Yuuzhan'tar

Yuuzhan'tar was the original homeworld of the extragalactic Yuuzhan Vong that was destroyed in a devastating war. It was a living sentient planet with a large asteroid belt around it. In the Yuuzhan Vong language, Yuuzhan'tar meant "Creche of the Gods", and the living planet was a template for the Yuuzhan Vong deities. Yuuzhan'tar was located in the Yuuzhan Vong galaxy. Yuuzhan'tar may have been the basis for Yun-Yuuzhan, the Creator God of the Yuuzhan Vong.

Little is known about the Yuuzhan Vong homeworld. What is known is that the Yuuzhan Vong had once being a peaceful species living as symbionts with the planet. They were also Force-sensitive and their technology was largely organic. This peaceful existance shattered by an invasion of their homeworld by a machine-based civilization that solidified their hatred of mechanical technology.

Eventually, the Yuuzhan Vong managed to drive back the invaders. Their homeworld also helped them by bestowing upon them the knowledge of creating weapons of war. The vengeful Yuuzhan Vong then waged war on their oppresors across the stars and presumably exterminated them. This victory came at the cost of the species becoming warlike.

The Yuuzhan Vong then went on a crusade to cleanse their galaxy of all forms of mechanical technology, thus waging war on other civilizations. 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 Domains disagreed and fought among themselves, 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. In place of their homeworld, the Yuuzhan Vong created several deities which would governed nearly every aspect of their civilization.

Towards the end of the war, Steng served as the first Warmaster. The rival Warmaster, Yo'gand, developed the Yo'gand's Core tactic, which he used to destroy the planet Ygziir and its moon. The destruction of Ygziir resulted in the death of Steng, the end of the war, and unity of the Yuuzhan Vong people. As a result, Yo'gand united the Domains into a single socio-political entity and became the first Supreme Overlord of the Yuuzhan Vong.

However, much of their galaxy was ruined, and the Yuuzhan Vong began the long trek to another galaxy. For millennia, the speces 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. There were no all out wars like the Cremlevian War, but the Domains continued to fight each other for the favor of the Supreme Overlords.
