Twilight was questioning exactly what was happening, as she found herself practically buried beneath a good-sized dragon. It wasn't Spike, as its wings appeared to be like that of Spike's clawed hands, and on top of that, it actually had wings. She could hear the girls all shouting at the dragon, attempting to draw its attention, to no avail.
The dragon spoke, though not at native pony language first, "Him dir nu, joor." Its voice was deep, deeper than any other voice she'd ever heard. It then repeated itself, speaking in pony english this time, "You die now, mortal." It reared back, and began to speak again, "Daar Thu'um hiu dinok fen kos, iisht him kos."* He reared back further, and fire seemed to gather in his throat as his next few words shook the very town.
"YOL TOOR SHU-" He was suddenly interrupted, his dragon shout dying out, as Twilight felt something drip onto her neck. She looked up, and there appeared to be an arrow in its eyesocket, and it was now bleeding. She heard her friends gasp, and she heard applejack specifically say, "What is that?!" As Twilight watched the dragon, something ran up its back, and the dragon began to freak out, probably from being now half-blind. As she rolled out of the way, she got a good look at what may have just saved her.
It was impossible. She had just been saved by a myth in the flesh. A human.
*The dragon word "Iisht" does not truly exist, it is a filler word I had to come up with, for "food".
