Vermithrax watched, satisfied, as the dragon turned into a tiny, humanoid, blood elf, form, her scent in blood elf form had a resemblance with dragon form, but somewhat different, he could smell some variety of scents, she was not living by herself also, she lived in a mountain region. He looked down while hearing her words.
"I couldnt tell anything that you dont know already" He said, and kept looking to that small creature while she introduced herself. he could tell that he managed to deeply involve her mind into this, thats dragon manipulation, its like they always known precisely what you want to hear, her mind seemed to be filled with doubts.
"A mount, me?" He said in a heightened tone, almost ofended as he lowered his head to get closer to the elf, the smile was gone . "Listen carefully, blood elf, if some of my kind find themselves confortable with being enslaved and mounted like mere pets, thats up to them. I, however..." And as he speak, he began to raise his upper body again, while a red light began to glow on the dragon chest and a sudden burst os flames came out of the dragons mouth towards the sky, the darkness of the night suddenly vanished and everything could be seen clearly by anyone, the flames went skyhigh before spreading and vanishing leaving everything dark again. "...am not to be confused with those" and now he had regained his calm tone again.
He did got offended, dragons can be quite sensitive and are easily angered. This time he was not particularly mad after all it was a fair question, he only wanted to state things clear to the blood elf assuming him for a mount, that was absurd to that titanic dragon.
"Yes, i remember that much, even though the origin of your shapeshifiting powers have nothing to do with the breed of two species, Strelgthar was a powerfull dragon who had the unique gift to share fragments of his power by giving his blood to one, he eventually ended up falling in love with this elfly creature, and decided to share his powers with her, they did, however had numerous children but none of them had inherited his draconic powers. What i heard is that somehow his beloved elfling died, and he decided that he did not want to live anymore, so he shared equal parts of his power to every single one of the children, until his very existenced faded off" he said while making a movement similar to a shrug "from that point on it was a genetic snowball, i guess, as every new born blood elf also inherited the draconic powers."
Vermithrax gave a small pause before speaking again he liked to move arround whoever he was talking to, and that blood elf was no exception "You said you and your sister are the only ones left, thats odd, i recall crossing paths with another of your kind a few decades ago, is she dead?"
