Title: The Chosen Daughter, Bella Potter
Summery: I am changing D.H. a little bit. Harry is 19 and Ginny is 18, before Harry left they got married and Ginny got pregnant. Around the same time Bellitrix and Voldemort had an affair and she got pregnant. The night of the final battle, when the sun was rising and the moon was setting both children were born. Isabella Molly Lillian Potter was born facing the sun and became the instrument of all things good and pure, which meant she could change into any creature and have all the good essence. Tom Marvolo Piddle Jr. was born facing the moon and became the instrument of all things evil and had the same powers as Bella but the exact opposite. Bella and Tom both were born with scars, Bella's is in the shape of a sun with a lily bloom in it on her right elbow with vines climbing up and down her arm. Tom's is in the shape of a moon with a crow in it on his left elbow with thorns climbing up and down his arm. A prophecy was made that night by Trelawney. It says that they will have unmatchable powers but when the balance is at stake there will be a battle worse then the last.
Disclaimer: I OWN NOTHING! All this is J.K. Rowling's and Stephenie Meyer's brilliant ideas.
