Yvarema The Yvarema were bipedal sapients indigenous to Yvara . The Yvarema were an example of a non - insectoid hive - mind species . Consisted of several different classes , they were ruled by the Majjvara , and each was totally dependent on the other . Biology . Before the Yvarema developed sufficient technology , the Majjvara would lay eggs in a protected chamber and create the various classes needed for Yvarema society . By 8 ABY , the egg laying had been eliminated , and the Majjvara produced embryonic cells that were developed in incubators . The Yvarema employed a hive - mind based on pheromonal and empathic links . Unlike other hive - mind species , each Yvarema had a unique and distinct personality , and there were no mindless drones . However , the intelligence of a Yvarema was based on the number of other Yvarema present within a given area . The more Yvarema around , the smarter an individual Yvarema became . When cut off from the hive - mind , they lost their intelligence . Because of their hive - mind , Yvarema were susceptible to feelings transmitted through the hive by the empathic link . Because of this , Yvarema felt great joy and happiness , but also experienced fear and danger . As a result , several of the Yvarema classes were bred with limited sensitivity to reduce any negative experiences being transmitted through the hive . The Yvarema hive - mind made them capable of empathic perception with other species , but on a limited level . Yvarema could sense the emotions of others around them in general terms , and determine if an individual was friendly or not . Yvarema classes . The Yvarema consisted of several classes , each bred for a specific role and function within Yvarema society . Worker . The worker was the most common Yvarema . A neuter sex of strong bipeds , they were trained for a variety of roles , including construction , sanitation and maintenance . By 8 ABY , Yvarema droids were being produced in greater numbers , meaning that the Majjvara ceased producing workers in large numbers . Explorer - scout . Slender and quicker than the workers , the explorer - scout Yvarema was identifiable by a large water and fat - retaining hump on its back . Intended for long journeys beyond the hive , the explorer - scout ' s empathic link has a greater range . Explorer - scouts patrolled beyond the hive , searching for food and resources for the workers to exploit . They were also used to guard the outskirts of the hive from predators . They also had better vision in low - light situations , and a less perceptive tactile sense so any dangers they encountered could not endanger the hive . Lore gatherer . Serving as librarians and scholars , the lore gatherers are the longest lived Yvarema next to the Majjvara . They have enlarged craniums that hold large minds , meaning they had an enhanced empathic sense . To avoid the pain that workers and explorer - scouts felt on a day - to - day basis , lore gatherers generally sealed themselves away from the hive until their area of study was needed . Royal explorer . The royal explorer were a class of Yvarema that were bred by the Majjvara for the purpose of deep space exploration . Imbued with a stronger personality and a limited intelligence buffer , the royal explorers were only twelve in number . Due to the Yvarema hive - mind , space - exploration was problematic because the further a Yvarema traveled from the hive , the more of his intelligence and faculties were lost . To combat this , each royal explorer was accompanied by a lore gatherer , three workers , and two explorer - scouts . The group would never separate by more than one hundred kilometers . Royal explorers that were separated could survive away from the hive - mind . Due to the limited intelligence buffer built into their brains , they retained some semblance of their past self , but their intelligence was vastly reduced . The most famous royal explorer was Gunthar , who traveled beyond the Kathol Rift , and returned on the New Republic ship " FarStar " . FarStar warriors . Created in 8 ABY , the FarStar warriors were a warrior class bred to defend the hive following the unwanted attentions of the Qektoth Confederation . They resembled a cross between Gunthar and the Sludir Qesya Vth ' naar . Their creation caused the Majjvara ' s life to shorten .
