Yuuzhan Vong galaxy The Yuuzhan Vong galaxy was the home galaxy of the Yuuzhan Vong and their original homeworld of Yuuzhan ' tar , the planet Zonama Sekot , the reptoid Chazrach , and possibly the Silentium and the Abominor droid civilizations along with their creators . The galaxy had a vast number of sentient races in it ; however , the Yuuzhan Vong killed off all of them in acts of genocide , save the Chazrach whom they enslaved . The Yuuzhan Vong referred to it as the " ancestral galaxy . " History . Eons ago , a species of star - shaped organics created the Silentium to resemble their form , in much the same way that humanoid sentients created bipedal droids . Though the organics were wiped out by a radiation storm from a nearby supernova , their droid creations lived on . These droids continued to reproduce and improve themselves , and developed a culture based on the prime numbers of five , seven , and eleven . Many of them took on the form of geometric shapes , with the circle being the " holiest " of shapes . Thousands of the wisest members of the droid race created powerful fifty - kilometer spheroid bodies . Two influential members of this giant variety included The One and The Other , and the others were collectively called The Rest . This culture of order and symmetry was soon challenged by the chaotic Abominor , self - constructing droids with a lust for power . The two droid species fought a galactic war , ignoring their galaxy ' s native organic species particularly the Yuuzhan Vong , until the organics fought back and forced both droid powers to flee their galaxy . This war devastated the Yuuzhan Vong home galaxy and triggered the Yuuzhan Vong ' s hatred of machinery and xenophobia toward other sentient lifeforms . Following this war , the Yuuzhan Vong went on a crusade to cleanse their galaxy of all forms of mechanical technology . They conquered much of their galaxy and either exterminated or enslaved conquered species . Among those species they conquered were the reptoid Chazrach , which became slave soldiers for the Yuuzhan Vong . With much of the galaxy in their hands , the various Domain s fractured and turned against each other , resulting in the devastating Cremlevian War . During the conflict , much of their galaxy was destroyed including their homeworld of Yuuzhan ' tar . The exact details of the destruction of their homeworld is lost to the passage of time . However , it is known that the planet produced a seed which eventually became Zonama Sekot . Separated from their original symbiosis with their homeworld , the Yuuzhan Vong were stripped from the Force and experienced great pain . Thus , the species saw pain as the only way to get back to that symbiosis and practiced body modifications on themselves . In place of their homeworld , the Yuuzhan Vong created several deities which would govern nearly every aspect of their civilization . Towards the end of the war , Steng emerged as the first Warmaster . A rival Warmaster , Yo ' gand , invented the Yo ' gand ' s Core tactic , in which he crashed the planet Ygziir s own moon into it , demolishing both . The destruction of Ygziir resulted in the death of Steng and the end of the war . Eventually , Yo ' gand united the Domains into a single socio - political entity and became the first Supreme Overlord of the Yuuzhan Vong . However , with much of their galaxy ruined , the Yuuzhan Vong began a long trek to another galaxy in search of a new home . For millennia , the species was forced to travel through the Intergalactic Void in massive worldships . During this period , the Yuuzhan Vong nearly destroyed themselves . Violence and competition had been built into their society , and without an external target , they focused their aggression against each other . Though there were no all - out wars in the magnitude of the Cremlevian War , the Domains continued to fight each other for the favor of the Supreme Overlords . Upon the discovery of the Galaxy and the living planet Zonama Sekot , the early scouts reported back on the worlds they ' d discovered , ripe for colonization and conquest . Supreme Overlord Quoreal , however , was reluctant to invade , on account of the threat that Zonama Sekot posed . But a member of the Intendant caste , Shimrra Jamaane , realized that the very society of the Yuuzhan Vong was falling apart and that they needed a common cause to rally behind and unite them . Not long after Quoreal ' s decision not to attack was voiced , he was deposed and assassinated in a coup orchestrated by Jamaane , who promptly reversed his predecessor ' s decision and ordered the invasion , thus beginning preparations for the Yuuzhan Vong War . Yuuzhan Vong spies and infiltrators were dispatched into the Galaxy in the decades leading up to 25 ABY . The conflict would become the most devastating in galactic history , with aftereffects that would continue to be felt throughout the galaxy for over a century to come . Shimrra eventually ended up falling under the influence of the disgraced shaper Onimi , who eventually became the secret Supreme Overlord .
