Magical Parallels: Year 1

It was clear that the prophecy was referring to the Potter twins. While Harry may hold the key to Voldemort's defeat, his own sister, Angeline, could be his downfall. But despite this, there is a third force at play. Someone who isn't supposed to be here but against all logic and magical forces, they alone can tip the scales in the favor of either side. Rated T just to be safe.
