against the known galaxy . History . Background . The Ssi - ruu k evolved from packs of carnivorous animals on their jungle homeworld Lwhekk . Gradually they formed tribes , each consisted of members with the same skin color . The most dominant were the Blue and Gold scaled tribes . The Blue scaled Ssi - ruuk possessed a great deal of political power , while the Gold - scaled began the Ssi - ruuvi religion . These two would form the Ssi - ruuvi upper class . The Ssi - ruuk eventually encountered the smaller yet more common P ' w ' eck s and conflict arose between the two species . Eventually , the P ' w ' eck s were subjugated and enslaved . The Blue and Gold tribes then made an alliance and selected the first Shreeftut . The Ssi - ruuvi Imperium was born and the Blue and Gold tribes then subjugated the rest of Lwhekk and divided them into castes . The Conclave and the Elders ' Council were formed and eventually the Ssi - ruuk expanded their empire into space . They conquered several worlds and enslaved their inhabitants , most of which were primitives . Eventually the Ssi - ruuk discovered the art of entechment and began enteching subjugated species . The practice of entechment of lower life forms became common ; even the P ' w ' ecks , cousins of the Ssi - ruuk were used . But gradually it was learned that containment of these ' souls ' for long periods would result in madness and it was decided that the Imperium needed to expand its realm once again . Another reason was due the dwindling resources in their isolated region of space . Sometime around 25 , 000 BBY an experimental Ssi - ruuk hyperdrive vessel crashed on the planet Garos IV . For millennia , the reptilian Ssi - ruuk had never dared to expand beyond its cluster , partly because of the large distances involved , partly due to their xenophobic nature , and partly because of their religious fear of traveling to ' unconsecrated ' worlds . Early Incursions . In 2 BBY , the Ssi - ruuvi ' s supreme ruler — the Shreeftut — received visions through the Force of a hooded Human who revealed himself to be Emperor Palpatine , ruler of the galaxy . He offered the Ssi - ruuvi dozens of worlds and millions of Humans to entech , in exchange for the use of Ssi - ruuvi technology . The shreeftut agreed . In response , they decided to venture into Wild Space where they conquered the small Human colony of G ' rho ; capturing numerous members of the populace for entechment . Among their captives was a Human boy named Dev Sibwarra , whom the Elder Bluescale brainwashed through mind manipulation techniques ; what astounded them was the boy possessed strange powers to sense others . It was from this boy that the Admiral Ivpikkis discovered that Humans were the galaxy ' s dominant species . He also discovered that humanoids had longer containment time when enteched and could last longer than most other species . Due to Sibwarra ' s Force abilities and his ability to communicate with his fellow Humans , the Ssi - ruuk used Dev Sibwarra to calm the subjects being enteched . Exploration . In 4 ABY , the Ssi - ruuvi dispatched three separate expeditionary fleets into the galaxy proper and the nearby Chiss Ascendancy as a means of capturing more humanoids for entechment . A sizeable expeditionary fleet led by Admiral Ivpikkis and Elder Bluescale — who had brought along his Human protégé Dev Sibwarra — was deployed against the outlying Imperial planet of Bakura . The second was deployed against the Human world of Cattamascar which the Ssi - ruuvi only narrowly succeeded in conquering . The third fleet attacked and invaded several minor Chiss worlds ; capturing several Chiss as entechment subjects . Ultimately , this expedition incurred the wrath of the Chiss Ascendancy which launched a devastating counter - attack on Ssi - ruuvi space . The expeditionary fleet to Bakura consisted of five large cruisers including the " Shree " - class battle cruiser " Shriwirr " , several dozen smaller support ships and thousands of tiny " Swarm " - class battle droids was . This force quickly destroyed half of the Imperial defense force ; forcing the Imperial Governor Wilek Nereus to attempt communicating with the Imperial commands at Coruscant and Death Star II to seek more reinforcements . When these failed , he sent a message drone to the Forest Moon of Endor ; the nearest world with an Imperial presence and the site of the Second Death Star . However , an Alliance fleet had defeated much of the Imperial presence during an epic space battle which also destroyed the second Death Star along with Emperor Palpatine . Prior to 1 ABY , the remote Outer Rim world of Bakura had been independent of Imperial control but its populace was divided . Seeking to control the planet ' s industrial base and its moon ' s mineral deposits , the Imperials had occupied the planet . Defeat at Bakura . The Rebels intercepted and decoded the message ship . Seeking to entice Bakura into their camp and to secure a truce with Imperial forces , the Alliance leadership dispatched a task force to Bakura led by the Heroes of Yavin including Luke Skywalker , Leia Organa , and Han Solo . Arriving at Bakura , the Rebels were able to secure a temporary albeit shaky truce with Nereus in exchange for support against the Ssi - ruuvi . Meanwhile , the arrival of the Jedi Luke Skywalker — who had just triumphed over the Sith during a heated duel on the second Death Star — created a disturbance in the Force which was sensed by Sibwarra who informed his masters . Believing that they could use the Force - strong Jedi to drain the life energies of millions of sentients from light years away , the Ssi - ruuvi leadership decided to make a covert deal with Nereus by proposing a full withdrawal in exchange for the handover of Skywalker . Nereus accepted the offer ; given his hatred of the Rebels and as part of his secret plan to stab his Rebel colleagues in the back . However , Nereus also double - crossed the saurian aliens by secretly inserting parasitic Olabrian trichoid larvae into Skywalker ' s food during a meal . The larvae would eat into Skywalker ' s body upon hatching before killing the aliens themselves . Nereus would then add the Ssi - ruuk ' s jaw bones to his collection of animal bones . Unfortunately for the Ssi - ruuk , their plans for entechment on a genocidal scale was thwarted by Dev Sibwarra who threw of the shackles of Ssi - ruuvi indoctrination and rebelled against his masters . He freed Skywalker from his bonds and the pair fought their way across the stun trap - littered corridors of the battle cruiser " Shriwirr " . Fearful of dying on an unconsecrated world , Ivpikkis and the surviving crew escaped the vessel in life - pods and were recovered by the other warships . In the space above Bakura , the joint Alliance and Imperial warships launched a devastating counter - offensive against the Ssi - ruuvi fleet . Due to the chaos onboard the flagship " Shriwirr " cause by Skywalker ' s escape and their fear of dying on an unconsecrated world , the Ssi - ruuvi were unable to continue the fight and were forced into a retreat . Every ship in the fleet fled for the safety of Ssi - ruuvi home space except the flagship " Shriwirr " . With the Ssi - ruuk defeated , Nereus put his plans of seizing power and stabbing his Rebel colleagues in the back . He arrested the Bakuran leadership including Prime Minister Yeorg Captison and ordered the Imperial commander Pter Thanas to destroy the Rebel . The former was thwarted by members of the Bakuran resistance movement under the ancient Eppie Belden while only part of the Alliance fleet was destroyed . Ultimately , his efforts were thwarted by a popular rising of the Bakuran people and the last - minute defection of the commander of Imperial forces over Bakura , Pter Thanas . Nereus himself was slain during a failed assassination attempt on the Alliance commander Luke Skywalker . With the defeat of both the Imperials and the Ssi - ruuvi , the Bakurans would join the Alliance and its successor state — the New Republic . Setback . In summary , neither expedition was very successful : the Ssi - ruuvi only narrowly succeeded in conquering the Human world of Cattamascar , and were utterly defeated at Bakura , when it became known that Palpatine , having just been killed , would no longer be able to fulfill his promise . Likewise , although several minor Chiss worlds were taken , the Chiss retaliation was massive and unexpected . In retaliation for attacks on several Chiss worlds which had seen several of their citizens enteched , the Chiss Ascendancy had launched a blistering campaign in Ssi - ruuvi territory ; devastating the Imperium capital of Lwhekk and fragmenting of the Ssi - ruuvi socio - economic caste system . Voren Na ' al of New Republic Intelligence later referred to the battle as the " Bakura Incident " , and believed that it would be best if the New Republic attempted to prevent widespread public knowledge about the Ssi - Ruuk , advice that was taken controversially at best . To prevent a second Ssi - ruuvi attack on the worlds on the edge of Wild Space , the Rebel Alliance ' s successor state — the New Republic — organized an invasion force for an expedition into the Ssi - Ruuvi Imperium ' s territory . This task force consisted of the captured " Shriwirr " which had been renamed " Sibwarra " , 12 Nebulon - B escort frigates and several escort warships . During the expedition , several crew onboard the " Sibwarra " were injured or even killed due to their unfamiliarity with the unfamiliar alien devices onboard the vessel . The New Republic also provided the fragmented Imperial warlords with intelligence on the Ssi - ruuk in the hopes of a securing a second joint attack on the Ssi - ruuk . However when the New Republic fleet emerged in Ssi - ruuvi space , they discovered an already weakened foe . Above the wrecked Ssi - ruuvi capital world , the New Republic fleet clashed with the remnants of the Ssi - ruuvi fleet under Ivpikkis . Having reached a stalemate , the New Republic attempted to negotiate unsuccessfully with the Ssi - ruuk . With the Ssi - ruuk unable to mount another campaign for an unforeseen period and with the growing conflict with the fragmented Imperial warlords looming in the horizon , Chief of State Mon Mothma ordered the withdrawal of the New Republic fleet from Ssi - ruuvi space for an attack on Imperial - held Clak ' dor VII . Resurgence . So great was the devastation of the Chiss attack that it was not until many years later that the Ssi - ruuvi contemplated renewing their expansion . Two major events occurred in that time . One was the birth of the Keeramak , an event of major significance in the Ssi - ruuvi religion . The Keeramak himself , a mutant multi - colored Ssi - ruu , was a master strategist and politician . The other event was the secret takeover of the Imperium by the extragalactic Yuuzhan Vong , who secretly placed made one of their own , E ' thinaa , a ranking general . In the fields of technology , the Ssi - ruuvi made advances in entechment by developing a means of sustaining enteched souls ; allowing them to last longer . They also utilized reverse - engineered captured Imperial starship technology including shield generators and sensor array systems . Meanwhile on Bakura , when her uncle Yeorg retired from public life , Gaeriel won the election to succeed him as Prime Minister , and had the distinction of being Bakura ' s youngest Prime Minister . One of her main accomplishments was the establishment of the Bakuran Defense Fleet ; she placed Pter Thanas , the former commander of the Imperial garrison on Bakura , in command of it . In 18 ABY , Bakura withdrew from the New Republic in protest of the misuse of its Defense Force during the attack on Centerpoint Station during the Corellian Crisis . In Ssi - ruuvi space , E ' thinaa and the Keeramak devised a new strategy for continuing the invasion . they made a secret deal with the Prime Minister of Bakura , Molierre Cundertol . In exchange for gaining “ immortality ” by being enteched into the body of a Human replica droid constructed by the company Onadax Droid Technologies , Cundertol would betray his people to the saurian Ssi - ruuk as entechment stock . In 23 ABY , they engineered a faux P ' w ' eck slave uprising by the P ' w ' eck Emancipation Movement led by the Keeramak and the P ' w ' eck leader Lwothin . As part of their strategy , the faux P ' w ' eck rebels would make overtures of peace to the Bakurans and the New Republic ' s successor government — the Galactic Alliance . Lwothin would also claim that the Keeramak had led a popular uprising of the lower classes which toppled the Imperium and introduced reforms including the abolition of forced entechment and slavery . Consecration . Most Bakurans welcomed these recent developments as a sign of developing relations with their former enemies while others were skeptical . To demonize the opposition and to deflect public attention , Cundertol arranged for himself to be kidnapped by members of the anti - New Republic Freedom resistance movement under Malinza Thanas . Freedom was secretly backed by Cundertol ' s deputy Blaine Harris as a means of reaching his goal of thwarting Cundertol and becoming the new Prime Minister . In order to allow a successful occupation of Bakura , Lwothin and the Keeramak arranged for Bakura to be “ consecrated ” during a public ceremony at a Salis D ' aar podium under the pretext of both species ' religious fear of dying on an " unconsecrated " world . Among those present were delegates from the Galactic Alliance including the former Chief of State Leia Organa Solo , her husband Han Solo , their daughter Jaina and Colonel Jagged Fel — the son of the decorated Imperial ace Soontir Fel . The Alliance flagship " Pride of Selonia " and the Bakuran Defense Fleet were also present in orbit . The Keeramak soon arrived accompanied by two mighty " Sh ' ner " - class planetary assault cruisers plan which remained in orbit . However , the ceremony was interrupted by a bomb attack planted by the Deputy Prime Minister Blaine Harris who had plotted to overthrow Cundertol in order to install himself as prime minister . Luckily , heavy casualties were averted by the efforts of the Jedi Knight Jaina Solo and her mother Leia Organa Solo who managed to apprehend Harris . Despite this , the consecration ceremony concluded and Bakura was christened Xwhee by the Keeramak and his entourage . Taking advantage of the ensuing chaos , the orbiting Ssi - ruuvi ships launched a ground and space offensive ; taking the Bakurans and the Alliance by surprise on land and space . On land , Ssi - ruuvi troops quickly occupied the ruined stadium with little opposition . Meanwhile in space , P ' w ' eck - piloted droid fighters began using their tractor beam projectors to capture and drag the Alliance and Bakuran fighters into the hangar bays of the orbiting Ssi - ruuvi carriers where their pilots would be enteched . Cundertol then reappeared in the presence of the Imperium ' s prisoners and revealed his intentions to betray his people to the enemy . When the Solos rejected their offer of entechment , the Keeramak ordered Lwothin to execute them . However , Lwothin instead assassinated his master the Keeramak with a blast from his paddle beamer . This proved to be the signal for a genuine P ' w ' eck uprising against their Ssi - ruuvi overlords . Taking advantage of the shock , the P ' w ' ecks attacked the remaining Ssi - ruuk which fought back doggedly despite the death of their leader . Realizing that the P ' w ' ecks were their allies after all , the Solos and the Bakurans entered the battle fray . Demoralized and outnumbered , the surviving Ssi - ruuk quickly capitulated while Cundertol was taken prisoner . In space , the captured Alliance and Bakuran fighters were freed by the P ' w ' eck - piloted droid fighters after being led under the deflector shields of the Ssi - ruuvi cruisers . Led by Jagged Fel , the Alliance and Bakuran fighters launched a fierce counter - attack on the Ssi - ruuvi cruisers ; capitalizing on their inability to lower their shields to bring in reinforcements without exposing themselves to enemy fire . Meanwhile on the Ssi - ruuvi cruisers , the P ' w ' eck crew launched a full - scale mutiny in coordination with Lwothin ' s assassination of the Keeramak . Outnumbered and outgunned , the Ssi - ruuk were overwhelmed and defeated . Aftermath . Following the battle , the Bakuran government and the P ' w ' eck Emancipation Movement signed a formal treaty which formed an alliance between the two peoples . Some of the terms of the treaty included holding elections in a month , sharing all captured Ssi - ruuvi assets and supporting a liberation program for the P ' w ' ecks in the Imperium . In exchange for tracing the missing credits and a promise not to engage in anymore illicit activities , Freedom agents Vyram and Malinza were exonerated of their kidnapping charges and their organization was allowed to participate in the elections . Leia predicted that there would be an influx of P ' w ' eck refugees from the Imperium within months and a possible Ssi - ruuvi invasion within a year . Despite this turn of events , Bakura chose not to rejoin the New Republic ' s successor government — Galactic Alliance . However , with the Yuuzhan Vong making new strides with the destruction of the HoloNet , Bakura joined the Galactic Alliance , contributing ships to the defense of Mon Calamari and giving the Galactic Alliance Defense Fleet access to the HIMS technology for use during the retaking of Coruscant . Meanwhile , the deceased Keeramak ' s body was returned on a P ' w ' eck shuttle bound for Lwhekk as a gesture of appeasing the Ssi - ruuvi Conclave while arousing the Elders ' Council . En route , the shuttle was hijacked by Cundertol . Upon arriving at a pre - scheduled asteroid location , Cundertol himself was slain by E ' thinaa — who revealed himself to be a disguised Vong agent . E ' thinaa also claimed that the Yuuzhan Vong had launched an actual invasion of the Imperium ' s territory in 28 ABY in coordination with their attacks on the known galaxy . When the Yuuzhan Vong War ended in 29 ABY , they presumably abandoned all of the Ssi - ruuk Star Cluster .
