Xynos developed a rare fascination with magic, perhaps because of his time spent among the mages of the Elementalists. The silver dragon spent three centuries contemplating a low-level spell used by mages known as rope trick, apparently because it violated conventional notations of the Shield, and Gaeleth's inability to conduct extraplanar travel.
During the Storm Wars, Xynosalionisis was one of many dragons activated by the Karatikan Alliance. Xynos served as the lead scout for the combined might of nearly two-hundred and fifty dragons, and watched as many of his kith and kin fought one another for either side, during the Storm Wars.
In the aftermath of the Storm Wars, came the Inquisition. Originally intended to silence the mages, the Inquisition slowly expanded to encompass the dragons, as well -- and brought about the Dragon Wars of 867 Avard, later to be known as the First Crusades. Xynos watched as many of his kind were slaughtered, rousing from nearly a century's slumber to feed and eat. As a ranger, Xynos managed to ration his food, hunt in secret, and keep a low profile -- whereas most of the dragons simply fed, battled, and attempted to mate. Old beyond his years, even then, Xynosalionisis looked on in sadness.
In 1135 Avard, Xynos was approached by a black dragon known as the Silent Wyrm. The Silent Wyrm asked only to speak with the ancient silver, and explained that she intended to create a nation of dragons. The nation's intent, she said, would be to defend in unity the few remaining dragons -- numbering less than one-hundred in all the world. Xynos declined to join the Silent Wyrm's dragon nation, fearing her dark heritage, and her intent in the face of the Inquisition. In the Third Crusade of the Inquisition, in 1201 Avard, Xynos worst fears were never realized -- for the Silent Wyrm risked her life no less than twice, to rescue dragons and dragonlings that had decided to join her call for a dragon nation. It was then, that Xynos decided to join her -- though by that time, he was old enough to admit that he was useful more as an advisor.
The Dragon Nation of Wuron S'fa was declared in late 1328, and by early 1329, the combined might of the Inquisition began to fall upon the Silent Wyrm and the dragons. Carefully laid plans, and the combined might of the dragons, looked to be not enough -- for Disciples, armies, dragon-slaying weapons, naval blockades, and assassins, all conspired against the fledgling nation.
Seeing a victory for the Dragon Nation, but at too high a cost, Xynos called upon his ancient knowledge for a spell that had not been used since the Shaping Wars. Sacrificing himself in a burst of arcane energy, Xynos died that day -- taking half of the Inquisition armies with him.
Later on that day, one of the white dragons that had revered Xynosalionisis walked across the blast crater where the ancient silver had fallen. At the heart of the crater, he found a blank Relic, waiting to be imprinted. Rather than touch the Relic, and become a Chosen, the dragon known as Villathanalast brought the blank Relic back with him to the council of dragons. There, all of the remaining dragons gathered around, and together gave rise to a god of their own -- Xynosalionisis.
