"What are you, what are you, what are you?"
The other creature's mind was interesting, if not jumbled. From what Orphis could determine from the thought-images it shared, it was almost certainly made entirely of glass. Circling the being with an animal-like curiosity, the dragon attempted once more to figure out exactly what it was that allowed such a thing to function as a living, breathing creature. "What are you? he repeated, somewhat annoyed with its incapability to answer the simple question. Surely there was a reason for its existence.
With a puff of smoke, he made contact with the other thing's mind again, using mental images of his own to communicate what it was he wanted to know. "What made you?" Though there were uncountable amounts of magical, wondrous beasts in the lands of the Earth, many of which he'd seen, there were still thousands - or millions, perhaps - for him to see yet. But none, from the mystical unicorns of the rolling plains to the merfolk dwelling beneath the murky depths of the deep blue, had ever been so strange as to confuse Orphis.
A grunt escaping from betwixt his monstrous jaws, he slammed his tail against the ground in anger. The glass shattered, and he turned to look at the large, jagged hole in the once-smooth surface in wonder. How could a being made of a material such as this colored, clear and impossibly delicate once-sand possibly survive for more than a few hours, if that? The curiosity was beginning to drive him mad, and, unsatisfied by the thing's earlier response, he whirled on it. "Be you a magical beast? One of nature's rare errors? A... mistake?"
After a moment, Orphis forced himself to calm, and shared with the thing more images, though these were more specific. A snow-covered, mountainous landscape filled with huge winter deer and a strange sort of giant two-feet. A sunset, framed with the sky above and the crystal-clear water below, gulls and flying predators such as himself and other dragons shown as silhouettes in front of the bulging life-star that was the sun. A jungle, seemingly lifeless at first, though upon closer investigation felines and small amphibious creature could be seen cowering behind the ferns.
And then, an almost artistic representation of the glass-beast that stood before him. Illuminated from behind, as it had shown itself before, with the multicolored glass of the once-earth forming streaks as far as far as the eye could see. All of the images shown were of his own experiences; as a dragon, he would never stoop so low as to lie or misrepresent the beautiful world for fear of portraying it differently from how it actually was. He used a few words to get his next meaning across, but he was also sure to follow the message with more images to ensure that the being understood. "I have seen all this, yet... I have never seen one like you."
(I hope you like it. ^^ I thought this way, she could see that there's more to the world than glass.)
