"Fancy Seeing you here, Professor McGonagall"
The tabby cat looked up at the towering wizard above her. Rather abruptly, the cat transformed into a rather stern looking witch.
"Headmaster," she replied curtly.
"Minerva, I'm afraid I have some terrible news."
"Yes, I know, the Potters. Oh, poor James and Lilly, if we ever find who betrayed them, I swear I'll-'
"Professor, that is not why I'm here."
"Oh. Oh dear, do you mean to tell me that You-Know-Who is still at large?"
The elderly wizard sighed, his tired eyes making him appear older than he was - a rather impressive feat for a man who just recently celebrated his centennial.
"No, I'm afraid it's even worse than that. You recall how Voldemort fancied himself to be the heir of Slytherin?"
"Yes, but it's absurd for anyone to think they could trace that back 1000 years. Clearly he was delusional."
"Unfortunately, my sources as the Ministry tell me that he was in fact correct."
"And they know this, how, exactly?"
"It seems that there were, hidden away in the Department of Mysteries, a number of documents indicating that Slytherin placed a rather unusual curse on the Wizarding world before he died. If an heir were ever to take up his noble work, then ancient magics would become active, severely altering the ratio between male and female births, in favor of females. We know neither why nor how he did this, though we speculate that it had something to do with a plan to breed a new, purer race of wizards. But whatever the cause, it appears that Voldemort was that heir, and the curse was activated a few years ago, though only now has it reached what we think to be it's peak, where it will likely remain. The effects are going to be devastating."
McGonagall chuckled. "Now Dumbledore, I realize you don't swing that way, but surely this is not quite the catastrophe you're making it out to be."
Dumbledore chuckled gently, but his face remained somber.
"No, I'm afraid it is. The ministry has already determined that to maintain the balance, and prevent a complete demographic explosion, some girls will have to be eliminated"
"Oh Albus, you can't mean Euthanasia?"
"I might have favored such a solution, actually, rather than what the ministry is contemplating. As of right now, they don't have the political will, but soon, mark my words, they'll have legalized the most terrible things - cannibalism, feeding young girls to monsters, you name it. And we'll have to go along with it. All of us. Including them. Including him," Dumbledore concluded, as a large man on a motorcycle carrying an infant in his arms. "To think, after surviving such horror, he and his friends will have to see their friends, girlfriends, even sisters devoured alive in front of them.
"But enough of that. Let us tend to young Harry..."
Nearly ten years later...
