Gree ( species ) / Legends The Gree were a species of tentacled gray from the planet Gree . Each Gree had six tentacles and an over - sized head , in comparison to baseline and near - Human body proportions , and stood between 0 . 8 and 1 . 2 meters tall . Gree evolved in a Type II atmosphere , and generally covered their lower faces with odd spongy devices ( presumably breath masks ) in Type I atmospheres . Biology and appearance . The Gree were a six - tentacled race of cephalopod creatures that had an unusual anatomy with gray skin , large sad - looking eyes along with tall foreheads . These features supported an immense brain sac which flopped oddly behind their heads . There was no visible mouth present on their faces though it was thought that multiple fleshy folds beneath the eyes served vocal oral communication needs . Their evolution on their homeworld meant that they were comfortable in Type II atmospheres with Type I being unpleasant to them . As such , when traveling through such an environment , they wore odd spongy communication devices to cover their communication folds . Gree possessed multiple tentacles with each holding a particular function . The first pair served as fine manipulators , another as heavy grippers , and the third as ambulators . This last pair was used to help a Gree move about its environment where its appearance was that of a shambling mound of gray flesh . Typically , Gree rarely ever grew more than a meter and a half in terms of height . History . Ancient Days . This advanced species was noted as being one of the oldest civilizations and most ancient in the galaxy . Much of their own history was shrouded to the Gree themselves , with the secrets of their origins being lost . Most scholars believed that the Gree developed on their own homeworld of Gree hundreds of thousands of years before the Galactic Republic . Following a long period of evolution , it was thought that they had developed some form of hyperspace technology whereupon they moved to explore the stars . Their initial expansion in ancient times was achieved through their remarkable technology that included sophisticated navigational computers . This ancient era when their civilization flourished was known to Gree historians as " " the most ancient and forgotten days " " . The Gree found themselves to be much more advanced than most other races in that era . Few of these species encountered had even entered into the industrial age . In this time , the Gree traded with these worlds and even ruled some of them . However , they formed a policy of never giving technology to a developing civilization unless they were theoretically capable of developing it themselves . At some unknown point in the distant past , the ancestors of the Gree launched an automated exploration vessel known as the Gray Secant that left the boundaries of the Enclave for its mission to study the entire galaxy . In the Outer Rim , the Gree civilization flourished from 100 , 000 BBY where they reached their apex during the same era as that of the Columi . They were noted to have constructed strange alien marvels that were never duplicated in later years . Whilst a powerful race , the Gree empire faced opposition to their reign in the form of the reptilian Kwa . By 100 , 000 BBY , they shared the galaxy with a number of other races , including the Celestial s , Kwa , Sharu , Columi , Taung , and Humans . During these times the Gree , along with both the Kwa and Killik s , became servants of the Celestials . This era saw them aid in building astonishing technological projects . Around 35 , 000 BBY one of the Celestials ' servant races , the Rakata , revolted against their rule and usurped their domain . Afterwards , the Rakata were known to have waged a war against the other Celestial servant races , including the Gree . This saw the Gree encounter the aggressive and militarily superior might of the Infinite Empire . This period also saw the Gree come into conflict with the advanced Kwa holdings , a conflict which stretched for millennia to 27 , 000 BBY . Eventually , both sides were pushed back to their borders by the aggressive expansions and military actions of the Infinite Empire . Sometime during their history , the Gree engaged in a war with a large saurian species . The war lasted for several centuries , causing such strife and chaos that Abeloth , the Bringer of Chaos , escaped from her prison . In the Histories of the Killik Thuruht hive , a panel depicted a group of Gree sacrificing several members of a large , saurian species to Abeloth on her planet . The Old Republic . Before the rise of the Old Republic , the Enclave closed the borders of Asation from the rest of the galaxy when the Gree entered into a cultural retreat that they called the Orange Conic Era . By the time the Je ' daii Order formed on Tython , the species had long departed the known galaxy . All knowledge of their existence was so far back in history that it had became near legend or myths . During this era , there was much interest among the Tythan s in this ancient race who researched them and their legacy . A number of theories held that the Old City was a settlement inhabited or created by the Gree . By the age of the Old Republic , the Gree were noted for being one of the oldest species in the galaxy and known for both their bizarre as well as wonderful technology . Their glory days of their civilization having ended thousands of years before the rise of the Republic , much of their history was forgotten and their greatest achievements were lost to their people . The majority of Gree lived in seclusion within their territory in the Gree Enclave , a mid - sized region of space that was carefully isolated from outside contact . While isolationist , the Gree were still well known for their reputation as engineers and artisans of unmatched skill . One instance of limited contact between the Gree and the galaxy outside occurred shortly after the end of the Great Sith War , when several hundred A - series assassin droid s designed by Anx scientist Pollux Poi and upgraded by Rakata n technology left Kashyyyk for Gree space . There , a Gree clan employed them as assassins . These droids remained in Gree space for thousands of years . At some point in history , Gree also settled on Coruscant . In 3643 BBY , during the Old Republic era much of Coruscant ' s lower level constructions , such as power production and waste processing was still of Gree technology . At the time , there was a delegation of Gree droids present on Coruscant to oversee the maintenance of these machines . The Sith Emperor was noted to have used Gree technology to create a cloaking device for his personal space station . At some point , the Sith Empire managed to recover a Gree computer . It was believed by the Republic Strategic Information Service that the device was recovered from an ancient derelict vessel whereupon it was studied on Dromund Kaas . After recognizing its potential , the Sith were believed to had used it to safely navigate to the Maelstrom Prison following an adaptation of the computer interface for use by humanoid species . During the time of the Grand Acquisitions Race , it was noted by the Chevin Conglomerate that a Gree fleet was returning to known space for some mysterious purpose . In fact , the legendary vessel known as the Gray Secant began its journey to the planet Ilum as the conflict between the Republic and Sith became subject to its study . Afterwards , agents of the Dread Masters continued their plans by taking control of a Gree Hypergate on Asation where they began transporting hordes of creatures to the planet . As a result , the Gree dispatched their ambassadors to gather help from the galactic powers . Administrator General Lalat ' k was sent to the Sith Empire to gather their aid whilst Gatemaster Beltek ' k was dispatched to the Galactic Republic . Imperial Era . In the final years of the Galactic Republic , the Gree were still best known as a species that had built a civilization that predated the Republic . As a result , the worlds of the Gree were noted for being a xenoarcheaologist ' s treasure trove that contained artifacts of exotic and advanced technology . These relics were guarded by a Gree culture which had degenerated to a point where they were no longer able to use much of their own technology . During the Rise of the Empire era , the glory days of the Gree were long over and their history and technological secrets mostly lost . During the Separatist Crisis , Count Dooku formerly of the Jedi Order was sighted within the Gree Enclave where the Senate Bureau of Intelligence had reports of a man matching his description being onboard the mobile Rokak ' k Baran station . There were also claims of him utilizing a vessel with a particle - wake unlike any encountered before that led to Director Armand Isard commenting that contact was being made with Gree crafters to inquire if they knew anything about the technology employed . At this point in their history , the Gree were still able to operate and build some unique items . Count Dooku ' s personal Geonosian solar sailer was fitted with an ancient , mysterious sail of Gree manufacture . The Trident - class assault ships created by the Colicoid Creation Nest were craft that drew upon the ancient designs of the Gree Enclave . Midway through the Clone Wars , the Pollux Poi assassin droids were purchased by Count Dooku from the Gree where they were utilized on Jabiim . The Gree remained an obscure species , known only to specialists in alien cultures such as clone trooper commander CC - 1004 . CC - 1004 adopted the name " Gree " to demonstrate his knowledge of galactic species , knowing that anyone who commented on his chosen name would share his interest in sentientology . On the other hand , Gree were almost entirely unfamiliar with standard galactic technology . They were particularly contemptuous of droids , which were not a part of Gree technology . Modern Gree became reduced to being mere caretakers of decaying wonders . First contact with the Gree by the Empire was made by Captain Marrix during a scouting expedition through their sector of space . He was apparently highly respected by the Gree to the point that he was allowed to visit their homeworld once . The Galactic Empire maintained a small consulate on Gree though there was no governor or garrison . The Imperial Consul - General maintained a small force under his command that included a " Carrack " - class light cruiser . Skalus served as the Imperial Consul - General on the Gree world of Asation . Society . Gree marked their foreheads with hieroglyphic tattoos to denote caste and rank . As Gree engineering reached its zenith , the operators came to dominate the other castes . Eventually , the researchers and crafters disappeared entirely . Their society became apathetic , with the operators and administrators concerned only with maintaining their cultural purity and keeping what devices they could still understand in operation . In the past , their society was divided into four castes that were roughly equal to one another : These were the primary castes within the Enclave . The Gree lacked any form of a warrior caste and instead had used droids in the past for such a role . Within each caste were a number of subgroups or guilds that were responsible for their operations in the caste . Whilst initially the four castes were equal to one another , the rise in Gree technology to its zenith meant that the Operator caste eventually began to dominate its counterparts . As a result , the Crafter and Researcher castes eventually disappeared entirely by the time of the Imperial era . The reasons for this were twofold ; the first being because there was no need of them within the slowly dying Gree civilization , and secondly because the Gree had forgotten the bio - engineering processes needed to produce members of those castes . The general Gree masses of latter era tended to be near mindless in their actions with few entering the role as operators . Instead , they were willing to aid the master by performing the few services that justified them being clothed and fed . Such individuals were capable of being Gree that were attached to a master due to their caste and guild . However , they tended to had minimal skills , holding short attention spans and only performed brief actions in order to either acquire sustenance or wealth . These members of the race also were able to find employment under Gree traders where they used their small array of talents for some use . The traders , whilst considered a part of these masses , but were actually above the common rabble due to their ability to trade for goods and services . These Gree were looked down upon by the masters , but were accepted as part of their society due to their ability to bring in new clients or goods from the space outside the Enclave . By modern era , a somewhat new group of traders emerged among the Gree known as the Sevark s who acted as translators and intermediaries between a master to alien client . Amongst the highest ranking position for the Gree were those that held the title of grandmaster who were recognized as the prominent master of their field on a world . Beneath them were the guildmasters that headed the local guilds . Beneath them were the masters who dominated their society and were respected by their fellow Gree . As such , they gained a preference over any other being that were seen as a " " lesser " " creature and also held a seat on the local guild of their profession . It was the masters that operated their races technology that maintained the Enclave and thus expected some form of tribute for their knowledge as well as services . It was for this reason that they tended to jealously guard their knowledge , and many secrets became lost as a result of such Gree hoarding their skills instead of passing them on to successors . Beneath them were the potential masters in waiting in the form of senior assistants who had not reached a mastery of their particular field of study . The majority of these individuals tended to be simply waiting for an empty suit on their guild . Senior assistants were responsible for assisting a master in the performance of their work . Students were apprentices junior to them who served and learnt from their experiences that were numerous , but rarely ascended to the rank of senior assistant . Instead , they simply aided the senior assistants and performed the menial tasks of the masters in the operation of a device . The worlds of the Enclave were governed by a grand council that consisted of members of the local guilds that met when needed . These in turn answered to the grandmaster council located on the Gree homeworld . The guilds themselves served as a regulating group for the local caste subgroups such as constructors , synthesors and textmasters . It was the master on a Gree world that held a council seat of their respective guild . Each guild council only had a limited number of seats that restricted the rise of new masters . Gree language made use of metaphors based on geometry and colors which other species had difficulty understanding . Technology . Much of the Gree ' s technology was developed thousands of years ago and was extremely alien to anything known by modern eras . Their ancient technology had millennia ago surpassed that of modern Imperial technology . At their peak , they had mastered stellar engineering , quanta - technology , and dimensional engineering . As such , the oldest Gree technology in existence was remarkably advanced with their high technology on a level far beyond the Imperial equivalent . Much of this consisted of devices that emitted music when operated as they functioned as instruments that needed to be " " played " " in order to function properly . They also created artificial intelligences that could be contained within artifacts and were strong enough to seize control of a starship . The race possessed sophisticated navigational computers that operated on principles that were a mystery to other technologists . These capabilities allowed their vessels to safely traverse turbulent regions of space that included vast asteroid fields and dangerous nebulae . The interface of these Gree computer s was designed for the six - limbed cephalopodans . The Gree were marked as one among dozens of alien species that were thought to have developed self - aware automata . In fact , their entire military force consisted of droids that were used by the Gree to combat their foes . However , by the time of the Galactic Civil War , they saw droids as being unworthy technology as they flew in the face of Gree exaltation of personal expertise . Other capabilities achieved through their technology included the capacity to xenoform entire worlds to their standard . Furthermore , they were able to introduce genetically engineered primitive organisms designed to maintain artificial ecosystems . It was the progenitors of the Gree that also developed their Hypergate technology that allowed immediate travel from one point to another . Among their starships included the rare Gree sailships . They were also able to produce ancient , mysterious sails of their own manufacture as seen on Geonosian solar sailers . They had also produced much larger starships that were more akin to moving cities than vessels such as the Rokak ' k Baran .
