Idea #1

While reading the Harry Potter fan fiction 'The Fifth House' I had an idea for another Harry Potter Story. the idea cents around the muggle repelling charm and a cure for squibs. The story would start out with a brilliant orphan whom is magical and has had a miserable life at the hands of people, who he'll later learn are muggles. Things start changing and getting better for him when he gets his Hogwarts letter and learns he is a wizard.

The muggle repelling charm could rid the world of the dangerous muggles. It couldn't be done now as the spell would have to be researched and redesigned, but it could be done sooner rather than later. The mc goes on to create a spell that will make muggles believe the planet is disappearing and shrinking slowly, making them all move to a last remaining spot and breakout fighting amongst themselves over the course of a couple years. The muggles population decreases from the fighting to lead than 50% of what it was. The muggles get tired of fighting amongst themselves and start looking for a way to save themselves as the planet they can see is still shrinking. They start trying to find a way to the moon to live since all attempts to find out what is causing the planet to disappear have failed. The muggles eventually get to the moon and watch as the planet disappears.

On the wizard side of things a potion that gives squibs magic has been created. The wizarding world works together to repel muggles to the moon. They set up spells to monitor and maintain the spell that keeps the planet hidden from muggles. Wizards find a way to have all muggle born children appear to die during childbirth, but are in reality transported to magical orphanages.
