After the first year, life became much safer. The roving bands of cannibals had become much less numerous. Now that it was safer and there was no longer an emergency need to build up food stores, people began establishing farms near Hogsmeade. The Hogwarts grounds were planted solely in wheat the second year and returned to lawns the third year.

With such a large population concentrated in one area. Hogsmeade became a major city. And such a large population of Muggles and wizards in one area meant that a Minister of Magic was no longer adequate for their governing needs. A Parliament was established with a Cabinet and Prime Minister to take care of administrative affairs.

"This meeting of the Cabinet is called to order," said Prime Minister Arthur Weasley. "I've invited the Head Mistress of Hogwarts to attend because of the unique problem we are facing. Minerva? . . ."

"Thank you Prime Minister" began Minerva McGonagall. "As you know, we have a registry of new witches and wizards. When a new one is born, their name appears in the registry. This allows us to know who to send Hogwarts letters to eleven years later. Last year, after the Change, there was a sudden upswing in the number of new wizard births. Even as the population was crashing due to starvation and cannibalism, the wizarding birth rate was exploding exponentially. There were 10,000 new witches and wizards born last year and 20,000 this year."

"We did some checking as to why this should be" began Minister of Muggles, Mike Yates. "Apparently every child born to the survivors in Britain is a Muggle-born witch or wizard."

"If this keeps up, in a few generations, there won't be any Muggles left in the world! It's you-know-who's fantasy come to life!" said Minister of Magic Rufus Scrimgeour.

"What are we going to do?" asked Minerva. "Hogwarts doesn't have the facilities to accommodate that many students."

"Britain is almost devoid of people," said Home Minister Olorin Sanford. "There are a few Scottish islands where people were able to survive, but the only large centers of population are here at Hogsmeade and the Isle of Wight, where King Charles III has set up a medieval style Muggle kingdom. He's starting to colonize the South of England. But since almost all of the livestock in Britain was eaten last year along with most of the large animals in the great dying, it's taking a while to build up the livestock that he managed to preserve on the Isle of Wight enough for expansion. We estimate that the population under the control of King Charles is about equal to our own."

"What if we established a second school, here in Hogsmead?" asked the Prime Minister. "A larger school could accommodate the excess students. We could make Hogwarts the elite school that only the most magically powerful students could get into?"

"An excellent idea Arthur" said Minerva. "This would allow us to maintain our high academic standards at Hogwarts while at the same time providing an education to all of these new Muggleborns."

"What is going to happen when we reveal our presence to the Muggles in the South?" asked Mike. "I mean most of them will have children who are students here."

"As I see it, we have three alternatives," said Rufus. "We can either bring the wizarding world out into the open . . . or . . . we can kidnap all of the children of the Muggles and bring them here for their education . . . or . . . we can let the South rot and only tend to our own children . . . "
