A Pegasus, born on accident and left to die in the freezing blizzard of the Forbidden Ice Mountains. Adopted by Eskiponies, and then kidnapped. For 6 years of torture, she lived, until she discovered her power to create ice daggers with a wave of her hoof. Gone into hiding, for fear, until she is accepted as the Wonderbolt's student.
An Earth Pony, born to a Wonderbolt Family. Thrown out as an outcast, he ran away, finding himself at the edge of the world, and falls into a pit of lava. Amazed that he's alive, he finds he has the power to create fire and lava with a wave of his hoof. He goes into hiding, until he meets the pony of his dreams. His life seems happy, but his power still haunts him.
One mistake from both ponies, is about to change everything. Equestria is about to crumble, and they are the only ones who can stop it.
