Te Hasa Te Hasa was a desert planet with a Type II atmosphere that was located within the Gree Enclave , a part of the Outer Rim Territories region of the galaxy . A hidden planet that had been terraformed by members of the sentient Gree species into a harsh desert world with bioengineered predators , Te Hasa was used for thousands of years to store many pieces of ancient Gree technology that the cephalopoid species had forgotten how to use . The Te Hasan Gree dedicated themselves to rediscovering ways of operating the ancient devices stored in the numerous vaults and warehouses located on the planet , such as the Great Library of Manuals , with many Gree making pilgrimages to Te Hasa in order to study the technological knowledge . Several guilds of masters — members of the Gree operator caste who specialized in the use of various technologies — were present on the desert planet , while a group of Gree from Te Hasa also oversaw the trade of artifacts on the planet Asation . Description . Te Hasa was a terrestrial planet that was located in the Gree Enclave region ' s Te Hasa system , within the Veragi sector of the Outer Rim Territories of the galaxy . The planet was connected to the world of Malanose via a relatively poorly - known hyperlane . The Rokak ' k Baran , a massive transport starship equipped with a Class 3 hyperdrive that was the main method of travel within the Gree Enclave , took two days to travel the route and made regular , two - day - long visits to Te Hasa . The planet was also the destination point of at least one hypergate — a device allowing instantaneous transportation between two points — based on the planet Asation . Although the gate was non - functional by the time of the Galactic Civil War , its use had been common before the civilization of the sentient Gree species declined . Te Hasa was a dry desert world with a temperate climate and standard gravity . The local day lasted twenty - nine standard hours , while a year encompassed 296 days . Te Hasa had a Type II atmosphere , which was comfortable for the Gree who had settled there , although breath masks were suggested for certain other species . Although Te Hasa already had deserts , rocky valleys , and canyons on its surface , the Gree terraformed the planet to be truly formidable to any aliens who might discover the dry world . The deserts were greatly expanded by routing Te Hasa ' s water to underground cisterns that were located under oases in the valleys . Water was also transported to other Gree worlds . As an additional precaution , the Gree bioengineered the native predators to be more aggressive and deadly , while other creatures were engineered to sustain the carnivores . History . Millennia before the Galactic Civil War , members of the Gree species settled Te Hasa . During that conflict , an expedition of Gree from Te Hasa traveled to the planet Asation to find and retrieve the ancient Khoz ' zhak device . The Te Hasans pursued the Human archaeologist Corellia Antilles , who had discovered the artifact in the Asation jungle , and eventually bought the Khoz ' zhak from a group of traders who were working together with Antilles . Inhabitants . Home to 10 , 000 members of the sentient Gree species , Te Hasa was a legendary , secret world that the cephalopoid s used for thousands of years to house ancient technological knowledge and hundreds of unique devices . These artifacts , which the Gree had forgotten how to operate by the time of the Galactic Civil War , were stored and cataloged in warehouses in the hope of eventually rediscovering their use . Dozens of Gree made a pilgrimage to Te Hasa each year in order to study the deposited technology , and occasionally some of them accidentally discovered the correct activation sequences for some of the devices or managed to decrypt the relevant instructions from the Great Library of Manuals , an expansive vault of technical knowledge . Such individuals were then granted the rank of master — a member of the Gree operator caste who was proficient in using a piece of the ancient technology . Those Gree who figured out how to operate some of the stored artifacts could keep those devices themselves , for the Te Hasan vaults contained duplicates , and the local Gree were only interested in the knowledge , not the devices themselves . The Gree from Te Hasa were close in function to priesthood and wore dark - colored robes ornamented with hieroglyphs . Those who made pilgrimages to the desert world wore traditional bright robes and were tattooed to signify that they studied there . The Te Hasans were a closely - knit community who guarded their technology with great care but were ready to accept the help of other Gree in rediscovering its use . A contingent of Te Hasan Gree also oversaw the trade of artifacts on the world of Asation and was allowed to interfere with the trade of advanced technology . Te Hasa was governed by a guild of Gree librarian s , but members of other guilds were also present . The largest number of textmaster s — specialists of information systems and communications devices — in the Gree Enclave worked in the Great Library of Manuals , and master synthesor s , who had the skill of operating matter reconfiguration devices , were also common on Te Hasa . Locations . Te Hasa was the location of the Great Library of Manuals , where only knowledge focusing on technology was accessible to the Gree , as well as storehouses in or near oases in the valleys . The older warehouses were carved into rock , while newer ones , constructed like longhouses , resembled temples rising above the planet ' s surface . Deep in Te Hasa ' s largest desert , " Sik ' ark ' kuck " — which meant " the Swallower " in the Gree language — the Gree stored the most valuable or dangerous artifacts in a restricted and secret warehouse . A landing field was also present on the planet . Behind the scenes . Te Hasa was introduced in " The Gree Enclave " , an article written by Timothy O ' Brien and published in West End Games ' " Star Wars Adventure Journal 8 " in November 1995 . The information was subsequently reprinted in " " , released in 1997 . " The Gree Enclave " includes an adventure seed for use with " " , and this article assumes the scenario plays out as described . The 2009 reference book " The Essential Atlas " placed the Te Hasa system , and therefore the planet , in grid square K - 2 .
