Galidyn The Galidyn were sentient reptilian predators indigenous to Fyodos . Biology and appearance . The Galidyn were large , airborne lizards , ranging from two meters in length with a four meter wingspan , to five meters in length with a ten meter wingspan . They possessed a long tail , and had small prehensile arms with two digits . Though they had a great love for knowledge and a expansive vocabulary , a Galidyn was a deadly foe when angered . Their proboscis hid sharp teeth within , and their scaly skin was exceedingly tough . They had extremely long lifespans , upwards of four thousand years . As they aged , they became stronger , rather than weaker . They produced a single egg every century . Society and culture . The Galidyn were a keenly intellectual and curious species , prizing the creation of ideas and discussion above all else . Rarely , some Galidyn would " go native " and prey on the wandering herd animals of their planet . Their government was a participatory democracy . Their planet had eight cities , each made up of smaller communities . Each community had a few hundred beings , and cities had upwards of five thousand citizens . These cities were at least one kilometer beneath the surface of the planet , and are made up of technology - laden caverns . They installed lights , security systems , and environmental controls to the caverns , and the cities also possessed geothermal power plants , fungus parks , and extensive living quarters . Their structures were made from refined metals and plastics . Each city was governed by a single Galidyn , whose tile was " Steward " . One city was ruled by Ssseeeeseetek , who , at four thousand years old , was the oldest and strongest being on the planet , as well as the most respected . Reproducing only once per century , these singular children were initially cared for by their immediate family . After some time , the youth were then sent to an elder mentor , who would school the child on a range of subjects covering history , computers , medicine , hunting , mathematics , language , and aerodynamics . Any Galidyn who completed their studies could participate in the government . The Galidyn spoke the same language as the Fyodoi , the Human colonists of their planet . The Galidyn speak the language in its purest form , while the Fyodoi speak an altered , lower form . While the Galidyn can understand the Fyodoi , the Humans can only understand a few words , and often led to unforeseen complications . If an offworlder was spotted on the planet , they would be escorted to the " Crater of Debate " , an open meeting place . They would then be asked to explain their presence on the planet and where they came from . The Galidyn themselves had little desire to leave their planet , though some would . History . Long ago , the Galidyn coexisted with the Fyodoi . However , in 350 BBY , the Fyodoi waged a terrible war amongst themselves , called the Great Cleansing . Their advanced technology ravaged the planet , and destroyed the Human societies . The majority of the Galidyn escaped the slaughter by retreating into underground caves and hibernating for almost two centuries . After the conflict ended , the Humans fled from their ruined cities , deciding to shun their destructive technology , and eventually regressed to a primitive level . The Galidyn initially attempted to reconcile with the Humans , and bring them back into society , but the Fyodoi had begun to regard them as technology - worshipers . Though they felt pity for the Fyodoi , they decided to leave them alone . When the Empire took power , they sent probe droids and scouting parties to the planet . The Galidyn hid within their underground cities , and used sensor jammers to mask their presence . The Empire remained unaware of the Galidyn ' s existence , and never established a base there .
