O ' reenian The O ' reenians were the inhabitants of the planet O ' reen in the Unknown Regions ; although originally Humans , they eventually evolved into a distinct sentient species of near - Human s . The species appeared similar to Humans physically with the exception of orange - hued skin . Their society and culture , on the other hand , were unique in that the O ' reenians were divided into several distinct castes based upon military service . O ' reenians who served in the military for six or more years were granted the rights and privileges of citizenship , while those who did not were relegated to menial occupations of the sort generally carried out by droids on worlds more technologically advanced than O ' reen . Only slaves occupied a social position below non - citizens . A military dictator known as the Magnus ruled the O ' reenian government and commanded its military . The system made O ' reenian society highly regimented and disciplined , with an emphasis on martial prowess . Indeed , even O ' reenian scientists wore sidearms while at work . Although they were descended from colonists sent to O ' reen by the Galactic Republic in the aftermath of the Great Hyperspace War , the location of their homeworld in the Unknown Regions kept the O ' reenians isolated and self - sufficient for millennia . Through several chance encounters with offworlders , the O ' reenians realized that their technology had fallen behind that of the rest of the galaxy , and the government implemented a policy of raiding nearby star systems to take weapons and devices that O ' reenian researchers could then reverse - engineer . These missions , normally carried out by pilots in the O ' reenian Star Corps , afforded the species a sense of protection against what they perceived as outside threats . Government policies of the Galactic Republic and the O ' reenians alike regularly maintained that keeping the species isolated was the most beneficial course of action ; nevertheless , during the Yuuzhan Vong War , the Magnus adopted a policy of potentially taking advantage of the conflict to expand O ' reen ' s sphere of influence . Biology and appearance . Although originally mainline Humans , the O ' reenians evolved into near - Human s , with an anatomy that mimicked that of mainline Humans in most ways . That is , each O ' reenian had a humanoid body , with two arms with five - fingered hands , two legs , and a head ; likewise , their face featured two eyes , two eyebrows , a nose , two ears , and a mouth . The major distinctions between the two species were the O ' reenians ' orange - tinted skin and black eyes . O ' reenians tended to have dark - brown hair . At least some males of the species kept their hair close - cropped , while others sported short goatees . Society and culture . O ' reenian society was highly militarized and stratified . At the top of the social structure was the Magnus , who ruled the species ' s homeworld , O ' reen , as a military dictator and supreme military commander . Below the ruler were the soldiers in the planet ' s militia , a group who were afforded all rights and privileges of citizenship after a period of service of at least six years . Near the bottom of the social ladder were civilians , who had few rights ; such individuals had little choice but to work for the planetary government as indentured laborers . Another non - martial class of O ' reenians were those who were officially enslaved to social superiors . The only group regarded even more dimly than civilians and slaves were soldiers who were dishonorably discharged from the army for shirking duty . The punishment for such dereliction was the loss of all rights and mandatory exile from any settlement on O ' reen . The organization of O ' reenian society into such clearly demarcated castes encouraged disgruntlement among the lower classes , and rebellions were common over the species ' s history — though rarely successful . Although non - O ' reenians were exceedingly rare on O ' reen , the species ' s society allowed offworlders to enjoy the privileges of citizenship through military service or by proving membership in the military of another group . Outsiders who had not done so were regarded as civilians , with rights equivalent to that class of O ' reenians . Non - O ' reenians who did not belong to a military organization suffered severely curtailed mobility on the world . Within the military class , O ' reenians were further stratified according to rank . As supreme commander of the armed forces , the Magnus was elected by a council of his or her peers . The leader received a personal detail of four elite guards for protection and had the ability to rally the O ' reenian military to action when necessary . Another military faction was the O ' reen Star Corps , a unit of pilots who patrolled the O ' reen system and protected it from outside threats . Unless outsiders received proper clearance , the Star Corps refused them access to the planet . A defensive fleet of starships remained in orbit around O ' reen at all times . Life for the O ' reenians was highly regulated and disciplined . O ' reenians learned combat and military skills from an early age so that every O ' reenian could act as a competent soldier when necessary . Even scientists were highly militarized ; laboratory researchers carried small sidearms under their white lab coats . All O ' reenians were more perceptive and fit than a comparable Human , but those O ' reenians who were officially part of the planet ' s military had to show ideological commitment and keep themselves in peak physical condition . The soldier ' s life taught an O ' reenian military protocol ; indeed , lack of such knowledge brought contempt upon many civilian O ' reenians . Criminals were exceedingly rare in O ' reenian society and tended to remain within the fogs that marked the outskirts of civilization . Overall , the O ' reenians had access only to relatively primitive technology ; they lagged behind much of the rest of the galaxy . For instance , most of the tasks performed by droids in the rest of the galaxy fell to O ' reenian civilians instead . Still , the species did have access to items such as datapads and cargo lifter s . The exception was weaponry . By raiding nearby star systems , the military gained access to advanced weapons and armaments , which it then analyzed and adopted . Such bellicose invasions of nearby areas allowed for a robust and advanced array of armaments , which included blaster weapons , sublight drive s , shield generators for starships , turbolasers , and ion drive s . Security satellites filled the planet ' s orbit and provided advanced warning of attack , and orbital defense mines presented invisible , target - seeking obstacles to any outsiders with aggressive intent or who lacked the proper transponder code s . O ' reenian settlements were situated atop towering , flat , natural mesas and plateaux . Their buildings were made of stone and often reached precipitous heights . Such cities tended to be relatively isolated from one another because thick fog that enshrouded O ' reen made travel in the wilds dangerous . The planetary capital was Fort Maximus , the most heavily garrisoned city on the planet . The capital was designed to withstand a siege even for several years , and it housed arms factories protected in underground bunkers . The Magnus lived in an estate at the heart of the city , and most of the populace of Fort Maximus was made up of citizen - soldiers . Epsilon Garrison was similar in that it was more of a military base than a city , although it did support a large farming community that provided food for the nearby garrisons and for the soldiers stationed at Fort Maximus . The large number of civilians at Epsilon Garrison proved one of the more rebellious in O ' reenian society , although the farmers tended to rebel through non - violent protest . Orbital Deployment Center was another city ; its purpose was to operate and monitor the network of satellites that orbited O ' reen to spot threats from afar and to spy on nearby areas of the galaxy to identify possible targets for raiding . Although O ' reen was located just beyond the borders of the Outer Rim Territories within the Unknown Regions , the O ' reenians were a tough and self - sufficient people with little concern for the broader galaxy . Their planet had no exports , although the people did import military weaponry . Indeed , the species was somewhat distrustful and even afraid of aliens . Still , O ' reenian concept of military conduct included the notion that pre - emptive attacks on other groups were sometimes justified , so the species presented a threat to nearby systems ; for instance , the Star Corps raided nearby systems from time to time . The language spoken by the species was derived from an old dialect of Bocce . Even after the two languages had diverged , they remained largely intelligible with one another . Some O ' reenians also learned to speak Galactic Basic Standard and Minnisiat . History . Colonization . After the conclusion of the Great Hyperspace War in 5000 BBY , the Galactic Republic initiated a program of military colonization whereby fortress world s were established in areas of realspace beyond the borders of galactic civilization . The plans for the program called for such colonies to be fully supported with Republic matériel and troops and full two - way communication via the HoloNet . Nevertheless , the Galactic Senate rejected the original proposal as too expensive . The Republic scaled down the project to instead seed self - sufficient colonies that would still offer some degree of protection against future threats . The Republic asked for volunteers to colonize twelve identified worlds , but the number of volunteers was sufficient only for five , O ' reen among them . Shortly after the Great Sith War , which concluded in 3996 BBY , the Human ancestors of the O ' reenians thus traveled to O ' reen under the auspices of the Republic ' s program . With its location in the southwestern quadrant of the galaxy , O ' reen was chosen as a bulwark against an extragalactic force that was feared to threaten the galaxy at the time . A network of satellites was placed in the planet ' s orbit to allow the O ' reenians to monitor nearby systems . However , the threat never materialized . Over time , four of the Republic ' s fortress colonies failed entirely , leaving only O ' reen as a success . However , financial trouble eventually forced the Republic to completely cut ties to O ' reen and its inhabitants . O ' reens vast resources provided the raw materials for the O ' reenians to survive on their own . During the rule of the son of a dandyish Republic functionary , a military officer and starship captain named Magnus took over the government of O ' reen in a bloodless coup d ' état . With widespread public support , Magnus and his advisors introduced a new lifestyle based on military discipline and widespread martial training . " Magnus " became more than a family name ; it became the title of the supreme ruler of O ' reen and its O ' reenian people . With time , the O ' reenians forgot their ties to the Galactic Republic and the circumstances that had led to the settling of their world . Their society stratified into castes , and laws were passed that granted citizenship only to those who served in the military for at least six years . Non - citizens were thus thrust into menial roles . The O ' reenians eventually became a distinct species as well , resembling Humans except for their orange - hued skin and dark eyes . A language derived from an archaic form of Bocce became the species ' s main tongue . Isolationism . Several centuries before the outbreak of the Clone Wars , the O ' reenians made contact with the outside galaxy once again when a corporate exploration vessel found O ' reen . The offworlders tried to claim the planet for their corporation through a display of technological superiority , but the O ' reenians responded with force and took control of the strangers ' starship . The encounter convinced the Magnus that O ' reen was vulnerable to technologically superior and aggressive forces from afar . He ordered the planet ' s scientists to reverse - engineer the ship to improve the capabilities of the O ' reenian military . The O ' reenians then embarked on a program of sending soldiers and scouts on secret raids on nearby planets , during which further technological advances were sought . Over time , the O ' reenians began to reach technological parity with the rest of the galaxy in military hardware . Nevertheless , O ' reenian leaders were cautious to keep the location of O ' reen completely secret from the targets of such raids . During the Clone Wars , a conflict fought between the Republic and the Confederacy of Independent Systems from 22 to 19 BBY , the O ' reenians were faced with another threat when a Republic military exploration ship found the planet during a search for Confederate supply planets . The O ' reenians took the crew captive and enslaved most of them . The Jedi General Morningfire later arrived , supported by the clone troopers of Vornskr Company , to rescue the exploration crew . The Magnus ordered the military to resist the invasion , but the ruler died during the assault . The subsequent Magnus advocated further isolation for the O ' reenians to avoid further contact with the Republic . Meanwhile , the Galactic Senate voted to keep O ' reen isolated from the galaxy to keep the O ' reenians from aiding the Separatists and to curtail any expansionism on the part of the planet ' s people . The O ' reenians remained isolationists until the Yuuzhan Vong War tore through the galaxy beginning in 25 ABY , when the reigning Magnus adopted a policy of watching the conflict between the New Republic and the Yuuzhan Vong from afar , but remaining vigilant against any aggressors , while also keeping an eye out for opportunities to expand O ' reen ' s sphere of influence . After the Battle of Coruscant in 27 ABY , all records of O ' reen were lost to the New Republic . At one point , a group of spacers arrived on O ' reen seeking emergency aid . The offworlders evaded the orbital defenses and landed in the wilderness , but an O ' reenian military patrol found and impounded the visitors ' starship . The spacers infiltrated the city Orbital Deployment Center to recover the ship . When they finally reached the vessel , they made repairs to the ship , entered the vehicle , and lifted off to leave O ' reen . However , some O ' reenians had remained aboard and tried to force the offworlders to land back on the planet . The strangers overcame their stowaways and left the O ' reen system . In another incident , an offworld O ' reenian hired a group of spacers to bring a cargo of high - tech weapons and armor to O ' reen . However , the agent told the group that the cargo consisted of nothing more than miscellaneous goods and luxury items . The patsies traveled to the O ' reen system , evaded O ' reenian system security , and landed . O ' reenian officials boarded the ship , confiscated the cargo , and arrested the couriers for treason against the Magnus and for smuggling . Only after giving up their on - world contact were the offworlders allowed to leave the system — albeit under escort by O ' reenian forces who then set out to arrest the O ' reenian smuggler . On yet another occasion , O ' reenian forces attacked a vessel in the Outer Rim Territories near the O ' reen system . They confiscated a piece of military hardware and carried it back to O ' reen for analysis at a research post near Orbital Deployment Center . There , scientists began efforts to decipher the codes embedded in the foreign devices , and an O ' reenian military supervisor was assigned to protect the hardware until it could be analyzed . Eventually , he received orders to move the cargo to Fort Maximus . Later , a group of offworlders traveled to O ' reen on the orders of a navy lieutenant named Amalia , who wanted the group to investigate the disappearance of the hardware — a prototype tactical computer and tactical data core for a capital ship — and recover it . The O ' reenians attacked the interlopers upon their arrival in the O ' reen system , but the strangers survived the encounter and evaded the rebuilt battle cruiser patrolling the system . The offworlders landed on O ' reen and infiltrated the analysis center where the stolen Republic hardware was kept . The O ' reenian military supervisor detected the intrusion , and in the ensuing skirmish , a dozen O ' reenian researchers were bested by the offworlders , who also recovered the data core . The supervisor ' s datapad revealed the orders to move the items to Fort Maximus , so the offworlders pretended to do just that . However , they instead fled to their ship and escaped the planet and star system . The O ' reenians remained isolated from the galaxy as late as 137 ABY . O ' reenians in the galaxy . With the exception of the Star Corps , which carried out periodic raids on systems near the O ' reen system to steal weapons and technology , the O ' reenians were an isolationist species whose members had little inkling to travel beyond the atmosphere of their homeworld . Nevertheless , a few O ' reenian exiles abandoned their homeworld altogether and made their way into the greater galaxy . The majority of these expatriates found work as soldiers . At least one O ' reenian smuggled weapons and technology to O ' reen by enlisting pilots for hire . In the eyes of the O ' reenian government , however , the agent was an outlaw whose activities constituted treason . Behind the scenes . " The Unknown Regions " , a sourcebook published by Wizards of the Coast in 2010 , describes the O ' reenians and their society as part of its entry on the planet O ' reen . The book , written by Sterling Hershey , Rodney Thompson , and Daniel Wallace , includes three adventure outlines that allow player characters from the rest of the galaxy to visit O ' reen and interact with the O ' reenians . However , the sourcebook offers no timeline information to indicate when these adventures take place . The history above includes the events of these scenarios , but their placement within the broader narrative is completely arbitrary . Also in 2010 , " " , an online supplement to " The Essential Atlas " , placed the O ' reen system and provided further context as to the O ' reenians ' relations with the greater galaxy .
