"A real fire-breathing dragon? Oh well..." the large scaled beast tilted their head this way and that for a moment, "Weeell..."
"You really stretched out that well," the elf noted, impatience beginning to take root.
"It's all the neck," the dragon grinned, gesturing.
"But your fire, is it real?" the elf asked, getting back to the point.
"I'm a real dragon!"
"And you breathe..?"
The real dragon wilted a bit, "...Magical illusion fire."
