Yuuzhan'tar

Yuuzhan'tar was an extra-galactic, living, sentient planet in a distant galaxy, far from the main galaxy. It was the homeworld of the Yuuzhan Vong species, and had a large asteroid belt ring around its equator. The Yuuzhan Vong themselves also referred to the planet simply as "the homeworld". It was destroyed in a devastating ancient conflict that forced the Yuuzhan Yong to leave their native galaxy.
In Yuuzhan Vong, Yuuzhan'tar means "Crèche of the Gods"; the living planet was a template for the many Yuuzhan Vong deities. 
==History==
At some point in their history, the extra-galactic Yuuzhan Vong were attacked by a race of droid known as the Abominor, whom were at war with another droid species, at the time, known as the Silentium. The Yuuzhan Vong's living homeworld aided them in their war against these invading droids, bestowing upon them the knowledge of how to create "living", organic weaponry from living (or formerly living) things and materials. However, as the war ensued, 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 leave their galaxy.
Following the war with the droids, the Yuuzhan Vong became embittered and felt immense disdain towards anything they deemed to be inorganic, hence they embarked on a crusade to "cleanse" their galaxy of all forms of mechanical technology. They conquered much of their own local galaxy, and either exterminated or enslaved their conquered species. Among the species they dominated were the reptilian Chazrach, who subsequently became Yuuzhan Vong slave soldiers. However, the Chazrach were, nonetheless, no more fortunate in life than any other race conquered by the Yuuzhan Vong; any and all other races that were not the Yuuzhan Vong themselves were automatically inferior, abominable and/or blasphemous by comparison, and were immediately ranked well below the lowest of the Yuuzhan Vong's strict castes.
With much of the galaxy in their hands, the various Domains 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 now in-ruins, the Yuuzhan Vong began a long trek to another galaxy in search of a new home. For millennia, the Yuuzhan Vong were forced to travel through the Intergalactic Void in their massive, organically-constructed worldships. a period of time they nearly destroyed themselves. Violence and competition had been built-into their society, and, without an external target, they often turned 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.
