"Have you ever heard of an Ellanari Sky Dragon?" Tatsu hadn't moved, his eyes lightly closed and a gentle breeze caused his pale hair to sway softly. Who had heard of his kind? Not many, and probably not an elf from an isolated village. "We had a large colony, for hundreds of thousands of years, long before humans even walked this earth. Such young, impulsive creatures, humans. We pitied them, once. My kind tried to help them, but humans are greedy, selfish things. They are like children that have not yet matured."
He gave a great sigh, before turning to look at his young elven student. Tatsu's expression had not changed, but there was a profound sorrow in his pale eyes. "Once the humans learned that our very bodies were rife with magic, they hunted us, butchered us to use our parts in their spells and potions. Several thousand years ago was what we called The Great Hunt. The hunt did not stop until there were no more of us for them to kill. None but me, and I only escaped because I fled and hid. It is why I have the form you now see, and why when we do venture into civilization you will never refer to my true nature."
The Great Hunt had ended a long time ago, and no humans were left alive that would actually remember the events. He very much doubted any humans they came across would know how truly valuable Tatsu was, but he wasn't going to risk it.
