Merlin's Keeper

The Dark Lord has risen once again and is looking to raise an army in his name to take over the Magical world. He will need the aid of his daughter, marked by Merlin himself, but in order to do so, she will have to be coerced into it by having to save her other half, bounded together by a age old prophecy, Draco Malfoy. Will she join her father to save Draco or do what is right?
