B ' rknaa The B ' rknaa were a mineral - based sentient species native to Indobok , a moon orbiting the planet Kalarba in the Mid Rim region of the galaxy . In actuality , the moon was itself an enormous member of the species . The B ' rknaa ' s true appearance was that of crystalline clusters , but their inner energy could induce life into inanimate matter . When they were deemed old enough to take up a host body , the B ' rknaa crystals animated giant stone husks in which they could move about . These sentients were considered unusual by Humans , and they were known to Jedi biologists for their resistance to Force abilities . The B ' rknaa were also capable of merging together several stone bodies to form a much larger unit . The B ' rknaa of Indobok were known to the wider galactic community since at least the first millennium before the Battle of Yavin . Compared to the civilized worlds of the galaxy , their technology level was very low : they did not build cities and wore no clothing , but they did develop a language of their own . Despite their bulky appearance , they were usually friendly to strangers , with the notable exception of those who tried to steal B ' rknaa crystals . Around 6 BBY , the pirate Jace Forno planned on stealing some of them so she could supply the black market . Thanks to the intervention of the Pitareeze family from Kalarba , Forno ' s henchmen were driven off , and her plan was thwarted . Twenty years later , during the Great War , the B ' rknaa were put in jeopardy when the Yuuzhan Vong , a species of extra - galactic invaders , destroyed Kalarba , dispersing radioactive material across the system in the process . Biology and appearance . The B ' rknaa hailed from Indobok , a heavily cratered moon orbiting the planet Kalarba , near Hosk Station in the Mid Rim region of the galaxy . In their purest form , the B ' rknaa appeared as blueish , irregularly faceted and roughly cylindrical crystals , which gathered in clusters on the surface of Indobok . Their crystalline nature made their biology similar to that of the Shard s from the planet Orax and the Tsil of the planet Nam Chorios . The B ' rknaa prisms were able to channel vast amounts of complex energy ; in fact , one large B ' rknaa specimen was enough to handle all the systems power of a planetoid . B ' rknaa had the power to animate inert materials , which they then used as host bodies . When they were considered old enough , a B ' rknaa took control of an enormous , bulky form made of rock — the only substance available in sufficient quantities on the moon . In fact , the moon of Indobok itself was a single , massive , adult B ' rknaa . All other B ' rknaa on its surface were its " offspring , " in that all B ' rknaa were controlled by one shared mind . Brown or gray , their giant , bulky host shells appeared humanoid in shape , with two legs and two arms ending with four - fingered hands . Their legs were roughly shaped like pillars , and their feet were almost round . A typical B ' rknaa body featured an ashen , expressionless face with a gaping mouth and two forward - facing , white eyes . Several units were able to join their bodies to form larger and more threatening beings . The stone beings from Indobok were also immune to every direct application of the Force thanks to their mineral - based structure and their hive mind . Scientists of the Jedi Order theorized that the Force itself allowed certain species to develop barriers that could redirect its flow . Society and culture . On Indobok , the B ' rknaa who took stone bodies led a simple lifestyle , considered archaic by galactic standards . They did not build cities or communal habitats , living in the open air , and they wore no clothing . Despite their brutish and frightening appearance , the B ' rknaa were indeed sentient . They usually were peaceful and welcoming , only showing signs of aggression toward those who wanted to steal their precious crystals — which were not mere commodities , but were in fact younger , unshelled B ' rknaa . When they were considered old enough , the B ' rknaa prisms were given a humanoid stone husk that was animated simply by putting the crystal cluster inside it . While moving around in their stone shells , B ' rknaa were capable of speech . Their language consisted of creaking and cracking sounds . Although it was possible , at least for a protocol droid , to learn the basics of the B ' rknaa language in a few days , some of its concepts were difficult to translate to Galactic Basic Standard . Like the Killik s , the Taurill , and many other species , the B ' rknaa didn ' t recognize individuality , due to their shared mind . Indeed , there was no first person personal pronoun in their language . When a single stone giant spoke , it voiced the opinion of the whole species . History . The crystalline B ' rknaa and their rock bodies were known to the Jedi Order by at least 1000 BBY . The Jedi noted that the B ' rknaa were difficult to affect with mind - based Force powers , and the rock beings were resistant to all direct applications of the Force . Following the Ruusan Reformation , the Jenet Grand Master of the Order , Fae Coven , created " " . In this guidebook , the Tynnan biologist Bowspritz mentioned the B ' rknaa in a chapter entitled " Advanced Cultures and Politics in the Republic , " listing them among those species resistant to the Force . Outside scientific circles , the stone giants of Indobok remained largely unknown , unlike other mineral sentients such as the stone eel s of Storthus . Even the Pitareezes , a Human family from Kalarba , did not know of the species before they encountered mobile B ' rknaa in 6 BBY . That year , the Corellian thief Jace Forno intended to visit Indobok and steal a bag of crystals , hoping she could sell them on the black market . Forno rented two droids from the Pitareezes — the protocol droid C - 3PO and the astromech droid R2 - D2 — so they could accompany her to the cratered moon . The Corellian pirate ordered the droids to find crystal clusters and take as many as they could while she took care of the stone giants . C - 3PO successfully stole a single large crystal , but several B ' rknaa in stone form thereafter attacked Forno and the droids . The party then ran to their starship for safety , but C - 3PO could not make it in time because his joints froze . Forno abandoned the gold - colored protocol droid on Indobok , intending to come back later with more men and weapons . While abandoned on the moon , C - 3PO discovered the truth about the B ' rknaa ' s gentle nature and their sentient crystals . Eventually , the Baron Pitareeze , headed for Indobok — along with his son Jarth , her daughter - in - law Meg , and his grandson Nak — to rescue C - 3PO . Much to their amazement , the Kalarbans made their first contact with the B ' rknaa . Through C - 3PO , the Humans befriended the B ' rknaa and spent the night on the moon . Suddenly , Forno and her minions landed on Indobok , ready to do battle against the stone giants . The B ' rknaa put up a valiant defense with the help of their new Pitareeze allies . The stone giants fought their enemies with their fists , eventually merging together into a single , colossal entity . The united B ' rknaa shattered one of Forno ' s armed vehicle on the ground . The Corellian thief ' s henchmen were no match for the mineral titan , and they beat a hasty retreat . The precious B ' rknaa crystals were thus restored to safety . Nearly twenty years later , in 26 ABY , the Yuuzhan Vong , a species of technophobic invaders from another galaxy , endangered the B ' rknaa . In an assault against Kalarba and its moon , the Vong used Yo ' gand ' s Core , a battle tactic that they had employed earlier on the moon of Sernpidal . Hosk Station , Kalarba ' s other moon , was drawn in , and both the planet and its station were destroyed in the process . As a consequence of the impact , radioactive material was spread across the whole Kalarba system , rendering it uninhabitable for centuries . B ' rknaa in the galaxy . Because of their ability to channel energy , B ' rknaa crystals were considered precious commodities by the few off - worlders who knew of their existence . The thief Jace Forno once sold a single crystal for fifty thousand credits . She intended to steal as many clusters as she could and sell them on the open market in order to gain substantial income . Behind the scenes . The B ' rknaa first appeared in July 1994 , in the of the " " comic book series . The story was written by Dan Thorsland and pencilled by Bill Hughes . As Indobok itself is a member of the species , the list of appearances below includes the works in which the moon was featured . After a sixteen - year hiatus , the B ' rknaa were mentioned in " " , a reference book written by Daniel Wallace and published on September 28 , 2010 . The species had its own entry in a guide to important or unusual alien races , complete with a stylized illustration by Derek Thompson . In the book , B ' rknaa were described as " rock - based creatures . " This description apparently refers to their mobile bodies , since the beings themselves are crystalline in nature . The words " rock " and " crystal " cannot be used interchangeably . A is a pure , meaning it has an exact chemical composition , while a is an aggregate of two or more minerals .
