Preface: Fifteen Years Ago

A large moon with a reddish glow was beginning to peak over the clouds as night fell. It was a blood moon. Not many knew what that meant but at least two people did. Those people were Albus Dumbledore and Apollo Kunagnos.

The blood moon wasn't very important unless it was on Halloween. It only happened every fifteen years and both men would always check the hospitals for twin births on that night.

It was a fact that twins who were born on a blood moon would posses a gift. One that would help the whole of mankind.

For years Dumbledore and Kunagnos raced against each other to have these twins in their schools. Dumbledore had always beat Kunagnos to the birth records but there was one Halloween he didn't. It was the Halloween when Voldemort was defeated, when the Potters were killed and Sirius Black lost everything in the world dear to him. It was also the night Cassandra and Alexandra Black were born.

"One more push" A healer cried to a dark haired woman who was screaming in pain. Saint Mungo's hospital's maternity ward was unusually quiet. Only three women were currently in labour. The woman who was giving birth to her second twin daughter was alone. Her boyfriend, Sirius Black was not there. The hospital had tried to contact him but with no success. Now she was going through the final part of her labour without anyone there to support her. The woman's name was Helen Matador.

"Congratulations Ms. Matador!" The healer cried "You just gave birth to two twin girls" She was given the two girls. The first born was sleeping quietly while the other was looking around with large eyes.

Helen smiled faintly. She felt extremely woozy but happy. She had twin daughters. But their father was not there. He had been checking on the Potters. Something had happened. He would not have missed the birth of his children for some small reason.

"Ms. Matador?" A man with thinning grey hair and eyes that could only be described as kind was standing near the bed.

"Yes?" She asked weakly.

"I'm Apollo Kunagnos. I understand that you just gave birth to twins?"

Helen nodded sheepishly.

"I'm not meaning to be rude but your children may have an extraordinary gift"

"Gift?" Helen whispered.

"Yes, it's because tonight is a blood moon and it's very rare that it's on Halloween and—"he was interrupted by the twin's cries. He noticed that Helen was resting her head on her chest but her chest was not moving.

"HELP! I NEED SOME HELP!" Kunagnos shouted but it was too late.

Helen was dead.

It was short but there is a lot to come. PLEASE REVIEW!
