Yuuzhan ' tar Yuuzhan ' tar was the original homeworld of the extragalactic Yuuzhan Vong that was destroyed in a devastating conflict known as the Cremlevian War . It was a living sentient planet with a large asteroid belt around it . The Yuuzhan Vong also referred to it simply as " the homeworld . " In the Yuuzhan Vong , Yuuzhan ' tar meant " Crèche of the Gods " , and the living planet was a template for the Yuuzhan Vong deities . Yuuzhan ' tar was located in the Yuuzhan Vong galaxy . History . At some point in their history , the extragalactic Yuuzhan Vong were attacked by a species of droid . The Yuuzhan Vong ' s living homeworld of Yuuzhan ' tar aided them in the war by bestowing upon them the knowledge of creating living weapons . However , as the war dragged on , the Yuuzhan Vong as a species became increasingly violent and warlike . Eventually , they were able to defeat their enemies , and forced both droid powers to flee their galaxy . Following the 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 . However , 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 as a result 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 used to destroy the planet Ygziir and its moon . 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 . Behind the scenes . In Daniel Wallace ' s endnotes for " The New Essential Guide to Droids " , the war between the Silentium and the Abominor is strongly implied to be the root cause of the technophobia of the Yuuzhan Vong .
