I don't own Harry Potter.

Prologue

It was a day Dumbledore would never forget.

25th June 1981, the term would end in a few days. Professor Chronis, the old Divination teacher, had decided to retire, so Hogwarts was in need of a Divination teacher. Dumbledore had received a letter from Sibyll Trelawney, the great-great granddaughter of a very famous seer. He went to a bar at Hogsmeade to meet the applicant.

The meeting however, was not very pleasant. It seemed that Trelawney didn't have her ancestor's gift. She was a fraud.

As Dumbledore turned to left, a loud, harsh voice stopped him.

"The one with great power approaches..."

Startled, Dumbledore turned back to her. Trelawney had gone rigid in her chair, her eyes unfocused.

"Excuse me, Miss Trelawney?" said Dumbledore.

Trelawney didn't respond. Her eyes had rolled into her head. She spoke again in the same harsh voice.

"The one with great power approaches...
Born to those who have thrice defied the Dark Lord,
Born as the seventh month dies...
He has the gift of the shadow,
The combination of the Dark and Light...
The one with the great power will be born as the seventh month dies..."

Trelawney's head fell down to her chest before her head snapped up again.

"I'm sorry, Headmaster Dumbledore," said Trelawney in her usual dreamy voice, "I must have drifted off..."

Dumbledore's eyes twinkled. "It doesn't matter, Miss Trelawney. You just drifted off a few seconds. Now, I'd like you to be our Divination teacher. Please fill in the application form and owl to Hogwarts. I'll connect you later." said Dumbledore giving her an application form.

"Oh, I'm so glad, Headmaster...I'll do my best to teach..." babbled Trelawney.

Dumbledore didn't pay attention to her babbling, instead he muttered a farewell and turned to leave. He had many to think.

The fact that Trelawney didn't know the episode halfway through their meeting was a relief. He didn't want anyone know it. He knew it was a prophecy, he heard that whenever a true seer make a prophecy, their eyes would roll back and their voice would turn harsh. The point is: who is this mystery 'the one with great power'? In the prophecy, it is obviously a boy, a boy that born 'as the seventh month dies', which means born at the end of July. The boy would be born to parents who had already defied Voldemort three times.

Until now, couples who defied Voldemort three times are the Potters and the Longbottoms, both their sons born at the end of July. Harry Potter, son of James and Lily Potter, was born at 31st July 1980, while Neville Longbottom, son of Frank and Alice Longbottom was born at 30th July 1980. They were both nine months old.

Dumbledore knew Lily Potter was pregnant again; the due date was also the end of July, next month. If it is a boy, he will have a bigger possibility to be the prophesied one.

The prophecy said the child would be important to both sides; he had great power and would make a good ally if he was raised in the light. Dumbledore decided to find out who it is and raise him in the light, then the child would be a useful weapon against Voldemort.

No one knows who it is amongst two boys and an unborn child; only time will tell.

But now Dumbledore has something he can do: tell the Order about the prophecy.
