Rogue (Inheritance series fanfiction)

"Just how," Arya spoke, each word sharply enunciated, "did you happen to lose track. Of. A. Dragon?"

It's been thirty years since the overthrowing of Galbatorix. Alagaesia was in an age of harmony. The rulers of each race were allies. All was peaceful.
Until, an egg hatched, seemingly without a rider. Which was impossible because this one had been bound for a rider. Unsure of what else to do, Queen Arya declares the dragon should be raised alongside elves and then sent to Eragon's land alone.
But the young dragon managed to escape at night.
Now, instead of her simple life of caretaking, the young female elf, Theanil, whose hand the dragon's wellbeing was placed in, must leave her home in pursuit of a runaway hatchling.
With the help of a human boy and a renowned witch, she finds the silvery dragon with her rightful rider...
Geclaz was already an outcast of his urgal tribe. When a silver mark appeared on his palm, he was even more ostracized. And now, to add to his luck, he starts hearing a voice in his head.
