Gree

The Gree were a species of tentacled gray cephalopods 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
This species were a six-tentacled race of cephalopod creatures that had gray skin with 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 travelling 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
This advanced civilization was noted as being one of the oldest and most ancient in the galaxy. Much of their own history was shrouded to the Gree themselves with them knowing little of their own past with the secrets of their origins being lost. According to most scholars, the Gree were believed to had originated on their own homeworld of Gree hundreds of thousands of years ago. 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. This ancient era when their civilization flourished was known to Gree historians as "the most ancient and forgotten days". By 100,000 BBY, they were known to had shared the galaxy with a number of other races which included the likes of the Celestials, Kwa, Sharu, Columi, Taung and Humans. This period would see them come into conflict with the advanced extragalactic Kwa Holdings which stretched between 27,000 BBY to 25,200 BBY. Eventually, they were pushed back to their borders by the aggressive expansions and military actions of the Rakata's Infinite Empire.

Sometime during their history, the Gree encountered Abeloth, the Bringer of Chaos, when she had 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.

At some point in history, Gree also settled on Coruscant. In 3,643 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.

By the time of the last days of the Galactic Republic and the rise of the Empire, their glory days were long over, and their history and technological secrets mostly lost. They became 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.

Still, the Gree of that era were 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 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.

Society
Gree society at its height had four castes: researchers who produced new devices, crafters who manufactured them, operators who worked those devices, and administrators who ran the government. Each caste was further divided into several guilds, and each world in the Gree Enclave was ruled by a council of guildmasters. 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.

The 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.

The Gree were marked as one among dozens of alien species that were thought to have developed self-aware automata. Despite this being the case, they saw droids as being unworthy technology as they flew in the face of Gree exaltation of personal expertise.

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.
