I SLEPT IN THE WARM EMBRACE OF SPRINGS OF FIRE.
SPECIES: Ice Dragon
AGE: Unknown but speculated to be from the time before the fall of Valyria
ORIGIN: Unknown
MORTAL FORM: He can take the form of a mortal man with snow-white hair, though how he is able to do this is unknown. In this form he is able to create and conjure ice, however, the range and strength are weaker than that of his dragon forms breath.
There is a secondary secret passed down through the rulers of the Targaryen Family. That far in the North, sleeping in the hot springs near the Winterfell, there is another dragon. The one that created the wall itself with its dragon breath of ice, not fire. Born before the fall of Valyria, an attempt at creating a subspecies of dragon, he is the oldest of their kind now.
How he learned how to shift his form is unknown. Though many in the past before remembrance of him faded from common knowledge speculated that he learned through the very Blood Magic of the Valyerians. There are many other theories, yet which is the truth has been lost to all but him.
Now he will awaken in times of great need. Drawn from slumber by the ancient bond that links him to the Targaryen bloodline. Though if he will help is another matter. For he remembers the greater forces of evil. He remembers that his duty is not only to the bloodline of those of Valyria but also to the world.
Awoken by the sudden and violent death of Meleys he soon learned of the war that was brewing between the two factions of House Targaryen. A war that he had long dreaded, for the power of his kind was not easily matched in the world and yet unlike dragons, mortal men have proven to turn against their own blood. Drifting down from the north like a storm of ice and snow Xiang Liu went to the heir that had been chosen to warn her of the consequences that such a war could bring about.
He felt them. Felt the ripple of magic that emanated across the lands upon their birth from the fires of sacrifice. Drawn back to life by the blood and call of the one who was promised. Ancient magic and blood wielded on instinct to return Dragons to the world. Yet he could not go to her.
For other powers were stirring. Awakening within the far reaches of the North. One's as ancient as his kind and just as deadly. Yet there was another of the blood. A secret that perhaps on he and his new brethren would be able to sense. A child of house Targaryen hidden behind the name Snow.
And so he went to him. Hiding the truth of what he was, for the time was not yet right and the boy was not yet a man.
In this verse Xiang Liu only has one head. His size when in dragon form now is larger than Vhagar and yet slimmer. Closer to what Caraxes would have looked like had he grown to a similar size during his lifetime. His scales shimmer a cold silvery blue with darker undertones and his breath is not of fire but ice.
