So whats happened a decade on?
Well about a week after Emma and Frank did it,Frank was slain by a posse of hunters
sent out to retrieve Emma.
That left the 200 pound dragoness as the only one of her kind.
She was far too small and young to lay an egg,yet the forces within her
were still working on her
She fled the cave before the hunters arrived,and quickly discovered those
awkward wings didn't have the muscle development to lift her off the ground.
So she ran along the ground till she came to Frank's scaly carcass.
He'd been shot out of the sky and plunged into a crevice in the mountains,where
his body had lain hidden and preserved by the cold.
Emma's draconic body and instincts were a bit weak at that point
but she knew is dragonhood might contain the seed to repopulate the species.
However the necessary organ was missing.
Obviously someone else had found the item and had cut it off
from the dead man-dragon.
